Hi David,
Exact Match Domain (EMD) names are currently being ignored by Google. A while back Matt Cutts (the leader of the spam team at Google) said it should have the weight people give it. Watch this video for more information.
In September 2012 EMD update first came into effect to prevent poor quality sites from ranking well simply because they had words that match search terms in their domain names. When a fresh EMD Update happens, sites that have improved their content may regain good rankings. New sites with poor content — or those previously missed by EMD — may get caught. In addition, “false positives” may get released. Our latest news about the EMD Update is below.
As Thmoas and Daniel said, focus on the quality of your content, usability (which is the biggest next thing in SEO) and accessibility. Ensure that your website is all about your customers and the product, NOT about search engines.
Ensure you help search engines and users find the useful content on your website, relate to relevant pages using internal linking, breadcrumb and relevant keyword optimisation between linked pages. Ensure you dont have orphan pages and watch your Analytics system to know which pages are being viewed most, have most time on site, referred, these are the pages users love. If you see high bounce rate and exit rate, or drop outs from some pages, these pages need some serious improvements.
And never buy traffic or pay to include your links in linking schemes, focus more on PR for external links and probably editorials. Partner with blogs and webmasters to host articles with relevant and high quality content on their blogs.
I hope this can help.
Regards,
Issa
