I am the owner of escortatorino.com , a site that operates in the escort sector in the city of Turin, in Italy. My experience started more than 4 years ago and I still haven't managed to get the top positions for what concerns the reference city, due to a high competitiveness. The industry is very tough and getting quality backlinks is extremely difficult. I have found the answers given in this forum interesting and useful and I agree with those who say that domain authority is perhaps the most determining factor.
