You hear the word spam bandied about quite a bit in the world of search engine optimization and search engine algorithms. It is fairly obvious that spam is not a good thing and should be avoided. But what does Google really consider to be spam?
Well they will tell you and show you examples of the pages that are deemed to be so spammy that they are removed from appearing in search results.
According to Google, “Every day, millions of useless spam pages are created. We fight spam through a combination of computer algorithms and manual review.”
The spam biggies are stuffing keywords on a page, buying links from link farms and invisible text on the screen. Google fights spam in an effort to get rid of all the noise and give credence to the legitimate websites in an effort to deliver the best information to match a search query. Spammy sites get in the way of that goal.
To help illustrate the point, Google posts a real time screen shots of the most egregious spammers. According to Google, “These pages are examples of ‘pure spam.’ They appear to use aggressive spam techniques such as automatically generated gibberish, cloaking and scraping content from other websites.”
