Question

Startups

Suppose "someone" :) has several ideas for creating startups in the web sphere, i.e. these should be online services of various kinds.
These ideas are not unique and at the moment they have competitors that are well developed.
If we analyze these ideas according to wordstat.yandex.ru, then some of them have indicators - more than a million requests per month; others over 30,000 requests per month.
Which of the projects will be the most in demand for users, those who have more requests per month?
Those. if there were few requests per month, then users are not very interested in this topic, and it will be difficult to attract users to the resource, simply because there will be few of them?

Answer 1

How to determine the relevance (or profitability) of the project?

find clients and get money from them

Answer 2

In parallel with the market analysis, we make a landing page that will give an idea of ​​the audience's interest:
1. When creating a page, we follow these criteria.
2. Above the footer (at the bottom of the page) we place the inscription: "Coming soon ..." and the inscription: "Notify me about the opening of the service by e-mail." and the "To:" field.

Answer 3

Run the prototype.

Answer 4

Which of the projects will be the most in demand for users, those who have more requests per month?

Certainly. The more requests, the more demand.
Right. Create demand = create a new market, which is much more difficult, longer and more expensive than satisfying existing needs.
A small remark: put the region correctly when checking the demand through wordstat.
For example, residents of the southern regions are much more likely to look for air conditioners than residents of the northern regions, "expensive" services will be sold only (conditionally) in Moscow and St. Petersburg, etc.
And be sure to look at the history of requests to see the trend: it is better to launch in a growing market than in a stagnant one.

Answer 5

You made a correct mistake in terms. Demand and profitability are completely different concepts. Demand indicates demand, and profitability is a derivative of supply, in other words, the level of profitability. These two concepts can be completely different directions.
High demand (in the context of requests) - Not equal - High profitability (in the context of project goals)
Requests may be few, but in terms of money, the profit from the project will be higher than in a project that has a lot of requests. There are many reasons for this, from product characteristics to marketing policies. A vivid example from the financial market: MFIs buy thousands of leads, and business profitability is often negative. See how many requests for the word loan, etc. The business is in demand, but not profitable.
In a general context, it is difficult to answer your question. Need more specifics.
