I find it unlikely Google presents drastically different results (or adverts) for someone who is interested in DIY versus someone who might be looking for a contractor. Mostly because it's a terrible thing for Google to try and guess. While Ted might find it convenient to target people based on whether they are wealthy homeowners who hire contractors or DIY guys, I have no interest in sharing that information with Google (or Facebook). It's neat for Ted, not so neat for me. Other things which might result in "better" advertising which I don't like: - Companies scanning my license plate while I'm at Home Depot. - Someone camping the county building permits office with a video camera and facial recognition software. - The phone company forwarding my phone records to advertisers. All of these are similarly invasive to Google & Facebook's tracking and equally disgusting. This is all particularly true since just buying the Adword for "Drywall Repair" in my area, would likely yield the exact same results without tracking.
