What is Meta Tags? Why and how to make it?

Today I wanna introduce you What is Meta Tag? Meta Tag's requirements?
On-Page SEO is very important to bring visitors from search engines. And if you want to get a visitor from search engine to your site, you must use the Matte tag. As a result, your blog or site will be friendly to search engines. For Meta description & Meta Keyword to use the Matte tag, there is no better HTML tag. (I think someone else might have different ideas.) Explain your tag or content in this tag about your site or content. And these tags help your site / blog get indexed properly. Although the Matte tags appear on the blog post, it still makes the search engines more important.

Meta Description: You can use this tag for maximum of 160 words for your blog or site. Should not be used more than this.

Meta Keywords: This tag is the most important. This is the visitor from the search engine on your blog / site. Most of the site's administrators / bloggers use dozens of keywords. If you use so many keywords, then search engines drop you. So use some good keywords according to your blog / site quality. This will get good results. If you want to do this, you can recieve Google.

Meta Author : This tag does not carry that much importance. However, many people want their name or site name to be meta author. So they use it. It does not cause any damage to your site / blog, but it gets very good contact near the search engine.

Meta Robot: Sometimes you want the search engine robots to refrain from doing some of your containings. Then there is noFollow and DoFollow in its tag. If you do not understand this tag then you refrain from using this tag. If you use this tag incorrectly, you can lose all the visitors of your blog / site from the search engine. Later on I will try to discuss this topic in detail.
There are some more tags besides the above matte tags! However, to bring new bloggers or inexperienced visitors or visitors from search engines, these are some of the most important tags.
So today so far.
