From HTML source to full SEO audit in seconds

1

Get the Page HTML Source

Open the website you want to check in your browser. Right-click and select 'View Page Source'. Press Ctrl+A then Ctrl+C to copy all the HTML.

💡 You only need the <head> section — but pasting the full page source works too. Our parser automatically finds the relevant tags.

2

Paste and Analyze

Paste the copied HTML into the input area above and click 'Analyze Meta Tags'. All meta tags are extracted and audited instantly in your browser.

💡 Your data never leaves your browser — the analysis is 100% client-side. Safe for any content including internal pages.

3

Review the Audit Report

Review your SEO score, check the SERP and social previews, and read the specific recommendations for each issue found. Prioritize Critical issues first.

💡 Click on any check in the audit report to see the exact fix recommendation and the correct HTML snippet to use.

Parses all meta tags from pasted HTML: title, description, keywords, author, robots, canonical, viewport, charset, and all Open Graph and Twitter Card tags.

SEO Score & Grade

Calculates an overall SEO score (0–100) and letter grade (A–F) based on the presence, quality, and optimization of all detected meta tags.

Live SERP Preview

Shows exactly how the page appears in Google search results — title, URL, and description — with truncation warnings and character count indicators.

Open Graph Preview

Renders a live Facebook/LinkedIn link card preview using the page's og:title, og:description, og:image, and og:url tags.

Every tag is individually checked against best practices. Missing, too short, too long, or poorly configured tags each receive a specific, actionable fix recommendation.

Use Cases

Who Uses the Meta Tag Checker

From SEOs and developers to digital marketers — anyone who needs to verify page metadata.

Audit Competitor Pages

Competitive Research

View source on any competing page and check their meta tag strategy. Understand what titles, descriptions, and OG images top-ranking competitors use.

Debug Social Previews

Debugging

When a LinkedIn or Facebook share shows wrong title, image, or description — paste the page source to instantly see what's in the OG tags and find the issue.

Pre-Launch SEO Checklist

QA & Launch

Before launching any new page, check that all critical meta tags are correctly set. Catch missing og:image, absent canonical URLs, or accidentally left noindex tags.

CMS Template Verification

Development

Verify that your WordPress, Shopify, or custom CMS is correctly generating meta tags for different page templates — product pages, blog posts, category pages, etc.

Client SEO Reporting

Client Work

Generate a clear, visual audit report for client pages. The score and color-coded issues make it easy to communicate SEO problems and priorities to non-technical clients.

Twitter Card Validation

Social Media

Before sharing content on Twitter, paste the page source to verify the twitter:card, twitter:image, and twitter:title are correctly configured and will render as expected.

Deep Dive

The Complete Guide to Auditing Your Website's Meta Tags

Why Auditing Meta Tags Matters

Meta tags are invisible to website visitors but visible to every search engine, social platform, and link-sharing tool. A missing og:image means every Facebook and LinkedIn share shows a gray box. A title tag over 60 characters gets truncated in Google with an ellipsis. An accidental noindex tag makes a page invisible to Google entirely. Regular meta tag audits — especially before launches and after CMS updates — catch these issues before they affect your traffic and social performance.

The Most Common Meta Tag Mistakes

Based on auditing thousands of pages, the most common critical mistakes are: (1) Missing og:image — the page shares without any visual on social media. (2) Title tag too long — truncated in Google results with '...' cutting off important keywords. (3) Duplicate meta descriptions across multiple pages — Google penalizes duplicate descriptions across a site. (4) Accidental noindex on important pages — sometimes pushed by staging settings left enabled in production. (5) Missing canonical URL — leaving the page vulnerable to duplicate content from URL parameters. Our checker catches all five automatically.

How to Interpret Your SEO Score

Our SEO score is calculated from 15 individual checks across three categories: SEO meta tags (title, description, canonical, robots), Social media tags (OG and Twitter), and Technical tags (viewport, charset). Each check has a point value based on its real-world SEO impact. Critical checks (title, og:image, viewport, noindex) carry the most weight. The score is a starting point for prioritization — a score of 85 means you're well-optimized but there's still room to improve social sharing or minor warnings.

Debugging Social Media Preview Problems

When shared links on Facebook, LinkedIn, or Twitter show incorrect information, the source of truth is the page's OG and Twitter Card tags. Our checker extracts these directly from the HTML source and renders the actual preview, so you can see exactly what the platform will show without using each platform's own debugging tools (Facebook Sharing Debugger, LinkedIn Post Inspector, Twitter Card Validator). Common causes of preview problems: tags are missing entirely, og:image URL is incorrect or uses HTTP instead of HTTPS, or tags are rendered by JavaScript after the initial HTML response.

Meta Tag Auditing for Technical SEO

Technical SEOs use meta tag audits as part of larger site audits. Key signals to check: robots meta tag for unintentional noindex/nofollow directives, canonical URLs for proper self-referencing and cross-domain canonicalization, viewport presence for Google's mobile-first indexing requirements, charset declaration for correct character encoding especially on international sites. These technical tags are easy to overlook because they rarely cause visible frontend errors — they only affect search engine behavior.

Keeping Meta Tags Correct Over Time

Meta tags can break silently after CMS updates, theme changes, plugin conflicts, or developer deployments. A routine that works: (1) Run a meta tag check on your top 10 highest-traffic pages monthly. (2) Always check new page templates before launch. (3) After any CMS major update or theme change, recheck 5–10 random pages. (4) When integrating new tools (HubSpot tracking, tag managers, SEO plugins), verify they haven't overridden existing meta tags. Our checker makes this routine quick — paste source, check score, done.

“The noindex detection alone has saved me twice. Both times a developer accidentally pushed noindex to production pages. This checker caught it in our pre-launch QA.”

Aisha Mohammed

“I love that it shows the actual Twitter card and OG previews from the page source. I can debug social sharing issues without needing the Facebook Sharing Debugger every time.”

Chris Nakamura

“The scoring system makes it easy to explain SEO meta tag issues to clients. A grade C with red critical issues is much more persuasive than a list of technical changes.”
