Oh heck...Do you realise the complexity of what you are asking?
If I were to answer this in full it would take so much time that I have learned over the past xx years it would cost a small fortune!
but what I want to achieve is better rankings in local markets.
In my experience, YMMV, forget WMT tools, the only sure way I have found is to have a site under a ccTLD with LOCAL contacts etc or a regional TLD such as .asia
One thing I will give you for free is these other ccTLD/TLDs can take a long time to rank in US Google.com BUT can easily be #1 in their own Google.ccTLD...right, you probably now understand I am writing about geo-targetting on a local/national level.
The one good thing about all this is that Google does not seem to mind if one has all these different sites on the same sever IP serving these different countries, mine are all UK hosted without, seemingly, any problem.
I have one CAVEAT with my advice.
I have been doing this since BEFORE Google even started and DURING all their algo/geo advances/changes...I have no idea how much my sites are considered by them as good/bad/acceptable and also bear in mind that when I launch a site it very rarely gets changed/updated very often since the information is evergreen.
