Technical SEO Freelancer — Fix the Foundations That Are Quietly Costing You Rankings
You can write excellent content and earn strong backlinks and still sit on page three if the technical foundations of your site are broken. Crawl errors, slow page speed, duplicate content, and indexation failures silently undo everything else you are investing in SEO.
Why Technical SEO Is the Foundation Everything Else Depends On
Most SEO problems that look like content problems or link problems are actually technical problems in disguise. A page that should be ranking on page one but sits on page three despite strong content and backlinks often has a technical issue at the root: a crawl budget problem limiting how often Google visits it, a canonical tag pointing authority to the wrong URL, a render-blocking script delaying how quickly the page loads for Googlebot.
Technical SEO is the work that makes everything else you invest in actually land. Without it, content earns traffic it cannot hold. Links pass authority to pages that cannot rank. On-page optimisations produce ranking improvements that disappear after the next crawl cycle. Fixing the technical foundation is not the most exciting part of SEO but it is consistently the part that produces the fastest and most durable ranking improvements.
I audit, diagnose, and fix technical SEO issues across every type of site: WordPress, Shopify, Webflow, headless builds, JavaScript-heavy SPAs, and custom CMS platforms. Every finding comes with a clear explanation of what the issue is, why it matters, and exactly what needs to be done to resolve it, either by your developer or directly by me with CMS access.
What Technical SEO Covers
Technical SEO is not a single fix. It is a layered set of disciplines that all contribute to how well search engines can find, crawl, render, and rank your pages. Here is what the audit and implementation covers.
Full Site Crawl Analysis
I run a deep crawl of your entire site using professional tools and cross-reference the results with your Google Search Console data. This uncovers crawl errors, redirect chains that waste crawl budget, orphaned pages with no internal links pointing to them, and pages Google is visiting but cannot properly render or index. The crawl is the starting point that every other technical finding builds on.
Indexation Audit
Not everything on your site should be indexed, and not everything that should be indexed actually is. I identify pages that are incorrectly excluded from Google’s index due to noindex tags, canonical errors, or crawl blocks, and pages that should be excluded but are not, including duplicate content, thin pages, and parameter URLs that waste your crawl budget and dilute your ranking signals.
Core Web Vitals and Page Speed
Page experience is a confirmed Google ranking factor. I measure your LCP, CLS, and FID scores across mobile and desktop, identify the specific causes of any failures, and provide a prioritised list of fixes your developer can implement to bring your scores within Google’s recommended thresholds. Faster pages rank better and convert better simultaneously.
Redirect and Canonical Audit
Redirect chains, redirect loops, and incorrect canonical tags are some of the most common and damaging technical SEO issues. They waste crawl budget, dilute the link equity passing through your site, and confuse Google about which version of a page should rank. I identify and resolve every redirect and canonical issue across your site so authority flows cleanly to the pages that need it.
Structured Data and Schema Markup
Properly implemented schema markup enables rich results in Google’s SERPs: review stars, FAQ dropdowns, breadcrumb navigation, product pricing, and more. These rich results improve click-through rates significantly compared to standard organic listings. I implement, test, and validate structured data across your site’s most important page types using Google’s rich result testing tools.
XML Sitemap and Robots.txt
Your sitemap tells Google what you want it to crawl. Your robots.txt tells it what to avoid. Both are surprisingly easy to misconfigure in ways that have significant consequences: sitemaps pointing to redirected or noindexed URLs, robots.txt files accidentally blocking sections of your site from being crawled at all. I audit and correct both to ensure Google’s crawl budget is spent exactly where you need it.
How Technical SEO Gets Done
Technical SEO needs to be systematic. Random fixes applied without a clear picture of the full issue landscape often solve one problem while missing five others. Here is how I approach it.
Technical Crawl and Audit
I run a comprehensive site crawl using professional tools alongside a review of your Google Search Console data, Core Web Vitals report, and any existing analytics anomalies. This gives me a complete picture of every technical issue affecting your site: what it is, where it is, how many pages are affected, and how severe the impact on your rankings and crawl efficiency is likely to be.
Prioritised Fix List
Every issue found in the audit is categorised by severity and ranked by its likely impact on your rankings. Critical issues that are actively suppressing pages are flagged for immediate action. Lower-priority improvements are documented separately so your team can address them in order without being overwhelmed. You always know what to fix first and why, rather than facing an undifferentiated list of hundreds of issues.
Implementation
I can implement fixes directly within your CMS given appropriate access, or deliver developer-ready specifications with screenshots, Loom video walkthroughs, and precise technical instructions your development team can act on without needing to come back to me with questions. For issues that require both approaches, I handle what I can directly and hand off the rest with complete context.
Verification and Ongoing Monitoring
Once fixes are implemented I verify each one is working correctly using Search Console, crawl validation, and where relevant, Google’s rich result testing tools. I also set up ongoing monitoring so that new technical issues are caught quickly rather than discovered months later after they have already suppressed rankings. Technical SEO is not a one-time task and the sites that stay technically healthy are the ones with a process for catching problems early.
Questions People Ask About Technical SEO
Do I need a developer to fix technical SEO issues?
It depends on the specific issues found. Many technical SEO fixes can be made directly in your CMS without any developer involvement: updating robots.txt, fixing canonical tags, correcting sitemap errors, adding structured data via a plugin, adjusting noindex settings. Others, such as render-blocking script removal, image compression at the server level, or Core Web Vitals improvements on custom-built pages, do require developer time. I will clearly separate what falls into each category and provide ready-to-use specifications for the developer work.
How do you deliver your technical recommendations?
You receive a detailed written report documenting every issue with screenshots showing exactly where the problem exists and what the correct state should look like. For developer-facing fixes, I provide specification sheets written in language a developer can action without needing further clarification. Complex issues are accompanied by Loom video walkthroughs that explain the problem, the cause, and the solution in plain terms.
Do you work with headless or JavaScript-heavy sites?
Yes. JavaScript rendering is one of the most misunderstood areas of technical SEO and one where a lot of sites have significant hidden problems. Single-page applications and JavaScript-rendered content can appear perfectly functional in a browser while being partially or completely invisible to Googlebot. I audit how your site renders for search engines specifically and identify any content or links that are not being properly crawled or indexed as a result of JavaScript rendering issues.
How long does a technical SEO audit take?
Most sites are audited and delivered within five to seven business days from the point access is granted. Larger enterprise sites with complex architectures, thousands of pages, or heavily customised technical configurations may take longer. If you have a specific timeline, let me know when you get in touch and I will confirm whether I can accommodate it before we begin.
My site seems to work fine. How do I know if I have technical SEO problems?
A site that works fine for human visitors can have significant technical SEO problems that are invisible to anyone browsing it normally. Googlebot does not experience your site the way a human does. It cannot execute all JavaScript, cannot log in to access content, has a limited crawl budget it allocates across your site, and processes pages differently depending on how they are served. Many of the most damaging technical issues, including crawl budget waste, partial indexation failures, and authority dilution from redirect chains, produce no visible symptoms in the browser whatsoever. The only way to know for certain is to audit.
