I've been doing a successful lifestyle business for over a decade, the best advice is to research one very specific consumer area, and provide information that will save people time - mostly through presenting research in as concise a way as possible.
Most people underestimate the desire of humans not to think. We all need to do research when we're buying something we're not familiar with, nobody wants to spend time thinking and comparing and figuring out what the best option is - save them time and you'll eventually develop a lifestyle business.
It's important to note that it takes time, perhaps up to 3 years to really get going, but once it gets going, it's like a flywheel that's hard to stop.
What's the last major thing you purchased? Basically, be on the lookout for frustrating purchases, were you not able to find good info? Too many spammy sites? What site do you wish was available to help you with that purchase? If you can't find it, make it.
I can only think of price-comparison or review-based websites. Is that what you're talking about? How could you monetize something like that without ads, for instance?
