Frequently Asked Questions
Meta tags are snippets of HTML in your page's <head> that tell search engines and social platforms what your page is about. The title tag and meta description directly affect your click-through rate in Google. A well-optimized title (50–60 chars) and description (150–160 chars) can significantly increase organic traffic without changing any content.
Open Graph (OG) is a protocol created by Facebook that controls how your URL appears when shared. Facebook, WhatsApp, LinkedIn, Telegram, Discord, Slack and many other platforms use OG tags to generate rich link previews with image, title and description.
The <title> tag is used by Google in search results and browser tabs. og:title is used by social platforms when sharing. They can differ — your page title might be "Free SEO Tool | Zlvox" while your OG title is more social-friendly like "Check Your Meta Tags in 5 Seconds".
Platforms cache OG data aggressively. After fixing your og:image, use Facebook's Sharing Debugger or WhatsApp's re-fetch to force refresh. Ensure your og:image is absolute (https://), at least 600×315px, and publicly accessible.
twitter:card controls how your page appears on Twitter/X. summary_large_image shows a large banner image — best for articles and tools. summary shows a small thumbnail — better for profiles. Always combine with og:image as Twitter falls back to it.
A canonical URL tells search engines which version of a page is the "original" one, preventing duplicate content penalties. Every indexable page should have a <link rel="canonical"> pointing to its definitive URL.
About This Meta Tag Analyzer

What Is a Meta Tag Analyzer?

A meta tag analyzer is a free online tool that fetches any public URL and extracts all its HTML meta tags — including the title tag, meta description, Open Graph tags, Twitter Card tags, canonical URL, robots directive and security headers. It then scores the page for SEO completeness and shows exactly how it will appear on Google, Facebook, WhatsApp, LinkedIn, and Twitter.

Why Audit Your Meta Tags?

Missing or misconfigured meta tags are one of the most common and easily fixed SEO issues. A missing og:image means your shared links appear as plain text on social media. A title over 60 characters gets truncated in Google search results. A missing canonical causes duplicate content issues. This tool catches all of these in seconds — and the built-in Generator helps you fix them instantly.

Meta Tag Generator — Key Features

The built-in meta tag generator lets you build complete, production-ready meta tag code covering basic SEO, Open Graph, Twitter Cards, robots directives, canonical URLs, and more. Live previews update in real-time as you type — so you see exactly what Google and social platforms will display before you publish. Copy or download the output and paste it directly into your <head>.
