I want to ask that if i a advertise my site on facebook using Facebook Ads and back link in to my site that traffic will be google adsense safe? my account will not be block with facebook coming traffic??
I haven't had any problems with it yet. I can't say for sure. I think as long as they are real visitors and not spam generated Google doesn't care so much.
You shouldn't have a problem with it but honestly, from having spent money advertising on facebook before, I wouldn't waste my time. You can get better quality traffic making an ad through adsense.
I've done FB advertising and haven't had a problem. Though I will say that I'm not getting many conversions advertising through FB. I keep trying new ways - I think that Adwords is a lot better - but pricier of course.
