How to turn off advertising in Gmail

I can’t believe I didn’t know about this until today. There are two places that advertising appears in Gmail. They can be in the side bar or at the the above the Inbox (they call these web clips).

1. To turn off ads in the sidebar, go into Mail settings -> General -> Importance signals for ads. Click on the link and opt out of advertising in Gmail and when you go to search too!
2. To turn off web clips above the Inbox, go into Mail settings -> Web Clips. Uncheck the box next to “Show my web clips above the Inbox”

There. Isn’t that better?
