Meta Tag Viewer

WHAT IT DOES

Meta Tag Viewer extracts every meta tag from the current page and presents them in a clean, organized display. The tool shows all meta tag attributes including name, property, http-equiv, content, charset, and viewport. Tags are automatically categorized into groups: SEO tags (description, keywords, robots, author), Open Graph tags (og:title, og:description, og:image), Twitter Card tags (twitter:card, twitter:title, twitter:description), viewport, http-equiv, theme, technical, and other. The tool performs a real-time SEO analysis, calculating a score based on critical tag presence, highlighting missing essential tags, and providing warnings for common issues like short descriptions or missing titles. Open Graph and Twitter Card presence is also analyzed to ensure social media sharing is properly configured.

WHERE IT RUNS

The extension runs entirely within your browser's local environment using the BotGentz framework. All meta tag extraction, DOM traversal, and SEO analysis occur on your machine without any network requests. No page content, meta data, or user activity is ever transmitted, uploaded, or stored externally. The tool works on any website and respects the browser's security boundaries, operating within the isolated extension sandbox.

HOW TO USE

Click the extension toolbar icon to open the Meta Tag Viewer panel. Click "View Meta Tags" to extract and display all meta tags from the current page. The display includes an SEO analysis section showing a score percentage and listing any missing critical tags. An Open Graph and Twitter Card section shows tag counts and warns about missing social media tags. Below these analyses, all meta tags are listed with their key-value pairs. Use the "Refresh" button to re-scan the page if content changes dynamically. Toggle "Show SEO analysis" to enable or disable the SEO score section. Toggle "Show OG/Twitter analysis" to control the social media analysis section. Toggle "Highlight critical tags" to visually mark important meta tags in the list. Toggle "Group by category" to organize tags by type. Click "Copy All Meta Tags" to copy the complete meta tag list to your clipboard.

THE META TAG EXTRACTION AND ANALYSIS ENGINE — WHY IT WORKS

Most meta tag viewers simply dump all meta elements without understanding their context or significance. This tool performs a three-layer analysis: first, it queries all meta elements using document.querySelectorAll("meta"), capturing every attribute including name, property, http-equiv, content, and charset. Second, it categorizes each tag based on its attribute patterns—recognizing Open Graph by the "og:" prefix on property attributes, Twitter Cards by the "twitter:" prefix, and SEO tags by well-known name values. Third, it runs a validation engine that checks critical tag presence against an internal list of essential tags, calculates an SEO score by comparing the number of present critical tags against the total possible, and generates warnings for issues like empty or insufficiently long descriptions. The title tag is also checked separately since it lives outside the meta collection. This triple-pass approach ensures comprehensive coverage and actionable insights.

THE PANEL

The Meta Tag Viewer panel is fully draggable by its title bar and remembers its position on screen per website. It snaps to the edges of your browser window for clean alignment. Collapse the panel to a compact icon strip using the minimize button, restoring it with a single click. Resize the panel by dragging any edge or corner; the meta tag display and analysis sections adjust proportionally. Press the Escape key to close the panel instantly. The panel maintains independent state for each browser tab, allowing you to analyze meta tags in multiple tabs simultaneously.

PLEASE NOTE

This extension requires the free BotGentz extension framework to be installed and enabled. Websites continuously evolve their meta tag usage and SEO best practices; while the analysis covers the most common standards, some sites may use custom meta tags not recognized by the categorizer. All meta data is extracted locally and is never transmitted, logged, or shared. The extension requests no network permissions and functions entirely offline. The source code is fully auditable and available for review.
