siteIQ vs GTmetrix
GTmetrix is a well-known page speed testing tool, built specifically for performance analysis with detailed waterfall charts. siteIQ covers speed too, but adds security, SEO and accessibility checks in the same free report — useful if you want a broader picture of a site's health, not just its load time.

Which one should you use?
If page speed is your only concern and you want deep waterfall-level detail on exactly how a page loads, GTmetrix's specialized performance view is genuinely strong at that one job. If you want a faster first check that also covers security headers, SEO fundamentals and accessibility — without needing a separate tool for each — siteIQ gives you that in one free report.
Many teams use both: a broad siteIQ check to catch issues across categories, and a dedicated speed tool for a deep performance dive once speed is flagged as the priority.
