How these disputes start
A business hires an agency to improve search visibility. Months later traffic is flat or down, invoices have been paid, and the relationship ends badly. The client alleges non-performance or misrepresentation. The agency points to algorithm updates, competition, or the client's own website changes.
Both accounts can contain truth. The task in litigation is to test them against the documentary and technical record rather than accept either narrative. That means looking at the evidence the parties rely on, plus evidence neither side has put forward yet, such as archived copies of the site and the full search query data.
Start with the scope of work
The contract, proposals and sales materials define the baseline. Many SEO agreements describe activities - audits, content, link outreach, technical fixes - rather than outcomes. Others include ranking or traffic language that is more specific. Reading those documents alongside industry norms helps establish what a reasonable client would have understood was being purchased.
Then reconstruct what was delivered
- Work logs and reports: do they describe specific, verifiable tasks?
- Site history: archived versions show whether claimed changes were made, and when
- Content: was published content original, substantive and relevant, or thin and duplicated?
- Links: were acquired links plausible editorial placements or low-quality networks that carry risk?
- Rankings and traffic: how did visibility move relative to known algorithm updates and the client's own changes?
An analysis by a search engine optimization expert witness lines these sources up on one timeline, so that the cause of a decline can be attributed with evidence rather than argued from the outcome.
Content quality is part of the deliverable
Content is often the largest line item in an SEO engagement and the easiest to evaluate loosely. Whether the work met a reasonable standard depends on substance: accuracy, depth, originality and fit with what searchers were looking for. The same standards apply across industries. For law firms in particular, further reading on content quality in legal marketing discusses why content quality shapes how prospective clients find and judge a firm online.
Testing ranking and traffic claims
Agency reports often show rankings for a hand-picked set of keywords. A report can show steady gains while the queries that actually produced leads declined. Reviewing the full query set in analytics and search console data, rather than the report's selection, shows whether reported progress tracked the business outcome the client cared about.
Timing matters too. A decline that begins the week of a documented core algorithm update and hits comparable sites the same way points one direction. A decline that begins the week an agency migrated the site, changed URLs without redirects or published a batch of thin pages points another. Lining up those dates is usually the most persuasive part of the analysis, because it is easy for a judge or jury to follow.
Lead quality deserves its own look. Traffic can rise while enquiries fall if new visitors arrive on informational pages that never convert, or from regions the business does not serve. Conversion records, form submissions and call tracking, where they exist, show whether added visibility produced the kind of visitor the engagement was meant to attract. That distinction often matters more to the dispute than the ranking reports either side relies on.
Finally, competition changes over the life of an engagement. New entrants, aggressive competitor campaigns and shifts in how search results are laid out can all reduce clicks without any fault on either side. A fair analysis accounts for those factors before attributing a decline to the agency or to the client.
Industry norms and what was reasonable
Many disputes turn less on whether the agency did anything and more on whether what it did was reasonable. Industry practice changes, and conduct that was common several years ago may be risky today. Expert analysis places the agency's choices in the context of the guidance search engines published at the time, and of what competent practitioners were doing, rather than judging older work by current standards.
The same applies to the client. Clients sometimes override recommendations, delay approvals or make their own site changes. Those decisions belong on the timeline alongside the agency's work.
Background relevant to vendor disputes
Dan Stratford's view of agency work comes from both sides of the relationship. He founded and ran a digital marketing agency, later operating as C1 Partners, serving clients in legal, insurance, technology, SaaS, home services, education and eCommerce before selling it in 2015. He has also held senior client-side roles, including Chief Marketing Officer and Chief Revenue Officer. His published search engagements include:
International Metaphysical Ministry, Inc. v. Wisdom of the Heart Church — U.S. District Court, Northern District of California (2025). Trademark and digital competition. Testimony refuted allegations of SEO manipulation by demonstrating how Google search and autocomplete algorithms work, showing with data that the observed results were consistent with organic behaviour rather than intentional deception. The matter ended in a dismissal with prejudice following resolution.
