I have been using Traffic Exchanges for many years now and have had great success with them. I am now branching out to try safelists. The ones I have had great results from to date are ListSurfing and WebBizInsider. But today I upgraded to a life membership on Stefan Bergs The Lead Magnet. I have got some solid response rates as a free member and the time was right to upgrade. I will update on progress here.
Another newbie - really two are SolomaticAds and Solomatic Traffic both owned by a friend of mine. Go to http://drkelp.co.uk to get the links.
The Lead Magnet can be found here: http://theleadmagnet.com/index.php?r=drkelp
I would be interested to know what programs others have had success with.
