Search engines and flash

I prefer to use flash. I always place my swfs in an html page so the viewer can use the back buttons. I put keywords in the head of each html. But, I have heard that search engines use content in the html body much more than key words. I thought of putting a content paragraph in the html page behind the swf so it is hidden to the viewer, but was told that search engines will disqualify you for hidden html. Is there a way to get my flash sites recognised by search engines? thanks
