How to Optimize Comments in WordPress?

Did you know comments are also using resources to load?

If you are using Gtmetrix to check your page speed then check the waterfall section.

There you will find all the requests with load times including comments.

Comments are taking time to load and impact the overall performance of your website page performance.

And as we all know the new algorithm where Google officially confirms that website loading speed is one of the main ranking factors.

Bloggers take this seriously and start improving their core web vitals.

I already achieved a 99+ performance score and told about that in most of my articles.

But in short, to achieve a loading speed under 1 sec you have to,

  1. Change your server from shared host to Cloud host.
  2. Change your theme from bloated one to speedy one.
  3. Start caching HTML, CSS and Java files.
  4. Optimize database.
  5. Connect Cloudflare CDN.
