Every backlink tool will store different links. When building an index of the web, companies have to make many choices around crawling, parsing, and indexing data. While there’s going to be a lot of overlap between indexes, there’s also going to be some differences depending on each company’s decisions. In the name of transparency, we want to let people know more about Ahrefs’ link index. What is a link? Which links get indexed? Which domains get indexed? Why we can’t see all links What is a link? Links take users from one webpage to another when clicked. There are many ways to create them, with the most common method being the classic HTML <a> element with an href attribute. <a href="url">link text</a> However, it’s possible to create links with other elements, including: Onclick Button Ng-click Option/value And more… Which links get indexed? In an ideal world, anything that functions as a link would be stored. Unfortunately, we don’t live in an ideal world. Neither Ahrefs nor Google stores all types of links because it’s not an efficient process to load each page and click every link. That’s exactly what you’d have to do if you want to find all of the links that work for users. The workload like this whatsapp number list allows both the vendor and the affiliate to focus on. Clicks are the number of clicks coming to your website’s URL from organic search results. Instead, crawlers typically fetch pages, possibly render them, then extract and store various types of links. All crawlers work differently, so let’s talk about how we do things here at Ahrefs. Links we store Here are the types of links we store in our index. External links Links from one website to another created using the classic HTML <a> element with an href attribute. Internal links Links from one page on a website to another page on the same website. There are 22.21 trillion internal backlinks in our index. That’s far more extensive than our live external link count. We’re the only SEO tool where you can access this data without a custom website crawl. We use the internal link data in the URL Rating (UR) calculation, similar to how Google would use it in their PageRank calculation. If you want to see when we first and last crawled a URL, you can check the “Best by links” report in Site Explorer. There are tabs for both External and Internal Links.
