for now i barely have any traffic cause i just opened the blog but i think for the future if it will have good traffic.
how much did you get for a month? it seems like you already withdrawed big part of the money so i can't realy know how much you earned that month or how much did you earned from the clicks.
i just looked in their site and saw in "websites" a table of websites with traffic and the "BTC per day", it is what they earn per day or what the advertiser is paying and only small fraction of it going for the publisher?. and why allmost everyone of them is bitcoin related site? does it have any effect if the site/blog with the ads is not about bitcoin?.
In answer to your first question...
https://a-ads.com/ad_units/6558/statsI've just recently started advertising my site again, so much more traffic...
For adbit.co, that's what is bid per day... Almost all of them are bitcoin related, well because it's bitcoin advertising service..
I would advertise on a non-bitcoin site though, fresh customers.. I do notice though if you aren't on the first 4 pages on the adbit.co site,
you don't get the good paying bids... But if you can get on the first page
