The Most Important Meta Tags
Title Tag
The element is the single most impactful on-page SEO factor. It appears in browser tabs, search results, and social shares.
| Rule | Guideline |
|---|---|
| Length | 50-60 characters (Google truncates at ~580px) |
| Primary keyword | Place near the beginning |
| Brand name | Append with a separator (" — Brand") |
| Uniqueness | Every page must have a distinct title |
Meta Description
Not a ranking factor, but heavily influences click-through rate. Write a compelling 150-160 character summary that includes the target keyword and a clear value proposition.
Google rewrites descriptions about 62% of the time, but a well-written description increases the chance it is used as-is.
Robots Meta Tag
is the default. Use noindex for pages you want crawled but not indexed (admin pages, thank-you pages, duplicate filtered views).
Open Graph Tags
Control how your pages appear when shared on Facebook, LinkedIn, and other platforms:
og:title— Share title (can differ from SEO title)og:description— Share descriptionog:image— Preview image (minimum 1200×630px)og:type— Content type (website, article)
Twitter Card Tags
Twitter uses its own meta tags alongside Open Graph fallbacks:
twitter:card— Card type (summary, summary_large_image)twitter:title— Falls back to og:titletwitter:description— Falls back to og:description
Common Mistakes
