Cloaking

Evil CMO says: “Show Google one page and show customers another. Everyone gets what they want.”

What it actually is

Serving search engines a different page from the one real visitors see.

Why it blows up

It’s one of the few things Google will remove a whole site for, and a manual penalty takes months to undo.

The white-hat version

Make the page people see good enough that you’d happily show it to Google.

The honest way, explained properly: SEO, dumbed down.
