Updated Google Document on Indexors: How Catching works

Google has announced updating its documentation for the indexors by adding more cache information. This will help you better understand how to optimize your work for Google index. Following the new recommendations for the implementation of the correct HTTPE headings, SEO professionals and publishers can improve indexing efficiency and optimize the server resources.

"Google indexation infrastructure is supported by heuristic HTTP-cam, as defined in the HTTP-Kinging Standard, specifically through ETAG's title and IF-None-Match's request, as well as the title of Last-Modified and IF-Modified-Modi-Modified Request.

🚀 Google recommends switching on with headers such as ETAG and IF-None-Match, as well as optional Last-Modified and IF-Modified-Since to signal whether content has changed. This can help reduce unnecessary indexation and save server resources, which is a win for both publishers and Google indexes.

• 📌 Google recommends using ETAG instead of Last-Modified because ETAG is less prone to errors such as date formatting problems and provides more accurate content validation.
• 📌 Google indexors use ETAG values ​​if the HTTP response contains the ETAG and Last-Modified headline fields.
• 📌 Other HTTP-CEOing Directives are not supported.
