How are Backlinks Updated?
We constantly crawl the web to find new backlinks and update the backlinks data in the interface within 15 minutes from the time we find any changes. Our Backlinks Analytics database is updated to show you the backlinks that our bot saw in the last 6 months of crawling the Internet. We call this “Fresh index.”
All the backlinks data that we have gathered was from our own sources and not through third parties, making our database as accurate as possible. Daily, our bot crawls over 25 billion links, the database itself is updated within every hour. According to this study, Semrush is the fastest at backlink discovery, compared to other tools on the market.
For benchmarking against competitors, you can use Authority Score – our compound metric that measures the impact of a webpage or domain’s links. It is based on actual traffic data and provides clear indications and assessments, which are hard to manipulate.
If you run a Backlink Audit campaign, we will gather your initial set of links from our Backlink Analytics reports, going back 3 months from the start of your campaign. However, the "Lost" links from the Lost and Found tab represent links that have been lost over the past 2 months.
You can re-run your campaign at any moment (1) or schedule an automatic recrawl from the settings menu of the tool (2, 3).
If you’re analyzing a large domain, Backlink Audit commonly will show a lower number of backlinks than Backlinks Analytics does. You can read more about it in this article: Why does the Backlink Analytics report show more backlinks than Backlink Audit?
