Why is performance important for conversion?

Performance directly affects conversion because speed is the first experience of interacting with a product, and it determines whether a person reaches the needed action at all. If a site is slow, the user doesn't have time to get absorbed in the value proposition, which means they don't buy, don't subscribe, and "never reach the button."

The main reasons:

#1. Speed shapes the first impression

The mind judges a site within fractions of a second. If it "thinks," a person concludes: "this will be long and complicated." Conversion actions require engagement, and slow loading kills it from the very start.

#2. Every extra second lowers motivation

When a page takes 4-6 seconds to open, the brain picks the path of least resistance: closing the tab. The user's goal already requires effort (buy, compare, pay), and lag adds resistance.

#3. The slower it is, the lower the trust

Distrust means abandoning the action. If a site performs poorly at the most basic stage (loading), the user fears that payment, delivery, and service will be just as bad.

#4. Performance is directly linked to bounces and session length

Slow means less scrolling, fewer clicks, fewer viewed blocks, meaning the offer doesn't have time to sell itself. A fast page, on the other hand, lets you carry the user through the funnel to the end, and that increases conversion.

Summary: good performance means reduced friction on the user's path. Less friction means higher engagement, trust, and willingness to complete the target action.
