Latency is King: Why Speed is Critical for Building Apps + How to Speed Up Your App

Speed can make or break the user experience of a website or app. Latency is a vital component that impacts everything from bounce rates to conversions, SEO rankings, user experience, and ultimately, the desired goals of your project.

Even minor delays can have a massive effect: Amazon estimates a 1% drop in sales with every 100ms increase in load time. With net sales of $574.8 billion in 2023, the smallest drop in performance costs them billions of dollars.

Let’s dive into why this is the case, and why it has never been more important to optimize the speed of your applications and sites, on both desktop and mobile:


Slow Loading = Lost Customers

Let’s start with some facts:

Slow Loading = Bad SEO

SEO is super important for most sites/apps because it helps you gain visibility for search queries related to your product or service organically. And with 8.5 billion Google searches a day (2 trillion a year), getting organic search traffic can have a very material impact on the success of your project. But as the data shows, Google has no interest in showing users slow-loading sites/apps, as they know better than anybody how big of an impact slow loading has on user behavior. Google just like everybody else wants their users to have a good experience, so they have no interest in showing them slow-loading sites/apps.

Slow Loading = Especially Bad for Mobile Users

There are over 5.3 billion mobile internet users globally already, and mobile’s share of global internet traffic has witnessed growth of 75% from 2015 to 2024. This trend is almost certain to continue as things like 5G, Starlink, and other connectivity improvements continue to advance, coupled with the behavior and usage preferences of the younger generations. It’s not enough for your site/app to perform well on desktop, it needs to be fully mobile optimized in order to keep up with today’s (and tomorrow’s) modern internet users.
