🌍 Hreflang Tag Checker – SEO Tool for International Websites

The Hreflang Tag Checker is a powerful SEO utility designed to streamline the process of auditing a website’s hreflang implementation. It extracts all hreflang attributes from a given URL and then crawls each linked language version to verify the existence of a correct return link (rel=“alternate” hreflang).

This ensures that your multilingual or multi-regional site is correctly set up for international SEO and helps search engines serve the right content to the right users in the right language.

✅ Features:

- Parses all hreflang tags on a page

SEO tool for auditing hreflang tag implementation on multilingual/multi-regional websites

Ensures that hreflang tags are correctly implemented by verifying that each linked language version includes a proper return link (rel="alternate" hreflang) pointing back to the current page, which helps search engines serve the right content to the right users in the right language.

User navigates to a webpage, clicks the extension icon, and the tool automatically extracts all hreflang tags from the page, then fetches each linked URL to verify that it contains a return hreflang tag pointing back to the original page. Results are displayed in the popup showing which links have correct back-references and which do not.

Target users: SEO professionals / Web developers / International website administrators / Digital marketers managing multilingual sites

The extension only analyzes the currently active tab; it does not support batch URL checking or site-wide crawling beyond the hreflang links found on a single page.
The extension does not have a settings page or configuration options visible in the source.
The original author (Adapt Worldwide) link is present but commented out in the UI, so no external service interaction beyond fetching linked URLs for validation.

Monetization

No paid features detected

The extension is completely free with no paid features, no subscription gating, no payment integration, and no upgrade prompts. The 'pro' keyword matches in the static analysis are false positives: they appear in 'processing page...' (popup.html), 'protocol' (script.js), and the verified_contents.json file hash payload. There is no billing, license, or premium feature code.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension runs entirely client-side on the current tab. It queries the active tab, extracts hreflang tags via chrome.scripting, and fetches linked URLs directly. There is no login UI, no account creation, no session handling, and no redirection to a web app that requires authentication.
