Agreed! Speed is not the only criteria to measure website performance. There are primarily three criteria that should be kept in mind when creating a high performance website: speed, security and content (images & videos). In my other posts where I list down Top CDN providers, you can look at various criteria that you should keep in mind to create a high performance WordPress website.

Like you, I do a little bit of evaluation and research on all things before starting or purchasing. I did the same recently before creating (blog). I researched several cheap WordPress hosting providers for 2021 on their offerings, reviews by other websites and users, promotions, and real-time support.

After downloading and trying almost 40 different WordPress speed Optimization plugins for my website, I finally selected 5 wordpress speed plugins to reduce page load times and get GTmetrix 100% score as well as 100 Google Pagespeed score.

WP Rocket

wp-rocket is the best wordpress speed optimization plugin

WP Rocket, along with WP Fastest cache, is the best WordPress speed optimization plugin to speed up my website for 100% gtmetrix score. There are several others WordPress caching plugins like WP Super cache, W3 Total Cache. I’m not denying that they are good. I tried them all but the best one I liked to reduce page load times were free version of WP Fastest Cache and premium version of WP Rocket.

Features of WP Rocket:

  • Minify CSS, HTML and JavaScript
  • Combine CSS, HTML and JavaScript
  • WordPress Caching – possible to enable caching for mobile users and logged-in users.
  • Set cache lifespan as per your requirement
  • Cache preload. You can also preload links, fonts, DNS requests
  • Other advanced caching rules like other best wordpress plugins for speed
  • Image lazy load. Iframe and videos lazy load.
  • Load deferred JavaScript *
  • Delay JavaScript execution time – don’t load JS until user interaction
  • Database optimization and Database / Transients cleanup
  • CDN integration
  • Direct Cloudflare integration
  • Google Analytics integration to host Google Analytics code on your own site.

* Note that delaying JavaScript execution time can have a huge impact on website loading, page load times, Google PageSpeed scores, GTMetrix scores. This helps eliminate render-blocking JS and help improve website load time.

WP-rocket is like a powerful combination of several WordPress speed optimization plugins acting together. Its a beast having 3+ WordPress caching plugins performance.

However, WP-rocket alone acts as a one-stop-shop best WordPress speed optimizer for all the Features mentioned above.

Image optimization is a PAID in-built feature for image optimization in WP-rocket through integration with IMAGIFY. The same company has created IMAGIFY for best-in-class image optimization. You can compress images to speed up your website for 100% gtmetrix score while maintaining high image quality.

WP Fastest cache is also amongst the best wordpress plugins for speed. It also has the same offerings. I personally tried it and consider it as an awesome WordPress speed optimization plugin. But its free offerings are a bit limited when compared to WP Rocket. WP Fastest cache has Paid services for CDN integration, database cleanup, image optimization.

Following is a brilliant article (external to on comparison of the two best wordpress speed optimization plugins: WP Rocket and WP Fastest Cache.

WP Fastest Cache vs WP Rocket – The best WordPress caching plugins

I tried WP Rocket & WP Fastest cache as well as WP Super cache & WP Total Cache. I finally decided to stay with WP Rocket premium version + Cloudflare FREE CDN + Robin Image optimizer FREE version.

Asset CleanUp: Page Speed Booster

Mos of the time, if you are using WordPress plugins & themes, then all plugins, CSS and JavaScript run together on the same page. However, we might not need to use all of those plugins, CSS and JavaScript on that particular page. To reduce page load times and for WordPress speed optimization, you should make the HTML source code cleaner and prevent those plugins, CSS, JavaScript from loading.

asset cleanup best plugin to optimize wordpress

If you use a plugin for forms or image gallery and so on, it will load its plugins, CSS, JavaScript files in every page of your website. This will instead have a drastic effect on your intention to reduce page load time via WordPress plugins. The best wordpress plugins for speed should make sure that they are loaded only on the page where it’s needed. For instance, I have compared various image optimization plugins and in the later half of this post, I have used a Before After image plugin to show real matches between 3 images that I optimized using different WordPress image optimization plugins.

Asset CleanUp is one such WordPress speed optimization plugin that helps you avoid all that mess. It scans your page, detects and displays all the plugins, CSS, JavaScript files that are loaded on a specific page or the complete website. You have to just select the plugins, CSS, JavaScript files that you don’t want to load. In this way you load only the scripts that are needed, thereby reducing the bloat and making your WordPress website faster. All in all, Asset cleanup is one of the best WordPress caching plugins.

Asset CleanUp Features

  • Eliminate render-blocking resources by unloading useless CSS/JS
  • Option to delay or preload CSS, JavaScript, Fonts files depending on your requirement
  • Minify and combine CSS, JavaScript files
  • Defer combined JavaScript files by applying “defer” attribute to the SCRIPT tags
  • Site-wide removal for Emojis, Dashicons for guest users and Comment Reply if they are not used
  • Reduce HTML code, GZIP compression
  • Combine all Google Font requests and save round trips to the server
  • Preload Google Font Files
  • Preload local font files – no need for other best wordpress plugins for speed
  • remove meta tags, unused links, HTML comments from the head, body and footer tags of the website

Especially for fixing page slowness issues as reported by Google PageSpeed or GTMetrix, you can choose from 3 types of script delivery:

  • Render-blocking,
  • Asynchronous via Web Font Loader (webfont.js),
  • Asynchronous by preloading the CSS stylesheet

Robin image optimizer

Robin image optimizer is a fantastic image optimizer and compression WordPress plugin. It can optimize / compress with almost no loss in quality. In the company’s own words it is exactly 80% without any loss of quality. You should always use the best image compression wordpress plugins for speed improvement, unless you optimize all images before upload.

I will undoubtedly put Robin image optimizer in my arsenal of best WordPress speed plugins. It uses an intelligent optimization mode to reduce the size of JPG and PNG images in both free and paid versions. If your website is full of images, your website will become 50% faster.

For FREE version, the only restriction is the image size – it shouldn’t be greater than 5 MB.

It can resize your images on demand through the media library or by the click of a button. It also optimizes on the fly as soon as some image is uploaded to the media library.

The paid version has 3 more features.

  • Optimization at Google PageSpeed level
  • Optimization in folders other than upload folder
  • Conversion to WebP

The settings are extremely user-friendly and shown in just 1 page unlike other plugins where settings are distributed over several pages.

I have personally generated and compared the image quality of Lossless and Lossy images from Smush, Imagify, Robin optimizer, HighCompress AI,, ShortPixel and an image from Image Regenerate & Select Crop plugin at 65-level quality.

You can yourself evaluate compressed images from top image optimization and image compression plugins using the 2 sliders shown below.

All following images are optimized to Lossless quality from Smush, Robin, and Image Regenerate & Select Crop. They are around 150 Kb each. I have generated an 82-level quality image (equivalent to lossless) from Image Regenerate & Select Crop plugin

Smush vs. Robin vs. Image generate & Crop is a blog where images play an important role, but the text content is where visitors really focus. Any popular information blog contains 70% to 80% text and 10% to 20% images, unless the blog is on art, media or some portfolio. It’s generally difficult for the blog reader’s eyes to compare between the image quality of popular image optimization plugins.

UpdraftPlus backup

Why do I need website Backups? Why do they fall under essential WordPress speed optimization plugins? These 2 questions might pop-up on your mind if you plan to start a small blogging or hobby website.

updraft best wordpress speed optimizer

Backups are the first level of security for any WordPress site. According to research, data loss and downtime cost global economic losses of $1.7 trillion each year. All websites are vulnerable to WordPress corruption, data loss and security threats.

  • Hackers may steal and destroy your data if your website is hacked.
  • Due to wrong plugin installation or code tampering, your WordPress installation might get corrupt and become irrecoverable or very expensive to recover.
  • Your hosting provider can lose your data unintentionally or due to shut-down
  • Your host might terminate your account and delete all your data for any reason. However, this will almost never happen if you choose popular hosting providers with good standing.

Apart from these, there are many other scenarios where you could end up losing valuable data or your entire website. So, its always in your best interest to protect your website against these threats. Regular backing up of your WordPress website is the only answer!

Sadly, WordPress does not give you a built-in backup solution. However, you can find several WordPress backup plugins on WordPress plugin manager. Almost all of them allow you to automatically backup and restore your WordPress site.

As per my experience, UpdraftPlus is one of the best WordPress backup plugins. It not only backs up your data and your entire website on your hosting space but also exports the backups to cloud storage like Dropbox, Google Drive. Even in the FREE version, it allows you to back up manually on-demand as well as set up automatic backup schedules. Moreover, in case something bad happens, you can use it to restore your WordPress site from BackUp.

I suggest you use this backup plugin along with the best wordpress plugins for speed improvement to see your website load fast and rank higher.

Updraft Premium features

The free version of UpdraftPlus is already really powerful. However, if you need more features and options you can purchase the Premium version. Few of the features of UpdraftPlus Premium (click to get a trial) are as follows:

  • Incremental backups

Considering that UpdraftPlus premium version has so many extra features, you may like to try the premium version of Updraftplus.

Wordfence security and firewall

Over last year itself, data breaches have exposed more than 4.1 billion records. As per recent IBM research, the average cost of a data breach is $3.9 million. Therefore, every website, large or small, needs to ensure high security, not just high performance.

Wordfence is one of the most popular security plugins for WordPress websites. It has a long list of features like:

  • Full-fledged firewall – you can rate-limit or block IP addresses, Bots and Google crawlers.
  • Brute-force (login) attack protection. A premium account holder gets real-time IP address blacklist feature as well.
  • Login security – secure your login to WordPress admin section. It has 2FA and QR code scan built-in.
  • Wordfence alerts – Another useful benefit is the daily scans feature. You get an email about any suspicious activity or any notification about other possible security threats like required plugin updates.
  • Malware scanning – you can set your own customized scan or use a standard scan

Security plugins are not directly termed as WordPress speed optimization plugins for that matter. However, they help you in keeping your site secure and in preventing bad bots touching your site and consuming your server resources, especially if you are on shared hosting. Even the best wordpress plugins for speed improvement will not be able to speed up your website in case of a hacked website.

wordfence best wordpress plugin to speed up your website

I tried using a few security plugins. I found Wordfence to be simple, easy to set up and secure enough. The FREE version has all basic features needed for a secure website. The premium upgrade has several other features, but you generally don’t need those extra to secure a small website or blog.

As a free Wordfence user, you will be using the Community version of the Threat Defense Feed. Premium users however are protected by additional firewall rules and malware signatures.

A few extra Best WordPress plugins for fast website loading times

Archivarix External Images Importer

Archivarix External Images Importer plugin imports images from external web sources. It is useful when you have your images posted on an external website and want to download all your images from that external source to your hosting. This plugin will scan your posts and pages for images from external URLs. On a click of a button, if you desire it will import all the images from there to your new hosting provider. It’s quite possible that the images you are referring to you in your posts are from an external slow website. This plugin functions as the best WordPress speed plugin useful in this clear way.

external images import to increase website speed wordpress plugin

If the image is not available or deleted from the original source, this plugin downloads a copy of it from the Web Archive.

It helps you host stuff locally instead of on other external websites. You may have blogs on multiple blogging platforms or multiple hosting websites. In every blog it is quite possible to refer to a common image. The problem with this set-up is that if the main website goes down, all your other posts or pages referring to the images on that site will be image-less. Even with the best WordPress speed optimizer plugins, you will feel that it’s best to have all your images on your post’s internal space.

It also helps in helps improve your website load times because the images are sourced from your webspace instead of some external domain.

I don’t know why top reviewers do not classify this plugin under he best wordpress plugins for speed improvement. In my view, this is an utmost important plugin if you have a host of websites using images from different sources, not just your own websites.

WPS Hide Login

WPS Hide Login helps you to easily and safely change the WordPress login page address to a custom address. It will certainly not rename or change files in core and not add or rewrite any rules. It merely intercepts page requests and works on any WordPress website. The wp-admin directory and wp-login.php page become inaccessible, so you need to bookmark or keep in mind the new URL. Deactivating this plugin brings your website back specifically to the state it had been before.

Hiding your WordPress login will only stop amateurs and not robots or hackers. Someone who actively breaks into websites will undoubtedly be able to locate the login page on your website. Therefore, consider this plugin as a supplement to Wordfence or other security elements, but not an alternative to protect your website.

Really Simple SSL – best WordPress plugin to secure your website

Really Simple SSL automatically detects your settings and configures your website to run over HTTPS. The insecure content is fixed by replacing all http:// URL’s with https://, except hyperlinks to other domains. This plugin does not provide you an SSL certificate. You have to use the SSL given by your hosting provider, your CDN service or your own Client certificate. The plugin handles most issues that WordPress has with SSL. You can also enable a .htaccess redirect.

SSL plugins are not WordPress caching plugins and don’t fall under the ambit of WordPress speed optimization plugins per say. However, they help you have better performance because of the level of added security, which helps a browser exclude detailed security checks, thereby enabling your website to load faster.

In this way, Really Simple SSL plugin is truly a WordPress speed optimizer after converting your website to an HTTPS one with an SSL certificate. Remember that GTmetrix 100 score considers SSL as a prominent factor as well.

Combining it with the best WordPress speed plugin like WP-Rocket will certainly help reduce page load times of your website and get 100/100 pagespeed scores.

SSL plugin how to load my website faster using wordpress plugins

Really Simple SSL has a premium version, but I feel the FREE version is itself full of many useful features. I would recommend your small website or blog to start with the FREE version first. Later you may see if you really need the premium one.

It helps you improve website security by enabling HTTP Strict Transport Security and HSTS preload while protecting your domain against attacks.

The premium version comes with 3 enhanced features as shown in the image below.

If you want to enable HSTS and security headers, then you must take the premium version of Really Simple SSL.

Frequently Asked Questions (FAQ)

Can I use a combination of Asset cleanup and WP rocket?

Certainly. Using Asset Cleanup and WP-rocket together t is the best Option. I myself do and recommend using WP-rocket with Asset cleanup for optimal settings. Both of them are best WordPress speed optimizers. You may also top up your setup with adding some expert configuration and settings from Asset Clean up. You will definitely achieve top-notch A-grade GTmetrix 100 level performance.
Both these are the best wordpress plugins for speed improvement. Asset Cleanup and Wp rocket automatically detect and pair with each other. For example, if you have installed WP-rocket and enabled Combine CSS/JavaScript options, then Asset cleanup will automatically disable Combine CSS/JS options for you citing that they are already taken by WP-rocket.

What is lossy vs lossless compression?

Most image files are often huge and average global internet speed is not that fast as to load image-heavy websites really fast. So, it is important that all images are somehow compressed to be properly used on a website.
Average internet speeds in different countries all over the world.

There are many algorithms used for image compression. Generally all algorithms are divided into two distinct categories: lossless or lossy compression.
Lossy compression algorithms reduce file size by discarding the less important information. For example, reducing the numbers of colours in an image while keeping the brightness in-tact. This can result in a small loss of quality of an image or sound file. JPEG is an example of lossy compression format. It offers much higher compression rate than PNG with decrease in quality.
Lossless regenerates the image with the lowest possible number of bits without loss of any information. The original data is then perfectly reconstructed from the compressed data. However, no lossless compression algorithm can efficiently compress all data in an image. That’s why lossless compressed images are not much smaller in size. They however are much higher in quality that lossy optimized images.
