OG Image Checker & Twitter Card Validator
This has no effect on rankings. It decides whether a shared link renders as a full-width image or a bare grey text row.

Where the official Twitter Card Validator went
X removed the preview from its Card Validator in 2022, and cards-dev.twitter.com/validator no longer works as a validator. It still shows up in search results, which is why people keep landing on it.
There is no replacement inside X. The one exact check left is to paste your URL into the X post composer and look at the card before you post — that is X fetching your live tags. Everything else, including this tool, reads the same tags X reads and tells you what is missing before you get that far.
If you fixed your tags and X still shows the old card, it is almost always X’s cache, not your page. Adding a query string such as ?v=2 makes X treat it as a new URL and fetch it again.
This has nothing to do with rankings
Open Graph tags are not a ranking signal and never have been. They decide what a link looks like when someone pastes it into Slack, LinkedIn, Facebook or X.
That is still worth getting right, because the difference is stark: a full-width image with a headline, or a bare grey row with a truncated URL. The second one does not get clicked.
The specifics that trip people up
1200×630 pixels is the size that works everywhere — a 1.91:1 ratio that fills the large card on every major platform without cropping the wrong part.
The URL must be absolute. Crawlers do not resolve relative paths, and this is the single most common reason a card renders blank in production after working locally.
SVG does not work. Facebook and X both reject it. Use PNG or JPG.
Set twitter:card to summary_large_image. Without it X falls back to a small thumbnail, which wastes the image you made.
How to use it
- Enter the page URL — The tool reads the live page.
- Check the preview — If the image is missing here, it will be missing when shared.
- Fix the tag table — Required Open Graph properties are marked.
Frequently asked questions
What size should an og:image be?
1200×630 pixels. That 1.91:1 ratio fills the large card on every major platform without cropping.
Why is my share preview blank?
Most often a relative og:image URL — crawlers do not resolve those. Other causes: SVG format, an image behind authentication, or a cached older version on the platform side.
Do Open Graph tags affect SEO?
No. They affect how shared links render, which drives click-through on social platforms. Rankings are unaffected.
Do I need Twitter Card tags if I have Open Graph?
X falls back to Open Graph, so it mostly works. The exception worth setting is twitter:card — without summary_large_image you get a small thumbnail instead of the full-width card.
Does the Twitter Card Validator still work?
No. X removed its preview in 2022 and has not shipped a replacement. Check the tags with a tool like this one, then confirm in the X post composer, which shows the card before you publish.
