Page weight on mobile
A page too heavy for the phone in your customer's hand — and whether the weight is in the images (rarely) or the scripts (usually).
Why the other tools walk straight past it The owner tests on a laptop and the page is fine. On a phone it takes seventeen seconds. Nothing tells him, because he has never once stood where his customer stands. Then a consultant tells him to compress his images — confidently, and wrongly.
What it found One store: 1.6 seconds on desktop, 16.9 on mobile. The images were already compressed to the bone — 661 KB. The weight was 277 script files, 2.9 MB of them. The owner had decided his product was the problem. His product was fine. His page never opened.

Tag sprawl
Several Google tag containers on a single page — some of them fetched twice — and the real price your tracking charges your customer in patience.
Why the other tools walk straight past it Each container was added by some app or some setting, years apart, and nobody ever went back to take the old one out. Every one of them was installed to measure the store or to grow it. Together, they are why it crawls.
What it found One store was loading four Google containers. Two of them twice — the same bytes, fetched again. 933 KB across six files. More than every image on the page put together.
