5 Things That Make Websites Slow, and How to Spot Them
You know that feeling when someone clicks on your website and then… nothing happens for what feels like forever? You’re sitting there, and you know they’re sitting there, and you’re both just waiting. And you start wondering if they’re still there. If they’ve already left. If they think your business is as slow as your website.
I hear this all the time from the women I work with. They’ll say, “My website feels slow,” or worse, they don’t even mention it because they’ve already assumed it’s just how websites work. It’s not. A slow website isn’t a personality trait. It’s a signal that something’s not working the way it should be.
Here’s the thing: speed matters. Not because of some algorithm obsession or because you need to be the fastest website on the internet. Speed matters because it’s about respect. When someone visits your site, they’re giving you their time and their attention. A slow website wastes both.
The good news? Most slow websites don’t fail because of one catastrophic problem. They fail because of small things that add up, pile on top of each other, and create this sluggish experience. The even better news? Once you know what to look for, spotting these things becomes pretty straightforward.
Let me walk you through the five most common culprits I see, and exactly how to check if your website has them.
1. Oversized Images (The Biggest Offender)
This is the number one reason I see websites slow down, and it’s almost always fixable in about fifteen minutes.
Here’s what happens: You have a beautiful photo. Maybe it’s a hero image at the top of your homepage, or a photo of you in your About section. It’s gorgeous, so you upload it directly from your phone or your camera. These files are enormous, sometimes 5 or 10 megabytes. Your website has to load that entire massive file every single time someone visits. If you’ve got three or four of these images on your homepage, you’re asking visitors’ browsers to download 20-40 megabytes of data before they can even see your content.
On a fast connection, this might take 3-5 seconds. On a slower connection, mobile network, or if someone’s using an older device, this could be 15-20 seconds. That’s an eternity online.
How to spot it: Open your website on a phone (especially if you’re on a regular cellular connection, not Wi-Fi). Click through to your homepage and your main pages. Time it. Does it feel sluggish? Does the page feel like it’s “loading” before the images appear? That’s usually oversized images.
You can also use free tools like Google PageSpeed Insights (just type in your website URL, and Google will tell you exactly which images are slowing things down). The report looks intimidating, but scroll down to the “Opportunities” section and look for anything that says “Properly size images” or “Serve images in next-gen formats.” That’s your smoking gun.
The opportunity: This is almost always an easy fix. You don’t need to replace the images. You need to compress them. Modern image compression tools can reduce file sizes by 80-90% without any visible loss of quality. Tools like TinyPNG, Squoosh, or ImageOptim do this automatically. Run your images through one of these tools before you upload them to your website, and you’ll immediately notice a difference.
If you’re using a modern website builder like Squarespace, Wix, or WordPress with a good theme, some of this compression happens automatically. But that doesn’t mean you should upload a 15-megabyte file and hope the builder handles it.
2. Too Many Plugins or Apps Running in the Background
I see this one a lot with WordPress websites, but it happens on other platforms too.
Here’s the scenario: You want to add a pop-up form to collect emails. So you install a plugin. Then you want to track what visitors are doing, so you add Google Analytics. Then you add a chat widget. Then a backup system. Then a security plugin. Then a speed optimization plugin (which is sort of funny because now you’ve got a plugin to fix the slowness created by all the other plugins).
Each one of these does something useful. But each one is also a small program that’s running in the background every single time someone visits your website. It’s like having ten browser tabs open on your computer, all trying to load at once. Technically possible, but noticeably slow.
I’ve seen WordPress websites with 20+ plugins, and I’d say about 40% of them weren’t even active or necessary anymore. They were just… there. Taking up space and consuming resources.
How to spot it: This one requires a little detective work, but it’s worth it. If you use WordPress, log into the back end and go to your Plugins section. Make a list of everything that’s installed. Go through each one and ask yourself: “Am I actively using this right now?” Be honest. If you added it six months ago and haven’t touched it since, it’s probably not earning its place.
You can also run a free audit through GTmetrix or Google PageSpeed Insights. These tools will often flag plugins or third-party scripts that are slowing things down, and they’ll actually tell you which ones are the biggest time-wasters.
The opportunity: Delete the ones you’re not using. Seriously. I’m not talking about deactivating them, I mean delete them. A deactivated plugin is still sitting there. Deleted is deleted.
For the plugins you’re keeping, there’s another opportunity: consolidation. Maybe you have one form plugin and a separate email capture plugin. You might be able to use just one tool and delete the other. Maybe you’re using both Jetpack and a separate backup plugin when one comprehensive solution would do the job.
This is where it gets fun, actually. You get to audit what’s really necessary and what’s just adding clutter. Fewer moving parts usually means a faster, smoother website.
3. Unoptimized Code and Render-Blocking Resources
This one sounds technical, but I promise it’s not as scary as it sounds.
Here’s what’s happening behind the scenes: When a browser loads your website, it has to read and process the code that makes up your site. Some of that code is necessary before anything can display. Some of it can wait. The problem occurs when non-critical code is blocking the display of critical content.
Think of it like this: You’re trying to read a book, but someone keeps handing you footnotes and appendices before you can get to the first chapter. You have to process all these extra materials before you can even start reading. That’s what render-blocking code does to your website.
This usually shows up as CSS files or JavaScript files that are loaded in the wrong order, or they’re loading synchronously instead of asynchronously (meaning one has to finish loading before the next one can start, instead of them all loading at the same time).
How to spot it: Use Google PageSpeed Insights (paste in your website URL). Under the “Opportunities” section, look for things like “Eliminate render-blocking resources” or “Defer unused CSS.” These will often give you a list of specific files that are slowing things down.
You can also look at the “First Contentful Paint” metric. This measures how long it takes before your visitor sees anything on the page. If that number is over 3 seconds, you likely have render-blocking issues.
The opportunity: This one might require a conversation with a developer if you’re using WordPress or have a custom site. But it’s worth doing because the payoff is big. Usually, the fix involves reordering code, minifying (compressing) JavaScript and CSS files, and setting certain resources to load asynchronously instead of blocking everything else.
If you’re using a simpler website builder like Squarespace or Wix, a lot of this is handled for you, which is one of the advantages of those platforms. But if you’re on WordPress or have a custom build, this is definitely worth investigating.
4. Hosting That Isn’t Suited to Your Website
Your website lives somewhere. On a server. And some servers are faster than others.
I see a lot of women using the cheapest shared hosting option they can find because, well, it’s cheap. That makes sense. Budget is real. But here’s what happens: You’re sharing that server with hundreds of other websites. If one of those websites suddenly gets a traffic spike, it can slow down your site. If another website gets hacked, it can affect yours. It’s like renting an apartment in a building where you have no control over your neighbors.
Meanwhile, better hosting options have moved way down in price over the past few years. You don’t need to spend $100+ per month on premium hosting anymore. But you also don’t need to be on the absolute cheapest option available.
How to spot it: Check where your website is hosted. Log into whatever control panel you use (like cPanel, if you’re on traditional shared hosting). Look at your hosting plan. Are you on “Economy” or “Starter” shared hosting? If so, there’s an opportunity here.
You can also run a speed test through Pingdom or GTmetrix. If they show slow Time to First Byte (TTFB), that’s often a hosting issue, not a website issue. TTFB measures how long it takes for the server to respond to the request. If that’s slow, no amount of image optimization is going to help you.
The opportunity: Upgrade to better hosting, or switch to a platform that handles hosting for you (like Squarespace or Wix). This doesn’t have to be expensive. Managed WordPress hosting through companies like Kinsta, WP Engine, or Bluehost’s premium tier costs $10-30 per month more than budget hosting, but you get significant speed improvements and much better support.
If you’re using a platform like Squarespace, Wix, or WordPress.com, your hosting is handled for you, so this isn’t something you need to worry about. The tradeoff is that you have less control over certain things, but you get reliability and speed that matches most small businesses’ needs.
5. External Scripts and Third-Party Tools That Load Slowly
Your website probably uses tools to do various jobs: email marketing services, analytics, chat widgets, payment processors, review widgets, scheduling systems. All of these are external services, and they add code to your website.
Here’s the problem: You don’t control how fast these external services are. If the company that runs your email service is having a slow day, your entire website might feel sluggish while it waits for their code to load.
I worked with a client once whose website was mysteriously slow, and we traced it to a single review widget that was loading from a slow server. It was adding 8 seconds to her page load time. Eight seconds! For a little widget that maybe 5% of her visitors were even looking at.
How to spot it: Open your website in any browser and press F12 (or right-click and select “Inspect”). Go to the “Network” tab. Reload the page. You’ll see a list of every single file, image, and external script that loads. Look for anything that takes a long time (you’ll see the time in milliseconds to the right of each item). Look especially for items where the domain name isn’t your website. Those are external scripts.
You can also use Google PageSpeed Insights, and look at the “Diagnostics” section. It will often flag third-party code that’s slowing things down.
The opportunity: Audit your external tools and ask yourself which ones are actually being used and which ones are just taking up space. Are you using that review widget? Is your chat tool generating actual conversations, or is it just there? Does your email service integration need to load on every single page, or just on specific pages?
Sometimes the opportunity is simple: Delete the script. But sometimes it’s about being smarter with when and where it loads. Many external tools have settings that let you load them only on specific pages, or only after the page has fully loaded, instead of blocking the entire page load.
The biggest opportunity here is consolidation, just like with plugins. If you’re using three different marketing tools, could you switch to one comprehensive platform? Fewer external dependencies usually means a faster, more stable website.
The Bigger Picture: Speed Is a Feeling
Here’s what I want you to understand: Website speed isn’t just a technical metric. It’s a feeling. When someone lands on your site and it’s fast, they feel respected. They feel like you’re professional and organized. When they land on a slow site, they might not consciously think, “This person isn’t organized,” but they feel it. It creates friction.
I talk to so many accomplished women who have grown so much in their expertise and confidence, but their website still looks and feels like an older version of them. A slow website falls into that same category. It’s a mismatch between who you are now and what your digital presence is saying.
The good news? You don’t need to completely rebuild. You don’t need to throw money at the problem. Most slow websites have one or two bottlenecks that, once fixed, make a dramatic difference. You get to choose what matters most to you and tackle that first.
Want to know what’s actually slowing your site down? You can use Google PageSpeed Insights to run a quick audit. Paste in your website URL and see what comes back. Don’t get overwhelmed by all the metrics. Just look for the three sections: Performance (your overall speed score), Opportunities (things you can fix), and Diagnostics (things to investigate).
If you’re feeling lost looking at the results, or if you want someone to help you figure out what’s actually critical versus what can wait, let’s talk about it. That’s exactly what I’m here for. No pressure, no sales pitch, just a conversation about what’s actually slowing you down and what might be worth fixing.
Frequently Asked Questions
Does my website need to be under 3 seconds to load?
Not necessarily. A 4 or 5 second load time is still pretty good, especially if most of that time is spent loading high-quality images that show off your work. What matters more is that the page starts displaying content quickly (that’s called First Contentful Paint). If your visitor sees something on screen within 2 seconds, they’re patient enough to wait for the rest to load. If they see a blank screen for 5 seconds, they’re gone.
Will using WordPress automatically make my website slow?
No. WordPress is fine. It’s what you put on WordPress that can make it slow. A well-built WordPress site with minimal plugins and properly optimized images is just as fast as a site built on any other platform. The difference is that WordPress gives you more rope to hang yourself with, which is why you see more slow WordPress sites. They’re not slow because of WordPress, they’re slow because of decisions made by the person running it.
Is using a page builder like Elementor or Beaver Builder going to slow down my site?
Page builders do add some extra code, which technically makes your site slightly slower than hand-coded HTML. But we’re talking milliseconds. The real slowdown comes when people use page builders to create overly complex designs with lots of animations, videos, and decorative elements. Keep your design simple and your page builder won’t be the bottleneck. And honestly, the convenience of a good page builder usually outweighs the tiny speed cost.
I can’t afford to upgrade my hosting right now. What should I focus on first?
Start with images. Image optimization costs nothing and typically gives you the biggest speed improvement for the least amount of effort. Once that’s done, audit your plugins and delete anything you’re not actively using. Those two things will often get you 80% of the way there. You can upgrade hosting whenever it makes sense for your budget.
