Blogger Layout Changes Affecting PR and Traffic?

I just recently changed my layout for blogger and now when I look at my traffic stats I notice a big change. No visitors from search engines, only from forums, etc.

So my questions are:

Was changing my layout the reason for this?

Does it affect PR as well?

 

yes, not just search engines but also forums, blog you can get rank

 

wrong answer...

 

You didn't provided your blog URL..

 

Check if any nofollow or noindex tags added into your layout !!

 

I don't think so that changing layout affect traffic. There are some other factors that affect traffic of your blogs or sites.

 

Of course changing layout will affect.
