I've been trying to make money with Adsense for a long time with limited success and lots of frustration but I've recently decided to have another try and I think I'm making a bit of progress.
The biggest problem I faced was always that I didn't have a website which generated enough traffic to allow me to reliably generate revenue and I think I have finally made progress to solving this almost by accident. Another one of my hands on enterprises is the sale of pens and pen refills via my website at www.mitrax.com.au this business is quite successful in its own right but some of the guides and resources on this site are now ranking quite well in google and other search engines and as a result are attracting quite a bit of traffic.
The other thing that was holding me back was that I had problems getting adsense ads to display on my pages . I would add the code the ad would display for a few minutes and then disappear never to be seen again and I just couldn't work out why until I logged into google webmaster tools and found a message warning me about Spammy structured data for http://www.mitrax.com.au/ . After fixing the problems with rich snippets on my site I followed the instructions to submit a reconsideration request and a few weeks later I got a message indicating that my request for reconsideration had been successful. I had almost given up on displaying ads from adsense at this point but decided to give them one last try and to my surprise discovered that they are now displaying correctly.
These ads only make me a little bit of money every day at the moment but there is pretty much zero effort involved and if I concentrate on generating more traffic and get smarter about the way I display ads I am sure I can increase this amount .. I'll keep you posted as to how I go.
