Basic HTML Meta Tags and various others have been around since the invention of HTML, basically, but in the modern age are they relevant any more? Here are some rather useful ones.

Ever since the first lines of code where written on a piece of paper or in a notepad editor, there has been meta tags that either were needed or invented by a service to discover, verify or authenticate the page.

In the beginning it was basically just a few that were needed and it progressively became a way for companies like Google, Yahoo, Bing, Apple and others as well as institutions to scrape data of pages using meta tags.

There wasn't really a standard, it was everyone demanding from the user to add a company specific meta tag in order to be included in a search engine or to get and stay verified. But, the question is, was it really necessary?

Surely there could have been a way that the giants of the industry could have verified the existence in a better way then through a meta tag, right?

Today, we are more or less given a choice if we are to add a meta tag or simply upload a file to the server in order to get our webpage included in a search engine. Many choose the file since then you are not crowding the header with a ton of meta tags for verifications and discoveries for search engines.

Below are some amazing meta tags that still are rather useful. Do note that some of them needs you to have additional files or feeds in various formats, so grab what you need instead of a straight up copy/paste operation. Enjoy!!
