Search Engine Optimisation all boils down to, in the end, "make websites that humans want to find, and search engines will tend over time to detect sites like yours". The SEO best-practices change all the time, but the ones which stick around tend also to be general usability best-practices.
There doesn't seem to be a similar rule for elections, ie "make candidates that humans want to govern them, and people will tend over time to elect candidates like yours".
Perhaps this is because nobody has actually tried such a strategy, but I expect it has more to do with the ideas that:
1. having lots of choices and few choosers (the choosers being chosen by the masses) tends to work-out better than having lots of choosers (the masses) and few choices
2. letting people benefit from more than one "winner" tends to work-out better than picking the top choice and throwing out everything else.
