I was trying to rank for a local keyword on the map but none of my techniques are working.

My website ranks for the search result almost 1st position, but for map? Its a real pain. It doesn't even showing my listing for first 10 positions.

My website is about classroom training. We train students on Python, Machine Learning etc., I want to say that my map is six months old.

Techniques I used.

1. Reviews: As we train students we ask them to write reviews on Google map listing. I have 146 good reviews and they are all about various courses like python, java, c, Data Science etc., But my listing doesn't show either of these keywords.

2. Keyword in the name: We tried to put keyword in the name itself. It used to rank for Data science training. But that long name is bothering my client so I have to change that to the original name. But other listings are ranking only with their original name and keywords found.

3. Embedded Map: I Embedded the map of my business listing in every page on my website possible to find us. And that doesn't do a thing with my local rankings.

What do you suggest more to do to rank my business listing for a term.
