Semrush dominates keyword research and backlink intelligence. PageGuard covers website health monitoring — performance, accessibility, SEO, and best practices — starting free.
ADA Title II Deadline: April 24, 2026
State and local government websites must meet WCAG 2.1 AA. Semrush does not audit accessibility. PageGuard monitors both website health AND accessibility compliance, alerting you before violations occur.

For website health monitoring, yes. PageGuard covers performance, accessibility (WCAG/ADA), technical SEO, and best practices in one automated scan — for as little as $9/month. It does not replace Semrush's keyword research or backlink database, which are entirely different features. If you're using Semrush mainly for its site audit functionality and don't need keyword or competitive intelligence, PageGuard is a far more affordable option.
No. Semrush's site audit tool checks for technical SEO issues like broken links, slow pages, and duplicate content — but it does not test for WCAG accessibility compliance or ADA violations. With the ADA Title II deadline approaching on April 24, 2026, accessibility monitoring requires a dedicated tool like PageGuard.
Yes — PageGuard lets you scan any website for free with no signup or credit card. You get a comprehensive health report covering Performance, Accessibility, SEO, and Best Practices in about 30 seconds. Automated monitoring with weekly scans and email alerts starts at $9/month.
Semrush is an SEO intelligence platform focused on keywords, backlinks, and competitive research. PageGuard is a website health monitor focused on keeping your site's performance, accessibility, SEO metadata, and best practices in good shape — and alerting you when they degrade. They serve complementary use cases, not the same one.
