The meaning of SEO is Search Engine Optimization. In Portuguese it is known as Site Optimization, MOB, and Search Optimization. SEO is nothing more than optimizing a page (or even the entire site) to be better understood by search engines. The consequence of using SEO techniques is the best positioning of a website on a search results page. For example, when searching on Google for “Search Marketing”, the first result is this site. SEO is a practice without guarantees, that is, no company or person can guarantee that your site is first in a search, because the only one capable of this would be the search site itself as Google or Yahoo.
SEO came up with the new generation of search engines. Before it, organizing the links on a result pages was alphabetical as in web directories. In the new generation of search tools, positioning came to depend on relevance. This relevance is defined by algorithms, which are calculations that serve to define how important a page is. One of the best known search algorithms is Google PageRank.
The factors that influence the placement of pages are kept under seven keys by search engines. However, over time, it was possible to identify the best practices that are summarized in employing common sense in the creation and structuring of a website. Seo also depends on the keyword that is the term you use in a search. Depending on which words you use, different pages will be returned in different positions.
The SEO can be divided into two parts. Internal factors and external factors. The internals are related to the site. Some examples are clear urls, use of web patterns, rational page titles, and the correct use of html tags that is language used to build web pages. The outside analyzes how other sites relate to the site. Examples are amount of links pointing to the site, which sites point to the site and the content of the link pointed to. Depending on these factors, pages are scored by search engines so that it can determine the relevance of the page and which keywords are related to it. Google uses a scoring system from 0 to 10 that is PageRank.
There is also the dark side of the SEO known as the Black Hat Seo. In it, techniques that try to trick the algorithms of search engines to improve the positioning of the page as use of invisible text or to display different content to people and search engines are used. When discovered, search engines can punish sites that use these practices by diminishing the importance of the site or even deleting it from your search.
You should not confuse SEO with sponsored links, because in the second you can pay to have the guarantee of staying ahead of other results, and may stay first if you are willing to pay the price.
