For WordPress.com hosted blogs, they ask you if you want your blog to be search able from the beginning.
If you missed it during signup, no fear.
- Login to your hosted WordPress account.
- Click on the “Settings” tab
- Click on the “Privacy” link.
However, if you have WordPress on your own webhosting, you can also follow the same steps above.
Thanks to Stephanie Fierman of Stephanie Fierman Marketing Daily for bringing this to my attention.
