i have a site that gets about 50-60 uniques a day. average for the past 2 months have been over 2k uniques a month. if i were to put adsense on my site would it benefit me much. the site i have is a personal blog/graphic resource site
50-60 uniques per day isn't a whole lot of traffic, so I doubt you'd get very many clicks. Maybe a few here and there if you blend them in well. You never know till you try though, and a few cents everyday adds up.
If you could sneak them in without making the website look spammy, I don't think it would hurt you very much. Your main goal is to get more traffic, but with what you have now adding Adsense might not hurt if you blend well (Though some might disagree and tell you to wait till traffic picks up!)
Why not. You can just add adsense to the site as long as they approve it. A site may be small now but it may grow in the future. I have adsense on my blog which does not quite attract a lot of people because I do not quite promote it but I do get several clicks which made me some money. Not terribly a lot but money is money. A few cents here and there can give you a nice bonus in some time. Just don't make earning from adsense as your main source of income and do not force anyone to do anything they would not want to do and you be fine.
With decently placed ad's I'd guess you'd be in the 0 - $2 a day range. (Although that may vary depending on the value of clicks in your niche)
