Add rich snippets to magneto website

I would like to add rich snippets to my website and get more traffic. I'm unsure how to get this done myself and am opening the project up to freelancers, who can advise me on how to implement this and who will carry out the work. The website is built in Magento 1.7 I want somebody who can look at my site and give me good advise not only on this but other matters of SEO relevance. Thanks
