Site speed is a revenue metric, not a vanity score

Why page speed matters for affiliate conversion, and the changes that usually have the biggest payoff.

Faster pages tend to convert better. The exact gap varies by site and audience, but the direction is consistent: slow pages cost clicks.

Mobile bounce drops noticeably when you remove heavy above-the-fold elements like hero carousels and unused plugins.

The three changes with the biggest payoff are usually: server-side caching at the host level, serving images in modern formats at the right dimensions, and deleting the plugins nobody remembered installing.

None of that is glamorous. All of it beats redesigning your logo.
