This is great for anyone that has an outdated ODP listing – who doesn’t these days – or simply prefers not to have it displayed for their site.
As MSN points out, just don’t expect an immediate fix:
A word of caution: Putting either tag in your pages will not make your search results descriptions change immediately â€“ they will change once our crawler has re-crawled the page. Usually that takes about 1 day -4 weeks for us to re-crawl you (ok, that sounds odd, but we hope you know what we mean).
Nice work guys. Let’s hope Google goes along with the new tag.
