Every campaign we take on starts the same way, and it isn't with keyword research or content planning. It starts with a technical pass through the site itself, because building visibility on top of a site that Google can't properly crawl or render is a bit like decorating a house before checking the foundations are sound. We've learned this the hard way over the years, watching campaigns underperform not because the strategy was wrong but because something underneath it was quietly working against every other effort being made. So before a single blog post is written or a single backlink is pursued, we go through a structured technical review, and it's worth explaining exactly what that involves, because most business owners have never seen behind that particular curtain, and understanding it usually changes how they think about the rest of the campaign that follows.
Crawlability and Indexing First
The very first thing we check is whether search engines can actually access and index the pages that matter. We pull the site through a crawler the same way Googlebot would encounter it, checking robots.txt for accidental blocks, reviewing the XML sitemap for accuracy, and comparing the number of pages that should be indexed against the number that actually are in Google's own index. It's surprisingly common to find entire sections excluded by a stray noindex tag left over from a staging environment, or a sitemap that still references pages deleted two redesigns ago. None of this is visible to a normal visitor browsing the site, which is exactly why it goes unnoticed for so long, sometimes for years, quietly capping how much of the site Google is even willing to consider ranking. We've opened accounts where a third of a client's pages had simply never been seen by Google at all, despite the site looking entirely complete to anyone browsing it normally.
Server Response Codes and Redirect Chains
Next we check how the server actually responds to requests, page by page. Broken links returning soft 404s, old URLs redirecting through three or four hops before reaching their destination, and pages returning a 200 status code when they should be returning a proper error, all of these confuse search engines about which version of a page deserves to rank. Redirect chains in particular are a quiet drain on what SEOs call crawl budget and link equity, because each extra hop dilutes some of the value being passed through. Cleaning these up is unglamorous work, but it's foundational, and it's one of the clearest examples of a fix that costs almost nothing to implement yet removes friction that's been sitting there for years, sometimes since the last time anyone touched the site's structure at all.
Mobile Rendering and Usability
Google has indexed the mobile version of most sites for years now, not the desktop version, so we test how every template renders on an actual phone rather than a resized browser window. Menus that don't open properly on touch screens, text that requires zooming to read, and buttons placed too close together to tap accurately are all things we log carefully. We've opened sites that looked polished on a laptop and were genuinely difficult to navigate on a phone, which matters enormously given how much local search happens on mobile devices, often from someone standing outside a shop or searching while driving to an appointment nearby. A form that's fiddly to complete on a small screen can quietly cost a business enquiries that never show up as a measurable bounce in analytics, simply as visitors who gave up halfway through.
Core Web Vitals and Page Speed
We measure load speed, visual stability, and interactivity using the same metrics Google uses to judge page experience, because these numbers increasingly influence rankings directly rather than just affecting how a visitor feels about the site. Oversized images, render-blocking scripts, and bloated third-party tracking tags are usually the biggest culprits, and they're rarely obvious without actually testing under realistic conditions rather than on a fast office connection. This kind of groundwork is a core part of the technical SEO work we carry out for Colchester businesses, because a beautifully written page that loads slowly on a mid-range phone will lose visitors before they ever read a word of it, no matter how much time went into writing that page in the first place.
Structured Data and On-Page Metadata
We audit every page's title tags, meta descriptions, header structure, and any schema markup already in place, checking for duplication, missing tags, and structured data that's technically present but implemented incorrectly. Schema in particular is easy to get wrong in a way that looks fine to a human eye but fails validation entirely, quietly switching off rich results the business could otherwise be earning in search listings. We've found review schema pointing to the wrong product, FAQ markup duplicated across dozens of unrelated pages, and organisation schema still listing an address the business moved away from three years earlier, none of which anyone would spot without deliberately checking the underlying code rather than the rendered page.
Site Architecture and Internal Linking
We map how the site's pages actually link to one another, looking for orphaned pages with no internal links pointing to them at all, and for important service pages buried four or five clicks from the homepage. A flat, logical structure where the most commercially valuable pages sit close to the top of the site hierarchy tends to perform far better than a deep, sprawling one, and this is usually one of the easier structural problems to fix once it's been properly mapped out rather than guessed at. We often find the page a business most wants to rank sitting several layers deep behind a generic menu structure nobody designed with search in mind.
- Duplicate content across parameter-based or printer-friendly URL versions
- HTTPS misconfigurations and mixed content warnings
- Missing or inconsistent canonical tags across similar pages
- Broken internal links left over from previous content changes
Security and Hosting Fundamentals
Finally, we check the basics that tend to get taken for granted: a valid SSL certificate, a hosting environment that responds quickly and consistently, and no security warnings that would make a visitor or a search engine trust the site less. These aren't exciting checks, but a site flagged as insecure, even briefly, can lose visitor trust and search visibility that takes far longer to rebuild than it took to lose. Getting this right from the outset through a proper technical audit means every subsequent piece of campaign work actually has a stable foundation to build on, rather than fighting against problems that were there all along.
The Bottom Line
None of these checks are individually dramatic, and that's rather the point. Technical SEO is mostly about removing small pieces of friction that, left unaddressed, quietly cap how well everything else performs. We run this full review before a campaign starts because it tells us exactly where the genuine opportunities sit, rather than starting with assumptions and discovering the real obstacles months later, once budget has already been spent trying to work around problems that could have been fixed on day one. A site that passes this review isn't necessarily perfect, but it's finally ready to let the rest of the campaign do its job properly.
