What is SEO and why do I need it?

1. What is SEO?

 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 often named after its English title, SEO (Search Engine Optimization).

Although there are miles of factors on which a search engine relies to position one page or another, it could be said that there are two basic factors: authority and relevance The authority is limited the frequency of a website. The more popular the more valuable the information it contains. This factor is the search engine takes more into account since it is based on the user's own experience. The more a content is compared, the more users have found it useful. Relevance is the relationship a page has to a given search. This is not simply that a page contains a lot of times the searched term (in the beginning it was like this) but a search engine relies on hundreds of factors on the site to determine this. SEO can be divided into two main groups: 

On-site: On-site SEO is concerned with relevance. It ensures that the web is optimized for the search engine to understand the main thing, which is its content. Within the SEO on the site we include the optimization of keywords, loading time, user experience, optimization of the code and format of the URLs. Off-site: Off-site SEO is the part of SEO work that focuses on factors external to the web page we work on. The most important factors in off-site SEO are the number and quality of links, presence on social networks, mentions in local media, brand authority and performance in search results, that is, the CTR that our results in a search engine. Surely you are thinking that all this is very good and that it is very interesting but that you are here to know why you need SEO on your website and what benefits you will get if you integrate it into your online strategy.

Once we know what SEO is, we have to differentiate whether or not we follow the search engine "recommendations". Black Hat SEO or White Hat SEO Black Hat SEO: Black hat is the attempt to improve the search engine positioning of a web page using unethical techniques or that contradict the guidelines of the search engine. Some 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 it is generally a risky strategy, without continuity in the long term and that does not add value. White Hat SEO: Consists of all those ethically correct actions that comply with the guidelines of the search engines to position a web page in the search results. Since search engines give more importance to the pages that best respond to a user search, White Hat understands the techniques that seek to make a page more relevant to search engines by adding value to its users. 2. Why is SEO important? The most important reason why SEO is necessary is because it makes your website more useful for both users and search engines.

SEO is necessary to help search engines understand what each page is about and whether or not it is useful to users.

How do search engines work? 

The operation of a search engine can be summarized in two steps: crawling and indexing. Tracking A search engine scrolls the web crawling with what are called bots. These go through all the pages through the links. Hence the importance of a good link structure. Just as any user would do when browsing the content of the Web, they go from one link to another and collect data on those web pages that they provide to their servers.

Indexing

 Once a bot has crawled a website and collected the necessary information, these pages are included in an index. There they are ordered according to their content, their authority and their relevance. Thus, when we make a query to the search engine it will be much easier to show us the results that are more related to our query.

Search engines base their indexes on hundreds of different aspects. The publication date, if they contain images, videos or animations, microformats, etc. are some of those aspects. Now they give more priority to the quality of the content.
