If, for some unfathomable reason, you put a meta tag refresh on every page of your site, you may want to consider not putting it on any page with a form on it. Especially a long complicated form. 30 minutes may seem like a long time to fill out a form, but sometimes people answer the phone or get up for a coffee break. Perhaps the refresh may even make them decide that they have better things to do than pursuing a transaction with your lame site. (Like blog about how lame you are.)
Faux pas.
I’l ne faux pas faire ca!
What about a Sudoku game on the site of a newspaper (swedish) that refreshes? Don’t try a too high level!
It’s better to not use the meta refresh if you like your listing at Google
Some search engines could see this as a redirect or doorway pages, by the way on regular pages you don’t need are fresh
@Paul: Faux pas: yes!
But: Il ne faut pas faire ça!
Just to completely fix it
