Show you how we introduced them and what problems we solved. With increased storage space and three times more crawlers, our backlink database now has the capacity to find, index and grow even more. On average, we now explore: 3Te3 How the Semrush Backlinks Database Works Before seeing in detail what has been improved, let's review the basic principles of how our backlink database works. First, we generate a URL queue that decides which pages will be crawled. Then our crawlers go to the Internet and inspect these pages.

Once our web crawlers identify hyperlinks that Cambodia WhatsApp Number Data point from these pages to another page on the Internet, they record this information. Then there is a temporary storage that keeps all this data for a while before dumping it into the public storage that any Semrush user can see in the tool. With our new version, we've virtually removed the temporary storage step, added three times more crawlers, and added a set of pre-queue filters, so the whole process is much faster and efficient. img-semblog Queue To put it simply,  Some need to be explored more often, others not at all. Therefore, we use a queue which decides the order in which URLs will be crawled.



A common problem with this step is crawling too many similar, irrelevant URLs, which can lead to people seeing more spam and fewer unique referring domains. So what have we done? To optimize the queue, we've added filters that prioritize unique content, higher authority sites, and protection against link farms. So the system now finds more unique content and generates fewer reports with duplicate links. Here are some examples of how it currently works: To protect our queue from link farms, we check if a large number of domains.
