A client has the requirement to provide translation options on their website, most likely using an automated solution like Google Translate. A colleague and I have been discussing the best way to present that control and are both of the opinion that it makes sense for it to appear at the top of the page (so that it is immediately easy to find when arriving on the page). The client has suggested that it should appear in the footer.
Based on a quick look around the web, translation options do indeed frequently appear in the footer, so there is an argument that we should follow that convention.
EDITED to include some examples of sites with language options in the footer:
Why are language options frequently presented in the footer? Is is purely to save valuable space above the fold? Ultimately, my question is, where is the best place for this control to appear from a usability perspective?
