Meta tags tell search engines and social networks how to read and display your page. You do not need dozens; you need the right handful, done correctly. Here is the short list that matters.
The essentials
- Title (
<title>): the single most important on-page SEO element. Aim for about 60 characters. - Meta description: the snippet under your title in search results. About 155 characters; it does not directly rank you, but it drives clicks.
- Canonical (
<link rel="canonical">): tells search engines the preferred URL when similar pages exist. Prevents duplicate-content dilution. - Robots (
<meta name="robots">): whether to index the page and follow its links. Most pages wantindex, follow.
The social set
When your link is shared, Open Graph and Twitter tags decide how the card looks:
- og:title, og:description, og:image, og:url, og:type: used by Facebook, LinkedIn, WhatsApp, Slack, and more.
- twitter:card, twitter:title, twitter:description, twitter:image: used by X. Set
twitter:cardtosummary_large_imagefor the big-image layout.
The image is what makes a shared link stand out. Use roughly 1200 by 630 pixels.
Generate the full set
- Open the Meta Tags Generator.
- Fill in your title, description, URL, and image once.
- Copy the complete block into your page’s
<head>.
It reuses your title and description for the social tags, so you fill them in one place.
Then preview before you ship
Tags are only right if they render right. Check the search snippet with the Google SERP Snippet Preview and the share cards with the Social Media Preview.
