What happens to Shirofune's behavior when I'm setting up automatic bids (bid strategies) for media ("Maximize conversions", "Target bids")? Also, please tell us about other bidding strategies.

For the "maximize conversion number (value)" and "target conversion unit price (ROAS)" set for each advertising medium, the automatic bidding setting of the medium will be used as it is. In that case, Shirofune will adjust the daily campaign budget and target unit price while using automatic bidding of media to maximize the results within the budget set by Shirofune.

In addition, when set to "Target conversion unit price (ROAS)", the target unit price will be lowered if the delivery pace is fast and the target unit price will be increased if the delivery pace is slow against the Shirofune set budget.
(However, the frequency and degree will be fairly modest, in line with media recommendations)

The response to other bidding strategies is as follows.

・ "Extended cost per click"
→ The media bid strategy is applied as it is, and the bid unit price of individual keywords and user list
Shirofune automatically optimizes the bid adjustment ratio for each device every day.

* Individual click unit price will be changed to extended click unit price.

・ "Maximize the number of clicks"

→ The media bidding strategy will be applied as it is, and only the daily budget will be adjusted by Shirofune.

(However, if there is a search campaign and conversions, the extended cost per click will be added.

Switch, bids for individual keywords, bid adjustment ratios for each device, etc. in Shirofune
We aim to improve the effect by switching to the form of automatic optimization)

・ "Target impression share / posted at the top of the page"
→ Switch to extended CPC bids for individual keywords and user list bids
Shirofune automatically optimizes the bid adjustment ratio for each device every day.
(In the future, we are considering that Shirofune can adjust only the daily budget with this setting.)

* The same applies when a portfolio bidding strategy is set.

* When Shirofune changes the setting to the extended CPC, it will be changed to "Individual CPC" once to make it easier to control the bid after the change, and then it will be changed to "Extended CPC" a little later. ..
