I don't know if this is in the right section, but here goes...

For those of you with multiple websites, primarily adsense-based niche sites, how often do you check on your websites when they have good rankings?

Also, what things are you checking for when you check them?

Do you check to make sure backlinks you built are showing up?

Do you check to see if your content is scraped?

Do you check to make sure no one has hacked you and installed malware on your site?

Do you check your rankings?

Do you check out the competition?

What are some good things to check and how often should we check them?
