What's the difference between meta name and meta property?

[lkovnih226]

I am seeing on my website having two meta element attributes as follows:

<meta property="description" content="page description">

and

<meta name="description" content="page description">

What is the difference between meta name and meta property? can anyone explain me?

Use only name. Property is not recognized in HTML specs for meta, so don't expect any parsers (including browsers and search engines) to treat your tag as valid. Google explicitly said it does not accept any property for meta elements. I think only one parser wants property, and that's only for one property value, and that's not for description.

There are two HTML specifications (specs) current now (HTML 5.2 and HTML Living Standard) and both link to MetaExtensions. There is no other authority for what HTML meta tags and attributes are valid.

An HTML validator is available online, and it's free. You can paste in content or give a URL and the validator will tell you what errors it finds.
