Spamming the Search Engines
Links offers/demands

This is a list of the most popular offenders:
 

● Doorway pages.

Doorway pages are pages designed to rank well in specific search engines for specific key-phases and to be found many times over in their search results.  Hundreds, sometimes even thousands of them are created and submitted for the "benefit" of just one website with the purpose of getting listed a multiple of  times in the target search engines. These pages usually have no useful content and all are copied many times over from just one page.

● Page redirects.

Page redirects are pages designed only for the search engines. These pages use meta refresh tags that send the web surfer to another page without his intervention.

● Link farms.

● Over submitting.

Over submitting is sending more pages than a search engine allows within a specified limit of time.

● E-mail spamming.

E-mail spamming means sending unwanted commercial messages, specially of gambling and pornography.

● Code swapping.

Code swapping involves the optimizing of a page for a high search engine position and them swapping another page in its place as soon as it gets a top ranking.

● Keyword stuffing.

Keyword stuffing are the repetition of keywords in invisible text and in very small letters, usually at the end of the web page. Fonts are made to look "invisible" by making them as the same color as the background where they are located. Very small fonts might not be very visible to the naked eye but are as visible as the rest of the letters in the website to the search engines spiders.

● Invisible keywords/key-phrases in the content of the page.

Since the same keywords/key-phrases that are in the html of the page must be in the content of the page in order to correctly optimize it, some SEO's use a technique that is not accepted by the mayor search engines. In order to shorten the time involved in optimizing a page they use a technique that involves writing keywords or key-phrases with the same color or even very similar as the background in order to hide them. In some cases the font used is the smallest the SEO can grab or the same color as the background or both. People can not usually see them but the search engines can. A new problem an SEO can encounter using these tried techniques by spammers is the fact that now some search engines crawlers are analyzing where the keywords/key-phrases are located. Too many of these in one area, invisible or not will carry a penalty with them.

● Cloaking.

Cloaking is a technique to show search engines pages that the web surfer do not get to see. In some cases cloaking is used with the sole purpose of making the search engine crawlers believe that a site have thousands of pages when in fact they have just a few, in order to gain in link popularity and obtain high positions in the search engines.
