A site that feels quick on office wifi can be unusable on the Market-Frankford line or in a rowhouse basement.
Where people actually open your site
Underground on the Broad Street Line. In a basement with a foot of water and no signal. On a narrow street where the rowhouses block everything.
That is where your page actually gets judged, and it is nowhere near where you built it. Eight seconds in that spot hands the job to whoever managed two.
What a page builder actually ships
Because a builder must handle any layout a customer might invent, it loads the tools for all of them in advance. Your handful of pages ends up carrying a layout engine, a motion library, and a full icon set you never opened.
Publishing does not trim any of that away. It goes out to every single visitor, on every page, from now on.
Photos straight off the phone
Straight off the handset, a single photo runs four to eight megabytes. A ten-shot gallery is therefore about fifty megabytes you are asking a stranger to pull down.
Run through a resizer, those ten total roughly four hundred kilobytes and look exactly the same on a phone. Nothing else you can do to a small site helps this much.
Widgets somebody sold you
The chat tab, the spinning testimonials, the coupon overlay, the embedded scheduler, the analytics tags, the cookie notice. Each one phones a different company, and your page stays unfinished until all of them respond.
With a weak connection they drop out one after another while the visitor looks at blank panels. Hardly any of them return more business than the wait costs.
Fonts that hide the text
Four font files usually means your sentences stay hidden until the final one lands. From the visitor side that is a white screen, which looks identical to a site that has crashed.
Two weights, served off your own server, with words showing in a fallback from the first moment. Nobody in Philadelphia has ever hired a roofer for the lettering.
Test it the way customers use it
Kill the wifi, ride a couple of stops on the Market-Frankford, and load your own homepage. That tells you more than any scoring tool will.
You should have your opening line read and the number located inside three seconds. Fall short and something has to be stripped off the page.
