We all need to use software at some point in our lives to be able to perform complicated tasks with relative ease. Computer’s need an operating system, graphic designers need Photoshop, writers need Microsoft Word, for online browsing you need FireFox etc.
The same is true in the world of internet marketing. New software sprouts up every day to make tedious and complicated tasks easy. Some do the job well, whilst some others still need improving. There are lead generators that go out and collect emails for you. There are link builders that generate back links for you. There are article submitters that give your site more exposure.
