302 Redirect
In one sentence
A temporary redirect, telling the engine the original URL will return.
Analogy Mental model
A sign saying we are renovating, please use the temporary shop. The implication is that the old one comes back.
In practice What you actually do
Correct for A/B tests, maintenance windows and geo routing where the destination differs by country. The original URL stays in the index, which is exactly what you want while a test is running.
Where people get burned Pitfalls
Using a 302 for a permanent move tells the engine to keep the old URL and withhold the transfer, so the new page never inherits what the old one earned. Check the status code, not the visible result.
