Buying a domain usually feels like a fresh start. You check the spelling, the TLD, and the price. But we often forget one crucial factor: history.
I learned that lesson the hard way. I picked up a domain that had originally been registered in 2000. It felt like a great find—right up until the server logs started filling up.
Day One: A Bot Invasion
Almost immediately after launch, my traffic logs spiked. I wasn't getting real users. I was getting hammered by more than 1,000 requests per day for URLs that didn't even exist on my new site.
It turned out to be an army of bots aggressively probing for pages that had existed years ago. They were looking for the domain's former life, creating a huge spike in direct traffic with almost no engagement.
Why This Hurts SEO
The problem wasn't just server load. The real issue was how search engines interpreted that noise.
Because bots kept hammering those dead URLs, Yandex treated them as if they might still matter. Its crawler started aggressively revisiting those ghost paths, only to hit walls of 404 (Not Found) errors. My Webmaster Tools dashboard lit up with more than 900 errors overnight.
The Solution: 404 vs. 410
Many developers rely on a standard 404 for missing pages. In this case, that wasn't enough. A 404 tells a search engine, in effect, “I can't find this right now. Maybe check again later.”
To stop the damage, I had to switch to Status 410 (Gone).
A 410 response is final. It tells the crawler: “This page is gone for good. Do not keep it in the index.”
Implementing targeted 410 responses for those legacy paths was the only thing that stopped the noise and cleaned up my SEO health. If you're buying an aged domain, don't just launch the new site—audit the old footprint too, and have a 410 plan ready from day one.
