Obviously looking at top landing pages and keywords is a big part of it, but the Analytics data is really the most useful when you have have another set of data to cross reference it with, e.g. if you know that you're ranking at number 11 for a keyword that gets 1,000,000 searches a month then that keyword is probably worth targeting. But you'd only get one of those 3 bits of information from GA, the rest you'd have to get elsewhere
Does google analytics tell you your ranking for a particular key word? If not is there any tool out there which does this?
Google Webmaster Tools does (well, for Google search anyway).
Thanks. Any other good tools for SEO?
