SEO (Search Engine Optimization) is the optimization of the exiting code (HTML), the content and structure of the website, in order for the search engines in internet to better index it and thus show it on leading positions in their search results. For this purpose, a set of rules need to be followed in designing and maintaining the website.
Search engines are websites, through which the internet users can search for specific content.
Search engines have two main mechanisms:
- Visiting mechanism, which periodically visits the pages of all websites present in internet and analyzes them
- Searching mechanism, which searches for keywords defined by the user and presents a list of websites, the content of which corresponds to the requirements. The search results are based on the information gathered and stored by the vising mechanisms.
One of the most efficient ways to popularize a website is through its listing by search engines.
