Google search results for a particular query was appearing in top 10 results but now the page appears but  only after clicking on the " omitted results by google." My website lists different businesses in a particular locality and sometimes results for different localities are same because we show results from nearby area if number of businesses in that locality (search by users) are less then 15. Will this be considered as "duplicate content"? If yes then what steps can be taken to resolve this issue?
