What Would Seth Godin Do lets you greet first-time visitors with a tailored welcome message — like an invitation to subscribe to your RSS feed — and show a different (or no) message to people who have already been to your site before.

The plugin stores a small cookie that counts how many times a visitor has been to your site. While the count is at or below the “# of Repetitions” threshold you configure, the new visitor message is shown. Once the visitor exceeds that threshold, the return visitor message appears instead.

Inspired by Seth Godin’s 2006 blog post: …in the middle, Starting.

Features:

Separate, fully customisable messages for new and returning visitors.
Configurable repetition threshold — choose how many visits count as “new”.
Choose whether messages appear before or after post content, or only where you place the <?php wwsgd_the_message(); ?> template tag.
Option to show or hide messages on Pages (vs. Posts only).
Exclude specific post or page IDs from showing any message.
No external dependencies; lightweight vanilla JavaScript.
