Frequently Asked Questions
Is CheckWebs really free?
Yes. The tool hub is built around free, public website checks with no signup wall, no forced trial, and no hidden paid step before you see useful results.
What makes this different from a single SEO checker?
CheckWebs is designed as a broad website operations hub. You can audit SEO, accessibility, DNS, uptime, SSL, email authentication, security headers, robots.txt, sitemap health, and technology stack from one place.
Are result pages easy to share with my team?
Yes. Tool pages, domain pages, and quick-answer pages are easy to copy and share, so teams can revisit checks quickly and keep a clear history of findings.
What is included in the full website check?
The full website check runs the core technical diagnostics together so you can scan SEO, accessibility, AI readiness, DNS, SSL, headers, redirects, sitemap, robots.txt, email setup, and other trust signals in one report.
Who is CheckWebs useful for?
It is useful for marketers, SEO teams, developers, founders, agencies, and anyone who needs a quick website snapshot before publishing, onboarding a client, auditing a competitor, or troubleshooting a traffic drop.
How fresh are the checks?
Most checks run live when requested and some responses are cached briefly to keep the experience fast. If a website changes, rerunning the check will refresh the latest result set.
Can agencies use these pages in client workflows?
Yes. The current UI is designed to make reports easier to scan, share, and turn into next actions, which makes it useful for internal QA and lightweight client reporting.
