A lot of redirects – how to minimize them?

Hi.

My site has became very slow, and I just tested it on http://tools.pingdom.com/fpt/#!/eqEWzL/http://bloggerspoint.dk and it seems like there is a lot of redirects, that I have no idea of where is coming from.

There are redirects from Google, pixel, double-click, and a lot of sites I don’t know. Is there any possibility i can find out where these redirects are coming from, and then remove them?
