Share tags are set

Share tags are the title and one-line summary that show up when someone pastes your link into a text, email or social post. Some AI readers use them as a backup summary too.

What this is

When you paste a link into a text message, Facebook, LinkedIn or Slack, a little preview card appears with a title and a sentence. That card is built from Open Graph tags, two hidden lines in your page that say what to show.

They are called og:title and og:description. “og” is short for Open Graph. It is a standard that started at Facebook and every big platform now reads.

They sit right next to your page title and description and often say nearly the same thing.

Why it matters to you

This is a 2-point check, so it is a nice-to-have. It is on the list for two reasons. First, anything that shares your link reuses these tags, so a missing one means an ugly or empty preview when a client texts your site to a friend. Second, several AI extractors fall back to Open Graph when the normal page title is thin.

It takes ten minutes, and it makes your links look better everywhere.

What we look for

We read the og:title and og:description meta tags on your homepage.

  • Pass: both are present with content. Full points.
  • Warn: only one of the two is present. You get 1 of 2 points.
  • Fail: neither is present. Zero points.

We do not check og:image or any other Open Graph tag.

Whether you can fix this yourself

Yes. Every major platform writes these for you or gives you a field. Most sites already pass.

How to fix it

Set both tags on every page:

<meta property="og:title" content="What you do, in your city" />
<meta property="og:description" content="One clear sentence." />

Say what you do and where. Reusing your page title and meta description word for word is fine.

WordPress

Yoast SEO and Rank Math both write these automatically from your SEO title and description. Edit the homepage, open the plugin panel, and look for a “Social” tab. Fill in the title and description there if the defaults are empty.

Squarespace or Wix

Both write Open Graph tags from your page’s SEO title and description. If either is blank, fill it in (see Title and description are filled in). Squarespace also has a “Social image” and “Social sharing” section in page settings.

Shopify

Your theme writes these from the page title and description. Fill those in under Online Store, then Preferences.

Your own site or a developer

Paste the two lines above into the <head> of every page, or into the layout component so every page gets them.

How to check it worked

Paste your homepage link into a message to yourself in iMessage, WhatsApp or Slack. If a preview card shows your title and a sentence, the tags are working. Then run the free check again.

Do not worry about

The preview image. A missing og:image makes the card plain, but it does not affect this check or how AI reads your page.
