One of the first things we look at to see if a customer even needs a website redesign is a website’s health. A big part of this is analyzing it with PageSpeed Insights to view how a users are experiencing a business’s current website on both desktop and mobile. Quality in Mind Candles Squarespace website did not have a passing PageSpeed Score before we redesigned the website.
First Contentful Paint (FCP) is a user-centric metric for measuring perceived page load speed. FCP measures how users perceive the performance of a website, rather than what a speed test tool measures. A good FCP score to provide a good user experience is 1.8 seconds or less. Before the redesign, Quality in Mind Candle’s website was scoring at 3.2 seconds.
Total Blocking Time (TBT) measures the total amount of time that a page is blocked from responding to user input, such as mouse clicks, screen taps, or keyboard presses. The sum is measured by adding the blocking potion of all long tasks between First Contentful Paint and Time to Interactive. Any task that executes for more than 50 ms is a long task. The amount of time after 50 ms is the blocking portion.
Speed Index measures how quickly content is visually displayed during page load. This means when a customer would go to her Squarespace site, the page wouldn’t load for nearly 9 seconds.
Largest Contentful Paint (LCP) is important to look at because it marks the point in the page load timeline when the page’s main content has likely loaded. A fast LCP helps reassure the user that the page is useful. For a good user experience, we’re looking for an LCP score of 2.5 seconds or less. The old website took nearly 13 seconds to load on the old site!
