In order to find out a drop in cart sessions from the Summary trend, you need to first choose a date range where you want to investigate for a drop. Eg: choose the last 7-days from the date range filter and then plot cart sessions from the summary graph dropdown. In case the trend for the cart sessions line is continuously decreasing, there is a drop.
What should you do next?
Start by investigating the bottom of the funnel – ad spends, impressions & visits. Plot each of these metrics and in case there is a proportional drop in any, then refer the FAQ for the respective metric.
If all the above metrics are fine then this means people are interacting with our ads and landing on our website but are not adding a lot of products to the cart. Check if the products promoted are in stock, audiences targeted are irrelevant
