Survivorship Bias in SEO Case Studies
Learning from the one site that worked while ignoring the hundreds of identical attempts that were deindexed, penalized, or simply never ranked.
Analogy Mental model
You see the lottery winner holding the check. You don't see the thousands of people at the counter every day who tore up their tickets on the way home.
In practice What you actually do
When someone presents ten thousand AI articles driving half a million visits in three months, ask what the case study skips: how many sites did this take, and did the others die? Is the site still indexed? Was the traffic ever monetized at a real rate? What did the domain already have before the experiment began?
Where people get burned Pitfalls
Conference talks and social threads show the surviving project because that is the one with a story. The base rate — how many attempts failed — is the number that decides whether the method is repeatable, and it is almost never disclosed.
