I work for an e-commerce site that has lately been shedding its workforce. I was hired ten months ago as a UI Developer. At that time we had three other developers. One was the technical lead who had been with the company for 10 years. The other two were server-side developers who had been there for 10 and 3.5 years respectively.

In ten months, the technical lead left for a better position, one developer was laid off, and the other very recently left. So, I am now the only developer on staff. We have one DBA and one network administrator.

They are currently looking to hire another developer but are not willing to pay enough to hire a senior person. I consider myself a junior developer with two years of experience. I have argued that we need to hire at least one senior developer and another junior developer if we're going to keep our current site operational (not to mention develop new features)...even if that means laying off staff in other departments.

Right now we get 6.5 million pageviews per month, and I feel like 3.2 million pageviews per developer must be incredibly abnormal.

My question is then: what is a normal developer to pageview ratio? Are there any industry standards or literature on the subject that I can use to argue for more staff?
