How to boost server response time

My blog is http://www.kuchjano.in, when i checked it with Google page speed insights i found that my website has a server response time of 8 seconds. I tried contacting Godaddy for this but they said that there is nothing wrong with the parent server. Can someone help me with this,

If Godaddy is saying there’s nothing wrong, you may want to run a number of tests over a period of time.

You could have run a test with PageSpeed at a time when that server was highly utilized, especially if it’s shared hosting.

I ran a WPT on it: http://www.webpagetest.org/result/160525_4C_26R4

It looks like you’re running Wordpress, so you may want to look at the plugins you have installed and make sure none of them are causing any performance issues.

Also, I see that you have a lot of redirects to 3rd party sites. The performance of these sites could be affecting what you see in PageSpeed as well.
