I currently have a website doing really well in search engines with a google rank of 3 and generally gets good hits.

My concern is that its dated and I am going to totally change the site with new ecommerce software, which I am worried will destroy my rating or have to start again in google.

How can I prevent this the best way?

Thanks

what kind of change are you talking about?

same content, i.e same products but totally new software, so all pages will be reindexed, new site map the lot...

What do you think?
