u can make money with 5 visits a day if the ads appeal to them, its not always "the more traffic you get, the more money you make" - cuz i've seen sites that get a few hundred impressions make much more than ones that get few thousand a day :/ but i agree - more traffic gives you more of an opportunity to make more money
most of the people now about ads so they dont click think that its spam so integrating the ads will results into more clicks and high paying keyword will give more money
I have one site which receives 140 uniques per day and earns me $13/day average. I have another site which receives 3,000 uniques and earns me the same. It's all relative, the niche and ad placement.
The is a guy who gets 40 unique visitors a day and makes 60 pounds (~$120) -General rule is "more traffic" because of the numbers game -ratio- (you can control this-doorways-purchasing traffic...). -High paying keywords also play a role-but Google de-value those common ones on some sites (you have less control over this). -Ad placement/your site template/content dictate CTR- (you can control this). Therefore any amount of traffic can do if you play with the above factors.
100 unique visitors a day and 5% click your ads = 5 pers. click ads x ( if you coose web hosting you can earn $3/click) = $15/day $450/month $5400/year
That basically sums it up...it's different for every niche. *hint* Niche where people are looking to solve their problems/issue has a higher CTR
I get 100-150 unique hits a day and dont make jack. I guess its all about placement like everyone said, and blending the ads in with the content.
