About the service

SeoTools (“the Service”) provides various utilities for web production and is offered free of charge. No account registration with the Service is required. Some features that integrate with Google APIs require authorization through your own Google account.

Operator and contact

Operator: セオリコ

For questions about these terms or the Service, contact us through the contact form.

Conditions of use

Anyone may use the Service freely.
You may use tool outputs for commercial or non-commercial purposes.
Please avoid automated bulk access or any use that places excessive load on the Service.

Site structure checker

The tool fetches only publicly accessible pages of the target site. Pages that require login or are disallowed by robots.txt are not fetched.
To limit load on the target site, we cap the number of pages per run, the request interval, and the number of runs per site per day. These limits may change without notice.
You must not use the tool to place load on a third party's site or to infringe anyone's rights. You are responsible for the sites you choose to check and for how you use the results.
Results are cached for 24 hours and are also shown to other users who check the same URL.
Site owners who want to exclude their site can add a Disallow rule for User-agent: SeoryToolsSiteStructureChecker to robots.txt, or contact us through the contact form.

Disclaimer

Tools are provided as-is; we do not guarantee accuracy or completeness.
We are not liable for any damage arising from use of the Service.
Content and URLs may be changed or discontinued without notice.
In the site structure checker, link position classification (body / sub content) and broken-link detection are heuristic estimates based on HTML structure and may contain errors.

Intellectual property

Text, design, source code, and other materials on the Service are owned by the operator. You may freely use the outputs generated by the tools themselves.

Changes to these terms

These terms may be changed without notice. The revised terms take effect when posted on this page.
