About a year and a half ago we set ourselves a goal. The goal was to create the largest, fastest-updating, highest-quality backlink database available on the market. Now that we've achieved our goal, we can't wait for you to test our new database for yourself! Do you want to know exactly how we managed to build such a database? All it took was a combination of approximately 16,722 cups of coffee with over 500 servers and 30,000 hours of work from our team of engineers and data scientists. Sounds simple, right? Check out this blog post to see how much faster we are now. A new and improved backlink database First let's talk about what's new, then we'll show you how we did it and what problems we solved.
How Semrush backlink database works Before we Venezuela Phone Number dive into what's been improved, let's go over the basics of how our backlink database works. First, we generate a URL queue that decides which pages will be sent for crawling. Then, our crawlers examine these pages. When our crawlers identify hyperlinks pointing from these pages to another page on the Internet, they save that information. Afterwards, all this data is kept in temporary storage for a period of time, before dumping it into public storage that any Semrush user can see in the tool. With our new architecture, we've virtually removed the temporary storage step, tripled the number of crawlers, and put a bunch of filters before the queue, so the whole process is much faster and more efficient.
Tail Simply put, there are too many pages to crawl on the Internet. Some need to be scanned more frequently, others don't need to be scanned at all. Therefore, we use a queue that decides in which order the URLs will be sent for crawling. A common problem with this step is crawling too many similar, irrelevant URLs, which could lead to people seeing more spam and fewer unique referring domains. What we have done? To optimize the queue, we've added filters that prioritize unique content and higher authority websites, as well as counteract link farms. As a result, the system now finds more unique content and generates fewer reports with duplicate links. Some highlights of how our system works now: To protect our queue from link farms we check if a large number of domains come from the same IP address.
