Will Content Change Impact My Ranking?

I have a blog that rank pretty well for keyword netbook (in my country).
I'm thinking renovating my blog to a ecommerce store.

What I'm worrying is will my content change HEAVILY impact the keyword ranking i'm currently getting? Especially when the structure changed as well.
(From a blog to shoppign cart)

Will I have this problem?

 

definitely....when you are completely changing the content then how can you rank for your prior keyword at the same position?

 

Agreed with shailendra.

Changes in content of the site badly effect ranking of your site.

 

hm...
that is quite a problem.
even for not really competitive domain it will affect a lot as well?
cause i'm thinking of buying 1 website which is rank quite well and reconstruct it.
which means after i reconstruct it i won get the good keyword that previously rank well.
hm...

 

Surely It will affect your PR and SERP for your top keywords worstly.

 

Better keep update the without changing the keyword always good and google like fresh and updated content. Once keep updating will increase crawling rate
