Where the term SEO (Search Engine Optimization) arise?

The first search engines emerged in the early 90s and until Google appeared in 1996 many, including Yahoo were created; that's when he started the boom of web pages and people realized you could really make money with them. It was then obvious way they concluded that they needed to attract traffic and what was the best way to attract traffic ?, effectively search engines. Just then the owners of the sites began to think how they could reach the top positions ... SEO was born!
SEO focuses on organic search results, ie, which they are not paid:
organic results
But hey, let's go to what matters and why (I think) you are reading this chapter:

1. What is SEO?

According to Wikipedia, SEO is:
Search engine optimization or search engine optimization is the process of improving the visibility of a website in the organic results of different search engines. It is also common to name it by its English title, SEO (Search Engine Optimization).
SEO is one of the "disciplines" that has changed in recent years, we have only to look at the large number of updates that have been of Penguin and Panda , and how they have taken a 180 degree turn to what is He meant by SEO until recently. Now with the SEO it pursues what Matt Cutts himself calls "Search Experience Optimization" or what is the same, all for the user.
Although there are many factors that a search engine is based to position a page or another one could say that there are two basic factors: the authority and relevance
  • The Authority is basically the popularity of a website, the more popular a page or a web is valuable information it contains. This factor is what a search engine takes more account since it is based on the experience of the user, the more content is that more users have found it useful to them is shared.
  • Relevance is the relationship you have a page in front of a given search, this is not simply a page containing a lot of times the search term (in the beginning it was so) if a search engine is based on hundreds of factors on-site to determine this.
In turn, the SEO can be divided into two groups: the SEO on-site and off-site SEO.
  • On-site : The on-site SEO is concerned with relevance, ensuring that the site is optimized for the search engine understand the main thing, which is the content of it.Within the SEO On-site we would include optimizing keywords, charging time, user experience, code optimization and format of the URLs.
  • Off-site : The off-site SEO is the part of SEO work focuses on external to the website we work factors. The most important factors in SEO off-site are the number and quality of links, social media presence, mentions in local media authority of the brand and performance in search results, ie, the CTR having our results in a search engine.You're probably thinking that this is all very well and that is very interesting but you are here because you need to know the SEO on your website and you will benefit if you integrate your online strategy.
SEO can make a difference in whether or not to follow the "recommendations" of the search engine: Black Hat SEO and White Hat SEO
  • Black Hat SEO : It's called black hat to attempt to improve search engine rankings of a website using unethical or contradicts the guidelines of the search engine techniques. Examples of Black Hat SEO are Cloaking, Spinning, SPAM in forums and blog comments, or Keyword Stuffing. The black hat can provide benefits in the short term, but is usually a risky strategy, without continuity in the long term and does not provide value.
  • White Hat SEO : Consists of all those ethically correct actions that meet the guidelines of the search engines to position a web page and search results. Since search engines give higher priority to pages that are more responsive to a user's search, comprising the White Hat techniques that seek to make a page more relevant for search engines by providing value to its users.

2. Why is SEO important?

The most important reason that SEO is necessary is that makes your website more useful to both users and search engines,  although the latter are increasingly more sophisticated, yet can not see a website as does a human. the SEO is needed to help the search engines to understand about what each page and whether or not it is useful to users.
Now let's put an example to see things clearer:
We have an e-commerce dedicated to the sale of children's books, well, for the term "coloring" there are 673,000 monthly searches, assuming that the first result that appears after you do a search on Google gets 22% of clicks (CTR = 22%), we would getaround 148,000 visits per month.
But how much are these 148,000 visits? Well, if that term average spending per click is 0.20 € we are talking about more than 29,000 € per month. This just in Spain, if we have a business-oriented several countries, hourly 1.4 billion searches are conducted in the world, of those searches, 70% of clicks are on the organic results and 75% of users They do not reach the second page; if we consider all this, we see that many clicks per month for the first result.
SEO is the best way for your users to find you through search on your site is relevant, these users are looking for what you offer them and the best way to reach them is through a search engine.

3. How do search engines work?

Running a search engine can be summarized in two steps: crawling and indexing .


A search engine runs the web tracking with what are called bots these bots walking all pages through links (hence the importance of a good link structure) just as you would any user to navigate the content the web, moving from one link to another and collect data on these websites that provide their servers. the tracking process begins with a list of web addresses from past crawls and sitemaps provided by other websites. once access these web, bots seek links to other pages to visit them. The bots are particularly attracted by new sites and changes to existing web.
Are the bots themselves decide which pages to visit, how often and how long they will track the web, so it is important to have an optimal load time and updated content.
It is very common in a web page you need to restrict crawling certain pages or content to prevent these from appearing in search results. For this, you can tell the bots of search engines do not crawl certain pages through the file "robots.txt".


Once a bot has tracked a website and has collected the necessary information, you pages are included in an index where they are sorted according to their content, their authority and relevance ; so when we make a query to the search engine will find it much easier to show the results that are more related to our inquiry.
At first search engines they were based on the number of times a word is repeated on a page, to do a search in its index tracked those terms to find what pages were in their texts, better positioning the most capped what had repeated. Currently, search engines are more sophisticated, and base their rates on hundreds of different aspects such as the date of publication, if they contain pictures, videos or animations, microforms, etc.Now give more priority to the quality of content.
Once the pages are crawled and indexed, there comes a time in which it operates the algorithm  algorithms are computationally deciding which pages appear earlier or later in the search results. After the search, within milliseconds, the algorithms are able to search the indexes and know what the most relevant pages considering the hundreds of ranking factors are.
