Yes, I can definitely help you with your website speed.
I have increased speed up Hundreds of WordPress websites for my clients and made them get 90+ scores on PageSpeed insights.
Let me ask you a question, is your website WordPress?
If yes then you should check out this tutorial on increasing WordPress website speed.
And if not, then there are 3 things which you need to focus on mostly:
1. Image Optimziation
- Make sure each image is not greater than 60kb.
- Try Lazy Loading the images and iframes.
- Instead of resizing a 2000px wide image with CSS or HTML, first resizing the actual image with any image editor, and then upload it.
2. Enable GZip Compression
- This can be done using .htaccess code, which you can find on the above tutorial link I provided above, that works for all kind of websites.
3. Content Delivery Network (CDN)
- Use Cloudflare's FREE plan for this.
- No matter from which country your user is opening your website, CDN will look for the nearest region and serve all the static files of your website from the closest region.
- Also after installing CDN, changing nameservers, make sure you add PAGE RULES which you can find on the above tutorial.
- It will fix your TIME TO FIRST BYTE issue.
Follow the above three steps and this will help you get 80+ scores easily on pagespeed insights and gtmetrix.
