You don’t need me to tell you that page speed is important.
Page speed’s importance is one of the reasons you see all those massive, complicated posts on how to speed up WordPress.
WOT Cache is a performance plugin that aims to make that “speed up” process a bit simpler by adding a variety of performance tweaks to your WordPress site like:
- Page and browser caching
- Image optimization
- Removing render blocking content
- Removing query strings
- Google Fonts optimization
- File compression
And in my WOT Cache review, I’m going to attempt to figure out just how much all those tweaks that WOT Cache makes can speed up your WordPress site.
WOT Cache Review: The Full Feature List
If you’ve ever used the Google PageSpeed Insights tool, you’ll probably be familiar with many of WOT Cache’s features (that’s a good thing!). Here’s everything that WOT Cache can help you do:
- Page caching – by itself, page caching usually dramatically improves most WordPress sites’ page load times.
- Browser caching – lets you store commonly used static assets (like your logo) on a user’s local computer.
- Image optimization – compresses your images to reduce their file sizes.
- GZIP compression – another way to reduce the file size of a page.
- Remove render blocking content – this is a Google PageSpeed Insights recommendation that many people struggle with.
- Google Fonts optimization – asynchronously loads Google Fonts files.
- Database optimization – cleans your database to remove bloat.
- Lazy load – lets you (optionally) lazy load images and videos.
As you may have noticed, there’s significantly more depth there than your average caching plugin. How much does that actually help your site’s page load times? Let’s find out…
Hands-on With WOT Cache: Real Testing Data
To test how well WOT Cache can speed up a site, I’m going to put it through the ultimate gauntlet:
A $10 (yearly) NameCheap shared server
Yup – my test site is on literally the cheapest WordPress hosting I could find, so WOT Cache certainly has a tough job ahead.

But before I get to the actual testing data, let me give you a quick tour of the WOT Cache interface…
A Look At The WOT Cache Interface
Once you activate WOT Cache, all of the settings are contained in various tabs of the Settings → WOT Cache interface:
There’s a good bit of stuff to configure here, but one nice thing is that you can quickly configure a bunch of settings by using the Presets tab:
Here’s generally what each tab lets you do:
- HTML/CSS – minify HTML/CSS, exclude certain CSS, combine/async CSS, Async Google Fonts, remove query strings, exclude specific pages.
- Lazy Load – lets you enable lazy loading as well as exclude certain pages and/or exclude mobile traffic.
- Image Optimization – choose desired image quality and whether or not to resize image dimensions.
- Cache – configure when to clear the cache and exclude certain pages from the cache.
- Database – clear all extraneous content or just specific content.
If you want it, WOT Cache gives you a good deal of control over your site. But if you’re not sure what the settings mean, you can always just import the General preset and call it a day. That’s what I’ll be doing for my test site!
WOT Cache Performance Test – The BEFORE
Ok, time to actually see how WOT Cache performs in the real world.
Here are some more details on the site that I’m going to test WOT Cache on:
- Hosted on the cheapest WordPress hosting in existence ($10 per year Namecheap hosting)
- Using the Elementor Homepage – Fitness template for the homepage (with Elementor Canvas)
- Beyond Elementor, there are no other active plugins
Here’s how my test site performed in GTmetrix before using WOT Cache. The 0.96 MB page with 44 requests loaded in 2.6 seconds:
Honestly, that’s a bit faster than I thought it would be – so kudos to cheap Namecheap hosting!
To see how it performed under load, here’s how it did in Load Impact with 50 virtual users:
At the beginning, it hovered around ~2.5 second load times before eventually peaking at 3.33 seconds around the 45 user mark.
WOT Cache Performance Test – The AFTER
To remove as much user error as possible from my After test, I’m going to use the General preset for WOT Cache.
Beyond importing that preset, I won’t make any manual changes.
So in a nutshell, this is what WOT Cache can do for your site out of the box without any tinkering.
After doing that, here’s how my test site fared.
In GTmetrix, my page shrank to 669 KB and only has 40 external requests. It now loads in just 1.3 seconds, which is a 50% reduction in page load times:
Additionally, you can see that my test site now gets a 100% PageSpeed score.
What I’m even more interested in is whether these improvements translate into improved performance under load. Here’s how my test site fared in a 50 user Load Impact test after installing and configuring WOT Cache:
This time, there was no spike as traffic increased. Instead, my site’s page load times actually went down as virtual users increased.
My test site averaged around 1.4 second load times with a peak of 1.65 seconds, which is a big improvement.
For an easy comparison, here’s the before and after in table form:
|GTmetrix||Load impact Avg.||Load Impact Peak|
|BEFORE WOT Cache||2.6 seconds||~2.5 seconds||3.33 seconds|
|AFTER WOT Cache||1.3 seconds||~1.4 seconds||1.65 seconds|
In a nutshell, my test site not only loaded ~50% faster, it was also more stable under a high traffic situation.
How Much Does WOT Cache Cost?
WOT Cache is exclusively a premium plugin. It also has quite simple pricing – WOT Cache costs $32 for a single site license. That’s it!
Final Thoughts WOT Cache
It’s always hard for me to recommend a premium caching plugin simply because there are so many great free caching options out there.
With that being said, as I tried to make made clear in the intro, WOT Cache has a lot more going on than just caching. Those extra features are what I think can make WOT Cache worth paying for. That is, you’re getting a comprehensive performance plugin, rather than just a caching plugin.
My test site is a pretty good example of what this comprehensive approach can achieve.
So, if you want a comprehensive, easy way to speed up your WordPress site in a variety of different ways, paying $32 for WOT Cache is a super convenient way to do that.
