Are your Core Web Vitals failing due to a LCP over 2.5s? Let's fix it! The Largest Contentful Paint (LCP) is one of the most important metrics in measuring web performance - more specifically - it's the one that measures loading speed. While absolutely vital for UX and conversions, still 40% of world wide sites fail at passing this metric. Let's deepdive in understanding and improving the LCP and get those numbers up!

In the pursuit of improving website performance, it's easy to fall prey to common misconceptions. Let's dive into some of these myths and uncover the truth behind optimizing your website's speed.

When it comes to building Single-Page Applications (SPAs), developers face unique challenges in meeting the Core Web Vitals requirements. CWV, while crucial for optimizing website performance, were not initially designed with SPAs in mind. Google has made efforts to accommodate SPAs, but as of now, there is no straightforward way for SPAs to excel in this aspect. In this blog, we will explore the impact of SPA architectures on Core Web Vitals and discuss potential solutions to overcome these challenges.

Round-Trip Time (RTT) is a crucial metric in web performance that measures the duration for a signal to travel from a client to a server and back, directly impacting Time to First Byte (TTFB) and overall loading times.

It’s March 12th, 2024, a big day in the web performance community! Today we see Interaction to Next Paint take its (rightful) place in the Core Web Vitals, replacing First Input Delay (FID) as the primary metric for measuring website responsiveness and interactivity. This comprehensive guide, which includes insights from 13 web performance specialists, will provide you with the knowledge and practical advice you need to master INP.

As FID is being removed from Google interfaces, endpoints and libraries, we will need to align accordingly. The calculation of our UX score will be reshaped as well.

We have an INP date. And this doesn't only mean that FID stops being a Core Web Vital metric. FID is facing more consequences and will never be the same again. Here's what to expect.

By saying "Goodbye speed scores; Hello real users," Shopify is getting rid of the single Lighthouse score and switching to RUM data from real users. We can only applaud this choice. For Shopify merchants, who is eligible and what information will you still be missing?
