Yandex.metrica/GA: how to track which product cards users go to (availability)?

Question

Google Analytics

Let's say we have an online store. Users from search and other sources go to product cards.
Items may or may not be in stock.
Objective: to understand the number of transitions / the ratio of transitions to cards that are available and which are not available.
How can such a problem be solved?

Answer 1

There are different ways to approach this task. But, for example, you can use Google Event Tracking .
On the product card page, put the following line in the Google Analytics code:
ga('send', 'event', 'Goods', 'AVAILABLE');
in which the parameter "AVAILABLE" is changed to the state of the goods at the time the user opens the card. Accordingly, in the statistics you get an event about the product at the time of the visit. Then you can summarize such statistics, segment and analyze.

Answer 2

In Yandex.metrics, you can use the "JavaScript event" target, while passing any user parameters.
For example, if the counter number is XXXX and the target ID is PRODUCT_VIEW, then:
Then in the report "Content -> Parameters of visits" there will be convenient graphs and tools for viewing ratios
