Finish the tags that shape your link previews
Some of your sharing tags are missing, so links to this page show a half-finished preview: a headline with no image, or a description pulled from wherever.
Why it matters
Chat apps, social networks, and messaging apps build the preview card from three tags: og:title, og:description, and og:image. Each missing tag drops one piece of the card, and the app fills the gap by guessing from the page. The result is a link that looks unfinished next to every other link in the same channel, which costs clicks you already earned.
How you would notice it
- A link you share shows a headline but no image.
- The preview text changes each time you share the page.
- One page previews correctly while another on the same site does not.
What to do
Stage 1
- Find which tag is missing. The recommendation names it, or search the page source for og:title, og:description, and og:image.
- Add the missing lines to the head section, using the page title and description you already wrote for search results.
The image must be a full address starting with https://, and about 1200 by 630 pixels. A relative address silently fails in every preview.
<meta property="og:title" content="Emergency Plumbing in Fresno | Clearwater Plumbing">
<meta property="og:description" content="Same-day emergency plumbing across Fresno. Licensed, insured, and on site within the hour.">
<meta property="og:image" content="https://www.example.com/images/preview-plumbing.jpg">Stage 2
- Refresh the stored preview before you share the link anywhere important. Messaging apps cache what they read the first time.
Paste the page address into either debugger and use its refresh control. Without that step, the old preview can follow the link around for weeks.

Confirm it worked
Paste your page address into a share debugger and confirm the card shows the title, description, and image you chose. Re-run the Siege Test and confirm the Open Graph recommendation is gone.
