Please post your reviews of any known PPC/CPC/CPV/CPI/CPM advertising network sites. This thread is for reviews of advertising services not publishing. Personal experiences based on ad spends and campaigns that have received traffic generating either positive or negative results are appropriate comments for this topic. This is a place to share your success or failures of marketing through paid advertising.
I have had personal experience with $100 ad spends on 7Search, AdMarketPlace, Affinity, and Advertise.com and some testing spends with Linkbucks, Adf.ly, and Popads.net primarily driving traffic for the purpose of producing Click-thrus and CPA/CPS conversions. Based on these experiences I have found that both Affinity and Advertise.com appear to be primarily creating and charging for visits by the use of Malware/Spyware that utilize Internet browser re-direct exploits. 7Search appeared to generate traffic from publisher sites that consisted of little content that were producing high amounts of traffic from 3rd party sources of unknown origins. I suspect Admarketplace of using browser re-direct traffic based on previous comments throughout the web about a virus related to their network. In addition - low or no conversion or click thrus were realized by linkbuck, adf.ly, or popads.net. Your comments and suggestions about ad networks that have high performance - quality traffic will be a valuable resources to support these networks and fellow Internet marketers.
If you are going with adword, make sure you are loaded. Otherwise you are just pouring water out of the window. I usually spilt test an ad on adshorty.com until I get a reasonable conversion ~2-3%. Until then, would I consider adword.
