No, hosting locations are irrelevant to search engines, google's webmaster helpscreens (link broken on purpose, yoursite.com is a hosting company, oops, and you have to be logged in to your google dashboard)
https: //www.google.com /webmasters/tools/
pageanalysis?siteUrl=http%3A%2F%2Fwww.
yoursite.com .com%2F&hl=en
make no reference to server location, or domain, the site is indexed on the relevance of its internal text, to the keywords in meta tags, by the number of external links to the site, its relevance to other webmasters. large numbers of Aus only sites have .com domains
The fastest way to get higher up google searches is to keep the First page of your site relevant, not a flash welcome banner that has to be 'click to enter'ed and to do a link exchange with other sites. If you want regional information put it in your home page
Code:
</head><body>
This paragraph is for search
engine readable text, doesnt need to be 50k
to get across
This paragraph is for
screen only items, menu, navigation, clock
This paragraph is for print text,
people that print your page, dont need nav,
your info at the top of the page
the code above as a php,ssi,asp include puts search engine friendly text at the top of every page on the site only writing it once
