How to do SEO ?

Published by: ZEROUATI AMINE

SEO a three letter acronym short for "search engine optimization" It is the process of getting traffic from the free and organic or natural search results on search engines.
All major search engines such as Google, Bing and Yahoo have primary search results, where web pages and other content such as videos or local listings are shown and ranked based on what the search engine considers most relevant to users. Payment isn’t involved, as it is with paid search ads.

Search engines have two functions: crawling and building an index, and providing search users with a ranked list of the websites they've determined are the most relevant. Links allow the search engines' automated robots, called "crawlers" or "spiders," to reach the many billions of interconnected documents on the web.

Once the engines find these pages, they decipher the code from them and store selected pieces in massive databases, to be recalled later when needed for a search query. To accomplish the monumental task of holding billions of pages that can be accessed in a fraction of a second, the search engine companies have constructed datacenters all over the world. These monstrous storage facilities hold thousands of machines processing large quantities of information very quickly. When a person performs a search at any of the major engines, they demand results instantaneously; even a one- or two-second delay can cause dissatisfaction, so the engines work hard to provide answers as fast as possible.

According to Google;  Deciding to hire an SEO specialist is a big decision that can dramatically improve your site and save your time and decrease your budget, but you can also risk damage to your site and reputation. Make sure to research the potential advantages as well as the damage that an irresponsible SEO can do to your site.

Many SEOs and other agencies and consultants provide useful services for website owners, including:

  1. Review of your site content or structure
  2. Technical advice on website development: for example, hosting, redirects, error pages, use of JavaScript
  3. Content development
  4. Management of online business development campaigns
  5. Keyword research
  6. SEO training
  7. Expertise in specific markets and geographies.

Keep in mind that the Google search results page includes organic search results and often paid advertisement (denoted as "Ads" or "Sponsored") as well. Advertising with Google won't have any effect on your site's presence in our search results. Google never accepts money to include or rank sites in our search results, and it costs nothing to appear in our organic search results. Free resources such as Search Console, the official Webmaster Central blog, and our discussion forum can provide you with a great deal of information about how to optimize your site for organic search.
