Technical SEO for websites
Technical SEO checks a page’s path from discovery to correct rendering and is not reduced to one metric. Technical optimisation removes barriers to crawling, indexing, and rendering across every page type.
Crawling and URL map
We build a map of accessible URLs, response codes, internal links, and repeated templates. The goal is not a report with thousands of lines, but an understanding of the path from key sections to important pages and of breaks, loops, or unintended URL variants.
Rendering and content access
A page can look complete in a browser while exposing an incomplete semantic framework before interface scenarios run. We check where headings, main copy, links, and error states appear, and whether interface logic obstructs access to material.
Migrations and URL changes
When structure changes, we map old and new URLs, check 301s, canonicals, and internal navigation. After release, we monitor key sections, errors, and unexpected chains: migration does not end when redirects are enabled.
What the work includes
Technical SEO covers everything that affects how search engines discover, process, and render a page. The list is refined after the crawl: a catalogue and a service site have different risk points.
- Site crawl and URL map: response codes, redirects, chains, and duplicate addresses.
- Configuration of robots.txt, the XML sitemap, canonical links, and indexing directives.
- Rendering review: availability of headings, copy, and links in source and rendered HTML.
- Speed and Core Web Vitals analysis by page type with causes and priorities.
- Mobile version, responsiveness, and viewport checks on real devices.
- HTTPS, mirrors, a single site address, and server error handling.
- Review of pagination, filters, sorting, and parameters that generate extra URLs.
- Migration preparation: URL mapping, 301 redirects, and post-release monitoring.
What we need from you
Technical SEO requires observation data access and contact with whoever makes server and code changes. The more precisely the deployment process is described, the fewer changes are lost at the next release.
- Access to Yandex Webmaster and Google Search Console to check crawling and indexing.
- Information on hosting, CDN, caching, and how changes are deployed.
- Contact details for the developer or server administrator who implements fixes.
- Access to a staging environment, if one exists.
- Plans for upcoming site changes: redesign, migration, CMS change.
- Access to server logs or crawl reports, if the host provides them.
What you get
You receive a technical SEO audit with a URL map, a defect list, and correction requirements written for a developer: what to change, where, and how to verify. Robots.txt, sitemap, and redirect settings are implemented on agreement; code changes are handed over as tasks. After release we verify every item and deliver a report.
Documents
A technical SEO audit with a URL map, a defect list by page type, and correction requirements written as developer tasks with an expected result. The document is written for a developer and needs no SEO background to read.
Implemented changes
Robots.txt, sitemap, canonical, and redirect settings made on agreement, plus code changes where we carry them out on a staging environment. Every change comes with a note on what changed and why, so it can be rolled back.
Verification report
A check of every item after release: response codes, markup, speed, Webmaster and Search Console reports. For migrations, monitoring of critical sections and redirect chains. Open items stay in the report with a reason and an owner.
How the work is organised
-
Step 1
We gather details on the platform, server, caching, environments, and planned changes that may affect priorities.
-
Step 2
We crawl the site, build a URL map, and check rendering, speed, and the mobile version by page type.
-
Step 3
We prepare a defect list with priorities, expected behaviour, and correction requirements a developer can act on.
-
Step 4
We implement settings and hand tasks to the developer, verifying each one on staging before release.
-
Step 5
After release we check published pages and Webmaster and Search Console reports and record what remains open.
Scope and estimate
The scope of technical SEO depends on site size and template count, rendering and interface complexity, the state of the server and caching, and whether a migration or structural change is planned. Implementation is considered separately: diagnosis and code changes are estimated differently. The task list is fixed after the crawl. Sites with a JavaScript-framework interface and sites ahead of a migration need more time for rendering checks and URL mapping.
Frequently asked questions
Will Lighthouse improvement alone help?
No. Performance scoring does not reveal every crawling, indexing, URL, or structural issue. A metric improvement matters when it improves access to important content.
How are JavaScript pages checked?
We compare source and rendered output, headings, copy, links, and error states. Findings are tied to a specific template and published URL.
How long does technical optimisation take?
It depends on site size, template count, and how quickly the developer implements fixes. Diagnosis is faster than implementation because some tasks need code changes and testing. The work sequence is agreed after the crawl. Tasks that block others are moved to the front so the developer is not left waiting.
How does technical SEO differ from an SEO audit?
A technical SEO audit is the part of a full SEO audit that covers crawling, indexing, rendering, and speed. A full audit additionally reviews content, structure, and commercial factors. Technical SEO as a service includes not only diagnosis but also implementation of fixes. If you only need a diagnostic document, that is the separate SEO audit service.
Is a developer needed?
Almost always. Some settings are made in the CMS, but rendering, speed, server-level redirects, and parameter handling require code or configuration changes. We write tasks so the developer understands what to change and why. If you have no developer of your own, we can make the changes within an agreed scope.
How is the result verified?
For every defect we record the URL, expected behaviour, and verification method. After release we check response codes, markup, speed, and indexing reports; for migrations we also monitor critical sections and redirect chains. The control sample is kept so the check can be repeated after future releases.
