Can someone tell me what is an average income per click with this niche. It it around 0.01$, 0.10$ or 0.50$ (i really doubt that's 1$) Im already building site so im curious is it smart to add google adsense or some other income source. Thanks!
The only way to really know is to try it. Just keep in mind that your first week or so of clicks will probably be high, then level-out as smart-pricing kicks in. Let us know after you try it!
There is no set cost per click rate, it varies from day to day. You can try using this Adwords keyword tool to help you get a general idea of what advertisers are paying for certain keywords though. https://adwords.google.com/select/KeywordToolExternal
At the beginning you could get $0.10 - $0.20 per click. But after smarpricing that prices could drop to $0.02 - $0.06 aprox.
