What is rechecked after SEO changes?
Recheck changed titles, content, links and technical signals, then compare search observations under equivalent conditions.
Method and interpretation
Review crawl access, indexing signals and whether a page meets search intent. Compare rankings only within the same query, engine, country, language and observation window, retaining numerator and denominator. Recheck technical fixes separately from actual exposure changes.
