Welcome to the Q&A Forum

Hello Sam. That doesn't sound like panda. If it was panda, you wouldn't be on page 1 for keywords, unless your keyword is the complete title and you are the only one with it. More likely is that your competitors have moved up and maybe some of the sites you dot links from have been destroyed or maybe they dropped their links that point to you, or maybe they made them nofollow. Dropping just a couple of positions would be a wonderful problem to have. If you haven't already done so, I suggest you work through the training, so you understand more, then use the tools in the "Research Tools" menu item at the top of the page.
