Open Graph & Meta Tag Checker
Preview how any page looks when shared, and audit the tags machines read: Open Graph, Twitter cards, title, description and canonical. The same markup shapes your AI search visibility, because engines read these tags before they read your prose.
Getting the tags right
The og:image carries most of the click. Use 1200x630 pixels, the 1.91:1 ratio every major platform renders without cropping, and reference it with an absolute URL: relative paths break when scrapers resolve them. Keep the title tag near 60 characters and the meta description near 160 so neither gets truncated in results.
One set of Open Graph tags per page. Duplicate og:title or og:image tags force scrapers to guess, and different platforms guess differently. Set og:url to the canonical URL so shares consolidate to one address instead of splitting across variants. These are ten-minute fixes, and they compound: the same clean metadata that fixes your link previews is part of how AI engines decide what your page is about. The Honeyb agent handles this layer as part of the broader work.
Frequently asked questions
What is Open Graph?
Open Graph is a set of meta tags, originally introduced by Facebook, that tell platforms how to present a page when it is shared: its title, description, image and canonical URL. LinkedIn, Slack, WhatsApp, iMessage and most chat apps read the same tags, so one clean set of og tags controls your link preview almost everywhere.
What size should the og:image be?
1200 by 630 pixels, the 1.91:1 ratio that major platforms render without cropping. Keep the file under 5MB, and reference it with an absolute URL including the domain, because scrapers do not reliably resolve relative paths. A missing or undersized image is the most common reason a shared link renders as bare text.
Why does my link preview not update after I change the tags?
Platforms cache scraped previews, sometimes for days, so an old card can persist long after you fix the tags. Most offer a way to force a re-scrape: Facebook's Sharing Debugger, LinkedIn's Post Inspector, and for others simply appending a query parameter to the shared URL forces a fresh fetch. The tags this checker reads are always live, not cached.
Do meta tags affect AI search visibility?
Yes, as one layer of it. Title, description and structured metadata are part of how machines decide what a page is about before parsing the prose, and AI engines read them the same way scrapers do. The rest of the technical layer is crawler access, which the AI crawler access checker covers per bot, and the free AI visibility check audits the whole stack in one pass.
