Search Volume data storage
We store Search Volume data in a common database without linking it to a particular user. For example, a user A signed up on 2013/03/03 and checked Search Volume on the same day. Another user B signed up on 2013/02/14 and added the same keywords to the project. The user B will automatically see Search Volume data pulled from the common database. But this data is out‑of‑date.
We do recommend to check keyword Search Volume monthly to keep your data up‑to‑date.
