Considering redirecting my site from .com/us to just .com. What could the possible SERP consequences?

Today we use country-specific .tlds but have the US site on .com/us; .com is now a 'flag-site.' Ikea uses that structure too (.com/.com/us). Looking potential risk to redirecting current US site to .com.

The biggest concern would be potentially losing some of the PageRank passed. However, in my experience, these kinds of internal redirects tend to go off without a hitch if well executed.

1. Make sure that you have a good understanding of all URLs that are to be redirected and that the redirect does occur correctly.

2. Watch analytics, GWT, and server logs like a hawk the first 48 hours after the redirect to make sure you aren't missing.

3. Consider doing Sitemap Assisted Redirects (Google it) to speed up the process
