og:title¶
Wygard watches the content of the <meta property="og:title"> tag and alerts you when the title your pages show in social and chat previews changes.
| Scope | Tier | Default | Alert |
|---|---|---|---|
| Per URL | Basic | Off — enable via the OG group | 🟠 Heads-up |
Why it matters¶
og:title is the headline that appears when your URL is shared on Facebook, LinkedIn, Slack, WhatsApp, or pasted into most chat apps. It's independent of the <title> tag, so a template change can rewrite it — or drop it — without touching anything a search crawler flags. The first sign is usually a shared link that suddenly reads "Untitled" or shows the wrong page name.
The default severity is Heads-up: worth reviewing, rarely urgent. The test is off by default and is part of the OG selection group, so you can enable all four Open Graph tests together.
What Wygard checks¶
On every run, the crawler:
- Fetches the monitored URL.
- Extracts the
contentattribute of<meta property="og:title">from the<head>. - Compares the found value against the stored desired value.
Common alerts¶
- og:title changed — the tag now carries different text than the baseline.
- og:title not found — the tag was removed, so platforms fall back to the
<title>or the URL. - Multiple og:title tags — more than one was detected; scrapers pick one unpredictably.
Responding to an alert¶
- Open the alert and review the diff — Wygard shows the previous value and the new one.
- Decide whether the change was intended (a copy update) or accidental (a template regression, a plugin that stopped emitting the tag).
- If intended, click Set found value as desired to adopt the new title as the baseline.
- If accidental, restore the tag in your template and let the next crawl turn the test green.
Enable the whole OG group
og:title rarely breaks alone — a template change usually affects og:description, og:image, and og:url at the same time. Enable the OG selection group to watch all four link-preview tags together.
