Is it worth creating a copy of a Yandex.Direct campaign with quotes?

Question

contextual advertising

Is it worth creating a copy of an advertising campaign in Yandex Direct with all key queries placed in quotation marks and running it in parallel with the main campaign?
Has anyone tested?

Answer 1

It’s worth it for more control and in some places a much better result, well, check the same wordstat in quotes.

Answer 2

From experience, it is better to do only with high-frequency queries and in the main campaign. For the rest, there will simply be practically no impressions with strict compliance.
