An important indicator for operating dynamic ads is the "match rate between tags and data feeds."
The "match rate between tags and data feeds" is an indicator used to check whether the products and services listed on a website are correctly reflected in the linked data feed, and is defined as kazakhstan phone number material " the number of product IDs in the data feed that match the product IDs sent from the tags."
for example,
Number of hits for product detail page tag: 100
Number of product IDs on the data feed that match ①: 80
Match rate between product detail page tag and data feed: 80%
Something like that.
The recommendation engine of dynamic ads matches the product information for which the tag was fired (≒ viewed by the user) with the product information in the data feed, learns from the various information contained in the data feed such as price and category, and reflects it in the ad creative. Therefore, increasing the matching rate is important for promoting machine learning and improving ad performance.
So, this time we will introduce measures to deal with the "mismatch between tags and data feeds" in dynamic ads in the form of a Yes/No chart.

Yes/No Chart
The basic premise is that the higher the match rate, the better, but it doesn’t necessarily have to be 100% and most dynamic ad platforms will function well even with a certain degree of mismatch rate.
For reference, the specifications of Criteo and RTB House state that ad delivery cannot be started or resumed if the mismatch rate exceeds 30%, so this can be considered the minimum standard. (Information as of October 2020)
Next, we'll use a Yes/No chart to show you how to identify the source of discrepancies.
The diagram below starts with the question, "Is the match rate between tags and data feeds 0%?" and divides the answers into Yes and No. It then divides the possible causes of discrepancies into "data feeds" and "tags."
