I fully agree, elguiri. Just had to re-do a flashed website in html ... They thought they were really tricky and loaded some html-pages with keywords, not even hidden, and just patching the flash-movie over it. needless to say they weren't ranked anywhere they wanted to be but, of course, they also had the worst bounce-rate I've seen so far. Every user who jumped on the site from serps or adwords (yes, they even spent money instead of figuring out their problem) would see the intro (about 4 seconds), then start on the null-information-here-startpage.
between one and two clicks later (but hey, content-fading, yay) he'd get the information he cam for. Needless to say that hardly anyone ever stayed that long. I was brought in on the subject when they "optimized" their adwords campaign, since "we must attract the wrong people, nobody ever calls or writes to make appointments". explaining why the whole idea is messed up took quite a bit of time.
