There is nothing worse than clicking on a website and waiting forever for it to load. You might question your WiFi connection, but most of the time the website itself is to blame. And those extra seconds of wait time can be the deciding factor for a visitor to stick around or click over to a competitor.
The good news is that most site speed issues are fixable once you know what to look for. Here is how to diagnose what is slowing your site down and what you can do about it.

Start by Knowing Your Baseline
Before you can fix anything, you need to know where you stand. Google PageSpeed Insights is a free tool that gives you a performance score for both desktop and mobile, along with specific recommendations for what you need to address. GTmetrix is another solid option that gives you a more detailed breakdown of what’s loading and how long each element is taking.
Google now evaluates site performance through their framework called Core Web Vitals, which measures three specific things:
- How quickly your main content loads
- How fast your site responds to user interaction
- Whether your actual page layout shifts around as it loads
These are not just user experience metrics. They are also direct Google ranking factors, which means a slow site is also hurting your visibility in search results.
A good target for load time is under three seconds, and under two seconds is ideal. If your site is taking five seconds or more, visitors are likely leaving before they ever even see your content.
What is Weighing Your Site Down
There are a handful of common culprits behind most slow websites. Here is what to look for:
Hosting quality
Your website hosting is the foundation everything else runs on. A cheap, shared hosting plan puts a ceiling on your website performance regardless of how well everything else on the site has been optimized. If your server response time, also called Time to First Byte (TTFB), is over 200 milliseconds, your hosting may be the primary issue. This is one area where it pays to invest in a quality solution and provider.
If you are on a fully managed platform like Squarespace or Shopify, unfortunately you have less control over this. If you are experiencing consistent lag, reach out to their support team to check whether there is an issue with the specific server your site is running on.
Page Size and Content Load
All of the content (copy, images, video, text, etc) on your page contributes to its total size, from images and text to video files and third-party widgets. A long page loaded down with content takes longer to deliver to a visitor’s browser. If you have pages that are trying to do too much then breaking them into smaller, more focused pages is worth considering.
Image Files
Images are one of the top causes of slow load times and also one of the easiest to fix.
A few things to check:
- Keep image dimensions reasonable. There is rarely a reason for an image to be wider than 2500 pixels, and most images on a page can be significantly smaller than that.
- Use the right file format. Standard photos should be JPEGs. PNGs are better suited for graphics and illustrations or anything requiring a transparent background. For modern browsers, WebP is an even more efficient format worth considering.
- Compress your images before uploading. Tools like Squoosh, TinyJPG, or ImageOptim can significantly reduce file sizes without visible quality loss. A good file size target is under 300KB per image, and under 150KB where possible.
- Web-Ready Photography. If you work with a professional photographer, ask them to provide web-ready files in addition to the high-resolution versions. High-res photography files are not suitable for web use as-is and require additional time to resize and compress.
WordPress Plugins and Third-Party Scripts
If your site runs on WordPress, the amount of plugins used are worth inspection. Every active plugin adds files that have to load before your content appears. The same goes for third-party scripts from analytics platforms, marketing tools, chat widgets and social media integrations. Each one of these integrations adds significantly to your load time.
Do a quarterly audit of your plugins and deactivate or remove anything you are not actively using. Be sure to keep everything updated regularly, both for performance and security. And when you need new functionality, look for solutions that consolidate features rather than adding another plugin to the stack to solve a specific need.
Making Sense of What You Find
Once you run your site through PageSpeed Insights or GTmetrix, you will get a list of specific recommendations. Some of these are straightforward to address on your own. Others, like server-level caching, code minification or render-blocking resource management, are more technical and may need handing off to a developer.
The most important thing is not to ignore the results. A slow site is quietly costing you visitors, rankings, and credibility every day it goes unaddressed.
When it Makes Sense to Hand it Off
If you have worked through this list and your site is still underperforming, or if you would rather have a qualified team handle ongoing performance monitoring and optimization as part of a broader website management plan, that is exactly what our website maintenance services are built for. We also build every new client website with performance as a foundational requirement, not an afterthought.
Not Sure Where to Start?
If running through this list feels overwhelming, or you want a professional to look at your site before any changes are made, we offer website audits as part of our website growth services that take the guesswork out of the process. We assess your site’s performance, identify the highest-impact issues and give you a clear roadmap of what needs to be addressed and in what order. Whether you take that roadmap and run with it or want us to implement it for you, you’ll walk away knowing exactly where your website currently stands and what it needs.
