Invalid Traffic

What is Invalid Traffic? 

Invalid traffic refers to any traffic that is not legitimate or valid, such as bots, spiders, or fake clicks. It can also include traffic from sources that are not authorized to access a website or application, such as unauthorized IP addresses or devices. Valid traffic, on the other hand, refers to traffic that is legitimate and comes from legitimate sources, such as human users. Understanding the difference between valid and invalid traffic is important for measuring website traffic and analyzing user behavior. 

Bidding on this traffic is wasteful for both advertisers and retailers for several reasons: 

  1. Cost Efficiency: Invalid traffic, also known as click fraud or non-human traffic, can waste advertisers' budgets by generating fake clicks or impressions. By identifying and filtering out invalid traffic, advertisers can ensure their advertising spend is used effectively and reaches real potential customers. 

  1. Accurate Performance Metrics: Invalid traffic can skew performance metrics, making it difficult for advertisers to measure the true impact and success of their advertising campaigns. By eliminating invalid traffic, advertisers can obtain more accurate data on click-through rates, conversions, and other key performance indicators. 

  1. Protecting Brand Reputation: Invalid traffic can harm an advertiser's brand reputation. For example, if an ad is shown on websites involved in fraudulent activities or in a context that is not aligned with the advertiser's values, it can negatively impact their brand image. Avoiding invalid traffic helps advertisers maintain a positive and trustworthy brand presence. 

  1. Ad Fraud Prevention: Invalid traffic is often associated with ad fraud, where individuals or automated systems manipulate ad impressions or clicks to generate illegitimate revenue. Advertisers want to avoid falling victim to ad fraud schemes, which can result in significant financial losses. 

  1. Ensuring Targeted Reach: Advertisers want to reach their intended audience and maximize the effectiveness of their campaigns. By avoiding invalid traffic, they can focus on delivering their ads to real users who are more likely to engage with their brand or make a purchase. 

To combat invalid traffic, Criteo gives advertisers various fraud prevention options to work with.
