i use filters/tags on my webapp to sort articles dynamically. now these filteres do not really match microformat.org's idea of rel="tag" (no url, not a tag, i don't know), but i don't see any other way to avoid google seeing it as keyword stuffing.
is there a better way so highlight these "tags" or would you encourage me to use rel="tag".
see it yourself: http://www.rewow.de/eiweisspulver/
thank you very much!
Clicking one of the "tags" changes the content of the page using JavaScript.
Your JavaScript should be unobtrusive and progressive.
They should be links with URLs and if the JavaScript fails, then you can generate the same content on the server. (You can use pushState to make the address bar match the target page when you successfully transform the current one into it with JS).
That way they match microformat.org's idea of rel="tag", and your site is more reliable and search engine friendly.
