Page Speed Optimization
Page speed optimization is the practice of reducing how long a page takes to load and become interactive, improving user experience and conversion rates.
In depth
Page speed is governed by Core Web Vitals like Largest Contentful Paint and Interaction to Next Paint, which measure when the main content appears and how quickly the page responds to input. Improving them usually involves compressing and right-sizing images, deferring non-critical scripts, caching assets, and minimizing render-blocking resources so the visitor sees and can act on content within the first couple of seconds.
The most common pitfall is chasing a high lab score while ignoring real-world field data from actual visitors on mid-range phones and slow networks. In a quiz-funnel workflow, every extra second before the first question loads compounds across the whole flow, so optimizing the landing page and each quiz step keeps momentum, reduces early abandonment, and protects the downstream lead submissions you actually care about.
Example in practice
Frequently asked questions
How fast should my quiz funnel pages load?
Aim for the main content to appear in under 2.5 seconds and for the page to respond to input almost instantly. Faster loads reduce early abandonment and keep visitors moving through the funnel.
What usually slows a landing page down the most?
Large unoptimized images and heavy third-party scripts like chat widgets and trackers are the biggest culprits. Compressing media and deferring non-critical scripts typically delivers the fastest wins.
Does page speed really affect conversion rate?
Yes, slower pages consistently see higher bounce and lower completion rates. Even a one-second improvement on mobile can meaningfully lift quiz starts and lead submissions.
