I don’t know if we are the first to do this, but you couldn’t do this previously with so much data. Today we’ve launched our bulk backlink checker tool. The tool is free. No login is required for the first five backlinks. The free account gives you more, and as you increase your subscription, your limit increases into being able to get hundreds of backlink counts at the same time.
The tool does not use our full database, so the total backlinks are a little below our total known on the larger sites, but should be pretty useful when compared to each other.
One advantage of not using the full dataset is speed. These results come back FAST!
Sice Google’s public counts are worthless already and we have no idea how long Yahoo’s data will remain, we decided to release this tool free of charge so that SEOs don’t find themselves in limbo. We think it’s more useful than Site Explorer’s tool.
Other free tools that we already have include:
Historical backlink checker (shows a graph of up to five site’s backlinks over time)
Bad Neighborhood Checker (Shows which sites are all coming from the same IP number)
Anchor Text and other data is free for your own sites, but you will need to be a subscriber to analyze the competitor anchor text. Register for this free.
