[Search engine optimization and Online marketing] Defining Black Hat SEO: ·         Keyword stuffing: Keyword stuffing is the art of placing keywords in the pages. Don’t do it. There is a correct way of placing keywords on the webpage such as: embedding keywords in the title tag, meta tags and in the image alt tags.

  Even CNN Keyword Stuff and "Blog Spam": I wouldn't jump to any concusions. CNN is an authority site with about 10Mil backlinks in Y. They have no problems ranking for MANY keywords and phrases and obtaining a dozen of new backlinks (or even 50000) is not going to make much difference to them. Just because something appeared on 10 websites does not mean anything and can be easily accomplished by one person not related to CNN at all.

seo and affiliate marketing blog: A short while ago, Threadwatch member Adam_C discovered what for all appearances seems to be Google pulling dirty SEO tactics on it’s own pages and thus going against it’s own guidelines in an effort to rank highly within it’s own results.
