Can you please tell me how to increase our eCommerce pharmacy website traffic and page rank in 2014 .
Thanks in Advance.
Pretty much the same way you increase traffic for any other site. 
Sorry, but your question really is much too broad to attract any meaningful answers.
We have a number of threads on the subject, so I suggest you have a look around the forum and read some of them. You’ll also find useful advice in the sticky threads at the top of this forum. If you’re new to SEO, then you should also read Google’s “Search Engine Optimization Starter Guide”, which you can download from the link on this page: https://support.google.com/webmasters/answer/35291?hl=en&ctx=cb&src=cb&cbid=1h0dcl2owc3c2&cbrank=0
After that, if you have a specific question which has not been answered, please feel free to post again. Meanwhile, I’m closing this thread.
