We will ask you to give us 5 keywords, but in local results, if you target a term like dentist London, you will often rank for its variation like dentist in London, London UK Dentist and the like. As long as you have selected the appropriate categories in your Google Places listing, so as to point Google in the right direction, we tend to see people rank for a whole bunch of keywords. Yes, we have had success with tricky terms like those suggested. However, I wouldn’t recommend ONLY purchasing a Loganix package, and expecting to rank for these terms. Competitive terms like these will require a well optimized site, additional backlinking, and more. Consider the value in ranking for these terms.
