Do you know about statistical websites that are also known as Who-IS websites? I came to know that there are more than 70,000 such sites and we can submit our sites to them to increase backlinks. In my 10 years of Internet marketing, I have not come across submitting to statistical websites. Thanks for your insights.
Yes - I recently heard about this. On one hand I think the backlinks are unlikely to have much of an impact, but its so easy to do it seems silly not to do it. Does anyone have a list they want to share?
These sites might help for indexing but won't do much in a competitive niche. Sometimes you can't even use your anchor text and some are NoFollow which makes them almost completely useless.
A few persons are offering to submit your site to a huge number of statistical websites for a small fee in a freelancers' marketplace. As 'zexy' said, statistical websites can only help in indexing a site.
