How To Measure Web Performance in WordPress (Tools & Steps)

Last updated on Feb 15th, 2024 | 5 min

TL;DR: Measuring WordPress site performance for SEO involves using tools like Google PageSpeed Insights, GTmetrix, and others to analyze speed and SEO aspects. A successful audit identifies slow-loading elements, SEO weaknesses, and recommends optimizations to enhance site speed, user experience, and search engine ranking. This process is crucial for maintaining competitive web presence and user satisfaction.

A website that loads in one second has a conversion rate 3X higher than a website that loads in five.

On top of that, the average speed of a first-page Google result is 1.65 seconds. In this context, having a slow website means leaving money on the table.

An SEO and speed audit doesn’t necessarily take much time and resources, but their benefits are pretty solid. For instance, a misconfigured plugin or a conflict between plugins considerably slows your website. Running an audit is a great way to identify culprits you can fix later on.

Fortunately, you have many solid ways to perform audits and check for site speed and SEO issues! Indeed, Google PageSpeed Insights is a crucial tool, but it’s not the only one! 

We discovered a few tools to check for site speed and SEO issues that deserve your attention. Before introducing them to you, it’s a good idea to learn more about speed and SEO audits. 

Speed/SEO Audits at a Glance

A speed audit is when webmasters or experts analyze all the factors that impact the site speed. The main items responsible for a website's performance are:

  • host platform
  • WordPress theme
  • plugins installed

An SEO audit is a more complex activity and includes evaluating all the parts responsible for the site's rank in people’s search results. Loading speed is a ranking factor, so a speed audit is a key component of an SEO audit. Altogether, due to its importance, the speed audit gets a special mention.

Enterprises and small businesses should be audited to fix any inherent issues. Amazon and your small online business are in the same boat when it comes to audits!

A good plan and the proper tools are the pillars of an efficient audit.

However, the tools differ from site to site and depend on the site complexity, auditor experience, and time allocated for this task. Yet, the basic tools are the same for all websites.

Let’s take a deeper look at the following seven easy ways to check for site speed and SEO issues on your WordPress website.
