Common Questions
What's a good page load speed?
Target < 3 seconds on desktop, < 5 seconds on mobile. Faster is always better.
Will optimizations affect functionality?
No! Optimizations improve speed without changing functionality. Test after major optimizations.
Should I optimize for mobile or desktop first?
Mobile first! Over 60% of traffic is mobile. But optimize for both.
