Should I choose manual bid management without restrictions in Yandex.Direct?

Question

contextual advertising

Today, a Yandex.Direct employee sent me a letter about my advertising company, which contained the following paragraph:

We noticed that you are using the "Show in the smallest possible position" setting. Since September 1, 2015, the logic of the auction in Yandex.Direct has changed (we switched from the "second price" auction to the VCG auction), and this setting has ceased to justify itself. Using it, you limit not only the cost of a click, but also the number of clicks on ads. We recommend that you choose the "Manual bid management" strategy without restrictions.

In the settings of the advertising company, I have "Show at the lowest possible position in special placement and grenades." It turns out that Yandex recommends that I disable this option, but from this letter I still don’t understand why it would be better for me. Now I have max. the cost per click is 50 rubles, but for most of the requests I need, I display them in the places that suit me and the transitions go.
Why do they say that such a setting has ceased to justify itself?

By disabling the “Show in the lowest possible position” option, you can not only
pay the best price for a click to your site, but also get the maximum number of clicks
from interested users.

What does optimal price mean? The optimal price for me or for Yandex? Yandex, on the other hand, is more profitable with high prices for clicks in a competitive category.

In addition, it does not have the best effect on the manageability of placement - if you are not the only one using this setting of the "Manual bid management" strategy in a block, ads are ranked randomly, and it is easier for competitors to beat you in the auction.

This is also incomprehensible. In general, a lot of words, but nothing understandable.
Should I pay attention to this or is Yandex trying to take more money from me?

Answer 1

In general, Yandex is right. Thanks to the new VCG auction, competitors' bids and previous position bids no longer play such a role. As a result, you can get more clicks for the same bet.

Yandex, of course, also benefits from this - after all, the more clicks you get, the more you spend in total. But if the amount of traffic is important to you, then by removing this setting you will get more clicks at about the same cost per click.
