Part of Google's web crawling infrastructure (Trawler is Google's internal name for their web crawler). This model governs how Googlebot fetches and processes web pages, affecting crawl efficiency and frequency. Crawl management directly impacts how quickly new content is discovered and how often existing content is refreshed in the index.

The simhash value obtained from shingles.

simhashstring
Default: nilFull type: String.t

The simhash-v1 value. The simhash-v1 is now deprecated and new UrlVersions should only populate simhash-v2. During migration phase from using simhash-v1 to simhash-v2, it is possible that previous UrlChange only contain simhash-v1 and the next UrlChange / UrlVersion could only contain simhash-v2. In this case, we skip that interval in our changerate computation. [go/changerate-simhash-v2-migration]
