Why is my share preview empty?

Usually because og:image is a relative URL, or the image is not publicly reachable. The address must be absolute, include the protocol and return 200 without a login.

Meta tag generator

Q: How do I generate meta tags?

Fill in the title, description and canonical, and optionally an OG image and site name. The tool assembles a ready block and shows lengths and URL problems as you type. Copy the result into your page template.

Q: Does this meta tag generator run locally?

Yes. Everything is computed in your browser and the values you type are not sent to CometWeb.

Q: Should I add meta keywords?

No. Google stopped using the tag in 2009. Its presence neither helps nor hurts — it is simply redundant, which is why this generator does not emit it.

Q: How long should the title and description be?

Roughly 65 characters for the title and 160 for the description usually fit a result. Google truncates by pixel width rather than character count, so treat those as budgets rather than hard rules.

Write your page title and description, preview the link and copy the tags into your site.

Checks

Block for your <head>

Enter a title to see the output…

This meta tag generator assembles the <head> block: title, meta description, canonical, Open Graph and Twitter Card. It checks lengths, absolute URLs and a large card with no image as you type. Everything runs locally in your browser — nothing is uploaded.

Which meta tags actually do something

Title and description are the only two fields that decide the click in search results. The rest of the block governs social sharing.

Meta keywords is not a thing. Google stopped using it in 2009. This generator does not emit it, and neither should yours.

og:image has to be absolute. A relative URL works on your own page and nowhere else — it is the usual reason a pasted link renders an empty frame.

Treat lengths as a budget. Google truncates by pixel width, so the same character count renders differently for “Illinois” and “WWW”.

Write for the specific page

Use the title to identify the topic and the description to explain what visitors will find. Give products, categories and articles their own values. Length indicators help editing but cannot guarantee the exact search appearance.

The fields and their jobs

Ttitle: The result title link, the browser tab and bookmarks. The only element the HTML standard requires.
Dmeta description: A proposed snippet. Not a ranking signal, but it moves CTR.
OGOpen Graph: The share preview — Facebook, LinkedIn, Slack, Discord and most messengers.
TWTwitter Card: The preview variant for X. summary_large_image needs an image; summary works without one.
