If you're asking "why is my website slow?", the answer is usually one of a few common causes, and free tools can tell you which one in a few minutes.
A slow website loses visitors. People don't wait long for a page that seems stuck, especially on a phone. Speed also matters to search engines as part of how they judge page experience. The good news is that most slow sites are slow for a handful of common reasons, and you can diagnose them with free tools on Free Micro Apps.
Part of the answer is that pages have grown. The HTTP Archive Web Almanac 2024 found that the median mobile page weighs about 2,311 KB, that the median mobile page grew by 357% over ten years, and that 92% of pages load third-party resources. The same report found that text compression was used correctly on only 70% of desktop homepages, so turning on compression is often a quick win.
Pick two or three important pages, such as your homepage, a top product or service page and a popular article. Test each one so you have a baseline to compare against later.
Write down the results. Test more than once, since results vary a little from run to run.
Page weight is one of the simplest and most telling numbers. A page that downloads several megabytes is going to be slow on a mobile connection no matter what else you do.
If your page is heavy, the next question is: heavy with what? Usually it's one of these:
Images are the most common cause of heavy pages. Typical problems:
Fixes: resize images to the largest size they're actually displayed at, compress them, and use modern formats where your platform supports them. Many platforms and plugins can do this automatically for new uploads.
As a bonus, photos often carry hidden metadata such as camera details and sometimes location. The EXIF Data Viewer shows what's embedded, and the EXIF Data Remover strips it, which is good for privacy and trims a little weight.
Videos embedded directly on a page can be very heavy. Using a video platform's embed, and making sure videos don't autoplay or preload unnecessarily, usually helps.
Each custom font and weight is another file to download. Using fewer font families and weights is an easy saving.
Many slow sites aren't slow because of their own content but because of everything bolted on: chat widgets, social media embeds, multiple analytics tools, ad scripts, popups, sliders and plugins.
To investigate:
Removing a single unused plugin or widget can make a bigger difference than hours of fine-tuning.
The Code to Text Ratio Checker is another rough signal. A very low ratio means the page has lots of code relative to its visible content, which sometimes points to bloat.
If the page is light but still slow to start loading, the server may be the bottleneck.
Signs of a server problem include a long wait before anything appears, slow performance at busy times, or consistently slow responses even for simple pages. Possible fixes include enabling caching, using a content delivery network (CDN), upgrading your hosting plan or moving to a better host.
Work from the biggest, easiest wins to the smallest:
Re-test the same pages with the same tools and compare against your baseline. If a change didn't help, undo it or move on. Keep notes, because speed tends to drift over time as new content and plugins are added.
Test on mobile results, not just desktop. Mobile devices are often slower and on slower connections, so problems show up more clearly. The Screen Resolution Simulator also helps you see how your layout behaves at different screen sizes.
Most sites get noticeably faster with just the first two or three fixes. If you'd like help, contact us.
Oversized images are one of the most frequent causes, followed by slow server response and too many third-party scripts.
Yes. Slow server response time often points to hosting or backend issues, especially on cheap shared hosting.
Use a free page size checker to see how large the page is and what's adding weight.
Faster is better. Google's Core Web Vitals treat a Largest Contentful Paint of 2.5 seconds or less as good.
Caching helps response time, but it won't fix oversized images or heavy scripts on its own.
