Cheat traffic from PS - useless or useful?

Question

Search Engine Optimization

Does it make sense to buy traffic from the PS for certain requests?
That is, they bought, for example, 5-6k traffic and stretched it for a month.
Do you have experience with similar services?
What does it threaten?

PS The same Google stores the same positions of the site for certain queries, if the traffic has increased, but the position has not changed - can this mean something?

Answer 1

If you do not understand this, then there is no point in buying, if you understand it yourself and drive this traffic
