There are some web hosting providers like WP Engine, Godaddy, etc. that have blocked cache plugins as they have built-in the caching system.
You can still use the Autoptimize plugin to optimize your WordPress website speed. The best part of this plugin is that you can use Autoptimize plugin with other cache plugins like WP Fastest Cache, W3 Total Cache, WP Super Cache, or even Swift.
I am using the Autoptimize plugin with WP Fastest Cache (free version) to improve my WordPress site speed.
In this post, I have shared the best Autoptimize plugin settings 2021 to Speed your WordPress website. You can also check out my complete post on How to Speed Up WordPress Website With 100% Gtmetrix Score.

How To Properly Configure Autoptimize Plugin 2021
Under JS, CSS & HTML Tab
Add try-catch wrapping – disable this. Enable this option if you have any JS errors.
Optimize CSS Code – Enable this.
Aggregate CSS – files – Enable this as it will combine all the CSS files into a single file.
Generate data: URLs for images – Enable this if you are not using any CDN. It includes small background images in the CSS file instead of as separate downloads. This will make fewer HTTP requests. But if you are using any CDN then disable it is an option.
Inline and Defer CSS – Enable this. Run a speed test in Gtmetrix. If any CSS file is still showing, then you can line and defer the CSS file. The best tool to inline and defer CSS is criticalpathcssgenerator.
First, enter your website URL.
Next copy the entire codes from the CSS file and paste that code in the full CSS box.
Now, click on the create critical path CSS button to generate the file.
Next, copy the newly CSS file codes and paste that in the inline and defer CSS box.
If you have more than one CSS file then you can generate separate codes, just give some space in the inline and defer CSS box and paste those codes.
Inline All CSS – Disable this. You can either choose line and defer CSS or line all CSS. Autoptimize does not recommend enabling inline CSS files.
Exclude CSS From Autoptimize: same as the exclude JS files, you can exclude certain CSS files. If you are getting any error from any CSS setting then you can paste the path to exclude them.
Optimize HTML Code – Enable this. This will reduce the page size by removing whitespace.
Keep HTML Comments – Enable, if you want to optimize your blog comments otherwise Disable this.
Cloudflare does not provide CDN URLs, instead you have to change your Nameservers. So, if you want to set up Cloudflare CDN then you can check out our blog on how to set up Cloudflare CDN.
Experimental: Enable 404 Fallbacks: Disable this.
Also Optimize For Logged In Editors/ Administrators : This option is up to you. You can either enable or disable this for your editors/administrators.
Autoptimize plugins also come with built-in ShortPixel for image optimization. You can even optimize your image to load on WebP format in supported browsers.
Optimize Images: This will load your images from Shortpixel’s CDN & your images will load faster.
Image Optimization Quality: You can choose any of the three image optimization quality options. But you might be thinking about which one is the best choice for your website. So here is the difference between all the three types of image compression.
Among all these three options, I use Glossy for my site.
Load WebP in supported browsers: Enable this option, as it will load the WebP version of your images on the supported browsers.
Lazy load images: It means that the images will load as the visitor scroll down the page which makes your website load faster. So, I will recommend enabling this option.
Critical CSS is a paid feature and you have to install Autoptimize criticalcss.com power-up plugin. The plans start at $7/month.
Google Fonts: If you are using Google Fonts in your site then you can either choose Combine and link in head (fonts load fast but are render-blocking) or Combine and load fonts asynchronously with webfont.js. Test both of these settings one by one and see which one works best for your website.
Remove Emojis – Enable this option. removing emojis will reduce your page size.
Remove Query Strings From Static Resources : Enable this. This will remove your score in Google page speed, gtmetrix, Pingdom, and other website speed test sites.
Preconnect To 3rd Party Domains: Here you have to enter the URL of the content/script page like Google analytics, Google fonts, etc. This will begin the process of connecting 3rd party domains before the request is made on the browser and thus improves your Website speed.
Preload Specific Requests : This will tell the browser to download an asset as soon as possible. This will speed up loading time of those assets like fonts, scripts, etc.
Optimize Youtube Videos: If you have youtube videos on your site, then you can use WP Youtube Lyte plugin which is also developed by Autoptimize developers. This will lazy load Youtube videos just like the images and will load when a visitor scroll down & clicks the play button.
