SEO Expert Witness Experience Counts

In order to be an effective, honest, and authoritative search engine optimization expert witness, recent experience in the search engine optimization and digital marketing industry is a must. An search engine optimization professional, if used as an independent witness in legal issues, must have actually practiced search marketing in multiple capacities. Mr. Hartzer started his website marketing and search engine optimization career in the mid-1990s, even before Google existed. He was optimizing web pages and driving traffic to websites from search engines before Google was born.

SEO Expert Must Know Their Subject

Not only should a search engine optimization witness know search engine optimization methods, tactics, and strategies inside and out, that search engine optimization expert needs to have actually used both white-hat search engine optimization, gray hat search engine optimization, and even black hat search engine optimization techniques. They need to fully understand and be able to explain web server technologies, the techniques that companies may use to manipulate their positions in the search engine results, and the ins and outs of negative SEO. At the same, time, they need to understand all parts of online marketing, including pay per click (PPC) advertising like Google Ads, as well as other forms of online advertising. Mr. Hartzer is that person, that search and digital marketing industry professional you’re looking for.

Not only does expertise need to be in the area of marketing and advertising, there are other related topics that are relevant that an expert witness in the SEO and internet marketing fields must know understand fully. These include, but are not limited to:

  • Trademark Infringement
  • Intellectual Property
  • Search Engine Results
  • PPC (Pay Per Click) and Internet Advertising
  • Domain Names
  • Defamation
  • Damages

While Mr. Hartzer does not specifically claim to be an expert at all of these topics, such as trademark infringement, IP, defamation and damages, each of these have played a big role in the legal cases in which he’s been involved over the past several years. For example, in one particular case, violations related to the registration and use of internet domain names was one of the disputes in a case. Mr. Hartzer is an domain name expert, and regularly consults with clients regarding domains. He provided testimony and his professional opinion regarding the registration of domains. In more than one legal case, infringement was involved in the registering of domain names.

1. Trademark Infringement, IP, and the Internet

Oftentimes, questions arise regarding trademark infringement and the search results or trademark infringement as it relates to Google Ads, which can include violations related to domain names, search results (both organic web page results and online advertising such as Pay Per Click). The Google website has established very specific guidelines and policies. Any violations, disputes, or questions need to be addressed directly with the company using the form that they provide. At the same time, while these policies exist, oftentimes this is not enough to resolve disputes. So, litigation is required to resolve the dispute and award money.

2. Search Engine Results Include Many Parts

Google, Bing, and Yahoo results include many different parts, including paid or sponsored text advertising, online shopping ads, local maps listings, local business listings, and the natural or organic listings. In many cases where Mr. Hartzer has served as a witness in the litigation, he provided detailed explanations of information provided on web results that included screen captures as well as written explanations of how search works. In some cases, he has provided his expertise and professional opinion to explain how results are influenced by over 1,000 ranking factors. Mr. Hartzer has also been asked while being deposed about his use of custom search on websites.

3. PPC Related Lawsuits and Litigation

Disputes and litigants in cases can ask for compensation because of the improper use of Pay Per Click advertising. For example, competitors who advertise using Google Ads or other online advertising (such as ads on can cause cause confusion when bidding on another company’s trademarked keywords. Keywords that include a company name, trademark, or other similar keywords such as misspellings can confuse internet users, driving users to their website when the user thinks that they’re clicking on a advertiser’s ad. Damages have been awarded as a result of litigation in the past involving the improper use of online ads. Mr. Hartzer can testify and provide expert reports involving internet and online advertising–he is certified in Google Ads as well as many of their products and services.

4. Internet Defamation and Damages

Complex internet legal cases involving search results, infringement, and advertising can result in compensation being assigned to companies and individuals because of character issues that occurred on the internet. Mr. Hartzer has a professional background involving (online reputation) as it relates to damages. In one case in particular, he provided his opinion in regards to the process involved in removing content from the website pages. Other opinions that he has provided clients were related to the costs involved with influencing the an engine’s results so that it would be more difficult to find “negative” web pages.

5. SEO Expert Witness Qualifications & Proof

Mr. Hartzer has written over 1,000 articles and blog posts written on the subject of websites, domain names, website design, webmaster issues, website and internet marketing.

Full-Time Expert Witnesses

He has provided his industry expertise to companies worldwide, from small businesses to Fortune 100 companies during his career. He has even provided digital marketing and search engine optimization services in 9 different languages. He is Google Certified, and a Google Ads (formerly Google AdWords) Certified Individual.

SEO and Digital Marketing is Difficult

Search Engine Optimization and digital marketing used to be, back in the 1990s, a lot easier to perform. You simply optimized the web pages that you wanted to rank by writing title tags, writing meta tags, and added keywords to your web page. However, over the years, Mr. Hartzer has been seen it all–the changes and complexities that have evolved. Now, internet search engines use literally thousands of signals to decide how to rank one particular web page in their results. With customization, privacy, and artificial intelligence having been added in the last few years, it makes it increasingly difficult to properly optimize one web page and make it show up well in the search results.

Not a Full-Time Internet Marketing or SEO Expert Witness

Mr. Hartzer isn’t a full-time witness, which actually is a good thing. Someone who is a full-time witness doesn’t have the time to keep up with all of the search algorithm changes and updates. That is imperative for this type of job. As a full-time Internet Marketer, SEO expert, and Domain Name Expert first, and part time witness, second, Mr. Hartzer is familiar with all of these issues–it’s his job to keep up with the changes in the industry. He is, however, able to fully explain all of these changes, updates, and search ranking issues to anyone–especially if relied upon as an expert. Bill uses his previous technical writing background (he wrote software manuals on IBM mainframe computers back in the early 1990s) to explain technical search and website issues to everyone. Even those without a technical background. Oftentimes, web server, IP address, and domain registration issues are involved in Search Engine Optimization litigation, and Mr. Hartzer has the expertise to research, analyze, and provide professional opinions on these issues.

As a formally trained technical writer (Mr. Hartzer minored in technical writing in college), Mr. Hartzer’s reports are second-to-none, they’re simply outstanding because of his technical writing expertise. His reports are thorough, well-written, and technically accurate–everything Counsel would want in a report.

Expert Witness and Expert Witnessing Experience

Many legal cases involve a lot more than just search engine optimization. In fact, all of the cases at the United States Federal level that Mr. Hartzer has been involved with involved more than just internet marketing or website issues. They involved issues such as social media, domain names, website issues, website coding issues, and even online reputation management issues. Mr. Hartzer’s experience and knowledge is quite often helpful when it comes to these other topics that are a part of complex legal cases.

Mr. Hartzer provides online reputation management services, and has been providing these services for over 10 years. He has the proven experience to research, talk, write about, and provide his professional opinions on these issues, especially in the areas of SEO.
