I found this tool and it works really good for checking all my websites' PageRank. http://www.thedesignfoundryonline.com/ Download for Windows or Linux Here is what their website says: INDEXA is the only FREE BackLink, PageRank and Indexed Pages Checker available. INDEXA can check hundreds of URL's at a time. This application will save you a fortune in time & money. Use it to: analyze your URL, your competitors URL, domain names being sold on the web, identify fake page ranks and worthless links. You can even analyze expired domains on mass!
Has anyone tried the INDEXA tool yet? I have been regularly checking my domains with INDEXA and some of my sites PageRanks are changing, so I think it must be fairly accurate to the other tools. I don't like the fact that the INDEXA tool cuts off the ends of several domain names in the column. It's not a big problem -- you can figure out what the domain is. Also I don't believe their estimated value of the websites.
it looks an intreting tool but what are difference between the other tools? what does your tool offer?
I tested the tools, it's not that accurate while it's fast but it's need registration to get a fully working version while it's free but what to expect from a free tool.
What I like about this tool is I can quickly check my 70+ domains at once. They keep improving the tool so maybe it will get better.
