What are the SEO KPI's (key performance indicators) you track? What is a reasonable goal for a month? There's really no right answer here because it depends on the client's objectives, and the guy's role. What I'm hoping for is that they say something intelligent about different KPI's like counting and tracking links, social shares, unbranded organic traffic, referred visitors, engagement metrics, conversions, etc. (Hint: "mad hits" and "keyword rankings" are not metrics I care about.) Even better if they have tried out different metrics and changed them over time, and can explain why.
