Frequently Asked Questions
Everything you need to know about technical capabilities, quotas, and security.
How many URLs can I audit at once?
You can audit hundreds to thousands of URLs per run. Google Apps Script provides generous daily fetch quotas, allowing you to comfortably inspect site migrations, paid ad destinations, and client landing page lists without external crawling software.
Does Link Monitor store my URLs on external servers?
No. The extension operates completely within your own Google account and Google Spreadsheet session. Zero URL parameters, site structures, or client data are sent to or stored on third-party servers.
Does it follow multiple redirect hops?
Yes. Link Monitor traces 301 and 302 redirect paths to their final destination, detecting redirect loops, insecure HTTP downgrades, and dropped UTM attribution parameters.
Can I schedule automated monitoring checks?
Yes. Using Google Sheets built-in time-driven triggers, you can configure automatic hourly, daily, or weekly audits with conditional formatting alerts.
Is this tool completely free?
Yes. DesignScript provides this tool 100% free with no trial limits, subscriptions, or credit card requirements.
