Why wont my website rank well?

[Rohan]

The key to showing up on Google is to use good metadata. Use aboutus.org to make sure your site shows up well in searches, and use their tips to optimize your website.
Make sure that you register your site with Google Webmaster Tools. Until you do this, it will not be indexed. Yahoo, Ask and Bing have similar services.
Check that your site has a robots.txt file, and if it does, make sure that it isn't blocking pages from being indexed by search engines. Set up a sitemap on Webmaster Tools to help more pages be indexed.
Finally, ensure that lots of other pages link to your page. Try posting your business to contractor forums, or the Australian equivalent of Angie's List or something. Make sure you have a Yelp page (or, again, the Australian equivalent). The more linkbacks there are, the more likely it is that your site will be indexed by search engines.
