Here's three helpful tips on maximizing local search from the Duct Tape Marketing Blog:
1) Content - use the names of cities and suburbs on your pages, add your address and Google maps, talk about local and community events in your blog posts and titles. Link out to local sites using town and neighborhood names in the anchor text.
2) Links - this one is not as local focused but get links from your local chamber directories, local school alumni directories, local strategic partners, your blog network
3) HTML - use local words in you title tags of pages, anchor text for internal and external links, H1 tags, bold and italics tags, urls of page names, and alt and title description of images. Make sure anything you do that highlights content makes sense to eyeballs as well. Don’t overuse this mark-up, just use it to help point to your site.
