Summary
SEO Lab is a free Chrome extension for recording SEO hypotheses and comparing later results. It is provided as-is and does not guarantee rankings, traffic, conversions, or revenue.
1. Acceptance
By installing or using SEO Lab (the “Extension”), you agree to these Terms. If you do not agree, do not install or use the Extension.
2. Operator and license
SEO Lab is developed and maintained by WebBiz (webbiz.tw), operated by Ben in Taiwan. WebBiz grants you a non-exclusive, royalty-free, revocable license to use the Extension for personal or commercial work, subject to these Terms. The current release is free and has no paid or donation feature.
3. Your responsibilities

- Do not use the Extension to access another party’s private data without permission.
- Do not use the Extension for illegal activity or to circumvent its security controls.
- Review test results yourself before making business or website decisions.
4. Google OAuth and data access
SEO Lab uses Google OAuth with read-only Search Console and Analytics 4 permissions. Its OAuth client has completed Google’s verification process. SEO Lab cannot modify your Google resources and does not store Google refresh tokens.
5. AI Overview checks
SEO Lab may fetch Google search result pages from your browser to detect AI Overview citations. Google may change its pages, rate limits, or anti-bot behavior at any time. AIO checks may pause or stop working, and you remain responsible for using this feature consistently with Google’s terms.
6. Local data and backups
Test records are stored locally as described in the Privacy Policy. WebBiz does not operate an account or cloud backup service for SEO Lab. Use Settings → Export JSON Backup if you need a separate copy.
7. No warranty
To the extent permitted by applicable law, the Extension is provided “as is” and “as available,” without express or implied warranties. WebBiz does not guarantee that experiments will improve rankings or business results, that verdicts will predict outcomes, that Google APIs will remain available, or that the Extension will be error-free.
8. Limitation of liability
To the extent permitted by applicable law, WebBiz is not responsible for indirect or consequential losses caused by reliance on verdicts, changes in search rankings, unavailable third-party services, or loss of local data. Nothing in these Terms excludes rights or liabilities that cannot legally be excluded.
9. Third-party services
SEO Lab connects directly to Google APIs, Google Search, Google Search Status Dashboard, Google Search Central RSS, and MozCast. Those services are governed by their own terms and may change or become unavailable without notice.
10. Changes and discontinuation
WebBiz may update, suspend, or discontinue the Extension or these Terms. The “Last updated” date on this page will change when the Terms change. You may stop using SEO Lab at any time by uninstalling it.
