I know that my site's SERPs are important to the success of their marketing. (And I can hear Skinner saying, "Duh Martin!" ), and so I run daily checks on them to see how they are performing for their specific keywords. And since this is a daily task for me (ok I admit...hourly ), I was wondering if you all also check your anyalitics daily (or hourly)? How many times do you use either web based tools, or installed software on your PC/MAC/*nix to check your SERPs (and PR if you care for it)? What do you use to check for them?
