How to find and choose an idea (niche) to start a business?

Question

Social media

In general, it became interesting what resources can be analyzed and used to find an idea and choose a niche using only social networks. What useful information can be collected and the result obtained. For example, hashtags, the amount of activity, etc.
I wonder what kind of business AI would start, what would be the disposal of the Internet.

Answer 2

for these two months. if I had followed the events in politics and IT, I would have done a bit on the buck ...
damn it, does this mean you are talking about August 2 ?? tsezh was the most delicious day, or rather the end of July, when I was overstocked at 62 kopecks)))
here’s the deal for you:
bought on August 2 at 63 = 4760ye
sold on September 7-11 (when the peak was passed and rolled down) at 70 = 333200
for two 33,200 months for a few movements of the mouse... and a bunch of gray hair)))
well, minus the cost of a broker, bullshit)))
right now, at 65 again, you can go to bucks, it seems to have gone up. look at it and politics, the situation is getting hotter))) we'll see what happens in a month)))
and who is more dexterous, then worked 4 peaks in 2 months!
Aug 1 63.00 buy 4760ye

23AVG 68.20 We sell ue, in your pocket 331500
24AVG 67.10 we buy 4940U
30AVG 68.20 We sell UE, in the pocket 337000
31AT 67.50 1,590UE 10CAMENT
UP, in the
CE we fix: for 2 months the gain = 51800 . or we swing further)))
to buy and sell naturally on the stock exchange, and not in exchangers around the corner)))
although it jumped in such a way that people also made money through exchangers ...
I did not have time to distribute, I spent them in the country of origin)))
but three orders of magnitude more fuss with your garages ... and also tax and so on)))

Answer 3

If we take the classics, then this is wordstat. Allows you to find out what people are interested in in a particular region.
But it’s not enough to analyze only needs, you need to look at who else and how satisfies these needs.

launch a landing page for a business idea, look at Crowd funding, etc.
