Technical SEO that search engines can actually read
You can write great content and still be invisible if search engines can't crawl, understand or trust your site. I handle the technical layer of SEO — the structure, indexing, structured data and speed that decide whether your pages get a fair chance to rank at all. It's the same work I did building an SEO-oriented site structure for a data company.
- Crawlability and indexing issues found and fixed
- Clean site structure, internal linking and URL architecture
- Structured data (schema), hreflang and metadata done right
- Core Web Vitals and performance as ranking factors
/ Fit
Who this is for
- Business sites that publish content but don't rank for it
- Multilingual sites with hreflang and duplicate-content problems
- Stores and sites failing Core Web Vitals in Search Console
- Anyone who suspects the problem is technical, not the content
/ The work
What technical SEO includes
Technical audit
I check crawlability, indexing, structure, structured data, speed and mobile, and report what's actually holding rankings back.
Crawl & index fixes
Robots, sitemaps, canonicals, redirects and status codes cleaned up so the right pages get indexed.
Site structure & internal links
A logical architecture and linking that spreads authority to the pages that matter.
Structured data & metadata
Schema, hreflang, titles and descriptions implemented correctly for rich, multilingual results.
Core Web Vitals
Performance treated as the ranking factor it is, measured before and after.
Answer Engine Optimization
Structuring content for AI answers, voice search and featured snippets, covered in more depth on the AEO page.

AI and agent-readiness
Technical SEO is now also the base layer for AI visibility. If your site has poor crawlability, weak schema, hidden content, broken internal links or slow pages, AI search systems and agents inherit the same problems classic search engines do. For businesses that care about ChatGPT, Perplexity, AI Overviews or agentic commerce, I connect technical SEO with Generative Engine Optimization: structure first, content second, monitoring after.

Frequently asked questions
Who is Technical SEO for?
Technical SEO is for founders, small businesses and teams that need hands-on work on a website or web product, not just high-level recommendations.
How does the engagement start?
We start with a short description of your goal, current state and constraints. I then suggest the scope, priorities, next steps and a realistic delivery model.
Do you implement recommendations in code?
Yes. I work as a developer, so I can not only prepare a plan but also implement changes in code, site structure, integrations and configuration.
