Why Is it Important to Have a Dedicated Site Speed Team?

The importance of site speed is more crucial than ever because it’s now a bigger ranking factor for Google and other search engines. It’s also key to providing a good user experience (UX) on your website.

So, why is it important to have a dedicated site speed team to optimize your website’s loading times? Unless you’re a developer, optimizing your site speed can prove to be a challenging feat, especially if you’re juggling other business tasks.

Numbers have continued to prove the importance of good site speed:

These stats are important to understand because every day your website performs badly, the higher the chance that a user will not come back to your site and purchase from a competitor.

How to test your site speed

Wondering how to test your site speed? We’ve got you covered.

There are tools online that you can use to scan and analyze your website to see what your current site speed is. It’s also important to know that a site will have a different speed score on mobile than on desktop.

When running your website through tools such as Google Search Console, Page Speed Insights (PSI), and Lighthouse, the results will often include updating your code. The recommendations these tools will give you directly impact the Core Web Vitals (CWVs).

PageSpeed Insights web vitals

Google’s Core Web Vitals are as follows:


Largest Contentful Paint (LCP) metric reports the render time of the largest image or text block visible within the viewport.

To provide a good user experience, sites should strive to have Largest Contentful Paint occur within the first 2.5 seconds of the page loading.

To ensure you’re hitting this target for most of your users, a good threshold to measure is the 75th percentile of page loads, segmented across mobile and desktop devices.


First Input Delay (FID) measures the time from when a user first interacts with a page (i.e. when they click a link, tap on a button, or use a custom, JavaScript-powered control) to the time when the browser is actually able to begin processing event handlers in response to that interaction.

To provide a good user experience, sites should strive to have an FID score of less than 100 milliseconds.


Cumulative Layout Shift (CLS) measures the total of all individual layout shift scores for every unexpected layout shift that occurs during the entire lifespan of the page. To provide a good user experience, sites should strive to have a CLS score of less than 0.1.


First Contentful Paint (FCP) measures when the browser renders the first bit of content from the DOM, providing the first feedback to the user that the page is loading.

The First Contentful Paint time stamp is when the browser first rendered any text, image (including background images), non-white canvas, or SVG.


DOMContentLoaded (DCL) event fires when the initial HTML document has been completely loaded and parsed without waiting for stylesheets, images, and subframes to finish loading.

If loaded as usual, stylesheets slow down DOM parsing as they’re loaded in parallel, “stealing” traffic from the main HTML document.


Total Blocking Time (TBT) metric measures the total amount of time between First Contentful Paint (FCP) and Time to Interactive (TTI), where the main thread was blocked for long enough to prevent input responsiveness.


Time to Interactive (TTI) is a non-standardized web performance progress metric defined as the point in time when the last Long Task finished and was followed by 5 seconds of network and main thread inactivity.

Why is it important to have a dedicated site speed team?

So if you can test your website’s loading time yourself, why is it important to have a dedicated site speed team?

Unless you are a developer, the items identified by tools like PSI may seem impossible to optimize. That’s where an experienced site speed team can step in to help!

PageSpeed Insights optimizations

Here are a few examples of website issues/recommendations listed by PSI that may be tough to know how to fix without developer knowledge or expertise:

  • Reduce unused JavaScript
  • Reduce the impact of third-party code
  • Avoid an excessive DOM size
  • Avoid chaining critical requests
  • Avoid non-composited animations
  • Serve images in next-gen formats
  • Defer offscreen images
  • Reduce initial server response time
  • Reduce unused CSS
  • Eliminate render-blocking resources
  • Serve static assets with an efficient cache policy
  • Minimize main-thread work
  • Enable text compression

PSI uses cookies from Google to deliver its services and analyze traffic. They can collect field and lab data from the web to collect the data for each CWV and the recommendations/errors.

PSI analyzes only one page at a time (rather than giving a full site overview), so you should keep that in mind when using that tool.

If you type in your homepage URL, it will give you the desktop and mobile score for just that page. This is important to know because your homepage’s speed could be really fast, but the rest of your site is poor, resulting in a bad experience for your users.

As websites become more complex with more moving parts, it’s important to have a dedicated team that keeps track of all custom functionality.

As we all run the race to have the best and most custom websites, these more unique features can easily break.

It’s important to have a team that knows your website inside and out to ensure nothing breaks or is impacted in a negative way when making code changes to improve site speed and user experience.

Meet WebFX — your dedicated site speed optimization agency

WebFX provides a committed project manager (PM) to walk through things with you. This PM will help ensure nothing breaks on your website during speed optimizations and can look at how your site’s UX can be improved alongside the speed enhancements.

Your dedicated PM will also walk through the optimizations completed by our team, review data reports, and the plan for the next quarterly optimizations.

We look to optimize websites once a quarter (rather than every month or once a year) because we have found that it gives us time in between optimizations to see how the site and user data were impacted.

We are able to better see patterns and trends to help us invest our time in what will make the biggest impact to drive the best results for your business.

We have also seen that websites typically undergo changes to images, content, plugin updates at least a few times a quarter, so our team can then make sure those updates align with best practices and optimize them if not.

WebFX’s recurring site speed optimization services also include our in-house proprietary software, MarketingCloudFX, that can help you track your competitors’ site speed, CWVs over time, and more!

Our services also include synthetic browser testing to double-check for any optimization issues as well as daily automatic back-ups to ensure nothing is lost or overwritten during updates!
