what is the name for this part of Google SERP?
How to improve the position in that sub-list? As you can see there are 7 seven results (from letter A to G). My company is on the letter J now, I have checked it just pressing "Ver resultados de empresa reformas guadalajara en un mapa".
So my questions are:
1. what is the name related to that sublist (just to look for information in internet about it by myself)?
2. how to improve the ranking there?
