Free Meta Tag Generator — SEO + Open Graph + Twitter Cards

Fill in your page title, description, URL and share image to instantly generate a complete set of SEO, Open Graph and Twitter Card meta tags. Copy the output straight into the <head> of any HTML page or your framework's head() helper.

Features

How to use

  1. Step 1. Fill in title, description, page URL and image URL.
  2. Step 2. Click Generate.
  3. Step 3. Copy the meta tags and paste them inside your <head>.

Real use case: fixing an ugly link preview before a launch announcement

A team is about to post a product launch on LinkedIn and Slack. A test share shows the company name as the title, no description, and a random logo crop — because the page has a <title> but no Open Graph tags.

Generating the meta block gives title, description, og:title, og:description, og:image and Twitter card tags in one paste. The developer adds them to the page head, re-runs the share preview, and the post now shows the intended headline and hero image on every platform.

How Meta Tag Generator works

The generator writes three overlapping families of tags: standard SEO tags (title, description) that search engines read, Open Graph tags (og:*) used by Facebook, LinkedIn, Slack, WhatsApp and Discord, and Twitter Card tags for X.

Field lengths follow what actually renders: roughly 60 characters for titles and 155 for descriptions before truncation in search results. The tool escapes quotes and angle brackets in your values so the emitted HTML stays valid.

og:image must be an absolute https URL — relative paths are silently ignored by crawlers, which is the single most common reason a preview shows no image.

Frequently Asked Questions

What's the ideal title and description length?

Aim for 50–60 characters for titles and 150–160 for descriptions — beyond that, Google truncates them in the SERP.

Do I need both Open Graph and Twitter tags?

Open Graph covers Facebook, LinkedIn, WhatsApp and most chat apps. Twitter falls back to OG, but adding twitter:card explicitly gives you the wide image layout.
