Meta Tag Generator

The meta tag generator produces the complete head block for a page: title, description, canonical, robots, Open Graph tags for Facebook, LinkedIn, WhatsApp and Slack, and the Twitter card tags. Values are HTML-escaped, and it warns when a title or description falls outside the length search engines usually display in full.

How to use the Meta Tag Generator

  1. Enter the title and description — these are the two that matter most.
  2. Add the canonical URL and an absolute share image URL, ideally 1200 by 630 pixels.
  3. Pick the Open Graph type; website suits most pages and article suits posts.
  4. Generate, then paste the block into the <head> of your page.

Example

Input
Title, description, URL, image
Output
<title>…</title>
<meta name="description" content="…">
<meta property="og:title" content="…">
…

Common use cases

  • Setting up the head block for a new page or landing page.
  • Adding Open Graph tags so a link previews correctly when shared.
  • Fixing a page that shares with the wrong title or no image.
  • Producing a consistent tag set to hand to a CMS or a template.

Limitations and things to watch for

  • These tags describe a page; they do not make it rank. A correct head block is the floor, not the work.
  • Length guidance is approximate. Search engines truncate on pixel width rather than character count, so a title of wide capitals is cut sooner than one of narrow lowercase.
  • Social platforms cache aggressively. After changing tags you usually need the platform's own debugger to force a refresh, or the old preview persists.
  • No structured data is generated. JSON-LD depends on what the page actually contains and cannot be produced from a title and description.

Frequently asked questions

How long should a title and description be?
Around 50 to 60 characters for a title and 140 to 160 for a description usually display in full. Both are pixel-width limits rather than character counts, so treat the figures as guidance and write for a person first.
Do I need both Open Graph and Twitter tags?
Largely no. X falls back to Open Graph when the Twitter equivalents are missing, so og:title and og:description usually suffice. The one worth setting explicitly is twitter:card, which selects the large-image layout.
What size should the share image be?
1200 by 630 pixels, which is the 1.91:1 ratio the large-image card expects. The URL must be absolute — a relative path cannot be resolved by a crawler fetching the page from elsewhere.
Why does my link still preview with the old image?
Social platforms cache previews for a long time. Use the platform's sharing debugger to re-fetch the page; changing the tags alone will not clear a cached preview.
Does the keywords meta tag matter?
No. Google has ignored it since 2009 and it is not generated here. It was abandoned because it was trivially abused and told search engines nothing they could not read from the page.
