If you build it, they will come.
Seriously google hits this site a lot when it comes down to yorkie questions. To choose a recent thread about the poor puppy (glad it's doing better!) that had Parvo is already ranked 6th with google for yorkie+parvo. I will let people know about this site that love yorkies but it really is the search engines that will be your friend.
Like I said you built it and they are coming. I guarantee lots of people come here for information that don't register. How many hits a day does the site get? That would be a good indicator.
*EDIT* Lmao, Sheila+yorkie is #1 with google. My baby's a star
Proof enough that the google bots crawl this site pretty regulaly.
