I will programm some SEO tools as windows standalone software. But not BIG player tools, small useful helper.
I will not sell these tools as itself, i will offer to brand the tools with YOUR informations in the about box.
For example:
I programmed a Keyword Tracking Tool to check a keyword for a website ...
anybody can use this, you can give it away for free or for list building ...
And everyone who uses this software can see YOU Website, Affiliate Link and Information in the about box, on a start screen or ending screen ... There are many possibilities.
If anyone is interested in i will give more informations.
