Algorithm for displaying ads in Yandex.Direct?

Question

contextual advertising

Greetings!

Suppose there is a company, it has 2 identical groups, each group has 1 identical ad. The difference is that "group 1" has a key - "buy an elephant" (with a quote operator), and the second group has a similar key, but without an operator.

Company:
- Group "group 1" with key - "buy elephant" (with quote operator).
-- Announcement "Announcement 1".
- Group "group 2" with the key - buy an elephant (without operators).
-- Announcement "Announcement 2".

The visitor types in a request - buy an elephant (without the quote operator), which ad will be shown to him (and if with an operator)?

Answer 1

Finally, I waited for a response from Yandex.Direct support.

If ads are created within different groups, ads will be selected according to the auction principle.

If the same ad contains the same query in quotes and without it ("buy an elephant" and buy an elephant), then the exact match (the user's request to buy an elephant) will always show for the keyword in quotes. Even if the CTR of the phrase in quotes is lower, and the cost of entering a position is higher. This only works within a group/declaration.
