Vetting Expired Domains in iGaming SEO

Picture a domain that spent years collecting backlinks as a Swedish restaurant. It expires. Someone buys it, slaps casino content on top, and it ranks. Not as a curiosity, not as a brief fluke before Google's algorithms notice the mismatch — it ranks, and it keeps ranking.

That scenario is the starting point for a recent episode of The Squared Table, hosted by Victor Julio Coupé for Kensho Media, featuring SEO consultant Craig Campbell. The conversation is framed as practical guidance on evaluating expired domains before purchase. But threading through the tactics is something more structurally interesting: an industry where the rules everyone was taught appear to hold everywhere except here.

The topical relevance problem

The foundational principle in modern SEO is topical authority — the idea that Google rewards sites that demonstrate deep, consistent expertise in a specific subject area. A restaurant site should not be able to pivot to ranking for casino keywords, because nothing in its history signals gambling expertise. The logic is clean, the theory is well-supported, and according to Campbell, it just doesn't seem to apply in iGaming the way it does elsewhere.

"It goes against what I think should work from a common sense point of view," Campbell says on the show. "But if it works, then you've got to double down on strategies that are working for the here and now."

That's a practitioner's answer, not a theorist's. Campbell isn't claiming to understand why Google's algorithm behaves differently in iGaming — he openly says he can't explain it. What he is saying is that the empirical reality on the ground contradicts the official account, and that ignoring empirical reality because it contradicts your model is how you lose to competitors who are less attached to models.

The honest tension here is worth sitting with. Google's published guidance, the SEO academic consensus, and the stated logic of how the algorithm is supposed to work all point one direction. Observed outcomes in iGaming SERP rankings point another. Campbell's position — embrace what works until it stops working — is commercially rational but leaves open the question of whether the discrepancy is a permanent quirk of the vertical or a correction that hasn't landed yet.

Two very different kinds of operators

One of the more clarifying parts of the conversation is Campbell's breakdown of who is actually using expired domain strategies in iGaming, because it turns out "iGaming operators" covers a pretty wide range of risk tolerance and business models.

On one end: offshore operators in markets where online gambling is illegal or unregulated. These operators are not primarily worried about Google; they're worried about government enforcement. Their window before a site gets taken down can be measured in weeks, not years. For them, the calculation is straightforward — spend a thousand dollars on an expired domain, make twenty thousand before the site disappears, repeat. Campbell describes it as "churn and burn," a production line running ten sites simultaneously and cycling through them as each gets shut down.

On the other end: licensed, longer-term brands with reputational skin in the game. These operators care about footprints, about not having their main brand associated with shortcuts that could attract a Google penalty. Campbell's advice for this cohort is to create structural distance — run the riskier tactics through sub-brands, affiliate-style entities, or separate properties that aren't traceable back to the flagship. Whether that structural separation is fully effective at shielding the main brand is a separate question, and one Campbell doesn't claim to answer definitively.

The practical upshot is that "should I use expired domains?" isn't really the right question. The right question is which category you're in, because the answer and the acceptable risk profile differ substantially.

What you should actually check

The more immediately actionable part of the conversation covers due diligence — what to look at before purchasing an expired domain, given that domain marketplaces are not doing this work for you.

Campbell's bluntest point concerns Domain Rating, the metric from Ahrefs that most buyers use as a quick proxy for authority. The problem with DR as a purchase signal is layered.

First, it can be inflated artificially. Someone wanting to sell a domain at a premium can manipulate the DR number through redirect schemes, making the asset look stronger than it is. If you buy based on that number, you're buying something that won't perform.

Second — and this is the more subtle issue — DR can look healthy on a domain that's already been spent. If a previous owner redirected the domain to their own casino property and captured whatever link equity was there, the DR figure in Ahrefs may still reflect the old backlink profile. It won't reflect that the value has already been transferred. "Once someone else has done the redirect and sucked all the power out of it, Google can't just keep giving power and power," Campbell explains. "If someone's had their dirty hands on it, I don't want it."

The Wayback Machine check is the manual step that catches this: look at the domain's history, see whether another iGaming operator held it, and see whether a redirect was used. It's not a perfect signal — Campbell acknowledges he can't say definitively what Google does with previously redirected domains — but it's directional intelligence that no marketplace tool will surface for you.

Third: time. A domain that went dark in 2021 and has been sitting idle since is, in Campbell's view, likely already reset by Google regardless of what the Ahrefs DR still says. The authority shown in third-party tools is a record of historical backlinks; it says nothing about whether Google is still weighting those links for a site that has been dormant for years. Campbell's rough threshold is a year — domains idle longer than that are increasingly likely to have been quietly zeroed out by Google even while the tooling still shows a strong number.

The three-part check, then: Is the DR inflated artificially? Has it already been used by a previous operator? How long has it been inactive? None of this requires expensive software. The Wayback Machine is free. The gap is attention, not access.

What natural looks like, and what it actually costs

The conversation also covers what a natural-looking backlink profile means in practice, since "natural" is another term that gets deployed frequently without much operational definition. Campbell's description is simple: variety. Guest posts, podcast appearances, PR coverage, redirects, canonical signals — the combination of sources that would plausibly accumulate for a legitimate site operating in the real world. No single link type should dominate. A profile that's entirely guest posts, or entirely blog comments, reads as constructed. A profile that mixes editorial mentions, podcast links, and topical placements reads as organic.

The closing observation is probably the most useful reality check in the episode. Campbell's point to operators running modest link-building budgets is that their competitors aren't operating in the same cost bracket. The players ranking above them are spending meaningfully on expired domains, aged domain acquisitions, canonical manipulation, and aggregated asset strategies — not two thousand dollars a month on a backlink package. The budget asymmetry is its own form of competitive intelligence.

That doesn't mean outspending the competition is always possible or advisable. But it does mean that confusion about why your clean, budget-appropriate link-building program isn't moving the needle might have a simpler explanation than algorithm changes or content quality. The question isn't whether you're doing it right. It's whether you understand what "doing it right" actually costs in this particular market.
