What is the SEO Meta and OpenGraph Generator?
This tool generates the meta tags that control how a page appears in search results and when shared on social platforms, title, description, OpenGraph, and Twitter Card markup, with a live preview of each.
Meta tags in a page's head tell search engines and social platforms how to represent it. The title and description influence what appears in search results, while OpenGraph and Twitter Card tags determine the preview card shown when a link is posted.
Getting these right has an outsized effect relative to the effort involved. A link shared without OpenGraph tags renders as a bare URL; the same link with a title, description, and image renders as a card that attracts far more attention.
Length limits matter because platforms truncate. Search result titles are generally cut around 60 characters and descriptions around 155 to 160, though the real constraint is pixel width rather than character count. Writing to those limits means the important words survive.
How to use the SEO Meta and OpenGraph Generator
- Enter your page details. Provide the title, description, canonical URL, and the image you want used in previews.
- Check the previews. See how the page will appear in search results and as a social card, including where text will be truncated.
- Adjust to fit the limits. Trim the title and description so the meaningful content is not cut off.
- Copy the generated tags. Paste the complete markup into your page's head element.

Writing within these ranges keeps your text from being truncated mid-sentence.
Title: 50-60 characters
Description: 150-160 characters

always removes the end. The OG image must be
an absolute URL; relative paths will not resolve
when a platform fetches the page.Common use cases
- Preparing a page for launch. Ensuring a new page presents correctly in search and on social platforms from the outset.
- Fixing broken share previews. Diagnosing why a shared link renders without an image or description.
- Standardising tags across a site. Generating a consistent template for every page.
- Improving click-through. Rewriting titles and descriptions to be more compelling within the length limits.
Features and limitations
- Generates title, description, canonical, OpenGraph, and Twitter Card tags.
- Live previews of search and social appearance, including truncation points.
- Character counters against the practical limits for each field.
- Output is plain HTML ready to paste into a head element.
- Search engines treat the description as a hint rather than a directive, and frequently rewrite it based on the query, so the description influences but does not control what is displayed.
Frequently asked questions
How long should a title and description be?
Roughly 50 to 60 characters for a title and 150 to 160 for a description. The real limit is pixel width rather than character count, so put the important words first, truncation always cuts the end.
Do meta keywords still matter?
No. Google has ignored the keywords meta tag for many years after it was comprehensively abused. There is no benefit to including it.
What size should the OpenGraph image be?
1200 by 630 pixels, a 1.91:1 ratio, is the widely supported standard. Keep the file under about 5MB and use an absolute URL, relative paths do not resolve when a platform fetches your page.
Why is my social preview not updating?
Platforms cache preview data aggressively. Use the platform's own debugging tool, Facebook's Sharing Debugger or LinkedIn's Post Inspector, to force a re-fetch after changing your tags.
Do I need both OpenGraph and Twitter Card tags?
X falls back to OpenGraph when Twitter Card tags are absent, so OpenGraph alone works. Adding Twitter Card tags gives you explicit control over the card type, which is worth it if you want a large image card.
Will good meta tags improve my ranking?
Not directly. The title is a modest ranking signal and the description is not one at all. What they affect is click-through rate from results, which is valuable in itself and can influence performance indirectly.
