Hi I have heard that if someone comes from a website like Digg.com, Delicious.com and others like these then clicks on an ad on your web page, you will not earn money. Is this true?
Its just like any other social networking site, if your ads look attractive people will click on them thus you can make more money but the hardest thing is to get them there in the first place.
This is not true....I have a good amount of visits on my blog from stumble upon, digg, yahoo buzz, rambhai, indianbytes.....and earn me a decent $$$$.... So there is nothing true in that u can earn if visitors from above social bookmarking sites visits u'r site/blog and click on Ads..
Most of the people who make a living from adsense, don't try and get visitors from the social networks - because they have a reputation of not buying anything, or performing a "desired action" of giving their email address, or whatever If the majority of visitors you are sending to the adwords advertisers sites are not buying or performing the desired action, you as an adsense publisher will be "smart priced" - i.e. your adsense clicks will then only be for a few cents per click, regardless of how much the adwords bid prices are
I suppose it would be possible for Google to block payments if they went threw curtain sites, but there is no logic to it. You usually get to a site from a site, and even if its threw advertising would it be fair to say "you don't get paid if its a result of advertising". Thats how the world goes around
