I am also a owner of website related to Medical and health related Job professions. SEO, social media traffic and organic traffic are the important terms besides of pagerank and alexa rank. Pagerank is just a numeric value assigned by Google after valuating all reference links (backlinks) to your website. Similary, Alexa rank is also a numeric value assigned by Alexa.com ( An amazon.com proprietary) after predicting the traffic of a website.
For better SEO and more social media traffic, I always use my 3 step strategy besides of my regular SEO efforts. After latest Google SEO Update (Penguin update), this is the only working strategy for SEO.
1. Quality Content – The only thing that brings traffic and recursive visitors to your website is your informative content. Better is your content, more people will give your reference to your website and this will result into more links ( means good SEO) as well as better Pagerank.

3. Strong Social Signals – Google has mentioned social signals as an important ranking factor in search engine result pages. So, be active at Social media like (Facebook, Twitter, Google +, Digg, Reddit etc.
These three are the best SEO techniques in present scenario. Follow these, you will observe an incredible growth in your traffic and website reputation.
Overall, I can say to you is “*Always Focus to make a brand. No website can survive for forever, until its a brand name.*” Above “3 step strategy” will turn your website into a brand.
