Ad discrepancy is the difference in the number of ad impressions or requests reported by two or more parties involved in an advertising campaign. This can happen for a variety of reasons, including:

* **Different counting methodologies:** Publishers and advertisers may use different methods to count ad impressions or requests. For example, a publisher may count an impression as soon as an ad request is received, while an advertiser may only count an impression when an ad is actually displayed.

* **Technical issues:** Technical issues such as network latency, server timeouts, and ad blockers can all contribute to ad discrepancy.

* **Business practices:** Some business practices, such as ad stacking and ad fraud, can also lead to ad discrepancy.

Here are some of the most common causes of ad discrepancy:

* **Ad blockers:** Ad blockers can prevent ads from being displayed, which can lead to a discrepancy between the number of impressions reported by the publisher and the advertiser.

* **Latency:** Latency is the time it takes for an ad request to travel from the publisher's website to the advertiser's ad server. If latency is too high, it can lead to ad requests being dropped, which can also cause ad discrepancy.

* **Ad stacking:** Ad stacking is when multiple ads are displayed on the same page. This can lead to a discrepancy if the publisher and advertiser are counting impressions differently.

* **Ad fraud:** Ad fraud is the use of fraudulent methods to generate ad impressions or clicks. This can lead to a significant discrepancy between the number of impressions or clicks reported by the publisher and the advertiser.

There are a number of things that can be done to reduce ad discrepancy, including:

* **Using a common counting methodology:** Publishers and advertisers should agree on a common methodology for counting ad impressions or requests. This will help to ensure that both parties are reporting the same data.

* **Monitoring for technical issues:** Publishers and advertisers should monitor their systems for technical issues that could contribute to ad discrepancy. This includes things like network latency, server timeouts, and ad blockers.

* **Enforcing policies against ad fraud:** Publishers and advertisers should enforce policies against ad fraud. This will help to reduce the number of fraudulent impressions or clicks that are reported.

By understanding the causes of ad discrepancy and taking steps to reduce it, publishers and advertisers can ensure that they are getting an accurate picture of their ad performance.
