Dada seems to be the only site I'm making money with google ads from even though I've just started using it.  It must be a very popular site with the search engines.  The thing is your blogs have to be very popular and come up in a high position in search engine listings.  I've done a few posts on my blog at Mailboxmoney about how to make your blogs more popular but mine still don't make a lot with the google ads on the page yet.  I think that it's good to join a site like this as you can network with other bloggers and have more of a chance of getting ad views.  But you can't just click on ads to help your friends and contacts money.  They have to be interested in the sites they visit.  And you can't get others to click your ads or write anything next to the ads like please click the ads or do a search here. Advertisers pay to put ads on the internet and depending what they pay for each click then if their ad shows on your sites or blogs and an interested viewer clicks on the ad and visits the site then you'll make a percent of what they paid, like a commission for getting interest to their sites.  Dadahave a lot of pages you can use all with google ads on them so members have a good chance of getting google advertising revenue.  I've only been using the site for a couple of weeks and already I've made over $5.  It doesn't seem like a lot but if you use your sites and make more you could be making $100's every week.  Well, it's more than I've made from my blogs where I earn a few cents every now and then and I've got more ads there, text ads, text links, search boxes and even referral products listed.  Imagine if my blogs are really popular then I could be making $1000's every month.
