Crawl Frequency: Crawl frequency refers to how often a website is crawled, or searched, by a search engine's spiders. These spiders are automated tools which seek out new web pages and content. Crawl frequency therefore increases the more often a website is updated. However, crawl frequency also depends on site quality, domain authority, and the number of URL parameters.
A spider's tendency to focus on high-quality, updated pages is part of search engines' goal of reducing the ranking and overall presence of substandard websites. This means that because websites with low trust scores and limited link authority are crawled less, reducing their visibility. Because of this, it is important for websites to follow a number of basic SEO rules to ensure their pages are properly and frequently updated: this can include regularly creating and posting quality content, reducing duplicate posts, building editorial links, and using unique titles and meta tags for each page. However, crawl frequency can also be increased by monitoring a website's technical aspects, such as server performance, internal link structure and header responses. Some webmasters report that adding a sitemap can also increase crawl speeds.
