Technical SEO foundation
Technical SEO foundation is the part of search work that decides whether a page can be fetched, rendered, recognised as unique and stored in a search index at all. When this layer fails, content and links cannot make the page appear, because the search engine never kept it.
Inside it
- Crawl access and robots rules
- JavaScript rendering checks
- Canonical tags and duplicate handling
- XML sitemaps and index coverage
- Core Web Vitals
Measured by The share of submitted URLs that Search Console reports as indexed, and Core Web Vitals against the "good" thresholds Google publishes on web.dev (industry benchmark: LCP 2.5 seconds or less, INP 200 milliseconds or less, CLS 0.1 or less).
