So I'm going to try to rank for a local keyword (profession + city) and the search volume is very low. It's around 500/month. Now, I understand that ranking a site for keywords locally is much easier than ranking globally. The top sites (page 1) for my keyword have little to no on-page optimization and hardly any backlinks. My goal is to rank this site in the top three positions AND maintain the rankings. My question is, what sort of backlinking strategy should I implement? Any help would be greatly appreciated. I'm rather new to SEO.
