Not quite convincing, right?

I’m not an expert like Neil Patel. However, by tried and true practices, I managed to improve my website page speed insight from 70 to 90+ (Some pages 97+) score.

Let me walk you through the steps I did to achieve that result. Surprisingly, I didn’t buy expensive plugins to get here. I only spent money on one thing, which is:

Step 1: Get a decent hosting provider

I cannot stress this enough. A low quality host can do a lot of damage to your site. Even if you have a perfectly optimized site but if your hosting sucks, your page speed insight score will not be improved.

As a software developer, I prefer VPS hosting since it gives me a lot of room to customize. The site you are on now is running on a Digital Ocean droplet with 4GB of RAM, 80GB SSD and 2 vCPU. It currently handle ~ 10k traffic monthly quite nicely.

I think with these specs, my site can handle up to 30k visits/month.

If you plan to have a lot more traffic, you will need to upgrade your server accordingly.

If you are starting out, a droplet that cost $5/month should be enough. You can upgrade as your site grow.

Remember, get decent hosting provider. From my experience, I would recommend DigitalOcean for developers and Flywheel for people who need an easier interface.

Step 2: Get rid of bloat plugins, themes

Plugins and themes are the main reason why so many people use WordPress. If you need to do anything, there is a plugin for that. If you need to change your site looks and feels, there is a theme for that. However, this flexibility comes with a cost: speed.

Beside adding more static assets (js, css, images), plugins and poorly coded themes can slow your server down by abusing hooks. If you place a timer inside do_action and apply_filters in wp-includes/plugins.php, you can find a lot of plugins’ code that cost your server extra time to prepare for the content.

Here is the result I got from inspecting these functions on my site:

Placing log to find out which filter cost time in WordPress

As you can see, the highest cost from the image above is 47 seconds. Each time a plugin calls add_filter or add_action, there will be time added to the total load time of your site.

So, consider using less plugins. Only keep the ones you can’t live without.

As of themes, I know that many people don’t have the luxury that I have. I built my own theme so I can get rid a lot not needed code. If you can, build one or high some good developer to build a custom theme for you.

The different will be night and day, I’m sure.

Currently, I have only 17 active plugins on mys site.
