Does a similar CMS fabric/theme used by 2 colleagues, cause SEO issues?

[toti588]

Does using the same CMS fabric/theme with substantially different content for each website but the same business address (on google places and the websites) cause SEO issues?  For example: 2 colleagues with somewhat similar services located at the same business addresses desire to use the same CMS fabric /theme  but will have different content on the sites.  Will this hurt their SEO / should they use a different website skin/theme?

toti,

I assume it's not the theme that's the problem in google my business (google places) rather, it's likely their shared address. If two businesses are using the exact same address (and phone number too?)  google may have problems with it.

As  far as two website having the same theme but different content--that is not a problem.
