Welcome to the Q&A Forum

I don't believe that tag causes an auto-refresh. Rather, it is used in combination with an auto-refresh to make sure that nothing is cached in the user's browser, which ensures that the entire page updated during the refresh. If I recall correctly, sending "no-cache" info in the http header is a better practice that using a meta tag. To quote from http://www.mnot.net/cache_docs/#META: "Meta tags are easy to use, but aren’t very effective. That’s because they’re only honored by a few browser caches, not proxy caches (which almost never read the HTML in the document). While it may be tempting to put a Pragma: no-cache meta tag into a Web page, it won’t necessarily cause it to be kept fresh." I couldn't say whether this would affect your page in terms of SEO, but I also don't think there's a reason to use the pragma tag anymore, so in my opinion, it's moot.

Hi Todd, The metrics you're seeing are from February. OSE is usually updated monthly, but we had technical problems and it's been seven weeks since the last update. There's a new update due on April 27th, and you should see some changes then.
