Website promotion to the top on demand, what is needed, and what will be the final price?

Question

contextual advertising

A person needed a sharp landing page (lp), but the question is in visits and advertising.
What do you need so that at the request "Buy plastic pens in Tyumen", a specific site would issue?
A person is interested in the price, explain what will happen if you invest minimally, or engage in promotion without investments at all, you are interested in the outcomes of such a situation, I am a person who does not understand advertising and promotion, I think that under the condition "No investment / Minimum" nothing good will come of it.
And yet, as I know, the progress of site promotion is also affected by its lifetime, is it so?

Answer 1

"Without attachments / Minimum" nothing good will come of it.

quite naturally, few people will be able to simply learn about your site by telepathy, and in search engines (ps) site promotion occurs according to algorithms that take into account many factors, including: visits, interest, usefulness, compliance with the request, updating information, lifetime and much more (read the recommendations ps). As you can see, it is unlikely that these factors will be provided quickly and cheaply.
Yes, in ps there is a minimum period for which you can gain a certain cap of the rating, if this happens faster, then most likely the site is "cheat", with the risk of being out of the index for good, or at least for a long time.

Answer 2

Since a person needed it abruptly, does it mean that he wants the result "here and now"? For the result to be immediately it is in Yandex.Direct, but this is not about "investing minimally / without investments." Without investments, this is a relatively long way.

Answer 3

study , especially the comments

Answer 4

I can say without looking that with this request alone you can bring a thematic site to the top in 2-3 months with a budget of up to 500 rubles. But that won't do much.
