A new dynamic parameter for ad links has appeared this week – {coef_goal_context_id}. Using it, you can get valuable conversion statistics for ads with retargeting lists and corresponding bid adjustments. For example, if you targeted users who added products to their cart without purchasing them, and raised your bids for this group by 40%, the Yandex.Metrica URL parameter report will show you the number of conversions for these ads, as well as more detailed information — gender, device type, etc. — about each user who visits the site.
To find out more about adding this parameter to links in your ads, please read the help section.
