Someone on Reddit Described Our Source Index Without Knowing It Exists

A highly-voted comment in an archived r/SEO thread, do expired domains actually still work in 2026, describes a way of finding expired domains that we recognised immediately. It is the method our source hubs run continuously. The person writing it has no idea we exist, which is the part that made it worth reading twice.

We have written both halves up properly, as the reverse hunt and the index test. This is the short version of why we think the method is right, and where we would not follow it.

The method, paraphrased

Work backwards from trust. Look at the links pointing at the sites already ranking in your subject, and pick out the most trusted linkers rather than the highest-scoring ones: associations, non-profit directories, institutions. Crawl those sites yourself and read their outbound links, because the dead ones point at domains nobody renewed. Judge each candidate on whether its own links are numerous and on topic, and on whether the name is a generic word carrying no company name or trademark. Then prove it: register the name, put a small site on it with no outbound links and no redirects, submit it, and see whether it gets indexed inside three to five days.

That is four steps, and the first three are a description of a data pipeline.

Why it matches what we built

We built the directory in that direction because it was the only direction that produced anything worth listing. Starting from a drop list gives you a million names and no reason to care about any of them. Starting from the sites that still link out gives you a much shorter list where every entry arrives with its own evidence attached.

The source index is that list. As of 14 September 2026 it names 106 well-known sites with at least one live listing, across 11,255 listings in 30 top-level domains. Every link was found in our own web crawl rather than claimed by a seller, which is the same standard as crawling the linker yourself. The institutional slices are small, which is what you would expect: 108 listings carry a link from a tracked university and 42 carry one from a tracked government site.

The two facts the comment gets right and most buying advice gets wrong are the ones we would defend hardest. Trust is a property of the linking page, not of a score. And the name matters as much as the profile, because a dead company's name is a trademark problem with a cheap registration fee attached.

The two checks we would add

Neither is exciting and both have saved us from listing domains we would have regretted.

A spam screen on the history, not just the links. A domain can have an excellent set of linkers and a final two years as something else entirely. We screen every listing's archived history for spam, blacklist flags and adult-content history before it goes in, and 9,552 of the 11,255 listings, or 84%, pass the low spam screen. The share that does not pass is the share a link-only method would hand you with a clean bill of health.

Site history read as a timeline. The archived snapshots matter less as a count than as a shape. One consistent subject over years is the signal. The stretch just before expiry, where a legitimate site turns into a link farm, is what disqualifies a candidate that looked good on its links alone.

We also re-check availability against the live DNS root rather than trusting a drop feed, and every listing in the index was re-checked inside the last 30 days. A stale row is worse than no row, because it wastes the one thing this work runs on, which is the reader's attention.

What we are not claiming

The index test is the part of the method we like most and can prove least. The account reports registering about 50 fully dropped domains in a month and roughly 30 of them indexing within days, with links from those lifting rankings and sales. That is one person's reported result. We have not reproduced it, we are not going to quote it as a conversion rate, and a ratio like that says nothing about the specific name in front of you.

Per domain, this is still a gamble. The screening shortens the odds. A fast index tells you Google is treating the name as an ordinary live site, which is the floor and not a ranking promise. Anyone selling you more certainty than that is selling something else.

What the method does do is put the work in the right order. Read the links, read the history, check the name, then spend the registration fee on proving it rather than on hoping. If you would rather start from a list than a crawler, browse the directory and pick the source hub closest to your subject.
