I am starting with www . GoArticles . com just because I saw it once, and because the site looks nice and professionally done (not discussing the content here, just look-n-feel).
Chose a random article. Saw immediately that the article is a "paid advertisement" done by a freelance writer. Short text with three links having a specific phrase.
The links go to "www . [SomeSite] . com"
Let's see if those links are recognized by search engines, and what other links point to the same site.
I will use Yahoo this time and not Google. Google is a "funny beast" when it comes to the links. It shows some of the links. I'll come to that later. For now - let's go to Yahoo and search for
link:http://www . [SomeSite] . com -site:www . [SomeSite] . com
Received 15 thousand links!!! I doubt they all were done manually...
I am going to write down all the URLs from the first N pages and try to analyze them.
To be continued...
