Another advantage of using Ahrefs is their “Fresh Index” “Live Index” switch that displays backlinks that Ahrefs’ crawler found. The main difference between the two is that the Live Index is updated every 15-30 minutes to show live links in your site. For Fresh Index, it is updated at a much longer timeframe, but it still displays dead links which give you the chance to reclaim or change the dead link.
Ahrefs make use of two link updates in your website - the Fresh Index and the Live Index. Fresh Index which updates at a longer time frame. It shows the dead links on your website, giving you the chance to change or reclaim the dead link. The Live Index, on the other hand, makes link updates every 15-30 minutes. This provides you with the chance to see regular link updates on your website.
