Most of your traffic is on a phone, on a mediocre connection, in a browser with one hand. A page that converts on your 27-inch monitor may be unusable where it actually gets read.
What breaks on phones
- The hero image eats the whole screen and pushes the headline below the fold.
- Tap targets are too small or too close together.
- Forms trigger the wrong keyboard, or ask for typing where a choice would do.
- Sticky headers and cookie banners cover a third of the screen.
Speed is a conversion feature
Every second of load time costs conversions, and the biggest culprits are almost always uncompressed images and third-party scripts you forgot you installed. Fix those two before considering a rebuild.
Try it
Open your page on your own phone on cellular data, not wifi, and try to complete your own call to action. Note every moment of friction. That list is your next sprint.
