My friend Joseph over at Greensparrow Gardens recently posted on Facebook about Google Ads Preferences...basically Google tries to guess your age and gender based on the types of websites that you visit most often. While they at least got my gender correct, Google thinks I'm 10 to 20 years older than I am. I guess I must have very "mature" interests and hobbies! It makes sense though...in a horticulture class I took a few years ago, they taught us that most marketing for gardening products is targeted at 40-year-old women (and you'll see below that most of my internet time is spent looking at gardening stuff).
To try it for yourself, simply click on: www.google.com/ads/preferences
Here's what came up when I clicked on the link:
