Meta Tags for SEO in 2026: Title, Description, Open Graph and Twitter Cards
Which meta tags still matter for Google and social sharing, ideal lengths, how to write titles and descriptions that earn clicks, and how to generate them free.
The short answer
Three groups of meta tags still matter: the title tag and meta description for search results, Open Graph tags for previews on Facebook, LinkedIn and WhatsApp, and Twitter card tags for previews on X. Keep titles to about 50–60 characters and descriptions to about 150–160. The free Meta Tag Generator writes all of them from four fields and shows a Google-style preview with live character counts.
The title tag
The title tag is the clickable headline in search results and the text on the browser tab. It's one of the strongest on-page signals of what a page is about.
Length: Google truncates titles by pixel width, which works out to roughly 50–60 characters. The generator turns the counter red past 60.
How to write one:
- Put the main topic near the start: "Compress PDF Online Free" beats "Free Online Tool to Make Your PDF Files Smaller".
- Make each page's title unique.
- Add your brand at the end if there's room: "… | Lazyblink".
- Match the searcher's words. If people search "pdf to word", use that phrase rather than "PDF-to-DOCX conversion".
Google sometimes rewrites titles, especially when they're stuffed with keywords, too long or don't match the page. A clear, accurate title is rewritten less often.
The meta description
The meta description is the summary under the title in search results. It isn't a ranking factor, but it strongly affects whether people click.
Length: about 150–160 characters before truncation on desktop. The generator counts to 160.
How to write one:
- Say what the page gives the reader and why it's worth clicking.
- Include the main phrase; Google bolds words that match the search.
- Add a concrete detail: "Free, no signup, files never leave your browser."
- Don't repeat the title.
Google often writes its own snippet from the page text when it thinks that matches the query better. A good description still wins for the main queries.
Open Graph tags
Open Graph tags control the preview card when someone shares your link on Facebook, LinkedIn, WhatsApp, Slack and most messaging apps. Without them, the app guesses, often picking the wrong image or none.
The essentials:
| Tag | Purpose |
|---|---|
| og:title | Headline on the card (can differ slightly from the title tag) |
| og:description | One or two lines under the headline |
| og:url | The canonical address of the page |
| og:type | "website" for most pages, "article" for blog posts |
| og:image | The preview image |
Image size: 1200 × 630 pixels is the widely used standard. Keep important text away from the edges, since some apps crop to a square. Use an absolute URL (https://…), not a relative path.
Twitter (X) card tags
X reads its own tags, falling back to Open Graph for some fields. The key one is the card type:
- summary_large_image: a wide image above the title. Best for most pages with a good image.
- summary: a small square thumbnail beside the title.
The generator picks summary_large_image when you provide an image and summary when you don't.
Tags you can skip
- meta keywords: ignored by Google for over a decade.
- meta name="title": has no special effect; the title tag is what counts. The generator includes it for completeness, but it's harmless either way.
- revisit-after, rating and similar: not used by major search engines.
Tags worth adding by hand
The generator focuses on title, description and social tags. Most pages also need:
- viewport:
for mobile. - canonical:
to name the main version of a page. - robots, only when you want to stop indexing:

The stronger versions name the task, the benefit and a concrete detail, in the words people search with.
Tags by page type
- Tool or product pages: lead the title with the task ("Merge PDF"), and use the description for proof points (free, private, limits).
- Articles: use the headline as the title, and og:type "article" instead of "website".
- Local businesses: include the area in the title. Searchers add place names, and Google matches them.
- Category pages: describe the range ("40+ free PDF tools") rather than a single item.
Testing your tags
After publishing, check how the page looks when shared:
- Paste the URL into a private chat with yourself on WhatsApp or Slack.
- Use the platforms' own debugging tools (for example, Facebook's Sharing Debugger and LinkedIn's Post Inspector) to refresh a cached preview after you change tags.

Frequently asked questions
How long should a meta description be?
Aim for about 150 to 160 characters so it is not cut off on desktop search results.
How long should a title tag be?
About 50 to 60 characters. Google truncates by pixel width, so very wide letters can shorten that.
Do meta keywords help SEO?
No. Google has ignored the meta keywords tag for many years.
What size should an Open Graph image be?
1200 × 630 pixels is the common standard, with key content kept away from the edges.
