Your site feels fast at your desk. That office WiFi flatters it. Your customers get the real version, on mobile data, standing in a queue somewhere, and most of them just leave.
It happened in front of me once. A shop owner opened her own homepage on her phone and we both sat there watching a white screen. Then a heavy video woke up. Then the photos arrived one by one, slow as you like. She laughed, but you could tell it stung. That page was her pride.
Most days it is the same three culprits. Photos straight off a camera, far bigger than any phone screen needs. A heavy video sitting right at the top. Images far down the page loading anyway, long before anyone scrolls to them. My fixes are boring, honestly. I resize the photos and squeeze them down. I swap the top video for a still image on mobile. I let the lower images wait their turn. Nothing clever. It just works.
This is my daily bread, full stack development. I build in Next.js and WordPress, and I lean on Lighthouse to spot the heavy stuff. Quick pages keep people. Slow pages hand them to whoever loads first.
When did you last open your own site on mobile data, away from your desk? Be honest.
My work lives on my Contra profile, and you can send me a project there if your site needs this fix.
