WP-Optimize preload key request feature details

The latest updates for WP-Optimize 3.1.7 have now been released – including the preload key request feature. We have taken a lot of time and effort to launch these new improvements and hope that they further help improve users’ experience of WP-Optimize. 

When aiming to improve the speed of your WordPress site using WP-Optimize, one of the new features we have released with this update is the ability to preload key requests. Preload key works by using an audit to identify which resources to preload on your WordPress site. The browser will then preload resources so they are available immediately when needed, preventing eventual waiting time later on, making your site load faster. Google’s pagespeed insights will often suggest preloading the requests to font files and other assets as a speed improvement:

With the latest WP-Optimize Premium release, you now have the ability to manually add any resource you want to be preloaded:

As can be seen in the Google PageSpeed insight test, preloading key requests can result in massive time savings when visitors are loading your site.


In order to get the URL to add to WP-Optimize, just right click on the resource and copy the URL:

Next, past the URL in the ‘New Asset’ box of the ‘Preload key requests / assets’ section of WP-Optimize and press ‘Add’. 

The URL you added you will be added to your preload key requests.

The updates to WP-Optimize 3.1.7 also includes the following:

WP-Optimize release latest 3.2.3 update

The latest update for WP-Optimize 3.2.3 has now been released. This new release features a fix, feature and a tweak update. 

The main focus in this latest release is the ‘Preload Minify Assets’ feature. While WP-Optimize does already have a ‘Preload’ feature with caching functionality that can preload all pages and minified assets, this new update now gives users a separate minify preload feature for users who are using a hosting provider that provides server level cache – such as Kinsta. 

As such, if a user is using a hosting provider that uses ‘Nginx’, rather than ‘Apache’ – these hosts most likely provide caching themselves. In this scenario, users of WP-Optimize need to disable the caching functionality within the host, as they are unable to use the ‘Preload’ function. Even on ‘Nginx’ servers, minified assets are allowed and preferred in order to boost performance. 

The updates to WP-Optimize 3.2.3 are available for download now and also includes the following:

  • FIX: Cache – ‘Purge cache permissions’ setting does not allow additional roles to access the purge cache tool
  • FEATURE: Minify: Pre generate assets
  • TWEAK: Make smush details button work in media modal window

Preload critical assets

Preloading of critical assets is a premium feature of WP-Optimize.

Some assets which are considered critical might be loaded later because they are included via a script or from within a CSS file.

A typical example are font files, background images, or scripts which are loaded from an other scripts. They will typically start loading once the other assets have been downloaded and parsed.

Preloading those assets will enable them to be loaded in priority, and could result in a faster page load.

WP-Optimize expands to a market leading 3-in-1 optimization plugin with new caching feature

After a lot of development and hard work that has included our recent image optimization feature, we are excited to share with WP-Optimize users the latest breaking news; The all new caching feature has now been released! This new development makes WP-Optimize a market leading 3-in-1 plugin that now combines caching, database cleaning and image optimization that now all work together to help make your site run faster. WP-Optimize caching has been a highly requested feature that we have now available to both our free and premium users.. 

How does caching work?

Caching makes the most of your WordPress posts and pages by loading them as static files. When these static files are viewed by users, it reduces the amount of processing load on the web server and overload if PHP and MySQL are used. This can help improve the performance of the site and is a sure-fire way to ensure that web pages load at lightning-fast speeds.

How to use the WP-Optimize caching feature

Video walk-thru: While written instructions on how caching work can be helpful, for many users a simple walk-thru video can be a lot easier and quicker to process and understand. So be sure to check out the following video we made that takes you through the process of how to use cache. 

Setting up caching:

With WP-Optimize caching, we have specially designed the feature to give a wide range of options to the user. However, if you are the kind of person just wants to turn something on and let it run, just toggle the “enable page caching” button and we will automatically optimize all the different caching tasks for you. This feature enables users with all levels of knowledge to access the full advantages of caching.

How the caching settings appear in the plugin

If you prefer to do things yourself and dig into the finer details, you can manually setup your sites caching options yourself.

Mobile and logged in users cache

If you prefer to setup the cache yourself, there are options within the plugin that will let you manually set “mobile” and “logged in users” cache. Mobile cache enables users who access your site via a mobile or tablet to get a device specific cached version, while “logged in users cache” enables secured cached content for all of your logged in users. If you want to enable this option, just toggle the buttons to the on position. The options are just the first in an amazing long list of features that will make your site faster.   

Enable Mobile and logged in users cache

Preload options

You can further optimize your caching with scheduled preloader options. This features works by allowing the user to preload the pages of the site, further improving its performance. When combined with the other caching features within WP-Optimize, the preloader is a powerful tool that can help speed up loading times.   

Advanced settings

In the “Advanced settings” tab, you can add any URLs, cookies and user agent strings you would like excluded from the cache. These options can be a great tool and very useful as they allow you to exclude sensitive site pages from the caching engine, such as login URLs.

G-Zip compression

This option can give a huge percentage boost as part of your total savings and is a simple and effective way to save bandwidth and further speed up your site. G-Zip compression reduces the size of files sent from your server to increase the speed to which they are transferred to the users browser. Just click “enable” to activate this option.  

Static file caching

Finally, “Static file caching” lets you use HTTP response headers. Once enabled, a visitor’s browser will know if it should cache non-changing files, so it does not need to retrieve them upon every visit, further improving the loading speed of your site. Just set your expiration time and press “enable” to activate.

WP-Optimize in summary

The caching feature is the latest in a series of site optimization options that aim to make WP-Optimize your one stop shop for improving your sites speed and performance. Along with image optimization and database cleaning, the addition of caching aims to make WP-Optimize the only WordPress optimization tool you need.
