The meaning of SEO is Search Engine Optimization.
In English, it is also known as Site Optimization, MOB and Search Optimization. SEO is nothing more than optimizing a page (or even the entire website) to be better understood by search engines like Google, Bing, Amazon or Yahoo. The consequence of using SEO techniques is the best positioning of a website on a search results page (SERP). For example, imagine if you search in Google for “Inbound Marketing,” and the first result is this site. SEO is an unsecured practice, meaning no business or person can ensure that your site is ranked first in a search because the only thing that could be the search engine itself. If someone promises that, you’d better pay close attention to him. When done in the right way, it can even multiply business 10 times! It’s amazing saying 10 times, but that’s exactly how great is its potential.
SEO has come up with the new generation of search engines. Before of it, the organization of the links in result pages was alphabetical as in the web directories. In the new generation of search engines, positioning became dependent on relevance. This relevance is defined by algorithms, which are calculations that serve to define how important a page is. One of the most well-known search algorithms is Google PageRank. Once a while there are new releases which effectively change the game.
The factors that influence the placement of the pages are kept in the search engine by keywords. However, over time, it was possible to identify the best practices that are summarized in using common sense in the creation and structuring of a website. A good example of best practice is Vicenza SEO. The technique itself also depends on the keyword which is the term that you use in a search. Depending on which words you use, different pages will be returned to different positions.
SEO can be divided into two parts. Internal factors and external factors. The inmates are related to the website itself. Some examples are clear URLs, use of web standards, rational page titles and the correct use of HTML tags which is the language used to build web pages. We need to add the most famous one: text copywriting. The external part reviews how the other sites related to the site. Some of the possible examples could be the number of links pointing to the site, which sites point to the site and the content of the link pointed to. Depending on these factors, the pages are punctuated by the search sites so that it can determine the relevancy of the page and which keywords related to it. Google uses a scoring system from 0 to 10 that is PageRank.
There is also the dark side of SEO known as Black Hat SEO. It uses techniques that try to trick search engine algorithms to improve page positionings such as using invisible text or displaying different content for people and search engines. When discovered, search sites can punish sites that use these practices by decreasing the importance of the site or even excluding it from your search.
You should not confuse SEO with sponsored links because in the second case you can pay to be guaranteed to stay ahead of other results, you can stay up first if you are willing to pay the price.
