Professor is right. I’ve tried Xuppa and saw no results. ePilot was AWFUL–no results with them either. I saw 1 download and 1 player from 550 clicks on Kanoodle. And they have the gall to give me a bunch of nonsense about my site not meeting their editorial guidelines for the keyword phrase “casino bonuses”. Breathtaking in its stupidity.
I have seen some results from GoClick and FindWhat.
A good use of your money might be to find a reputable source of information regarding search engine optimization. That’s my plan right now anyway.
