I find myself looking up footprints almost everyday and having to remember which spreadsheet, bookmark or word document to look in. So it was a delight to stumble upon chase the footprint – http://chasethefootprint.com/.
At first it looks like a very simple tool and hardly worth a mention but when you dig deeper you find it’s treasures.
There are common top level categories like guest blogging, directories, forums and blog commenting. But each contains sub-category of all the footprint terms you could ever imagine. You still have to use some imagination like sometimes putting keywords in quotes and negative phrases to pinpoint prospects.
When you hit return you are immediately taken to google search with the foot print filled in. After that it is a question of sifting through to find good prospects.
