... I'd get really, really suspicious if I get targeted that well. As in, they've spent so much on advertising their offering cannot possibly be the best. Yes, I'm a habitual cheapskate. Before I commit I need to know what alternatives there are, what the price ranges are, and so on, and so forth. For some things I'll look up the manual first and look it through, then save it for future reference. See how good or more likely just how bad it is. Look at other devices by the same company. Do they provide at least (hardware maintenance-) manuals for older gear, or do "old" things completely vanish from their site the moment the new batch comes by?
Reviews I'm very critical about because I assume most will be astroturfed in some way. I'm actually most interested in negative reviews and scour them for what went wrong, whether that's likely to impact my intended usage, and how the manufacturer or the vendor dealt with it. Unresponsiveness or stonewalling is enough to stay well away from the vendor.
Pricing I take from price aggregators, and from there figure out an acceptable price range and where to get it in my neighbourhood. Then I go there and pay cash. Want my custom? Make sure I can find you, and that your prices are in the right bracket. If I'm interested, I *will* find you, but if you tried too hard to find me, I'll stay away for that reason.
Now, I'm probably an outlier. But I think "the web" has enabled a rather larger shift, away from having the product find the customer and more toward the customer finding suitable products for his needs. If that catches on, and it might well with the younger generations, then advert targetting profiling becomes far less important.
Instead, focus on listening to your customers and possibly would-be-if-only customers, and see if you can't come up with something good & useful for them. The marketing can then look much more like throwing it out there and watch it take care of itself.
