I advertised on goclick enhance and others and recieved nothing but wasted clicks. I believe i wasted 300.00 for nothing. Anyways i also tried searchfeed and it sucked. But i found CrawlingTheNet and it is not well heard, i never heard about it until two months ago when someone told me on this forum and it's perfect. I recieved tons of traffic and made more sales, I know i could advertise on google and it will be the same but google is too expensive these days. Crawling The Net you could start advertising for 10.00 and recieve 10.00 free which totals to 20.00 of advertising. Advertising starts at 1 cent per click. Can't beat that ,anyways i encourage those ppc advertisers to try it.
Interesting enough, I was thinking the same thing. Oh well, forum posts are cheaper than paid advertising.
