The Redirect module is a powerful tool for mass-page building and launch-jacking. It enables you to create a snippet that, when a user lands on a blog, is instantly taken to a money-site (for example).
Now, with Delay options, you can let Google index your blogs, and time the activation for the redirects. You could use this to rank blog-posts, then, in 2 weeks time, start redirecting real traffic to your money-site, affiliate product, etc.
To use the module, click on the module:
Then, input a URL to redirect to and (optionally) a delay for activation:
Click "OK" to save, and regenerate pages as needed.
Just like that, any user that lands on the page will be taken to the Redirect Target you've set – no coding required.
