# Customer Content Screen Hooks
https://dev.wisecp.com/es/client-content-screen-hooks
The twenty-seven placement points of the home page, content, the knowledge base and the sign-in forms.
## Overview
The placement points on the pages open to visitors live here: the home page, content and the blog, contact, the knowledge base and the sign-in forms.
Most of these pages are **open to everyone**. A script you place here is run by anyone not signed in, and anything depending on a session comes out empty.

## Pitfalls
> **These pages are open to everyone**
>
> Code you place on the sign-in, sign-up and content pages is run by anyone, **identified or not**. Keep internal details, keys and anything meant only for a customer out of them.
> **On the invitation page the other party may have no account**
>
> The sub-user invitation page can open for somebody with **no record at all** in the system. Output depending on a session or an existing customer record comes out empty there.
