25 WordPress Speed Optimization Plugins For Speeding Up Your Website In 2020 (Same Ones I Used To Get 100% GTmetrix Scores)

Home » WordPress Speed » 25 WordPress Speed Optimization Plugins For Speeding Up Your Website In 2020 (Same Ones I Used To Get 100% GTmetrix Scores)

Need a solid list of WordPress speed optimization plugins?

These are the same speed plugins I used to get 100% GTmetrix scores on my homepage and most of my posts. They’re a collection of plugins I use myself and popular plugins in Facebook Groups. I do WordPress speed optimization for a living – so I geek pretty hard on the plugins!

This is not a typical list of cache plugins: I dive into advanced plugins like selectively plugin disabling, browser resource hints for external scripts, hosting things locally, and bloat removal.

ps. If you join the WordPress Speed Up Facebook Group they have a list of 60+ recommended WordPress Speed Up Tools and useful links. But I did try to include the important ones here :)




1. WP Rocket

WP Rocket was rated the #1 cache plugin in most Facebook polls.

That’s because it comes with more features than any other cache plugin. This means better GTmetrix results and less plugins needed on your site. Otherwise, with other cache plugins, you would need to research which features it doesn’t include, then install these extra plugins if it doesn’t support them. If you’re like me, you want to use 1 plugin (WP Rocket) for everything.

  • Lazy load images/videos (built-in to WP Rocket, or use WP YouTube Lyte)
  • Host Google Analytics locally (built-in to WP Rocket, or use CAOS For Analytics)
  • Host Google Fonts locally (built-in to WP Rocket, or use CAOS For Fonts, or SHGF)
  • Integration with Cloudflare + other CDNs (built-in to WP Rocket, or use CDN Enabler)

Get 10% off WP Rocket by signing up for their email list on their coupons page. Then check my recommended WP Rocket settings for optimal GTmetrix scores/load times.

2. SG Optimizer


SG Optimizer only works if you’re on SiteGround’s hosting.

On a demo website, I tested SG Optimizer with a fresh installation of Astra’s Outdoor Adventure theme on SiteGround’s GrowBig plan and got a 1s load time with 99%/94% GTmetrix scores. If I used a CDN, my GTmetrix scores would have been exactly 99%/100%.

Since SiteGround’s big update to SG Optimizer, it’s now comparable to WP Rocket. It also uses server-side caching and binaries which is faster and more efficient than the file-based caching by other cache plugins (including WP Rocket). If you’re on SiteGround, I would definitely use it.

See my recommended SG Optimizer settings to learn how to configure SG Optimizer.

SG Optimizer Features

  • Caching (static, dynamic, memcached)
  • Minify & combine HTML, CSS, JS
  • Gzip compression
  • Database Cleanup
  • Heartbeat Control
  • Prefetch External Domains
  • PHP version selection
  • Optimize Google Fonts
  • Defer render-blocking JS
  • Compress new + existing images
  • Lazy load images, videos, iframes, Gravatars, thumbnails, widgets, mobile

Features SG Optimizer Lacks – CDN URL, bloat removal, hosting fonts + analytics locally.


3. Perfmatters

Kinsta’s Perfmatters is the ultimate bloat removal plugin.

A few notable features include decreasing the autosave interval, limiting post revisions, disabling heartbeat and pingbacks, prefetching + preconnecting fonts and third party scripts, and optimizing WooCommerce scripts, styles, and cart fragments. It basically takes care of the last 10% of WordPress speed optimization with features WP Rocket/SG Optimizer don’t have.

perfmatters features

Perfmatters includes a script manager for selectively disabling scripts/plugins on specific content (same thing as Asset CleanUp). Some plugins load across your entire site even when they’re not being used. By selectively disabling plugins, you will reduce page sizes and make them load faster. There’s also a Regex option to better control where plugins are being loaded.


  • Disable slider plugin on pages not using sliders
  • Disable rich snippets plugin on pages not using rich snippets
  • Disable contact form plugin on pages not using contact forms
  • Disable affiliate link management plugin on pages not using aff links
  • Disable social sharing plugin on all pages (since it’s usually for blog posts)



4. Asset CleanUp

Same thing as the Perfmatters script manager (lets you selectively disable scripts/plugins) only Asset CleanUp doesn’t have bloat removal options, but it is free. Plugin Organizer and Plugin Load Filter are similar, but AssetCleanUp has great reviews and is what most people are using.

Asset CleanUp Check All


5. TinyPNG

Compresses images to get 100% for the “optimize images” item in GTmetrix.

I have tried Imagify, ShortPixel, and other image optimization plugins but they all resulted in a loss in quality even when the “lossless” option was selected. Slowly but surely, I am redoing these images in TinyPNG. I see barely any quality loss which I can’t say for the other plugins.



6. WP-Optimize

A big difference between WP-Optimize and WP Rocket’s database cleanup feature, is that WP-Optimize lets you delete old plugin tables.

Both plugins let you delete trash (trashed posts, spam posts, post revisions, transients) and optimize your database tables. But WP-Optimize lets you view your individual database tables and delete tables left behind by old (not installed) plugins. If you don’t plan on using these plugins again, you can delete their tables since they often leave behind pre-configured settings.


WP Rocket does the same thing, only it doesn’t let you delete old plugin tables:



7. WP YouTube Lyte

Lazy loads videos by inserting responsive “Lite YouTube Embeds” which only calls the “fat” YouTube player when the play button is clicked. Videos take the longest time to load by far. Just to give you an idea, my W3 Total Cache tutorial only has 2 videos, but when I lazy load them that post’s load time went from 5s to 1.5s. It has the same function as light video embeds.

If using WP Rocket, you can simply lazy load videos and replace iframes with a preview image.



8. Heartbeat Control

The WordPress heartbeat API consumes resources by sending you real-time plugin notifications, when other users are editing a post, and so on. 99% of people should disable it.


WP Rocket and Perfmatters also let you disable it, or add this code to your functions.php file.

add_action( 'init', 'stop_heartbeat', 1 );
function stop_heartbeat() {


9. Pre* Party Resource Hints

Supports browser resources hints which can make fonts and scripts load faster.

WP Rocket already supports prefetch and preconnect, otherwise you can use Pre* Party Resource Hints. Third party scripts can be found in the “reduce DNS lookups” section of your GTmetrix report or shown as “reduce the impact of third party code” in PageSpeed Insights.

These can be Gravatars, Google Analytics, Maps, Tag Manager, AdSense, embedded videos, or any third party request generated on your website. You’ll want to prefetch these (Luke created a nice list of common domains to prefetch). And if you’re using Google Fonts or Font Awesome, grab your font URLs from the GTmetrix Waterfall tab and add them to the preconnect section.



10. OMGF | Host Google Fonts Locally

OMGF can fix Google Font related errors by downloading all your Google Fonts (using the Google Fonts Helper API) and generating a stylesheet for them. You will need to configure the settings to serve fonts from your CDN and select the folders to save font files to. While some plugins like WP Rocket and SG Optimizer already optimize fonts, OMGF can often yield better load times especially when images are served from a CDN. Self-Hosted Google Fonts is similar.


What it looks like:


Tip: if using external fonts, be minimal with the number of fonts (and font weights) you choose. If for some reason this plugin doesn’t fix errors, I have a guide for hosting Google Fonts locally.


11. CAOS | Host Google Analytics Locally

Leverage Brower Caching Google Analytics

CAOS fixes the leverage browser caching item in GTmetrix by hosting Google Analytics locally. Install the plugin, enter your Tracking-ID, and CAOS will add the Tracking Code to the header or footer. But if you’re using WP Rocket or Perfmatters, these already have this functionality.



12. wpDiscuz

Why is wpDiscuz in my list of WordPress speed plugins?

Because with wpDiscuz, I get an awesome comment plugin on my blog with virtually no expense to my GTmetrix report. This is usually not the case with other commenting plugins. Go to your wpDiscuz settings and use the tweaks below which should make the plugin load faster.

Recommended settings to speed up wpDiscuz:

Comment Thread Displaying → initiate AJAX loading after page and lazy load comment.


General → disable “use WordPress native AJAX functions” and enable combine/minify JS/CSS.


Styles And Colors → disable “load font awesome CSS lib.”



13. Flying Scripts


This plugin helps you optimize third party scripts found in GTmetrix (reduce DNS lookups) and PageSpeed Insights (minimize third party scripts).

It delays loading of JavaScript until the timeout period you set in the plugin. For example, you can delay loading your comments plugin and Gravatars for 3 seconds which can significantly speed up initial load times. In fact, Flying Scripts is the only plugin that let me show Gravatars without them affecting GTmetrix. It is definitely one of my favorite WordPress speed plugins.



14. WP User Avatar

The blank default Gravatar can still create errors in GTmetrix.

If you don’t want it to, install the WP User Avatar plugin which hosts the default Gravatar locally. Upload your own optimized Gravatar image (ideally a 50×50 pixel compressed image).



15. CDN Enabler

CDN Enabler helps you set up a CDN (content delivery network). This does not work with Cloudflare which requires changing nameservers, while CDN enabler is specifically for StackPath, KeyCDN, and other CDNs that provide a CDN URL. First, sign up for a CDN (I use StackPath) then enter your CDN URL into the CDN Enabler plugin. See instructions below:

Step 1: Sign up for a CDN (I use StackPath who has 34 data centers) and create a CDN site.

Step 2: Grab Your CDN URL:


Step 3: Enter your CDN URL into CDN Enabler, then configure the settings:



16. Breeze By Cloudways

Breeze is only if you’re using Cloudways hosting.

It has a long way to go if they want to catch up to SG Optimizer or WP Rocket, and I would personally use WP Rocket instead as it lacks many features (probably why it doesn’t have the best ratings). While I highly recommend Cloudways hosting, I can’t recommend Breeze yet.


Cloudways Breeze plugin isn’t great, their hosting is.



17. Autoptimize

Optimizes HTML, CSS, and JavaScript. You don’t need Autoptimize unless you’re hosted on GoDaddy, WP Engine, or any host who blacklists cache plugins, since WP Rocket and most cache plugins optimize the code for you. But while GoDaddy and WP Engine’s built-in caching might be fine, it doesn’t optimize HTML/CSS/JS. That’s where Autoptimize comes into play.



18. WP Fastest Cache

WP Fastest Cache is usually rated one of the top free cache plugins and is easy to configure. However, it lacks quite a few features and if you want them, you’ll need to upgrade to the premium version, in which case you’ll be better off with WP Rocket. I have a configuration tutorial on the WP Fastest Cache settings as well as W3 Total Cache and WP Super Cache.



19. ToolKit For Elementor

ToolKit does a little bit of everything (minification, combination, font optimization, lazy load, bloat removal, gzip, browser caching, expires headers), but it doesn’t do everything. You’ll be better off using WP Rocket combined with Perfmatters. One thing I like about ToolKit is the option to disable unused widgets in Elementor, WordPress, and in the WordPress dashboard.



20. AMP For WP

I was using AMP, but I ultimately disabled it and now I don’t. But if you want to add AMP (accelerated mobile pages) to WordPress, this is one of the most highly rated AMP plugins since it has lots of customization options. One of the frustrating parts about AMP is that it strips some of your design elements, so you want to make sure the mobile pages still look nice.

Warning: AMP can sometimes decrease mobile conversions. Read Kinsta’s study on how their conversions dropped 59% when using AMP. I ultimately decided against it.


This plugin has tons of settings for customizing mobile pages:



21. Query Monitor

Find your slow loading plugins, queries, scripts, and other elements that take longest to load. Make sure you delete it when you’re done, since Query Monitor can cause high CPU in itself.

Query Monitor Slow Plugins

You can also use GTmetrix Waterfall to find your slowest plugins:

Slow WordPress Plugin


22. Display PHP Version

Display PHP Version simply shows which PHP version you’re running. Faster PHP versions = faster load times, so be sure to login to your hosting account and use the latest PHP version.



23. GTMetrix For WordPress

The GTmetrix WordPress plugin monitors your load times and PageSpeed + YSlow scores, then sends you a report directly in your WordPress dashboard, or through scheduled email reports.





24. WP Hosting Performance Check

Shows overall performance of hosting and whether your technology (PHP, MySQL, WordPress versions) is running slow, in which case it should be updated. It also shows your slowest pages.




Or simply check your server response time in PageSpeed Insights.

Reduce Server Response Time Under 200ms


25. Better Search Replace

If you see minimize redirects in your GTmetrix report, this usually means you changed the WWW or HTTPS version of your site, but didn’t change your links to reflect the new version.


Instead of fixing all your links manually, use the Better Search And Replace plugin to update them in bulk. It can also be helpful for fixing broken links, or even bulk updating links/images which appear on multiple pages/posts. Better Search Replace can be an enormous time saver.

Other Notable Tools / Resources

No speed plugin can fix a slow server response time in PageSpeed Insights; it’s your hosting.


Cloudways – #1 host in recent Facebook polls. It used to be SiteGround, but their TTFB isn’t good anymore, they increased prices, and have strict CPU limits. Cloudways is cloud hosting, monthly pricing, no strict CPU limits, and is much faster than SiteGround, GoDaddy, or EIG brands like Bluehost and HostGator. Join some Facebook Groups like WP Speed Matters or WP Hosting and do your own research – anyone who knows anything will recommend Cloudways.

Avoid These Hosting Companies

Why I Use Cloudways

  • GTmetrix report speaks for itself.
  • TTFB is under 200ms in my GTmetrix Timings report.
  • Server response times are under 300ms in PageSpeed Insights.
  • Posts like this (ones that are very long) still load in under 2s.
  • It can handle resource-hungry plugins (shared hosting can’t).
  • DigitalOcean is recommended in WordPress optimization guide.
  • They’re highly recommended in Facebook Groups, polls, conversations.
  • Out of 15+ popular hosts, they were the fastest in my Pingdom speed test.
  • They do free trials, free migrations, and their community manager is very helpful.

I even made a video where I installed the same Astra Starter Site using 15+ different hosting companies and tested their load times (for example, visit cwdoserver.com or stgrndserver.com and click through the site to test speeds of Cloudways DigitalOcean vs. SiteGround GrowBig). Or check out these other sites that use Bluehost, HostGator, or GoDaddy. Here are the results.

Affiliate Disclaimer – if you sign up for Cloudways using my affiliate link or use promo code OMM25, this saves you money and credits me the sale which I really appreciate. I donate quite a bit to charity ($6,000 to GoFundMe so far) and only recommend the fastest, best host based on real evidence: speed tests, polls, my results, other migration results, and conversations from 20+ FB Groups I’m in. Thank you so much if you use it.

Cloudflare – free CDN and speed/security service which mirrors your site (and offloads resources) on over 200+ data centers. Integrates with most cache plugins with options to use aggressive minification, Railgun, and hotlinking. All my cache plugin tutorials include Cloudflare setup instructions and don’t forget to set up page rules for your WordPress site.

StackPath – paid CDN which adds 30+ additional data centers around the world (more data centers = faster content delivery), reducing the distance between your website/visitors – a recommendation in the WordPress optimization guide. $10/month with a free 30-day trial.

Pingdom – most accurate tool for measuring load times according to WP Rocket, though GTmetrix has better recommendations for actually optimizing your site, in my humble opinion.

GTmetrix – good for identifying images that need to be optimized using the 3 methods: serving scaled images (resizing them), specifying images dimensions in the HTML/CSS, and optimizing images (lossless compression). GTmetrix recently switched to a fully loaded time metric which shows a longer load time than previously. Their waterfall tab measures individual slow loading elements, and if your time to first byte is long that indicates your hosting is slow.

Google PageSpeed Insights – most recommendations can be ignored but it’s good for measuring server response time which Google recommends <200ms or your hosting is slow.

Pronaya (My WordPress Speed Optimizer) – you can hire my WordPress speed optimizer on freelancer.com who I’ve been working with for 5 years and we’ve optimized multiple sites to load 500% faster. His name is Pronaya, he’s $40/hour and has a perfect 5/5 star review with 19 reviews (just sign up for a Freelancer account and search for user BDKAMOL). If you think I’m good at speed optimization, Pronaya is way better. I’ve also been working with Usama (his username is I333) who is quite cheaper but is also amazing with 4.9/5 stars and 375+ reviews.
