# Social Networks

Social Networks like Facebook and Twitter use Open Graph meta tags, and Compass validates that you use them appropriately.

All the meta properties that start with og: and twitter:card must be in the head tag of your HTML pages.

# URL mandatory

For Compass, the og:url meta tag is mandatory:

<meta property="og:url" content="https://thenews.com" />

And its content must be exactly equal to the canonical page URL.

# Title mandatory

You must always include the og:title meta, with the headline of the article:

<meta property="og:title" content="Boy jumps comet!" />


Remember that the article headline is not the same thing as the webpage title.

# Description mandatory

Always include a description of the article:

<meta property="og:description" content="[DESCRIPTION]" />

# Image mandatory

You must always add the article's illustration image information, split in 3 meta tags:

<meta property="og:image" content="https://images.unsplash.com/photo-1534361960057-19889db9621e" />
<meta property="og:image:width" content="5184" />
<meta property="og:image:height" content="3456" />

The image URL you write here must return a 200 HTTP code and be at least 600 pixels wide, although we recommend 1200 pixels for best quality.

The image format must be one of JPG, PNG, WEBP, or GIF.

Finally, the width and height you provide must be the exact image measurements.

# Type optional

If you use the og:type meta tag, it must contain either article or website and nothing else:

<meta property="og:type" content="article" />
<meta property="og:type" content="website" />
