A million dollar idea?

Question

Startups

Okay, I have a million dollar idea. Let's say I implemented it. However, even after the release, the application remains on the sidelines. Yes, I can lay out 10-20 thousand at the first stage, at least for advertising. But it is unlikely that there will be a special increase (But probably if the idea is really interesting, the increase will be noticeable)
I apologize for the banal questions, but I very often watch how many successful people talk about how they achieved their success. About how they had that very idea for a million and they fired with it. But practically none of them told how they advertised it.
Now my plan is to do SEO of the site and look for investments in the future.
Do you have any advice regarding this? Websites can't go viral on their own. How do projects achieve that people start to score on Skype and switch to a new, popular "discord" (under discord, I will introduce any application that at some point becomes so popular that everyone is already sitting on it, although yesterday about no one knew anything about it)
Understand my question correctly. I'm not cunningly invented and I don't ask the secret of success (Although.... I probably ask)
But I'm very interested in how projects begin to "virus" hard on the network. Answers marked "just advertising" will not work, because it is very predictable.

Answer 1

You first implement the idea, and then worry about growth. And then some weakling sits on the couch and wonders: what will happen when he pumps up. Will he take first place in the weightlifting competition or only third place.
And why do you need growth now? If tomorrow a million-strong crowd comes to your site, will your server serve this crowd? Do you have money for a bunch of powerful servers, for traffic, for full-time admins?

Answer 2

Smart people hire specialists for this and pay them big money. In particular - the department of marketing, advertising, sales and so on.
Often advertising and promotion of a product at a price tag is MORE EXPENSIVE than its development.

Answer 3

This is the answer!
Investors' investment in the market promotion of the project they need is like sowing grain.
People are hired who enter into contracts with large PR agencies and away they go, and then they constantly collect a hefty percentage of the application’s income or, even worse, all the interesting metrics (BigData), which they then resell further.

Answer 4

A good product that solves real problems / satisfies the real needs of the target audience + good promotion and PR + luck and luck.
Now, after this catastrophe and the economic crisis, all the "husks" in the form of "tweets for cats", "Facebook killers" and "social network applications for rating photos with filters" will fly off, more precisely, have already flown down, and what is really needed will remain, for which people are willing to pay money, waste time.
Does your "million dollar idea" solve a real problem/need?
