I bought a domain that had first been registered in 2000. On paper, that history looked like an asset. Then I launched my new site and the server logs started filling with requests for pages I had never created.
More than 1,000 requests per day were hitting URLs that did not exist in the new project. In analytics, this showed up as a large spike in direct traffic with almost no engagement. At the same time, Yandex Webmaster accumulated more than 900 errors overnight as its crawler revisited old paths and received 404 Not Found.
My first explanation was simple: old bots were hitting dead URLs, Yandex was seeing that activity, and therefore Yandex kept crawling them. That is what the sequence looked like from my side. It is also stronger than what my data could actually prove.
What I could actually confirm
There were three separate observations. First, the server was receiving a large volume of requests for URLs left over from the domain's previous life. Second, those requests were not translating into meaningful user engagement. Third, Yandex's crawler was also requesting old paths, and its Webmaster dashboard reported more than 900 errors in a single night.
Those facts mattered operationally. They created noisy logs, unnecessary requests and a search-console problem I had to clean up. But they did not prove that third-party bots caused Yandex to crawl those URLs, or that the errors directly hurt rankings or organic traffic. Crawling is not indexing, indexing is not ranking, and an error report is not evidence of a ranking penalty.
The part I had oversimplified: 404 vs. 410
I originally thought about the difference this way: a 404 means “maybe the page is only missing for now,” while a 410 means “it is permanently gone.” That is a useful intuition, but it is not technically precise.
404 Not Found means the server cannot provide a current representation of the requested resource; the status itself does not say whether that situation is temporary or permanent. 410 Gone is more specific: it is appropriate when the server knows that the resource is no longer available and the condition is expected to be permanent.
That distinction also matters for SEO claims. Search engines can remove URLs that return either 404 or 410. So I no longer describe 410 as a magic “stronger SEO status” or say that 404 is inherently wrong for deleted pages.
Why targeted 410 responses still made sense for my case
The old paths I was dealing with were not temporary failures. They belonged to content from the domain's previous history and had no place in the new site. I knew those specific URLs were gone permanently. That made 410 Gone a semantically accurate response.
I therefore configured targeted 410 responses for the known legacy paths instead of treating every unknown URL the same way. After that change, the legacy crawl and reporting noise subsided and the SEO situation became much cleaner.
I am careful about the conclusion, though. What I can say is that the cleanup followed the targeted 410 change and that 410 correctly expressed the state of those URLs. I cannot prove that 410 alone made every bot stop. Arbitrary third-party bots can ignore the meaning of an HTTP status and keep requesting the same path forever.
The decision rule I use now
The useful question is not “Is 410 better than 404?” It is “What happened to this URL?”
- There is a clear replacement: use a permanent redirect such as
301to the genuinely equivalent new URL. - The old resource is known to be permanently removed and has no replacement:
410 Goneis a precise choice. - The URL is simply unknown, mistyped or never existed: a normal
404 Not Foundis appropriate.
What I would avoid is redirecting every dead URL to the home page just to get rid of errors. That hides the real state of the resource and can create a worse experience for both users and crawlers.
How I would audit an aged domain before launch
If I reuse an old domain again, I would treat its URL history as part of the migration, even if I am not migrating the old website itself.
- Inspect the old footprint. Look for historical URLs and obvious legacy sections before launch.
- Watch access logs from day one. Repeated requests to paths you never created are useful evidence that the domain still has external memory.
- Separate humans, search crawlers and random bots. A direct-traffic spike and a crawler error report are different signals and should not be merged into one explanation.
- Classify recurring dead URLs. Decide whether each important pattern deserves a 301, 404 or 410.
- Monitor the result. Check request frequency, crawler reports and indexing separately instead of treating “SEO health” as one metric.
This is a small amount of work compared with discovering the problem only after the logs and webmaster tools are already noisy.
What 410 does not solve
A 410 response is an HTTP statement about a resource. It is not a firewall rule, a rate limiter or a bot-blocking mechanism. If a scraper keeps sending requests after receiving 410, the server still has to receive and answer them. If the real problem is abusive request volume, that is an infrastructure problem and should be handled separately.
It is also not an SEO boost. Returning the correct status helps a crawler understand what happened to a URL; it does not make the new site rank better by itself.
The lesson I kept
The surprising part of this project was not that an old domain had old URLs. It was how quickly that invisible history became visible again after launch: more than 1,000 requests a day to pages I did not have, almost no engagement, and more than 900 Yandex Webmaster errors overnight.
An aged domain is not a blank namespace. Old links, crawlers, scripts and bots can remember paths long after the original content is gone. My current rule is simple: audit that history, return the status that matches reality, and keep operational bot traffic separate from search-engine conclusions.
History can be an asset. It is also state you inherit.
