It is handy for checking which directory category to place your link in for maximum benefit or maybe you would like to check all the internal links on your website.

It overlays the links with a black box with the PageRank inside it. Some may overlap depending on the page layout.

We encourage you to only use this when necessary and NOT to press it on every page because it can make a lot of requests to Google.

We also take no responsibility for any page breakages or unsaved work through the use of this tool

Unlike all the other PageRank checkers, this one will tell you,

how much PR will be transfered to your site with a dofollow link on that page.

It is handy to see if a site would be worth your time of commenting

or requesting a backlink.

As well as that, it tells you, how many links, follow links, follow external links

and follow internal links there are on that page.

It also uses a random Google server to fetch the PageRank value to stop you

being throttled by Google
