Should pages which are almost identical, bar a few minor changes for particular locations, share the same URL? I am not talking of pages in different languages, but pages which have minor differences in spelling, grammar or nouns tailored to particular locations. For example (American-British differences):
spellings such as 'flavour' vs 'flavor'.
nouns such as 'zucchini' vs 'courgette'. Many British persons would not know what a Zucchini is.
One concern is that these differences will be propagated to the search results page. The Zucchini examples seems particularly problematic, as many people would search for 'courgette' instead.
Does using multiple URLs have any adverse impacts on SEO?
