Greeting friends,
we all wish to have a blazing fast website or a blog that everyone wants to visit. But optimizing the performance of a website is not easy and it is not that tough too. Most of us use various caching and javascript/CSS minify plugins to boost performance. But these plugins come with their own bottlenecks and they too consume the website resources. So these plugins don't always help especially when you didn't have a dedicated website hosting server as most of us use the shared hosting service for our blog.
So I researched a bit looking out for plugin-free ways to improve the speed of my blog. And I brought all these methods together and published through the below blog post. So any friend wishes to experiment with these tips, he is welcome to read them from the below post.
For your information, I was myself used these tips on my blog and its performance improved from 65 to 76 for mobile and 75 to 91 for my blog (https://www.techbeamers.com/). You can check it from the google page speed tool.

Thanks all.
