It will depend on two things: one, the search phrase the visitor uses and two, the specifics of the relevant algorithm at the time. On the whole, though, the difference isn't too significant, even though studying the language regardless of where the visitor is located isn't exactly the same as learning it from a U.K. address. What's perhaps more important is the truth: are you looking for potential customers on your U.K. doorstep (assuming that's where it is) or doesn't their locale matter? If your need is the former, inclusion of the word "in" would be preferable. Otherwise, leaving it out is probably more advisable. Duncan
I think they are mostly the same and different in a little way. Try to search both keywords and you will see a little difference in a result.
Depending on how competitive the phrase it, the differences could be drastic. I know for a fact that one of my sites keywords, which is competing with around ~11,000,000 sites, even adding an 's' to the end of the phrase throws the results all over the place. For example, 'key word', I come up 5th, 'key words', I'm gone. You really need to find the optimum key phrase and optimise your site for that, and build links using that specific anchor text.
u can google the keywords and you will see the different. searching with ("study in uk") is not the same as (study in uk)
