It may look very different to a search engine. We find the gap between the two, in the order that actually matters, so your developer knows what to fix first and why. - Diagnosed in dependency order - Written for developers - We publish our own audit - Findings are yours to keep Last Updated: October 1, 2026 [Request a technical audit](/consultation/) [Or call 855-473-6582](tel:855-473-6582) ![Image 2](https://leadtoconversion.com/wp-content/uploads/Image-2.svg "Image") ![Rectangle 61](https://leadtoconversion.com/wp-content/uploads/Rectangle-61.webp "Rectangle 61") ## What Is a Technical SEO Audit? **A technical SEO audit is a diagnostic of the machine-facing layer of your website: whether search engines can reach your pages, render them the way a browser does, index them correctly, and consolidate duplicate versions into a single ranking URL.** It deliberately excludes content strategy, keyword targeting and link building, because those only matter once the machine layer works. The output is a list of defects ordered by dependency rather than by severity score, so the issues blocking everything else get fixed before the cosmetic ones. Technical audits usually produce the fastest measurable improvement in search performance, because they recover visibility a site has already earned but is not being credited for. ![Rectangle 60 6](https://leadtoconversion.com/wp-content/uploads/Rectangle-60-6.webp "Rectangle 60") ## TL;DR ![icon number](https://leadtoconversion.com/wp-content/uploads/icon-number.webp "icon-number") #### There are two versions of your website. The one you see in a browser and the one a search engine assembles. Technical SEO is the work of closing the gap. ![icon number 1](https://leadtoconversion.com/wp-content/uploads/icon-number-1.webp "icon-number (1)") #### Findings have a dependency order. If a page cannot be crawled, nothing about its content matters. Most audits ignore this and list everything flat. ![icon number 2](https://leadtoconversion.com/wp-content/uploads/icon-number-2.webp "icon-number (2)") #### We publish the technical audit of our own website. Real defects we found on leadtoconversion.com, including the embarrassing ones. Scroll down. ![icon number 3](https://leadtoconversion.com/wp-content/uploads/icon-number-3.webp "icon-number (3)") #### Rendering is where modern sites break. Content loaded by scripts, third-party widgets and lazy-loading is frequently invisible to search engines while looking perfect to you. ![icon number 4](https://leadtoconversion.com/wp-content/uploads/icon-number-4.webp "icon-number (4)") #### Index bloat is as damaging as missing pages. Thousands of thin URLs dilute the authority that should sit behind the pages you care about. ![icon number 5](https://leadtoconversion.com/wp-content/uploads/icon-number-5.webp "icon-number (5)") #### This is not a full SEO audit. If you want content, authority and competitive analysis too, start with our [full SEO audit](https://leadtoconversion.com/seo-audit-services/) instead. ![icon number 6](https://leadtoconversion.com/wp-content/uploads/icon-number-6.webp "icon-number (6)") #### Written for whoever does the work. Every finding comes with a reproduction step, a fix, and a way to verify it worked. ## The Dependency Ladder: Why the Order of Findings Matters More Than the List Almost every technical audit you can buy presents its findings sorted by a severity score. Critical, high, medium, low. That looks organised and it is quietly useless, because severity says nothing about sequence. Search visibility is a chain of dependencies. Each link has to hold before the next one means anything. Fixing a rung above a broken one produces no result and everybody concludes SEO does not work. RungThe questionIf this failsWhat we check**1. Reach**Can a search engine request the page at all?Nothing else on this list matters. The page does not exist to search.robots.txt rules, server response codes, redirect chains, hosting reliability, crawl efficiency**2. Render**Once fetched, does the page assemble the same content a browser shows?Your content is invisible even though the URL resolves. Pages read as thin or empty.JavaScript execution, script-injected content, lazy-loading behaviour, third-party embeds, blocked resources**3. Index**Does the search engine choose to store the page?The page is crawlable and renderable but never appears in results.Robots meta directives, X-Robots-Tag headers, quality thresholds, index bloat, sitemap accuracy**4. Consolidate**Do all versions of this page collapse into one ranking URL?Your own pages split authority between them, so none of them rank.Canonical logic, parameter handling, duplicate templates, protocol and trailing slash variants, internal cannibalization**5. Qualify**Does the page meet experience and structured data expectations?The page ranks, but below its potential, and loses rich results.Core Web Vitals from field data, mobile parity, structured data validity, internal link equity Every finding we deliver is tagged with its rung. That single change to how an audit is presented is usually the difference between a document that gets implemented and one that gets filed. **What this means for you:** your developer opens the report and knows immediately that the three rung-one items must ship before anything else is worth doing. No debate about priorities, no guessing. ## We Published the Technical Audit of Our Own Website Agencies love to tell you what they would find on your site. Very few will tell you what is wrong with their own. We think that is backwards, so here is a genuine extract from the technical audit we ran on leadtoconversion.com, including the findings that were uncomfortable. RungWhat we found on our own siteWhat it was costing us**1. Reach**Every XML sitemap was returning a 404 while robots.txt continued to advertise them.We were pointing Google at a dead file on every single crawl, slowing discovery of everything new we published.**1. Reach**One of our most commercially important pages carried a page-level directive telling search engines not to follow any link on it.Every internal link on that page had stopped passing value. It had been that way since a relaunch and nobody had checked.**2. Render**Our testimonials loaded through a third-party widget inside an iframe.Zero indexable social proof on pages where trust drives the conversion. The section looked full to us and empty to Google.**3. Index**A parameter-tagged version of our homepage was indexed and outranking the service pages built to convert.More than 12,000 impressions across high-intent commercial queries were landing on the wrong URL.**4.Consolidate**Twenty of twenty-five pages sampled carried two structured data nodes claiming the same identifier with conflicting values.Search engines were resolving the conflict unpredictably. Our rich result eligibility was a coin flip.**5. Qualify**Dates in our structured data were written as “June 7th, 2021” rather than a valid date format.Invalid values across the site, silently ignored, on markup we had gone to the trouble of adding.**5. Qualify**Eighteen of twenty-five pages had no social sharing image, and our reading-time metadata was overstating length by five to ten times.Unshareable pages, plus a strong signal that duplicated markup was bloating every template on the site. Two things are worth saying about that list. First, none of it was visible from the front end. The site looked, and still looks, perfectly healthy in a browser. That is exactly the point of a technical audit. Second, we found it because we applied our own process to ourselves rather than assuming we were fine. If an agency has never audited its own site, ask them why. **What this means for you:** the same method that surfaced these on our site is what we will point at yours. You will get the same directness, including the findings you would rather not hear. ## The Two Websites Problem Here is the mental model that makes technical SEO make sense. When you visit your website, your browser downloads the HTML, runs every script, loads fonts and images, waits for third-party widgets, and assembles the finished page. You see the result of all that work. A search engine does something related but not identical. It fetches the HTML, decides whether to spend the resources rendering the scripts, may render later or not at all, may time out waiting for a slow third-party call, and builds its own version of the page from whatever it managed to assemble. Most technical SEO defects live in the difference between those two versions. Common examples we find: - **Content that only exists after a script runs.** Tabs, accordions and product details injected by JavaScript. Sometimes indexed, sometimes not, and rarely predictable. - **Third-party widgets holding your content.** Reviews, testimonials, booking tools and galleries served inside an iframe are not your content as far as search engines are concerned. - **Lazy-loading that hides rather than defers.** Implemented properly it improves speed. Implemented poorly it means content below the fold is never seen by a crawler. - **Blocked resources.** A CSS or JavaScript file disallowed in robots.txt can stop a page rendering correctly, so the search engine judges a broken version of your layout. - **Mobile and desktop serving different content.** Google indexes the mobile version. If your mobile template drops content, that content effectively does not exist. We test the rendered version, not just the source, because that is the version being judged. ![Placeholder Image 1 5](https://leadtoconversion.com/wp-content/uploads/Placeholder-Image-1-5.webp "Placeholder Image (1)") ## What Our Technical SEO Audit Examines ### Crawl behaviour and server response How search engines actually move through your site, which URLs consume the most crawling attention, and whether anything valuable is being reached slowly or not at all. Google’s documentation is explicit that [when a site responds slowly or returns server errors, it gets crawled less](https://developers.google.com/crawling/docs/crawl-budget). On larger sites that alone can keep new pages out of the index for weeks. Where server log access is available, we use it. Logs show you what search engines actually did rather than what a crawler simulation predicts, and they routinely reveal that a large share of crawl activity is being spent on URLs nobody wants indexed. ### Rendering and JavaScript We compare the raw HTML against the rendered DOM to identify content, links and metadata that exist for visitors but not for search engines. This is the single most under-examined area in the audits we review, and on modern sites it is where the largest recoverable losses tend to be. ### Indexation control Which of your pages are indexed, which are not, and whether that matches your intent in both directions. Missing pages are the obvious problem. Index bloat is the quieter one: thousands of thin, filtered, paginated or auto-generated URLs competing for the attention that should go to your commercial pages. ### Canonicalization and duplicate consolidation Whether every version of a page collapses to one ranking URL. We check [canonical implementation](https://developers.google.com/search/docs/crawling-indexing/consolidate-duplicate-urls), parameter handling, protocol and trailing slash variants, and internal cannibalization where two of your own pages target the same query and neither wins. ### Site architecture and internal link equity How deep your important pages sit, whether authority flows to them or pools somewhere useless, and whether any page is orphaned. We map click depth against commercial value and show you where the mismatch is. ### Core Web Vitals from real visitors Google measures three things from actual visits, published as [Core Web Vitals](https://web.dev/articles/vitals): MetricTargetTypical cause when it failsLargest Contentful PaintUnder 2.5 secondsAn oversized hero image, slow server response, or render-blocking resourcesInteraction to Next PaintUnder 200 millisecondsHeavy JavaScript occupying the main thread when someone tapsCumulative Layout Shift0.1 or lessImages or embeds without reserved dimensions, or late-loading banners These are assessed at the 75th percentile of real visits, which is why a green score in a lab tool can sit alongside a failing site. We diagnose from field data and trace each failure to the specific element causing it. ### Structured data validity and consistency Whether your [structured data](https://developers.google.com/search/docs/appearance/structured-data/intro-structured-data) is valid, non-conflicting, and consistent with what the page actually says. Duplicate identifiers, invalid date formats and orphaned nodes are extremely common on content management systems where a plugin and a custom template are both writing markup. ### Migration and deployment risk If you have recently launched, replatformed or are about to, we check for the specific failure modes that cause post-migration traffic loss: unmapped redirects, staging directives shipped to production, lost internal links, and changed URL patterns without consolidation. ## Is a Technical Audit the Right Thing for You? Being straight about this saves everyone time. A technical audit is a narrow instrument. It is the right one in specific circumstances and the wrong one in others. Your situationWhat you needTraffic dropped after a redesign, migration or platform change**Technical audit.** This is the clearest case there is.New pages take weeks to appear in search, or never appear**Technical audit.** Almost always a reach, render or index problem.Search Console is reporting coverage or indexing errors you do not understand**Technical audit.**You are about to rebuild and do not want to inherit existing defects**Technical audit,** before the build rather than after.You publish good content and it simply does not rank**Technical audit first,** then content work if the machine layer is clean.You want to know whether your SEO investment is working overall[**Full SEO audit.**](https://leadtoconversion.com/seo-audit-services/) Technical is one part of a bigger question.You need to know which content to create next[**Full SEO audit.**](https://leadtoconversion.com/seo-audit-services/) Content gap analysis is not part of a technical audit.You need strategic direction rather than a diagnosis[**SEO consulting.**](https://leadtoconversion.com/seo-consulting/) If you are not sure which row you are in, tell us the symptom and we will tell you honestly which service fits. We would rather point you at the cheaper option that works than sell you the bigger one that does not. ## What You Receive Every finding in your report carries four things. This format exists because we got tired of watching good audits die in a shared drive. ComponentWhat it gives your team**Rung**Where the defect sits on the dependency ladder, so sequencing is decided before anyone opens a ticket**Reproduction**The exact URL, request or tool output that demonstrates the problem, so nobody has to take our word for it**Fix**Specific instructions written for a developer, referencing your actual platform rather than generic advice**Verification**How to confirm the fix worked, so the ticket can be closed with confidence rather than hope You also get a live walkthrough with your developer, a recording of it, and the underlying data. The findings are yours to keep and hand to anyone, including another agency. ![Placeholder Image 19](https://leadtoconversion.com/wp-content/uploads/Placeholder-Image-19.webp "Placeholder Image") ## What fixing the machine layer produces - ## 74% #### Increase in Conversion Value Cutting Ad Costs While Boosting Conversion Value: A Q1 2025 Success Story [View Case Study](https://leadtoconversion.com/case-studies/ecommerce-ppc-increased-conversion-value/) - ## 30% #### increase in clients Case Study: Google Ads Boost GBP Leads [View Case Study](https://leadtoconversion.com/case-studies/google-ads-gbp/) - ## +534 #### Organic Search Rankings Case Study: Improving Organic Search Rankings for our Concierge Doctor Client [View Case Study](https://leadtoconversion.com/case-studies/concierge-doctor-local-search-campaign/) Technical work produces the fastest movement of anything in search, because you are not building new demand. You are collecting visibility the site already earned and was not being credited for. ![Placeholder Image 2 3](https://leadtoconversion.com/wp-content/uploads/Placeholder-Image-2-3.webp "Placeholder Image (2)") ## What a Technical SEO Audit Costs We scope technical audits individually and give you a fixed number before any work starts. The main variables: VariableWhy it changes the number**URL count**The dominant factor. A 60 page site and a 40,000 URL catalogue are different exercises entirely.**Rendering complexity**A server-rendered site is straightforward. A single page application needs render testing at a different depth.**Log file access**Available logs make the audit more accurate and add analysis time. Worth it on larger sites.**Migration context**Auditing across a migration means comparing two states, which is more work than assessing one.**Internationalization**Multi-language and multi-region sites add hreflang and regional consolidation to the scope. For market context, agencies publishing technical audit pricing tend to start around $2,500 for a small to mid-size site, and enterprise engagements run well into five figures. Anything advertised at a few hundred dollars is a tool export with a cover page, which you can generate yourself for free. If the audit points toward ongoing work, our SEO programs start at $750 per month per location for local campaigns, $1,500 per month regional and $3,500 per month national. Details on our [pricing page](https://leadtoconversion.com/pricing/). There is no obligation, and the findings are yours regardless. ## What Is the Recovery Actually Worth? Technical audits have an unusually clean return calculation, because you are not forecasting new demand. You are estimating how much of your existing, already-earned visibility is being lost to defects. **Assumptions you should replace with your own** - **Recovery range:** 15% to 40% of current organic traffic where meaningful technical suppression exists. A clean site recovers little, and we will tell you if that is what we find. - **Conversion rate:** 2%. Use your real figure. - **Value per conversion:** $1,000. Use your real figure. This moves the model more than anything else. - **Timing:** reach and index fixes often show within 30 to 60 days. Consolidation and experience work takes longer to settle. ![Placeholder Image 1 4](https://leadtoconversion.com/wp-content/uploads/Placeholder-Image-1-4.webp "Placeholder Image (1)") ### Where the Recovery Usually Comes From Defect classTypical share of the recoveryWhy**Reach and index blocks**LargestPages going from invisible to visible is a step change, not an increment**Consolidation fixes**SubstantialMerging split authority often lifts a page several positions at once**Rendering fixes**VariableEnormous where content was invisible, negligible where it was not**Core Web Vitals**Smallest, but compoundingAffects conversion of traffic you already have as much as ranking ### Recovered Annual Value by Site Size Current organic sessions per monthRecovered at 15%Recovered at 40%Added annual value1,000150 sessions400 sessions$36,000 to $96,0005,000750 sessions2,000 sessions$180,000 to $480,00020,0003,000 sessions8,000 sessions$720,000 to $1,920,000 **The honest caveat.** This assumes defects exist. Some sites are genuinely well built, and for those the right answer is that a technical audit is not your bottleneck. We will say so and point you somewhere more useful rather than inventing findings to justify a fee. [Find Out What Your Site Is Losing](/consultation/ "Find out what your site is losing") ## Technical SEO Audit Questions [How do I know if I need a technical audit or a full SEO audit?](#432fe4d27875bfdf4) Ask yourself what question you are trying to answer. If it is “something is broken and I do not know what,” you need a technical audit. Symptoms include a traffic drop with no obvious cause, pages that will not index, coverage errors in Search Console, or performance that got worse after a redesign. If your question is “is my SEO investment working and what should I do next,” you need a full SEO audit, because that requires content, authority and competitive analysis alongside the technical layer. When in doubt, describe the symptom to us and we will tell you which one fits. Starting with the narrower service is usually cheaper and often sufficient. [Why does my page look fine to me but not to Google?](#7a72a2f2fda851f1e) Because you and a search engine are looking at two different versions of the page. Your browser downloads the HTML, executes every script, waits for third-party widgets and assembles the finished result. A search engine fetches the HTML, then decides whether and when to spend resources rendering the scripts, and may time out on slow external calls. Content injected by JavaScript, loaded inside an iframe, or deferred by a poorly implemented lazy-load can be completely absent from the version being judged. This gap is where most modern technical defects live, and it is why we test the rendered output rather than trusting the source code. [Do you need access to my server logs?](#61a42cc74bfa4c7d0) Not required, but valuable, especially on larger sites. Server logs are the only record of what search engines actually did rather than what a crawler simulation predicts they would do. They reveal which URLs are consuming crawl attention, whether important pages are being visited rarely, and whether bots are hitting errors that never appear in a standard crawl. On sites under a few hundred pages the added value is modest. Above a few thousand URLs, logs frequently expose that a large share of crawl activity is going to parameters, filters or pagination that nobody wants indexed. If logs are difficult to obtain, we work without them and say so in the report. [My pages are indexed but not ranking. Is that a technical problem?](#c2bd5db6ff67bb0fe) Sometimes, and it is worth checking before assuming it is a content problem. The most common technical causes are consolidation failures, where several of your own URLs target the same query and split the authority that should sit behind one, and internal linking problems, where your commercially important pages sit too deep or receive almost no internal links. Rendering issues can also make a substantial page look thin to a search engine. That said, if the machine layer is clean, then indexed-but-not-ranking is usually a content, intent or authority question, which is the territory of a full SEO audit rather than this service. [How many URLs can you audit?](#2a99b26097c9664e2) There is no hard limit. We have audited sites from twenty pages to several hundred thousand URLs. What changes with scale is method rather than possibility. Small sites can be examined comprehensively, page by page. Large sites are audited through statistically representative sampling by template and URL pattern, combined with full-site crawl data and log analysis, because inspecting 200,000 URLs individually would cost more than it could ever return. We tell you during scoping which approach your site calls for and why. [Can my own developer do this instead?](#f1c4033ef314adc79) Parts of it, and if you have a strong developer you should absolutely have them fix what we find rather than paying us to do it. The distinction is diagnosis versus implementation. Most developers are excellent at implementing a clear specification and have simply never had a reason to learn how search engines crawl, render, consolidate and index, which is a specialist body of knowledge rather than a general competence. The most efficient arrangement we see is that we diagnose and specify, your developer implements, and we verify. That usually costs less than either party doing the whole job alone. [Will a technical audit recover traffic lost to a Google algorithm update?](#0b8ad1b46f5cfdbe5) Usually not directly, and it is important to be clear about that. Core algorithm updates typically reassess content quality, relevance and trust rather than technical implementation, so a technically perfect site can still lose visibility in an update. What a technical audit does contribute is ruling out the alternative explanation. Traffic drops are frequently blamed on an algorithm update when the actual cause was a deployment that shipped in the same week. Establishing whether the drop correlates with an update or with a change to your own site is genuinely useful, and it is one of the first things we check. [What breaks most often during a website migration?](#99f32b687c2e85976) Four things, in roughly this order of frequency. Unmapped redirects, where old URLs return errors instead of pointing at their replacements, which is the single most common and most damaging. Staging directives shipped to production, meaning the blocking rules that kept the development site out of search go live with the real site. Lost internal links, where a new template quietly drops the navigation or contextual links that were distributing authority. And changed URL patterns without consolidation, creating duplicate versions of pages that then compete. All four are preventable with a pre-launch audit, and all four are recoverable afterwards, though recovery costs more than prevention. [Is index bloat actually a problem if the extra pages are harmless?](#eb446436d92d846d0) Yes, for two reasons. The first is crawl efficiency: attention spent fetching thousands of filtered, paginated or auto-generated URLs is attention not spent on the pages you care about, which on larger sites measurably slows how quickly new content gets discovered. The second is quality assessment. Search engines form a view of a site as a whole, and a domain where most indexed URLs are thin is judged differently from one where most are substantial. Neither effect is dramatic on a small site. Both become significant past a few thousand URLs, which is where most ecommerce and large content sites sit. [How long before I see results from technical fixes?](#52dc1e2ea2c8234bd) It depends which rung the fix sits on. Reach and index fixes, such as removing an accidental block or repairing sitemaps, often show within 30 to 60 days, sometimes faster if the affected pages already had authority. Consolidation fixes take longer because search engines need to recrawl and reassess the merged signals, typically 60 to 90 days. Core Web Vitals improvements are assessed over a rolling 28 day window of real user data, so the measured result always lags the actual fix by about a month. We tell you the expected timeline per finding rather than giving one number for the whole engagement. ## Tell Us the Symptom Send us your website and describe what you are seeing. We will do an initial technical review and come back with what we find, which rung it sits on, and whether a full technical audit is worth your money. No cost for that first look, and no obligation after it. - An initial review of reach, render and index health - An honest answer on whether this is your bottleneck - A fixed scope and price before any work begins - Findings written for whoever will implement them [Request a Technical Audit](/consultation/ "Request a technical audit") [Or call 855-473-6582](tel:855-473-6582 "Call 855-473-6582") **If your site is technically clean, we will tell you.** That is a legitimate finding and you will not be charged for a longer engagement to reach it. ***Written by Matthew Travers**, President, Lead to Conversion.
