Generate the SEO, Open Graph and X (Twitter) card tags for any page, and preview how the link will look when someone shares it on Facebook, LinkedIn or WhatsApp.
The tags that actually matter
Lots of old meta tags do nothing today. Search engines ignore meta keywords, and tags like “revisit-after” were never used. The ones worth having are:
- Title: the clickable headline in search results and the browser tab.
- Meta description: the short summary under the title in search results.
- Canonical: tells search engines which URL is the main version when the same page is reachable at several addresses.
- Robots: only needed when you want to keep a page out of search with
noindex. - Open Graph (og:title, og:description, og:image and friends): control the preview card on Facebook, LinkedIn, WhatsApp, Slack and most chat apps.
- X card tags: do the same on X. If they are missing, X falls back to Open Graph.
Getting the share image right
The image does most of the work when a link is shared. Use 1200 × 630 pixels, keep important text away from the edges because some apps crop to a square, and keep the file under about 1 MB. A plain photo of a stock office will be ignored; a clear headline or product shot gets clicks.
If you change the image after sharing a link, Facebook and LinkedIn may keep showing the old one. Their sharing debugger tools let you refresh the cached preview.
On WordPress, use your SEO plugin
WordPress themes and SEO plugins already print most of these tags. If you paste the generated code as well, you will end up with two of each and the apps will pick one at random. Instead, put the title, description and share image into the Rank Math or Yoast box under your post. Use the code from this tool on sites without a plugin, on landing page builders, or to check what your plugin should be producing.
Before publishing, check the title and description length with our SERP snippet preview, which measures them in pixels the way Google does.
Common questions
Do meta keywords help SEO?
No. Google has ignored the meta keywords tag for over 15 years, and Bing treats it as a possible spam signal. This generator leaves it out on purpose.
Why does Facebook show the wrong image?
Usually because og:image is missing, too small, or Facebook cached an older version. Add a 1200 × 630 image and refresh the preview with Facebook’s Sharing Debugger.
Where do I paste these tags?
Inside the head section of the page, before the closing head tag. On WordPress, use your SEO plugin’s fields instead of pasting code.
Is the og:url the same as the canonical?
It should be. Both should point to the main, clean version of the page, without tracking parameters.
