So what are meta tags? Meta tags are basically tags that enclose meta data that are used in the HTML of a webpage. As i said it is basically a meta data so that means what ever you enclose within a meta tag will not appear on the webpage itself but will be used by the search engines and social medias like a meta data for the webpage.

So today i bring to you these essential meta tags that you should know and use in order to improve the SEO of your webpage. Lets see:

You may be using different types fonts, smileys, symbols and emojis in your webpage which may be using one or more special characters which would be defined in a particular character encoding but not in the other you are using. And that may lead to the unsuitable display of desired contents in the webpage. So it is always a good idea to define a character encoding at the top of a webpage and that too which covers majority of characters so as to ensure your desired content is displayed properly. Generally UTF-8 is preferred as it covers almost all character encoding and almost all the browsers supports it.
<meta charset="UTF-8">

2) <meta name="viewport" content="width=device-width, initial-scale=1.0">

From HTML5 developers got the control over the viewport of a webpage. The viewport meta tag basically lets you decide the dimension and scaling of your webpage when it opens up in a browser. width=device-width tells the browser to follow the screen width of the device where the page is displayed. initial-scale=1.0 tell the browser to display the page with the following initial zoom level.
