I was considering to add adsense on a free-host.url/my-username, but i wonder if google will ban me if another user abuses using the same hosting. thanks
You mean like freewebs.com/joebloggs? They'll know that it's a free host and your only responsible for your particular subdirectory. Google might ban you if another user abuses your ads wherever they are. A lot of people start off using free hosts like Blogger without any problems - however, I would avoid writing anything which could attract adverse attention.
I agree. Many people have sites hosted by blogger or free host and make a little extra money. Most sites will not be ranked high enough to make any real money. Google likes paid domain names and if it is paid for more than a few years. The more years the better. As far as someone clicking links and getting you banned everyone is in that boat no one is safe. If google thinks site abuses clicks any site can get banned. Go for it why not maybe make few bucks but do not spam site or spam keywords.
This is interesting, can you explain a bit more? Domains with registrations paid for +1 year have advantage over domains with year by year renewals?
mate one thing is very much clear, you can use google adsense but with glass care. dont spam the things here and ther and get ban after wards . so take care of some things u will b earning good income.
