SEO SEO SEO. Who came up with this word? I entered into the search google.ru request - seo and a good wick tells us that this process is called as - search engine optimization
Search engine optimization (SEO search engine) - the process of adjusting HTML code, text content (content), site structure, controlling external factors to meet the requirements of the search engine algorithm, in order to raise the site position in search results in search engines user requests. The higher the position of the site in the search results, the more interested visitors will go to it from search engines.
As Vika writes, this is an integrated approach to your site so that it meets certain standards, for some reason this is great, all sites will have a standard, the search will show the site when it stores the actual information that the visitor is looking for. to the search engine site for example google.ru, yandex.ru.
/ me recently began to enrage when seo began to assign a bunch of stupid shit sites of so-called “mirrors” that have up-to-date information, but mention their parent in every “n” word, which affects the output of relevant information in search engines .
')
Let us give an example (as an example, the material received from my friend was used as a result of his search for torture to obtain information.):
I want to find say on yandex.ru material - gym, tips on nutrition
As a result of the search we look:

In general, the result can be noted that the first 10 sites of the result showed us what you need to look for money and go to spend on coaches to achieve something. That is, Yandex responded - I DIDN'T FIND ANYTHING, LOOKING FOR AT LEAST THERE'S GOODS.
Great, looked. The main market leaders are yandex.ru, google.com. Well, then you need to look at what google.ru says about this, we look:

I paid attention to the fact that Google in the top three already shows us sites that actually contain material. I opened all three sites and saw the tips, of which the site number 2 and 3 contain a large article with material that contains the tips we need, and where you can do without material costs.
Firstly, this variation is related to the search engine policy, but what happens is that Yandex is trying to advertise its system members, and Google is providing material. This is +1 additional voice of Google, for what it focuses on the visitor of his own, and not on the participant, he is not trying to deceive and force us to visit the site.
Secondly, in addition to the policy, good moderators and administrators of their sites, they lack what they do according to the standards, the site complies with all the rules, design, they start to make mirrors, to hang everywhere where you can only links that affect the results of search engines. That is, moderators, administrators, by deception, raise their site higher, in order to surpass their competitors.
As a result, certain search engines provide information relevant to our request, and some (yandex) show only one commercial advertisement, thus the project shows that the search is needed not to search, but to provide advertising to the system’s participants, and this is not there is right, because the visitor does not need it. Yandex forgets that the visitor needs and he puts his opinion on the first place ... 30 advertising sites, and then possibly the necessary information.
