Unique URLs crawled in the Historic and Fresh indexes.

How's it different to the Fresh Index?

Our Fresh Index brings you the URLs we've found in the last 90 days, whereas Historic has every link we've ever found, ever. Historic is over four times larger than Fresh and gives you the power to perform a much deeper and wider industry analysis.

Years of archived data

The Historic Index contains all the data you need to spot the larger trends a site has experienced. You can see in our graph how many backlinks we're discovered for your URL since 14 Jan 2011, perfect to help you find historic link relationships, track down broken links, and discover valuable expired domains.

Over five years of backlink data is just a minute away
