Doubt regarding Google Page Speed Score?

I was trying to improve the score on google page speed score. Now I have reached 91/100.
But now it showing suggestions as
1. Defer parsing of JavaScript

    410.8KiB of JavaScript is parsed during initial page load. Defer parsing JavaScript to reduce blocking of page rendering.

2.Leverage browser caching

    The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:

Actually what can ido for these things? I don't have a clue. i tried editing the values for expiry in .htaccess file, but nothing seems to be happening for these listed things.

My platform is wordpress and I use w3 total cache plugin!

 

this plugin generate a lot of loads, that is what I guess : - w3 total cache plugin!

 

i didn't get you! :/

 

A 91/100 is damn good!

 

thanks!

 

I think it is virtually impossible to get a 100/100 score unless it is a straight text page with no included files.

I think you are in good shape with a 91/100 score as long as you have seen improvements in the overall speed of your site.

 

oh, ok! Thanks.
I thought of correcting the errors shown in the suggestions.
And when I take the page speed test(not in google speed score) its saying my page is very slow, it takes 5.6 secs to load! Thats why i thought of tweeking it more!

 

wp cache plugin is useless, i believe this.

Regards

 

i don't think its useless. Anyway now that you have said, I am disabling it and give it a try!

 

91/100 is good enough. congrats!!

 

One thing you can try to do to help defer javascript is to implement an asynchronous version of any javascript you include. In order to do this, you usually need to modify the code slightly. You will have to check with each third party javascript to see if they offer an asynchronous version, and if they do then they will provide the code to do this.

Asynchronous code allows a page to continue loading without waiting for the code to finish. So typically if you are loading a third party javascript you will have to wait until it loads entirely for a page to be listed as completely loaded, but with asynchronous code, once the initial request is sent to load the code the rest of the page continues loading and does not wait for it. This can help to speed up your page load time.

If you are using Wordpress, also take a look at the number of plugins you are using. Do you really need the plugins on all of your pages? Plugins can definitely slow down the page speed in Wordpress.
