PART 1 OF 7
Disappointing results are not the same as negligence
Marketing campaigns fail for many reasons that have nothing to do with professional fault: a market shifts, a competitor outspends, a search engine changes how it ranks pages, or the product simply does not convert. A client who paid an agency for a year and saw flat revenue may feel wronged, but a court needs something more specific than a bad outcome. It needs to know whether the agency's choices fell below what a reasonable practitioner would have done with the same information, budget and timeline.
That question is where a digital marketing expert witness is usually brought in. The work is to reconstruct what the agency actually did, compare it with the norms of the discipline at the time, and separate ordinary market risk from avoidable error.

What the contract and the scope of work really promised
The first step is almost always documentary. Statements of work, proposals, monthly reports and email threads define what the agency undertook. Many disputes turn out to be scope disagreements dressed up as performance claims.
- Was the agency hired for strategy, execution, or both?
- Were deliverables defined as activities (posts, ads, pages) or as outcomes (leads, revenue)?
- Who controlled the budget, the landing pages and the tracking setup?
- Did the client approve the changes it now objects to?
An agency that delivered every contracted activity on time may still have exercised poor judgement, but the analysis has to start from what was actually promised rather than from what the client hoped would happen.

Reconstructing the work from platform records
Marketing platforms keep detailed histories, and those histories are often more reliable than anyone's recollection. Advertising accounts record bid and budget changes, analytics properties record configuration edits, and content systems record revisions. Together they show whether the agency was actively managing the account or letting it run on autopilot.
Common findings include tracking that was never configured correctly, so reported conversions did not match real leads; campaigns paused or restructured without explanation; and reporting that emphasised vanity metrics while the measures the client cared about declined. Each of these is a factual finding that can be shown from the record, not an opinion about taste.

Why practitioner experience matters in these cases
Standard-of-care testimony is only as credible as the witness's familiarity with how the work is really done. Dan Stratford has worked in digital marketing since the mid-1990s, with 29 years in practice, including senior roles such as Chief Marketing Officer and Director of Performance Marketing, and as the founder of a digital marketing agency that served clients in legal, insurance, technology, SaaS, home services, education and eCommerce before it was sold in 2015. He holds a BS Biology, Rockhurst University; MBA, Regis University.
That agency-side background is relevant because agency disputes often hinge on operational realities: how account handoffs happen, what monthly reporting normally contains, and what a reasonable response to a performance drop looks like. An independent profile with his credentials is available as Dan Stratford on USA Attorney Guide, a third-party legal directory listing.

Law firms as both litigants and marketing clients
Law firms are frequent agency clients themselves, and some agency disputes involve a firm's own marketing programme. The same evaluation applies: what was promised, what was done, and whether the approach was reasonable for a professional-services business with long sales cycles and strict advertising rules. For firms reviewing their own approach outside of any dispute, an article on how law firms can build a sustainable digital marketing strategy offers general further reading on planning marketing that holds up over time.
PART 6 OF 7
What counsel should gather early
- The full contract, every statement of work, and any amendments or change orders.
- Admin access or exports from ad accounts, analytics properties and the website CMS.
- All monthly or quarterly reports exactly as they were delivered.
- Internal client records of leads, sales and revenue for the same period.
- Correspondence showing approvals, objections and requests for changes.
Account access is the item most often lost. Once an agency relationship ends, logins are revoked and change histories can become hard to retrieve, so preservation requests should go out as early as possible.
PART 7 OF 7
Separating market conditions from agency decisions
The hardest part of most agency cases is causation. Even where an agency made poor choices, the client's results may have declined anyway because of seasonality, a pricing change, a new competitor or a search engine update. A careful analysis lines up the agency's documented actions with the performance data and with external events over the same period, then asks which explanation the timeline actually supports.
Comparison periods help. Performance before the engagement, during it, and after a new provider took over can show whether a decline tracked the agency's tenure or the wider market. Channel-level data helps too: if paid search collapsed while organic and referral traffic held steady, the explanation is more likely to sit inside the paid account than in the economy at large. None of this replaces judgement, but it keeps the opinion anchored to evidence that the other side can examine and test.
