Thanks for that - it helps a lot!
Do you have any opinions on articles or posting articles to directories?
Again, to me it would seem that a more relevant directory (i.e. a finance one for finance related stuff) is more appropriate is your site is in that niche. You would'nt post an article on dating in one of those niches I think!
Google presumably categorises all of this in a very clever way, I presume the lesson is to stay as 'natural' as possible? E.g. an article on a Kenyan site about a service only available for UK users will get picked up by their algo?
So, how does one control that up front? Is that even possible?
