List every domain your practice has owned, including misspellings and the pre-rebrand name. Run a site: search on each. Anything indexed that you don't maintain is a finding. Expired domains are worth checking twice — re-registration by third parties is common and your name may still be attached.
Start with the inventory, because nobody has one
Most firms cannot list their own domains from memory, and that is the finding before any search runs.
Sit down and write out every domain the practice has ever controlled:
- The current one.
- The one before the rebrand.
- The one from the previous partnership or predecessor firm.
- Common misspellings someone bought defensively.
- The
.netand.orgversions bought at the same time as the.com. - Anything bought for a campaign, a single service line, or a location.
- Anything a former marketing vendor registered on your behalf.
That last category is the one that produces surprises. Domains registered by an agency, in the agency's account, under the agency's billing, are not really yours — and when the relationship ended, nobody transferred them.
Cross-check the list against your registrar accounts, your accounting records for annual renewals, and your email archive for expiry notices.
The searches
For each domain on the list:
site:olddomain.com — shows pages Google has indexed on that domain. Anything returned is live and findable.
Type the domain into a browser. Does it resolve? Redirect to you? Show a parked page? Show someone else's content?
Search your firm name in quotes — "Your Firm Name" — and read past the first page. Old domains, directory profiles, and predecessor listings surface here.
Check the Wayback Machine for anything you're unsure about. It shows what a domain used to serve and roughly when it changed hands.
The four outcomes
Redirecting cleanly to your current site. The good case. Worth confirming it's a single 301 hop rather than a chain, and that it points at the right page rather than dumping everything on the homepage.
Resolving but showing old content. Two versions of your firm are live and indexed. Google is choosing between them, and you may be competing with yourself using content you forgot existed.
Parked or for sale. No longer yours, or expired and picked up by a registrar. Any links pointing at it are wasted, but nothing worse.
Serving someone else's content under a name associated with you. This is the one worth acting on quickly. Expired domains with existing inbound links get re-registered deliberately, and what appears on them afterwards is outside your control. We have seen a lapsed domain re-registered and filled with content that had nothing to do with the client's profession — still ranking, still carrying their name.
On the site: operator
Worth stating plainly, since this check leans on it: site: is a rough indicator, not an index dump. Google has been consistent for years that it isn't a diagnostic tool and doesn't return a complete or precise listing. Results and counts vary between runs.
That's fine for what you're doing here. You're asking "is anything at all indexed on this domain," and one result answers that. Don't read the count as a number that means anything.
What you can and can't conclude
Pending — The inventory is something you can genuinely build, and it's the valuable part. What you can't determine from outside is whether these properties are actively draining authority or simply sitting there inert. That means tracing redirect chains hop by hop, checking what links point at each domain and whether those links still pass anything, and comparing indexation over time.
Unconfirmed — Whether a domain you no longer control is damaging you. A re-registered domain serving unrelated content under your name is clearly undesirable, but the mechanism and scale of harm vary a great deal, and anyone quoting you a figure is guessing.
One thing worth doing today
Set a calendar reminder for every domain you still own, thirty days before renewal, in a place that isn't one person's inbox. Most of the bad outcomes in this post begin with a renewal notice going to an address nobody reads any more.
