SEOCockpit attempts to provide a somewhat comprehensive stats dashboard for SEO's and web publishers. It monitors:
  • Keyword Rankings
  • Backlinks
  • Traffic
  • Pages Indexed
  • PageRank
  • Spider Visits

It has both reporting and alerts. It can create branded PDF reports for SEO's to send to their customers. It's a hosted app, so there's no software to install.

It costs between $10 and $80 a month. That's cheap if you're in this business and these stats are valuable to you.

I have six times as many domains as are supported by their largest plan, so it looks like this isn't the solution for me.
