I am just interested, how much such a site can earn per month, how do you think, maybe you can use some tools to estimate?
Your question is too vague my friend. You have not specified what type of site you are interested in making, or in what niche and basically no-one can predict whether or not a site will make money. It has been said that you could be selling $100 notes for $1 online but if no-one knows where your site is you won't make any sales. If you can expand on what you are asking a bit more, I will try and help. best wishes lisa
OOoops my apologies you did give a site link in your question - I clicked on the site and a couple of downloads but I can't see what ways the site is actually making money - is it through advertising, or page impressions, CPA???
