Richard's website has fallen dramatically on Google's search results, and he's wondering why. Leo says that Google is always tweaking their search algorithm. In order to get a high Google ranking, he has to be linked by other pages that are higher on the list. That's what gives pages what Leo calls "Google Juice."
Leo recommends checking out the Google Webmaster Tools. But the bottom line is, the better his content, the higher his rank. And don't buy into alleged SEO companies that promise to get higher rankings. That's just snake oil. If he tries to trick Google by gaming the system, they could de-list him. So he should go about it the right way.
