Hi

On my website i m getting B Grade with 87 points. Now i want to make it  
A and there is a scope to do that.

I have added Google Analytics code which is y my gzip component and  
header expire grade goes to B from A. I need to use Google Analytics so  
cant i set header expires and gzip that?

Another thing is that CDN is not something for a small website. So isnt  
there a way out where we can set CDN as our domain itself. So that we  
get a better grade?

Let me know if there is a way out.

Thanks

For a CDN I recommend Amazon Cloudfront. Super simple to setup and  
use.

OH just noticed. In this forum itself they have added analytics code  
still they r getting A grade.

How they have done it? They are using litespeed server and i m using  
nginx thats the only diff.

no one out there to help me out? Can ne one know how this site i.e  
[ruby-forum.com](http://ruby-forum.com) manages to get Yslow grade A inspite the fact that it  
uses google analytics code in the site?

since when i add the code it reduces the Header Expires and Gzip  
component grade to B from A

thanks
