I've been experimenting with different ways to spot products earlier and one thing I keep running into is that most of the "spy" or research tools feel outdated by the time I use them. Either the products are already saturated or the ads I see are no longer even running.
For those of you doing on e-commerce, how do you make sure you're looking at what's actually working right now and not what worked last month? Do you rely more on tools, manual digging, or something else?
