Seo, search engine optimization, is very useful and famous in internet marketing. There are many techniques that make boosting your site a success through different seo strategies. But despite the success of seo, there are some black practitioners who tend to see the field of search engine optimization as war, and the search engines are doing anything to beat the competition whether it is fair or foul. Those white hatters market with the other search engines as associates or partners who can help them drive links and business to their clients sites.

Cloaking happens when a website or a web page displays different content for a certain search engine spider in opposition to a human user. Cloaking is the one that delivers a version of a page to an Internet user and a different description to a search engine. You will notice a cloaked page is filled with keywords and phrases that the site wants to make them rank high.

This is done by cloaking the programs that weigh the IP address of the other party to a database of the known IP address which comes from a definite search engine spider. If there is a match in the IP address on the list, it serves a page which is particularly written for the search engines.

Cloaking has several good reasons which include increasing advertising and promotion. If you are trying to control your rankings in the different search engines, it might result to penalize your site or it might be banned.

Spamming or the keyword stuffing is a long list of keywords placed in the content and also the code on the page which makes it unreadable. Have you seen a page that repeatedly displays an ad with certain words? It is obvious that the site is trying to rank its page. This is known as keyword spamming but it is just one tip that most SEO companies are trying to do to increase page rank.

You might not notice the page may have invisible text, title tags, meta tags and comment tags. If a page repeats a certain keyword repeatedly, google might place a filter to lessen the ranking or much worse, ban the site. Keyword density can be quite tricky but following the general rule, 3% t0 12 % is the percentage to which a site can use the targeted keywords.

You will notice there are some hidden texts in SEO strategies. This happens when a text or link is invisible to the website visitor but can still be seen by the search engines. If this happens it is considered hidden. Before, people used small fonts to hide the text or they would even use the same color for the background.

This makes them able to put some links which are unseen, but has long been noticed by the search engines that is why they have come up with another strategy this time. Spammers are using the cascading style sheets in order to hide the text. Some are also using tags which are set to hide the text on the page. These strategies are considered hidden if they are left unseen but search engines have their own technique of spotting invisible links so better not do it at all.

The doorway pages are those that exclusively exist to rank well in the different search engines. You may notice some of the pages being ugly and some contain paragraphs which do not have any relation to the topic. Most of the time these doorway pages are not part of the regular navigation of the site which are called orphaned pages.

A black hat SEO can use very good software to filter or generate the doorway pages. This happens when they plug a few keywords and search the page.

You may notice some sites linking to other sites which are have no relation at all. Some sites just link to other sites which is part of their strategy. Now, you will find this truly spamming.

If you are going to put up your own website, make sure that you will avoid these things and keep SEO marketing fair and do not think of competition. The search engines are very smart and very often update their algorithms. So you must use only white hat seo techniques and avoid the black hat tricks.
