Meta Tag Checker for WordPress: Audit Your WP Site's SEO Tags (Free)
Use our free meta tag checker to audit WordPress sites. Find missing title tags, broken Open Graph images, missing schema markup, and plugin conflicts. Step-by-step WP SEO audit guide.
Why WordPress sites need a meta tag checker
WordPress powers over 40% of the web, but its meta tag implementation depends heavily on which theme and SEO plugin you use. A meta tag checker designed to work with WordPress can reveal hidden problems that plugins like Yoast, Rank Math, and All in One SEO sometimes miss or even cause through configuration conflicts.
Common WordPress meta tag issues include duplicate title tags (theme header plus SEO plugin output), missing Open Graph images when featured images are not set, canonical tag conflicts between plugins, and schema markup that fails Google's Rich Results Test. Our free [meta tag checker](https://meta-tag-checker.appsnap.co.uk/checker) detects all of these in under two seconds.
Unlike plugin-specific dashboards that only show you what the plugin thinks it output, our checker fetches the final rendered HTML the same way Googlebot does — so you see exactly what search engines and social platforms see, including any tags injected by caching layers, header injection plugins, or theme functions.
How to check meta tags on a WordPress site
The process is identical regardless of your WordPress setup. Paste your full page URL into the meta tag checker and the tool fetches the HTML, parses every meta tag in the head section, and produces a scored report. Here is how to use it specifically for WordPress troubleshooting:
- Step 1: Paste the URL of your most important page (homepage or top landing page)
- Step 2: Review the title tag — WordPress themes sometimes output a second title tag that conflicts with your SEO plugin
- Step 3: Check the meta description — if missing, your SEO plugin may not be configured correctly
- Step 4: Verify Open Graph tags — og:image often breaks when WordPress media library URLs change
- Step 5: Validate schema markup — WordPress generates Organization and Article schema via plugins, but it may be invalid
- Step 6: Check the canonical tag — ensure it points to the correct URL, not a staging or AMP variant
- Step 7: Review security headers — many WordPress hosts do not set HSTS or X-Content-Type-Options by default
Common WordPress meta tag problems
After auditing thousands of WordPress sites, certain problems appear repeatedly. Understanding these patterns helps you diagnose issues faster than trial-and-error plugin swapping.
Duplicate title tags are the most common. This happens when your theme hardcodes a title tag in header.php AND your SEO plugin outputs one via the wp_head hook. The result: two title tags in the HTML, which confuses Google. Our checker flags this immediately.
Missing og:image is equally common. WordPress SEO plugins use the featured image as the og:image, but if no featured image is set, or if the image URL has changed, the tag is missing or broken. Without og:image, Facebook and LinkedIn link previews show plain text — reducing click-through rates by up to 60%.
Yoast SEO meta tag checking
Yoast SEO is the most popular WordPress SEO plugin, but its settings panel does not show you the actual rendered HTML. Our meta tag checker fills this gap by showing you exactly what Google sees after all plugins and theme hooks have run.
Common Yoast issues the checker finds: the title template variable not resolving (showing %%sitename%% instead of your site name), social media image settings pointing to deleted media files, and schema markup that conflicts with theme-generated schema. Run the checker after every Yoast settings change to catch regressions.
If you manage WordPress sites for clients, combine the meta tag checker with our [invoice generator](https://invoice-generator.appsnap.co.uk) to bill for SEO audit work professionally — include the checker report as a deliverable.
WordPress schema markup validation
WordPress plugins generate schema markup automatically, but invalid schema is worse than no schema — it can prevent rich snippets and, in rare cases, trigger manual actions. Our checker detects JSON-LD, microdata, and RDFa from any WordPress plugin and validates the structure.
The most common schema issues on WordPress: Article schema missing required author or datePublished fields (often because the post author display name is empty), LocalBusiness schema with incomplete NAP data, and Product schema where the price or availability fields are empty. For a complete walkthrough of schema types, see our [schema markup guide](/blog/schema-markup-structured-data-guide).
After fixing schema issues, validate with Google's Rich Results Test and then re-run our checker to confirm the fixes are live. For tracking your WordPress site's Core Web Vitals alongside meta tags, check the full SEO score breakdown in the report.
Frequently Asked Questions
Paste your WordPress page URL into our free meta tag checker. It fetches the final rendered HTML — including tags added by Yoast, Rank Math, or your theme — and validates every meta tag against SEO best practices. Takes under two seconds.
Yes. Our checker shows you the actual rendered HTML that Yoast produces, including any title template variables, social media settings, and schema markup. This is more accurate than checking Yoast's settings panel, which does not show the final output.
This usually means your theme hardcodes a title tag in header.php while your SEO plugin also outputs one via wp_head. Remove the hardcoded title from your theme or use the add_theme_support('title-tag') function to let WordPress handle it natively.
Set a featured image on every post and page. WordPress SEO plugins use the featured image as the og:image. If the tag is still missing after setting one, check that the image URL in your media library is valid and uses HTTPS.
