As technology continues to evolve, so do the complexities of lawsuits involving online advertising, such as Google Ads, Facebook Ads, or ads on YouTube. In a lawsuit involving trademark infringement due to online advertising, an attorney may benefit from hiring a skilled expert witness with deep expertise in marketing and how online advertising works at both a quantitative and qualitative level. 
In this essay, we will discuss why an attorney should consider hiring an expert witness in a complex lawsuit involving trademark infringement due to online advertising, as well as list three characteristics that an attorney should look for in an expert witness on the technical aspects of online advertising.
Firstly, an expert witness can provide a technical understanding of the online advertising landscape. A skilled expert witness can explain to the court how online advertising works, how it is targeted to specific audiences, and how it can be used to promote products or services. They can also provide insight into how online advertising platforms such as Google Ads, Facebook Ads, or YouTube Ads operate and how they are used by businesses. This knowledge can be crucial in a lawsuit involving trademark infringement, where the use of online advertising may be a key factor in determining whether or not the infringement occurred.
Secondly, an expert witness can provide a quantitative analysis of the online advertising campaign in question. They can analyze data from the advertising platforms and provide metrics such as click-through rates, impressions, and conversions. This analysis can help the court determine whether the advertising campaign was successful or not, as well as provide insight into the impact of the advertising on the target audience. This quantitative analysis can be used to support the attorney’s case or provide a rebuttal to the opposing side’s arguments.
Thirdly, an expert witness can provide a qualitative analysis of the online advertising campaign in question. They can analyze the messaging and creative aspects of the advertising campaign and provide insight into how it may have influenced the target audience. This analysis can be used to determine whether the advertising campaign was misleading or deceptive, and whether it infringed on the trademark rights of the opposing party. The expert witness can provide an opinion on whether the advertising campaign was likely to cause confusion in the minds of the target audience and whether it was likely to lead to trademark infringement.
When looking for an expert witness on the technical aspects of online advertising, there are several characteristics that an attorney should look for:
- Industry experience: The expert witness should have deep experience in the online advertising industry and should have a thorough understanding of how online advertising platforms work. They should have experience in creating, managing, and analyzing online advertising campaigns and should be familiar with the latest trends and best practices in the industry.
- Technical knowledge: The expert witness should have a strong technical background and should be able to provide a quantitative and qualitative analysis of the online advertising campaign in question.

- Credibility: The expert witness should be credible and have a track record of providing expert testimony in similar cases. They should be able to communicate their analysis in a clear and concise manner and should be able to explain technical concepts to the court in a way that is easy to understand.
