Search Robot / Crawler – SEO WIKI
The search robot is a content crawler for entering into a common database. Crawler crawls the site using the navigation system. Due to the limits of search services on the volume of crawled text and the depth of penetration, indexing may be incomplete.
The main principle of the search robot is to go to the next pages using the links found on the previous ones. Thoughtful linking, a reasonable limitation of the level of nesting and the optimal amount of textual information contribute to improved scanning.
To speed up the indexing process and find out how a search robot sees a site, you can turn to specialized services in the Google Search Console or Yandex.Webmaster. Limit content crawl with robots.txt.
