Everyone has seen a PageSpeed score. Very few people have been told what to do about one.
Squizzie reads your score from Google’s PageSpeed Insights and then does the part Google doesn’t: it separates the score into what you can fix, what needs a developer, and what isn’t yours at all.
Naming the third parties
Third-party scripts are usually the biggest slice and the least visible. Squizzie attributes that load to forty-seven named services, so instead of "render-blocking resources" you see which chat widget, which pixel, which font host and which analytics tag is costing you.
Several of those you’ll have chosen deliberately and will keep. That’s fine. The value is knowing what they cost you in load time, rather than worrying about a score that turns out to be mostly a marketing tag you’d forgotten about.
An adjusted score
Alongside your raw score, Squizzie shows what it would be without the third-party load. The gap between the two is the honest measure of how much of the problem is actually your site.
It’s narrow, and nobody buys an analytics tool for it. It answers a question shop owners ask constantly and rarely get a straight answer to.
