This one is a biggie for me as well; SEO issues are a big one with our site, so having some kind of plan for handling this is majorly important for some sites.

I definitely added my 3 votes for this one; something that allows you to also monitor the bandwidth you're consuming - with our particular site, if there's a certain type of news incident, traffic spikes tremendously, and having some kind of bandwidth indicator to be able to judge the spike and increase capacity to handle the load would be very useful. Even just an overall usage dashboard (requests, CPU load and memory, as described above) would be helpful.
