Questions about best speed test tools

Which speed score actually matters?
Core Web Vitals from real visitors, which Search Console reports. A lab score from a test tool is a diagnostic — useful for finding the cause, not for judging whether you have a problem.
Why does my score differ between tools?
Because they test from different locations on different simulated connections. Compare a site against itself over time on one tool, never against a competitor across two.
Does ZENVIQ run these tools?
No. These are other companies' products. Tools built and hosted by ZENVIQ are marked separately on the tools page.
