Frequently Asked Questions
What are meta tags and why are they important?
Meta tags are information tags in the <head> section of web pages that communicate content to search engines and social media. They significantly impact SEO, social share appearance, and how websites are displayed.
What types of meta tags can I check?
Title tags, description, keywords, viewport, robots, and other basic meta tags, plus Open Graph Protocol (OGP) tags (og:title, og:description, og:image, etc.), Twitter Card tags, and other custom meta tags.
What is the bookmarklet feature?
A bookmarklet is a function that lets you check meta tags of any website with one click while browsing. Drag the button to your bookmarks bar or use the copy button to copy the code and add it to your bookmarks.
How can I save the analysis results?
You can save results in two ways: Use 'Copy to Clipboard' to copy and paste into other apps or documents, or use 'Download as Text' to save as a .txt file. The filename automatically includes the domain name.
Can I use this in a local development environment?
This tool uses Cloudflare Pages Functions. In local development, Cloudflare functions are not available, so a warning message will appear. For testing, enter 'test' as the URL to display dummy data.
Can I analyze any website?
Yes, you can analyze any publicly accessible website. However, meta tags generated dynamically with JavaScript or sites with access restrictions may not provide complete information.
I got a timeout error.
The analysis has a 15-second timeout. Large sites or sites with slow responses may timeout. Please try again.
How do meta tags affect SEO?
Meta tags are crucial for search engines to understand page content and display in search results. Title tags and description meta tags are often used directly as the title and description in search results, significantly affecting click-through rates.
What's the difference between OGP and Twitter Card tags?
OGP (Open Graph Protocol) tags are a standard developed by Facebook that specifies how pages appear when shared on social media. Twitter Card tags are Twitter-specific and allow finer customization of display on Twitter. Both can set preview images, titles, and descriptions.
Is it a problem if a site has no meta tags?
Sites without any meta tags are at an SEO disadvantage because they can't properly communicate page information to search engines and social media. We recommend setting at least title and description meta tags.
