Hey there!
I wont bother you with a generic proposal or introduction
Here's my plan to improve your sites speed
1. First of all you need a CDN (Content Delivery Network) that reduces the physical distance by redirecting users to the nearest CDN which improves your site speed globally. Other than that it also improves page speed, handles sudden traffic, block bad bots, reduce bandwidth consumption & protects site from DDOS attacks.
2. I'll compress all the images on your site without losing any quality to improve speed
3. I'll reduce your first byte time which has a huge impact on speed
4. Cache setup
5. Remove render-blocking JavaScript
6. Enabling browser caching and Gzip
7. Improve server response time
8. Minify CSS, JavaScript,HTML
9. Eliminate render blocking CSS & JS
So these are the steps that i'm gonna follow & hopefully give u 100 page speed or almost 100 page speed
If you like my plan then message me so we can discuss this further
or just send me your website url so i can run some tests & tell you what needs to be improved & how i can do that
Thankyou,
Hamza Khan
