List Of All Metatags In HTML

Overview about Metatags

Metatags are part of HTML markup that describe page content for search engines and website visitors. Meta tags only appear in the code of the page, anyone can inspect them from the source code (Ctrl+U). We created an overview of meta tags that are still very important and those that are no longer important.

In short, meta tags are key elements for all search engines, appearing in the HTML of a website page and telling search engines what the page is about. They are the first impression and touchpoint for all search engines.

Why use Metatags?

Meta tags play an important role in SEO (Search Engine Optimization). Especially the use of title tags and meta descriptions is very important.

These tags are displayed by search engines as a small text entry in search results. Make sure the meta tags on your site are unique for each page and try to make them as attractive as possible. Both the relevant title tags and description tags must convince visitors to click on the link in the search results.

Create Custom Meta Tags

Use custom meta tags to store data that you need in Javascript, instead of hard-coding that data into your Javascript. I store my Google Analytics code in meta tags. Here’s some examples:

<meta name='google-analytics' content='1-AHFKALJ'>
<meta name='disqus' content='abcdefg'>
<meta name='uservoice' content='asdfasdf'>
<meta name='mixpanel' content='asdfasdf'>
