Knowing SEO and its Results

The number of links leading to a web page increases the ‘weight’ or ‘importance’ to this web page for the search engine.  This predetermined the new milestone in the SEO-activities: registration in catalogs and rankings, link exchanges, and other actions that increase the link juice to the said web page. So, the optimizer has to work competently. The work on each item from the list of internal and external parameters affects the search results. 

There are three classes of activities in search engine optimization, the boundaries of which can vary from one search engine to another. Professionals engaged exclusively "white" optimization using non-prohibited methods of search engine promotion resource. Permissible in some cases, the "gray" optimization involves the use of unwanted (one way or another on the list) optimization techniques: the use of automated link exchange or buying links from topical sites. It is not desirable since it is "black" optimization.

‘Black optimization’ does not exclude the possibility of removing the website from the database of search engine.  Among the methods of black search engine optimization methods are the use of hidden text (background color, a very small size) and the creation of doorways. Doorway pages - automatically (at least in the manual process) created a page with meaningless set of keywords in it. Doorways are used as intermediaries between the search engine site and spins. 

So, you must have understood something about SEO and the work of the optimizer. SEO-work has a number of pitfalls: spam filters, evaluating pages for spam and complicate the lives of honest Optimizer, constantly changing the algorithms of the system and issuing the results of calculation of reference resources, tough penalties and a big risk, even when using "gray" methods of optimization. Besides, no one has repealed the competitors who want to push you to the leading position.
