Summary

We have launched "modeled conversions" for Search Ads conversion tracking.
Modeled conversions are conversions that are estimated by building a model with measurable data about conversions that cannot be measured directly with Yahoo! JAPAN Ads.
Recently, iOS and other platform regulations have made it increasingly difficult to measure conversions from ads.
Complementing non-measurable conversions with modeled conversions allows for a more accurate ad evaluation.
As conversion data increases, you can expect improvements in ad delivery, ad effectiveness optimization, and bid strategy accuracy.

Notes

• The modeled conversions you get are combined with your regular conversions. You cannot select only modeled conversions or exclude them from the total number of conversions.
• Only web page conversions are estimated. App conversions and other services are not eligible.
