For more than 20 years, SEO has gone from being a set of simple tricks that took advantage of the design of algorithms to place sites on the first pages of results, to being the most important factor in the commercial success of websites.

The idea of entering a page without first going through a search site, having to forcibly enter the email address in the browser's address bar seems an archaic concept and even completely unknown to the new generations that since their first forays into the network they had a search tool at their disposal.

Thanks to those tools called search engines and their way of organizing content through their algorithms, the need arose for different internet sites to develop what we now know as SEO (Search Engine Optimization).

In its more than two decades of existence, SEO has become fundamental in online advertising strategies.

In the first instance, the elements that the search engines considered to order their results were limited to the title of the pages and the number of times that the search words of the users were repeated on the sites. This generated that many sites that did not generate content of real interest were positioned in the first places.

Despite the defects that resulted from this type of system, with this interaction an element emerged that to date continues to be the cornerstone of SEO strategies: keywords (keywords.)

Subsequently, other of the most determining elements of on-page positioning emerged that together with keywords largely determine the organic place that a site will have within search engine results, Meta tags and the use of blogs.

With the evolution of search engine algorithms, SEO strategies have also evolved. When the amount of external links that led to a page began to be considered as an off page SEO factor, the positioning managers of the sites began to distribute links throughout the network.

Currently, the number of keywords requires useful and quality content to be a positioning factor, it is not enough to distribute links that lead to a page on any site or have a blog with five entries in a year. The strategies positioning require a complete conglomeration of techniques ranging from the core of the sites themselves to other corners of the Internet.
