Offline business website SEO strategy - what would you do?

Hi Everyone,

I am doing some website work for an offline service company in Australia. My normal plan of action for all offline sites is wordpress site with Aweber + lead-capture + good copywriting + SEO = qualified traffic. This works well of course. In this case however, I don't have the luxury of starting from scratch, so I'd like some advice.

The company owns these three sites (none of them built by me... this is what I'm here to fix)

* www.companyname.com.au - PR3 - the site has been given a makeover in the last week. Whilst it looks great, much of the content has been changed/dropped, so I'm not sure if Google will notice the changes and demote the site's ranking? The SEO is also not good (every page has same title & keyword for meta). It also has some broken links & is not quite finished (maybe 98% done).

* www.major-keyword.com.au - PR1 - this site has been growing slowly, with content added gradually. This site doesn't look as good as the new site (might not convert as well). This is a Joomla site.

* www.major-keyword2.com.au - just a domain, no site yet.

I wonder what is the best approach to take:

1. Should we drop the two keyword sites and focus all efforts on the companyname.com.au
2. Should we create a spoke-and-hub type setup with main site & interlinking.

NOTE: Google Places/Maps is an important source of traffic... but it is currently setup to point to www.companyname.com.au. It has an old street address that needs changing. I feel like we might get penalized for changing the address when the old address is floating around on some other online directories. (advice/tips please?)

I would greatly appreciate warriors input on this. My main concern is to get this web project making money for the business owner who is trying his best to make his Internet strategy work!

Thanks all.
Shona
