Meta Tag Checker
Validate all your meta tags — OG, Twitter Card, and standard SEO tags
What are meta tags?
Meta tags are HTML elements in your page's <head> that provide structured information about your page to search engines, social media platforms, and browsers. They're invisible to visitors but crucial for how your content appears in search results and social shares.
There are three main categories of meta tags: standard HTML meta tags (title, description, robots), Open Graph tags (og:title, og:image, og:description) used by Facebook, LinkedIn, WhatsApp, and most social platforms, and Twitter Card tags (twitter:card, twitter:title, twitter:image) used specifically by Twitter/X.
Missing or misconfigured meta tags lead to poor search snippets, broken social previews, and lost traffic. A page without og:image will show as a plain text link on social media — getting far fewer clicks than a rich preview with an image. Similarly, a title tag over 60 characters gets truncated in Google results, potentially cutting off your most important keywords.
Common meta tag issues and how to fix them
1. Missing title tag or title too long
Google truncates titles over 60 characters. Keep your title concise and front-load important keywords.

2. Description meta tag missing or too long
Meta descriptions over 160 characters get truncated in search results. Write compelling descriptions that encourage clicks.

3. OG tags missing while standard meta tags exist
Many sites set title and description but forget OG tags. Social platforms prefer OG tags and may generate poor previews without them.
<meta property="og:title" content="Your Page Title" /> <meta property="og:description" content="Your page description" /> <meta property="og:image" content="https://example.com/image.png" /> <meta property="og:url" content="https://example.com/page" />
4. Duplicate or conflicting meta tags
Having multiple title tags or conflicting OG/Twitter tags confuses crawlers. Ensure each meta tag appears exactly once. Use the raw tags view in Unfurli to spot duplicates.
Frequently Asked Questions
What meta tags are most important for SEO?▾
The most critical meta tags are: title (under 60 characters), meta description (under 160 characters), og:title, og:description, og:image, and twitter:card. The title tag has the biggest impact on search rankings, while OG tags control how your page appears when shared on social media.
How many meta tags should a page have?▾
There's no hard limit, but a well-optimized page typically has 10-15 meta tags: title, description, viewport, charset, og:title, og:description, og:image, og:url, og:type, twitter:card, twitter:title, twitter:description, twitter:image, and optionally canonical, robots, and author.
Do meta tags affect Google rankings?▾
The title tag directly affects rankings. Meta description doesn't affect rankings but influences click-through rates from search results. OG tags don't affect Google rankings but are critical for social media visibility. The robots meta tag controls indexing behavior.
What's the difference between meta tags and OG tags?▾
Standard meta tags (like description and robots) are primarily for search engines. Open Graph (OG) tags are specifically for social media platforms — they control the title, description, and image shown when your URL is shared on Facebook, LinkedIn, WhatsApp, and others. Twitter has its own twitter: card tags that override OG tags on Twitter/X.
