When I am advertising I have learned to never use Traffic exchange sites.
1. Everyone there is just trying to get enough credits so they can run their own ad. 99% of them do not care about your ad they only want the credits.
2. The majority of those traffic exchange sites require you to long into their sites to gain the credits for ads – I do not have enough time to spend logging into sites every day just to earn credits for my ads.
3. Traffic Exchange sites that cater to only “free” ads are mostly junk sites – and those you have to pay for ask way to much money for the low quality of the responses you will receive.
I have had much better responses from free safe email sites than traffic exchanges. Better yet are the responses you receive off your blog post or websites and social media.
