How to Check Open Graph Tags on Many Websites at Once

Link previews come from a few og: meta tags, and a list of sites can be read for them in one run. Doing it site by site works for a handful. For a list, the bulk Open Graph checker reads up to 100 domains at once (500 after a free Google sign-in) and shows which tags are set, their values and what is missing.

It reads tags only: it does not load the image or show you what any app will display.

What Open Graph tags are

Open Graph is a set of meta tags, introduced at ogp.me, that tell apps what title, description and image to show when a link is shared. The protocol's required tags are og:title, og:type, og:image and og:url. The tool also lists og:description, og:type, og:url and twitter:card when present.

The by-hand way

1. Open the home page and view the source.
2. Search for og: and note the title, description and image values.
3. Repeat for every site on your list and keep a sheet of what is missing.

Step 1: paste the list

One domain per line, or upload a CSV. Emails and URLs work too.

Step 2: run it

Each home page is requested once, five at a time.

Step 3: read the rows

A row with title, description and image set has all three core tags. A flagged row names what is missing. Filter to those and download the CSV. To compare page titles at the same time, use the bulk website title checker; the older post on checking page titles and meta descriptions in bulk covers that side.

What this check cannot do

• Only the home page's HTML is read.
• The image isn't downloaded, so its size and availability aren't checked.
• Tags added by JavaScript aren't seen.
• Each app decides what it shows, so a complete set of tags is not a guarantee of a preview.

Next: contact emails on the same list

This tool reads websites, not email addresses. For the contacts, the verify page gives the first 100 checks free with a Google sign-in, no card.
