Without knowing the city/niche that you are going after, here are some basic tips.
1. Make sure your listing is complete. Add a video/picture. Something relevant to your business. Name the picture/video with keywords that have to do with your business/niche.
2. Reviews are worth a lot. You need to have reviews to beat the competition. Do your research and find out how many reviews you think you need. Go from there.
3. Citations (backlinks) are also important. Copy your competition if you must.
Hope that helps. Ask, if you have any more questions.
