Each page has its own hash code which helps us prioritize crawling
Come from the same IP address. If we see too many domains from the same IP, their priority in the queue is lowered, allowing us to explore more domains from different IPs and not get stuck on a link farm. To protect sites and avoid spamming our reports with similar links, we check if there are too many URLs from the same domain. If we see too many URLs on the same domain, they are not all crawled on the same day. To ensure we crawl fresh pages as soon as possible, URLs we haven't crawled before are given higher priority.We take into account how often new links Cambodia WhatsApp Number Data are generated on the source page. We take into account the authority score of a web page and a domain. Queue Improvement Technique More than 10 different factors to filter unnecessary links. More unique and quality pages thanks to new quality control algorithms. Crawlers Our crawlers follow internal and external links across the Internet looking for new pages with links. So, we can only find a page if there is an inbound link to it. Looking at our old system, we found that it was possible to increase the overall crawl capacity and find better content - content that website owners would want us to crawl and index.

So what have we done? We have tripled the number of crawlers (from 10 to 30). We've stopped crawling pages with URL parameters that don't affect page content (&sessionid, UTM, etc.). We've increased the frequency of reading robots.txt files on websites and following the guidelines they contain. Crawler Improvement Technique More crawlers (30 now!). Clean data without garbage or duplicate links. Better ability to find the most relevant content. Crawling speed of 25 billion pages per day.
