Online marketing professionals mentioned that creating and hosting a number of websites is the most famous spamming strategy. Sites like these seldom possess intrinsic value other than giving link popularity for the main website of the owner.
Domain spamming is done by creating keyword rich sub domains of your main website. For instance, if your website is all about SEO and your website is www.seo.com, your sub domain would carry one of your keywords. If your keyword is “seo company,” then your sub domain URL syntax would be: www.seocompany.seo.com. The purpose of this is merely to attract more web traffic and gain more link popularity. In some ways, this spamming strategy works. But I doubt if this works in Google though.
Several sites practiced this kind of technique and they were penalized for it because according to internet marketing experts, no spammers can escape from Google’s eyes. I do not totally agree with that because the search results that Google gives are not perfectly accurate because of some spammers that are able to get through its laser eyes. With this case, some times I am wondering if some of the spammers are actually people from Google who know how to crack Googlebot. Well, that is just a thought; and anyone is entitled for it.
