Best WP Fastest Cache config to boost your WordPress site speed.

81 / 100

WordPress as a content management system (CNS) is amazing. All you need is an idea and you can make a website within a single day! Yes, it is that easy to use, but it is a bit difficult to make a website that can compete for top positions in any search engine ranking.

That being said, it is of course achievable and the first step is to optimize your website. This will not only improve your SERPs but also improve your user experience.

The world is now coming to 5G technology and nobody wants to wait more than 5 seconds for a website to load. In fact, according to Niel Patel, ”40% of people abandon a website that takes more than 3 seconds to load.”

So with that in mind let’s start with how can we improve our site speed and without a doubt WP fastest cache is one of the best plugin available for this. I want to keep this article generic so I’ll be using the free version.

This means that certain functionalities can change the way your website is built currently. So before making any change it is wise to take a backup.

My Configuration of WP fastest cache settings

This configuration has helped me double my page speed score and also helped me achieve a 92 GTMetrix score! My website was loading at more than 10 seconds and now it was under 5 seconds. Of course, there are other factors like theme and hosting but WP Fastest Cache had a major part to play!

2. Delete Cache Configuration

Once you are done with basic settings, you will have to set a rule for deleting the cache. It is advised to clean your cache timely. This helps in keeping the cache file updated. You should time this at a time when you do not see much traffic on your website.

All you have to do is click on the Add New Rule button. Then select “All” in the first drop-box. I recommend clearing the cache once a day. Then again it depends on your website. But try not to go beyond 3 days.

3. Image Optimization

This is a premium feature that will help you with optimizing your website using one of the two compression techniques. One is Lossless and one is Lossy.

Lossless compression will decrease the size of your image without losing important pixels in your image and Lossy compression on the other hand will reduce the file size significantly but may decrease the quality of the image too.

There are many free plugins available for this application that can be paired with WP Fastest Cache free version. One of them is Smush.

4. Exclude Settings

Now, this is what a life-saving jacket is like. With this section of the plugin, you can exclude the particular file that you don’t want to cache.

Sometimes while caching your theme may face issues regarding showing some images or effects like parallax. You can find those particular files and add them as a rule to exclude. This will tell the WP Fastest Cache plugin to not cache those files.

Check out our guide on how to implement a parallax effect on your WordPress blog.

Not only that you can even exclude user agents of social media like a Facebook bot or Twitter bots. This helps the bots see and present the current version of the website.

5. CDN Setting

CDNs can improve your site speed by hosting static content of your website at multiple servers and when a request is made by a browser, it will automatically send static content from the nearest location to the user location. Thus decreasing the TTFB of your website.

Check out our blog on CDNs to know more.

If you have a good hosting service then you just have to configure them to the plugin with the host. Else, you can go with the basic plan of Cloudflare. It is good for simple websites and can help you with page speed score. But if you have a big website then you can consider purchasing a paid plan.

CDN by the Photon is also free and easy to configure. All you have to do is select one of the give CDN URL and select the type of files you want to host with the CDN. You can even add specific keywords to store or exclude files apart from the given options.
