Technical SEO

A real crawl. Real findings. No guessing.

Kestralia sees your site the way a crawler does — respecting robots.txt, with byte limits, timeouts and politeness rules. Then it returns every finding with the URL, the raw evidence and a specific fix.

Checks: 7 categories, 40+ finding types
Evidence: URL, HTTP status, raw JSON
Crawl safety: SSRF-safe, pinned DNS, bounded

What we do not claim

These are part of the product, not a footnote.

Crawling is not indexing; we only report what a search engine is able to see.
Core Web Vitals are reported only from field data or authorized PageSpeed results, never guessed.
Server log analysis runs only on logs you explicitly provide.
No ranking or traffic outcome is guaranteed.

Data transparency

Every finding carries evidence, a date and a confidence level. When a measurement is not possible, we show "not measured" instead of an invented number.

What does a technical SEO audit check?

Crawlability, indexability, canonicals, redirects, hreflang, structured data, response time and internal linking. Every finding comes with its URL, raw evidence and a specific fix.

How often should a site be audited?

For an active site, a full audit monthly and a light check after each release is reasonable. After a fix, a verification crawl shows whether the issue is actually gone.
