Here’s an idea worth revisiting in arbitrage discussions: people still click old, trusted links from major publications. Buyers acquire a dropped domain for its link equity, set up a blind 301 to their project, and think they’ve captured everything. In reality, they’ve captured only half; the other half—real referral traffic—goes nowhere. And since March 2024, this kind of blind redirect to an irrelevant page has become risky in its own right. Below, we’ll look at how to capture both link equity and visitors without violating search engine rules or the law.
What you’re really buying along with a dropped domain
A purchased domain with a history has two distinct assets, and they’re constantly confused.
The first asset is accumulated link equity. It’s about algorithms: PageRank, trust, link age. The second asset is referral traffic from those links. It’s about people: someone reads a five-year-old article on an industry website, sees a link, and clicks it. This visitor is already prequalified: they’re interested in the topic, they’ve read as far as the link, and they’re ready to click through. Acquiring a visitor like this through paid channels costs money—sometimes a lot.
A blind 301 in the registrar’s dashboard tries to capture only the first asset and ruins the second. Someone clicks a link in an article about, say, medical equipment and ends up on a payday loan page. They close the tab in a second. You might capture some link equity, but you’ve lost a real visitor and sent the search engine a signal that the redirect leads somewhere it shouldn’t.
Why a blind redirect now works against you
In March 2024, Google introduced a dedicated spam policy against expired domain abuse. It applies to buying a domain with a history to use its past reputation to push unrelated content into search results. Google’s own examples include affiliate content on a former government website, medical product sales on a medical charity’s domain, and a casino on the site of a closed school. It’s exactly the scheme pitched in chats as a “powerful dropped domain for any offer.”
The second mechanism is less obvious, but it affects the very link equity this is all supposed to be about. Google’s modern handling of 301 depends on topical relevance. A redirect from a page on one topic to a page on a completely different topic is increasingly treated as a soft 404: link equity isn’t passed on; it’s wiped out. So a blind redirect from an irrelevant dropped domain to a shady project could result in a spam-policy penalty—or, at best, pass on nothing.
An important caveat: using an old domain for a new project is perfectly legal and legitimate in itself. Google explicitly says you can use a domain with a history for a new, original website made for people. The problem isn’t the dropped domain, but changing the topic and counting on its past trust to prop up low-quality content.
How to capture link equity by the book
The basic rule follows from how search engines evaluate 301: the closer the new page’s topic is to the old page’s, the more historical signal carries over. So you need to work with specific pages that valuable links point to, not just the domain root.
- Export the dropped domain’s backlinks and check exactly which URLs they point to and what topics they cover. The value isn’t in the domain as a whole, but in the handful of pages linked to by publications.
- Create a relevant page on your project for each of these URLs, covering the same topic as the dropped domain page and the linking article. Then 301 falls within the same topical neighborhood, and the link equity carries over.
- Don’t funnel all the old URLs into one redirect to the homepage. That’s the classic way to turn a transfer of link equity into a soft 404.
- Keep the redirects in place for a long time. Google advises leaving them up for at least a year: signals aren’t recognized instantly.
- Avoid redirect chains. Every extra hop loses some link equity, so the redirect should lead to the final URL in one step.
A slower but more sustainable approach is not to redirect the domain, but to build a standalone topical website on it that continues the original subject, then link to your project from there or incorporate it into the site structure. It takes more time, but doesn’t conflict with the spam policy and doesn’t depend on how the search engine assesses the redirect’s relevance.
How to capture real traffic instead of wasting it
Now for the other half—the people who click old links. The goal isn’t to “intercept and sell,” but to avoid losing visitors to a blank screen and give them what they clicked for.
If you’ve restored a relevant page for the old URL, you’re halfway there: visitors land on content related to their interests rather than an unrelated offer. From there, it’s standard traffic management.
- Tag visits from restored URLs with tracking parameters (UTMs or separate pages) so you can see in your analytics how many people actually arrive through historical links and which referring sites they come from. Often, two or three links drive almost all the click traffic, while the rest are dead.
- Build landing pages for this traffic around what readers expect from the referring article, not a hard sell for your offer. If someone arrives from an article about choosing equipment, give them an analysis and comparison, and make the sale the next step.
- Entry points from historical links are a good place to build an audience transparently: offer a subscription or useful content in exchange for contact details, and use a retargeting pixel with an appropriate consent banner. The difference from a “cookie bomb” isn’t just cosmetic: visitors can see they’ve arrived at your site and choose to stay.
Retargeting that won’t get you banned or fined
The temptation to build data collection into the redirect itself is understandable, but that’s exactly what turns the scheme from gray to illegal. Platforms and the law are aligned on this.
Facebook Conversions API and Google Customer Match require a lawful basis for processing data and, for EEA users, explicit consent. Since March 2024, Google has required both consent fields to be set to GRANTED when uploading an audience to Customer Match; otherwise, the data won’t be processed. You can upload only first-party data collected lawfully. In Meta’s case, a German court made the requirement even stricter in 2026: without consent, CAPI cannot run at all, even in a limited form. Hashing doesn’t help: hashed identifiers are still personal data.
The practical takeaway for traffic arbitrageurs: build your retargeting audience at your own entry point, with a consent banner and clear information about how it works. The list will grow more slowly, but platform moderation won’t wipe it out, and you won’t face a regulator’s complaint. Hidden collection through a service worker can grow your list quickly, but that growth can be wiped out at any time along with your ad account.
What to do with your next dropped domain
A short checklist for capturing both assets without putting your project at risk:
- Before buying, don’t just look at the number of links. Check which pages they point to, what topics they cover, and whether the referring sites are still active. A dead referring site brings neither link equity nor traffic.
- Restore relevant pages for valuable URLs instead of funneling everything into a redirect to the homepage.
- Keep the redirect topically relevant. Otherwise, link equity will be wiped out as if by a soft 404, and the domain risks falling foul of the spam policy.
- Track historical traffic and build landing pages around what visitors are looking for, rather than immediately pushing your offer.
- Build your retargeting audience with consent on your own site, not by secretly intercepting visitors through a redirect.
The idea from the chats is only half right: valuable traffic from old links really is being wasted. But it’s more profitable to capture it by the book—that way, you get both link equity and visitors, and don’t lose everything when an algorithm or a moderator decides the redirect leads somewhere it shouldn’t.
