Nowadays, there are more than two billion websites on the Internet. Undoubtedly, a user cannot cope with such an amount of information alone, so search engines are here to help. And many tools and algorithms, including meta tags, help websites in search results.
What are meta tags?
Meta tag is a code fragment that informs search engines about important information about the webpage. It is not shown on the page but in the source code. Meta tags are content descriptors that help search engines inform about the website's content. They also tell how to display the page for users.
Using meta tags is not necessary, but search engines like Google use them to understand additional information about the website. They can use them for ranking or displaying fragments in the search result, and sometimes they can even ignore meta tags.
