1. Does anyone know if an auto-redirector via meta tag is a negative for the SE ranking? Like if your defualt page for that domain is optimized for SE but redirected to the "real page" imediately. Would this affect SE ranking? This is bad right?
2. Uni-code "stealth" seems a little pointless. Is anyone actually doing that? Firstly it seems like it could easily be changed back to ASCI. Second I'm guessing theres no point in using it for most tags cuz it shows up in the browser and can be copied there as ASCI anyway right?. Also, how do we know SE's will not choke on it? Might be usefull for META tag or other tags that don't display in the browser. I guess if they are too dumb to convert it back to ASCI it could still be stolen and used as Uni-code but they would not know what it said so maybe that is a deterrent?
The meta refresh was used (and abused!) a good deal as an SEO technique a few years ago, and the SEs began to penalize for it. AFAIK, quick refreshes are still a bad idea, but I've never used them. I'm confident that a five second (or longer) delay will not cause SE problems.

Yep. Anyone sharp enough to want to look at the metatags in your source can probably convert unicode with little effort.
