When you join new programme for earning purpose, you must check proof of earning of that site.... Also get some inforamtion about that sites from search engine also.... Hope, none of DP members join these types of programme in future........ which is waste of time.......
You just need to make content rich sites, and promote them, with good ad placement, and you should get a high ctr, and make decent money from the website, if the keywords are high paying.
