I'm planning to build a new site that will offer free service to it's users.
My problem is that the site have to make significant profit to keep it's
service working and free.
I'm looking for the best methods to make profit with the site.
I already looked for advertising sites for my website, and found that Adify may
be the best option.
I know that my target audience will be very big so I was thinking about combining
CPM ads and other types of ads.
To increase the amount of impressions I thought to add extra things to the service
I want to offer like a form.
There is other options but publishing ads?
