Technical SEO FAQ · XML Sitemaps & Robots.txt

How would you safely change robots.txt on a high-traffic production website?

Treat robots.txt as production-critical configuration.

Before deployment:

  1. export current file;
  2. identify affected paths;
  3. test rules against representative URLs;
  4. confirm important resources remain accessible;
  5. validate staging behavior;
  6. deploy;
  7. immediately test critical URLs;
  8. monitor crawl/indexing data.

A single wildcard can affect millions of URLs.
