Anyway, you shouldn't trust in those numbers in terms of correlation with rankings. Those are kind of "old" metrics that Google does uses, but given the other "hundreds" of signals they use you will be able to see sites without any trust, popularity or whatever metric Moz shows ranking above sites with lots of power... Even more now, when many of those "power" sites may have site-wide, or partial penalties of any kind...

Keri, what do you think about this: http://moz.com/community/q/changing-domains-from-net-to-com-after-7-month-of-traffic-loss

Lisa, use the plugin @Saijo George recommended: http://wordpress.org/plugins/limit-a-post-title-to-x-characters/

It will do the trick automatically for all pages and it doesn't require any programming (PHP or MySQL) skills.

Eugenio,

I don't think there's a way to tell Google what to show. However, if you are building your site in such a way that it has content markup (such as schema, microformats or using the highligh tool in WMT), you are basically telling Google that that is the best way to display the search results.

If you actually prefer to show the meta description (although it is impossible to force Google to do it), you should remove whatever markup you have in your site, then let Google just display what it wants (hopefully your meta description).

PS: the keywords tag isn't used by Google anymore, that's a useless tag you can safely removed. However, Bing said that they still use the keywords meta but it is just one of over 2000 ranking signals they use. So it's basically up to you use it /don't use it (you won't find a big site making use of the keywords meta anymore).

Hope that helped!
