Technical SEO Services
Crawlability, indexation, Core Web Vitals, and schema — the foundation that decides whether the rest of your SEO work even gets seen.
Technical SEO in short: Technical SEO is making sure search engines can crawl, render and index your site efficiently. Contomatix runs a full-site audit covering crawl paths, indexation gaps, Core Web Vitals, schema, redirects, canonicals and architecture, prioritises the issues and then fixes them or hands over a clear list.
Overview
A full technical audit of how search engines actually crawl, render, and index your site — covering crawl budget, indexation gaps, Core Web Vitals, schema markup, and site architecture. This is usually the right starting point for a new engagement, because content and links cannot compensate for pages search engines cannot properly crawl or index in the first place.

How It Works
-
1
Full site crawl
We crawl the entire site the way a search engine would, checking indexation status, Core Web Vitals, and schema validity page by page.
-
2
Issues found & prioritized
Every issue — broken redirects, duplicate titles, orphaned pages, render-blocking resources — is logged and ranked by how much it is actually costing you, not just by severity in the abstract.
-
3
Fixes shipped
You get a prioritized fix list for your developers, or we implement directly if we have CMS or code access.
-
4
Clean re-crawl
A follow-up crawl confirms the fixes actually resolved the issue, not just that the code changed.
What technical SEO covers
Technical SEO is the layer that decides whether search engines can reach, render and understand your pages. It includes crawl access, indexing signals, site speed and user experience metrics, structured data and the way URLs and internal links are organised.
Content and links cannot compensate for pages that search engines cannot crawl or index properly, which is why technical work usually comes first on a new engagement.
The technical SEO audit: what we check
A technical SEO audit starts with a crawl of the site and a review of Search Console. We look at which pages are indexed and which are excluded and why, how robots.txt and noindex rules are applied, how canonical tags and redirects behave and how the internal link structure distributes importance.
We then check structured data for errors and measure Core Web Vitals so that speed and stability problems are tied to specific templates.
Crawl budget, indexation and log files
Crawl budget matters mainly for large sites, where search engines may not crawl every URL as often as you would like. Wasteful URLs, such as faceted filters and duplicates, use crawl capacity. Log file analysis shows which URLs search engines actually request, so decisions rest on evidence.
Fix, validate, re-crawl
The audit ends with a prioritised list: fixes that affect indexing first, then performance and then polish. After the fixes ship, a clean re-crawl confirms that the issues are gone and that nothing else broke.
Technical SEO FAQs
What does a technical SEO audit actually cover?
Crawlability and indexation status, Core Web Vitals, schema markup validity, site architecture and internal linking, redirect chains, and canonicalization — delivered as a prioritized fix list.
How is this different from on-page SEO?
On-page SEO is about content and metadata on individual pages — titles, headers, keyword mapping. Technical SEO is the underlying infrastructure that decides whether search engines can crawl, render, and index those pages at all.
Do you implement the fixes or just report them?
Either. We can hand your developers a clear, prioritized task list, or implement the changes directly if we have CMS or code access.
How long does a technical SEO audit take?
A full crawl and audit typically takes one to two weeks depending on site size, with a prioritized fix list delivered at the end rather than issues trickling in piecemeal.
Do I need this if my site already ranks reasonably well?
Often yes — technical issues tend to cap how far a site can go rather than tank it outright. Fixing crawl and indexation gaps is frequently the fastest way to unlock rankings a good backlink profile is not already achieving.
What is log file analysis and do I need it?
It is reviewing your server logs to see exactly how search engine crawlers move through your site — which pages they hit, how often, and where they waste crawl budget. It matters most for larger sites (roughly 10,000+ URLs); a small business site rarely needs it.
What is crawl budget?
It is the number of URLs a search engine is willing and able to crawl on your site in a given period. It matters mostly for large sites with many URLs.
What are Core Web Vitals?
They are Google's page experience metrics for loading, interactivity and visual stability: Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift.
What is the difference between noindex and robots.txt?
Robots.txt controls whether a crawler may fetch a URL. A noindex rule tells search engines not to include a crawlable page in results. A blocked URL can still appear if other pages link to it.
What does a canonical tag do?
It tells search engines which URL is the preferred version when several URLs show the same or very similar content. Google treats it as a strong hint, not a command.
How often should a site have a technical audit?
Once a year at minimum, and after any migration, redesign or platform change. Large or frequently changing sites benefit from ongoing monitoring.
Can technical SEO fix a ranking drop?
If the drop was caused by crawling, indexing or speed problems, yes. If it came from content quality or competition, technical fixes alone will not recover it.
