Evidence and testimony
What the claim is

Digital Marketing Disputes

Ten kinds of dispute, each labelled with what actually has to be proven: the standard of care, causation, or quantum.

Overview

Nobody has a social media problem. They have a claim, with elements, and one of those elements is the one actually in dispute. Two matters can concern the same advertising account in the same months and have almost nothing in common: in one the parties agree what was spent and disagree about whether the work met an obligation; in the other they agree the work was poor and disagree about whether it caused the decline; in a third liability is effectively conceded and everything turns on a number. The records that matter are different in each, and so is the expert’s assignment.

That is what this category is for. The channel pages describe what records exist. These pages describe what has to be proven, and therefore which of those records is worth the time it takes to get.

Performance and contract — what was promised, what was delivered

Agency and consultant disputes, scope and deliverable disputes, and performance-based compensation. The contested element here is usually the standard of care, and this is where the honest answer has to come first: digital marketing has no general licensure requirement, no mandatory body of practice, and no body that can bar anyone from practicing. The advertiser-side trade body publishes a contract template and expressly calls it a starting point; the agency-side trade body stated in July 2024 that it does not recognize that body’s templates as industry standards. The Media Rating Council audits measurement services rather than practitioners. Vendor certifications are product exams.

So a claim built on unanchored assertions about industry standards is a claim with a soft center. What holds instead: the contract and the statement of work, which is what the parties actually agreed; the platform’s own published rules, which can establish that a specific act was prohibited by the system the work was performed in; objectively verifiable facts of execution — tracking that never fired, a tag removed on a datable day, spend billed that does not match spend delivered; and internal inconsistency between a party’s own reporting and the platform’s record. Compensation structure shapes the dispute too. A percentage of spend produces one argument, a fixed fee against a scope another, and an incentive tied to a metric produces the most technical one of all, because the settings that generate that metric are themselves logged and datable.

Fraud and abuse — traffic and conduct that was not what it appeared

Click fraud and invalid traffic, affiliate and incentive fraud, bot traffic and impression fraud. The contested element is generally causation, and the evidence is unusually asymmetric. An advertiser’s own account data shows what was charged and what a platform later credited back as invalid; it does not identify who generated a click, and it cannot. Platform-side filtering reports show what a platform’s systems rejected — not what they missed — and the detection logic is not published, which is the first observation an opposing expert will make and should therefore be the first sentence of any report that relies on it.

What can be built is a pattern: timing distributions, source and placement concentration, device and network signals where they are available, conversion behavior that is inconsistent with the traffic that produced it, and the reconciliation between what was billed and what was credited. Those are records. The identity of the person or system behind the traffic usually is not, and where a matter requires it, it requires a different kind of expert alongside this one.

Claims and conduct — what was said publicly, and to whom

False and deceptive advertising, and trademark use in advertising. Here the evidentiary problem is preservation rather than complexity. The statement at issue was a piece of creative, a landing page, a product listing, a disclosure and its placement, or a keyword and the ad it triggered — and every one of those is transient. Ad libraries, archived pages, creative approval records, the account’s own history of ad copy, and version histories of the pages behind the ads are what remains, and how much remains depends almost entirely on how early someone thought to capture it.

Precision about authority matters more in this group than anywhere else on the site, because two frequently cited decisions in this area are routinely mis-described in trade writing — one is an antitrust decision quoted as if it settled trademark law, and one had an opinion superseded by an amended opinion that reached a different result, with both still circulating. Pages here state what was actually decided, by which court, in which year, or they say nothing.

Loss and quantification — what it cost, and how the number is built

Traffic and revenue loss, and marketing damages models. When liability is largely conceded, the entire matter becomes the number, and the number is where marketing analysis is weakest. A damages model has to travel from impressions to clicks to sessions to orders to dollars, and every one of those joints is a separate assumption that has to be supported. Out-of-pocket loss — money paid for something that was not delivered — is the category the record most often supports, because it is arithmetic drawn from independent sources. Lost profits require a but-for world, and constructing one means isolating the effect of the conduct from seasonality, competition, pricing, inventory, platform changes and everything else moving at the same time.

This is also the group where a marketing expert should hand part of the work to someone else. Quantification of business loss is an economist’s discipline; what a marketing expert supplies is the input layer and its limits — what the traffic and conversion records establish, what they estimate, and where they stop.

Why this layer exists at all

Search demand for expert witnesses in this field is almost entirely channel-shaped: people type the platform or the discipline followed by the phrase, and essentially nobody types the name of a claim. This category is therefore not built for search. It is built for the decision counsel is actually making, which is whether an expert can help with the element that is in dispute, and what to ask that expert to do.

Reading advice, then. If you know which platform the dispute came out of but not what to ask for, start in the channel category and come here second. If you know the claim but not which records reach it, start here. Either way the pairing is what matters: a click fraud claim in paid search and a click fraud claim in affiliate traffic are different engagements with different record sets, and the matter page tells you what has to be proven while the channel page tells you what exists to prove it with. Neither layer, on its own, tells you whether the analysis will support the conclusion someone hopes for. That is settled by the records, and often it is not settled in the way the party who commissioned the work expected.
