Welcome to the Q&A Forum

If it's purely from a user point of view and you don't need Google to crawl the links I have two suggestions: 1 - Do it in JavaScript or some other language that Google can't click, then there is no way Google can see or use the links 2- Alternatively you could always just stick a no-follow on all the navigation links Not sure if either of the above help, kind of confused at your needs to be honest. If you truely build it in the best interest for the users, the number of links shouldnt be an issue. If it's all city links, why not try grouping them into the country, then into city. Craig
