Technical SEO
The engine room of your visibility, put in order by people who build websites themselves.
Technical SEO covers everything search engines and AI crawlers need to find, read and display your website: speed, crawlability, indexation and structured data. It is the engine room beneath your content. A strong page on a slow or unreadable site is a good answer that never gets retrieved.
We approach technical SEO as builders, not just as analysts. Because we develop websites ourselves, an audit does not stop at a report of findings. We fix the problems we find, in the code itself when needed.
The technical SEO checklist we run through in every audit
Every audit starts with the same fixed inspection. Not because every site has the same problems, but because you can only prioritise once you have seen everything. These are the parts:
- Core Web Vitals: load time, interactivity and visual stability on real devices
- Crawlability: robots.txt, internal link structure, crawl budget and error pages
- Indexation: which pages are in Google, which are missing and which should not be there
- Structured data: schema markup that gives search engines and AI models context
- Canonicals and duplicates: one address per page, no competing with yourself
- Mobile and HTTPS: the basics that still turn out broken surprisingly often
The result is not a scorecard but a ranked worklist: what is costing you visibility right now, what can be fixed in a day, and what needs a structural intervention.
Core Web Vitals: where the slowness really comes from
On most sites we examine, the biggest slowdown does not come from hosting but from marketing scripts nobody uses anymore: old pixels, duplicate analytics tags, chat widgets from a tool that was cancelled long ago. Cleaning those up often gains more than a more expensive server would.
After that we look at images, fonts and the order in which the page loads. For Endura Coaching we rebuilt a site made in an AI building tool that was not performing: the technical health score went to 98 percent and PageSpeed scored 100 on SEO and best practices. Speed is measurable, which means it is accountable.
Wondering what this means for your site?
Ask usCrawlability and indexation: being found starts with being read
A page that never gets crawled does not exist for Google. And now that AI search engines send their own crawlers, this counts double: GPTBot and PerplexityBot need to read your site as easily as Googlebot does. We check that your robots.txt does not accidentally lock them out and that your most important pages sit within a few clicks of the homepage.
Indexation problems tend to hide in the edges: filter pages generating thousands of URL variants, expired campaign pages that live on, or a migration where redirects were forgotten. At Dakwerken Roofit, the technical foundation was the first step of an engagement that ended at twenty percent more enquiries per week.
Structured data: context for Google and for AI models
Structured data tells machines what a page contains: this is a company, this is a service, this is a frequently asked question with this answer. Google uses it for rich results. AI models use it to summarise and cite your content correctly.
We implement schema markup per page type, not as a box-ticking exercise: organisation and service markup on service pages, FAQ markup where real questions get answered, article markup on knowledge pages. Wrong or inflated markup damages your credibility with search engines, so we only mark up what is actually on the page.
What does a technical SEO audit cost?
The price of technical SEO work depends on the size and state of your site: a twenty-page brochure site is a different project than a webshop with ten thousand products and its own filtering system. It also matters whether we implement the fixes ourselves or hand them to another development team.
We work with a fixed fee per audit and a fixed monthly fee for ongoing maintenance, without lock-in. The starting point is a first conversation: tell us your situation, we dig into your site and come back with insights and what fixing the problems is expected to deliver. Then you decide whether you want a proposal. Curious about the bigger picture? Read our page on outsourcing SEO.
Frequently asked questions
Everything that touches the engineering of your site: speed and Core Web Vitals, crawlability, indexation, structured data, canonicals, redirects, mobile friendliness and HTTPS. Content and link building fall outside it, but lean on it: without a technical foundation, even good content underperforms.
Warning signs are rankings dropping without a clear reason, pages not appearing in Google, warnings in Search Console, or a site that feels noticeably slow on your phone. Tell us your situation and we make it concrete: we dig into your site and come back with which problems exist and how much they weigh.
Both. The initial clean-up is a project with a beginning and an end. After that, maintenance remains necessary: every new page, plugin or campaign can break something, and the requirements of search engines and AI crawlers keep shifting. We do both, separately or combined.
Yes, and increasingly so. AI search engines send their own crawlers that need to fetch and understand your site. A blocked crawler, slow server or unreadable HTML structure means your content never makes it into their answers, however good it is.
Yes. That is exactly why clients choose us: we build websites ourselves, so an audit does not end with a PDF landing on another development team's pile. If your site runs on a platform managed by someone else, we deliver the fixes as concrete, executable tasks.
An intro call is usually scheduled within days; for the full picture, access to Search Console helps. An engagement typically starts two to three weeks after sign-off. Send your question through the form below and we will reply within one working day.
