What is a SEO expert witness?
SEO expert witness: A SEO expert witness provides technical analysis to form an opinion on search engine optimization (SEO), the process of driving traffic to websites from organic search results on search engines.
Typically, this means having a website rank well in search engine results for certain keywords people enter. A SEO expert witness is also known as a Search Engine Optimization expert witness.

There are various SEO tactics, methods, and strategies commonly used to generate this website traffic from search engine results, which involve both technical and marketing elements.

A SEO expert witness can examine various aspects of SEO, including whether SEO standard practices were followed, whether SEO practices were used to reduce traffic to another website, and the effect of SEO efforts, among other issues.
