There are couple of websites who claim to send several thousand fake visits to your website. I have few questions on that: 1) How to recognize and differentiate between real and any such fake visits? 2) Is this service successful in fooling Google analytics and make Google consider the fake visits to a real one? 3) What are the advantages and disadvantages of any such services? Thanks in advance for all your help!
Just stay away from these sites, there is no point in getting fake traffic to your sites. You will only waste your time on that and also the traffc does not converts.
Why do you need to have fake visitors in Google's eye? You need to see the real visitors that came to your website. Don't implement this for Google, but for you.
I can see no advantage of fake traffic. If you have a quality website or blog people will come back to your site. If you add fresh content on a regular basis you can rank high for hundreds of keywords and Google will reward you that way!
People use Fake traffic scripts like autosurf to get some ranking in the reffers list .You have to see the referrers . You can blacklist the IPs sending the fake traffic.
