Resilient sites for Google's updates.

  • Crawling and indexing: robots.txt, sitemaps, canonicals, hreflang.
  • Semantic HTML and JSON-LD structured data faithful to visible content.
  • Speed: LCP ≤ 2.5 s, INP ≤ 200 ms, CLS ≤ 0.1 at the 75th percentile.
  • Migrations with 301 redirects.

For the diagnosis first: technical audit.
