SEO Expert Witness for Attorneys: Independent Analysis, Reports and Testimony
When a case turns on Google rankings, organic traffic, backlinks or how a search engine treats a website, the court needs someone who can read that evidence and explain it in plain English. I have practiced search engine optimization since 2004 and have testified in federal court as a retained SEO expert.

What Is an SEO Expert Witness?
An SEO expert witness is an independent search engine optimization specialist retained in a legal matter to analyze search evidence, form opinions about it, and explain those opinions to a judge, jury or arbitrator. The work usually takes three forms: a written expert report, deposition testimony, and testimony at a hearing or trial. Attorneys also look for this role under other names: search engine optimization expert witness, search engine expert witness, or more broadly a digital marketing, online marketing or internet marketing expert witness.
Counsel retains one when a disputed fact lives in search data. Did rankings or organic traffic fall, and when? Were the links pointing at a website natural? Did an agency's SEO work meet accepted practice? How do Google's published policies treat the conduct at issue? Arguing the case is counsel's job. The expert's job is to say what the data shows, how reliable it is, and where it stops.
I have done this work in the field since June 2004, in-house and as a consultant, including enterprise SEO at Walgreens across more than 9,000 store locations. In 2026 I wrote an expert report and testified in person, on direct and cross-examination, in a U.S. District Court. I still practice SEO every week. That matters, because the tools, the data sources and Google's documentation change constantly, and testimony should come from someone who uses them.
Cases Where an SEO Expert Witness Helps
These are the disputes where search evidence most often decides a fact. If yours is close to one of them, the question is probably answerable from data.
Negative SEO and toxic backlink claims
Allegations that someone pointed spam links at a website to damage its rankings. I examine the backlink profile directly: first-seen dates, link velocity, anchor text, the linking domains and their registration records, and whether the pattern is consistent with links earned naturally.
Lost rankings and organic traffic
Whether traffic fell, on what date, and which explanation fits the evidence: a site change, a migration, a Google update, seasonality, a tracking failure or the conduct alleged. This is the forensic method I use in SEO recovery work, held to a litigation standard.
SEO agency and vendor disputes
Breach of contract and negligence claims over SEO services. I compare what was promised with what was delivered, and measure the work against Google Search Essentials, Google's spam policies and what a competent practitioner would have done at the time.
Website redesigns and migrations that erased traffic
Disputes with a developer or agency after a relaunch. Redirect maps, URL changes, rendering and indexation records usually show what broke and when.
Trademark, keyword and brand search disputes
How a brand name appears in organic results, which pages rank for it, and how titles, content and links were used to target it. I describe the search mechanics and the data. Questions of consumer confusion belong to survey experts and the court.
Online reputation and defamation matters
How visible a page or statement was in search: its ranking history, the queries that surfaced it, indexation dates and estimated exposure over time.
Google penalties, spam policies and deindexing
Whether a manual action or an algorithmic demotion occurred, what Google's documentation says about the practice involved, and what it did to the site's visibility.
Local search and Google Business Profile disputes
Listing ownership, suspensions, duplicate or fake listings, review manipulation and map visibility, for a business with one location or thousands.
What Search Evidence Can Show, and Where It Stops
Every opinion I give is tied to a data source and its limits. This table is the short version of how I approach the six questions attorneys bring most often.
| Question in dispute | Evidence examined | What it can establish | Where it stops |
|---|---|---|---|
| Did organic traffic fall, and when? | Google Search Console exports, Google Analytics, server logs | The date, the size of the change, and the pages and queries affected | Search Console keeps 16 months of performance data, so early preservation matters. Tracking changes have to be ruled out first. |
| Were the links natural? | Backlink indexes such as Ahrefs, Semrush and Majestic, the Search Console links report, domain registration records | Timing, velocity, anchor text patterns and signs of common ownership among linking sites | Third-party indexes are samples of the web. Link data alone rarely identifies who built the links. |
| What caused the drop? | Site change logs, archived copies of pages, Google's published update history, competitor visibility data | Whether the timing fits a site change, a Google update or the conduct alleged, with alternative causes tested | Google does not publish its ranking systems in full. Causation is stated as what the evidence is and is not consistent with. |
| Did the SEO work meet accepted practice? | The contract and scope, deliverables, tickets, reports, Google Search Essentials and spam policies | What was done, when, and how it compares with the contract and Google's published guidance | SEO has no licensing body. The standard is argued from documented industry practice at the time of the work. |
| How visible was a page or statement? | Ranking history, impression data, indexation records | Position over time, the queries involved and approximate exposure | Third-party traffic numbers are estimates. First-party data is stronger whenever it can be obtained. |
| What was the lost traffic worth? | Organic sessions matched to conversion and revenue records | The search inputs a damages calculation needs | I do not calculate damages. A financial expert does that, using these inputs. |
For Google's own positions I rely on Google Search Essentials and Google's spam policies. My reports are written to the standards in Federal Rule of Evidence 702 and Federal Rule of Civil Procedure 26.
How an Engagement Works
Five steps, from the first email to the witness stand. Counsel can stop after any of them.
01
Conflict check and first call
Send the case caption and the parties. Once conflicts are cleared, counsel walks me through the search question. If I do not think the evidence will support the opinion you are hoping for, you hear that on this call.
02
Preliminary review
A scoped first look at the available data, usually as a consulting expert. You learn what the evidence is likely to show before deciding whether to designate a testifying expert.
03
Independent analysis
I pull the data myself and check one tool against another, because every SEO tool is an estimate. I read the filings from both sides so I know what is claimed and what is not.
04
Written expert report
Each opinion with its basis and reasons, the facts and data considered, exhibits, my qualifications and my compensation, organized to meet Federal Rule of Civil Procedure 26(a)(2)(B) or the state equivalent. Rebuttal reports on an opposing expert's work get the same discipline.
05
Deposition and testimony
Preparation with counsel, then testimony at deposition, hearing or trial, including cross-examination. Plain English, no jargon, and answers to the question that was asked.
Qualifications
The short version. A full CV and a list of prior testimony go to counsel on request.
22 years of hands-on SEO practice, beginning in June 2004.
Federal court testimony in person in 2026, on direct and cross-examination, following a written expert report.
9,000+ locations in the Walgreens store network, where I worked on enterprise and local SEO as a senior analyst and then SEO manager.
Published in Search Engine Land (2017) on SEO and brand protection, and a panelist at Localogy (2018).
Case names are not listed on this page. Prior testimony is disclosed to counsel as Rule 26 requires.
Who Retains Me and What to Expect
Plaintiffs and defendants
Attorneys for either side retain me. The opinions do not change with the side: I report what the data supports, including the parts that do not help the party paying for the work.
Testifying or consulting
Some matters need a testifying expert with a report and a deposition. Others need a consulting expert behind the scenes to pressure-test a claim, frame discovery requests for search data, or evaluate the other side's expert report.
What I do not opine on
I do not offer legal conclusions and I do not calculate damages. My opinions stay inside organic search, local search, content, links and web analytics. When a matter needs paid advertising or survey expertise, I say so and step aside on that issue.
Fees
Work is billed hourly for review, analysis, report writing, preparation and testimony, with a retainer at engagement. The fee schedule arrives with the conflict check. Payment never depends on the outcome of a case.
Chicago and nationwide
My office is in Chicago, close to the federal courthouse and the Daley Center. I take matters in federal and state courts across the United States, and I can appear remotely where the court allows it.
