That's what stops me from buying a fixed ebook reference on niche selection.
When you buy a brand new car and drive it off the dealer's lot, you just lost about two grand of the money you spent right then.
When you buy a new pc, a few weeks later something new gets released, and what happens to the money you already spent on the product that you just bought?
It descends in value, doesn't it, now?
It does. Happens all the time.
How soon before these top 96 niches at the top of the publishing heap get superseded by a currently lower placed niche in publishing.
All you need to do to confirm my point is to go to Google Trends. On the morning of one day, something's trending big time. On the afternoon of that very same day, something new bumps it to the shoulder off course from where it was that very morning.
If I'm going to invest in niche research, I'm going to need a device that can yield me niche results with far greater staying power than a book recommending the top 96 niches up there right now.
Any suggestions for such a reliable niche gauge?
