Map pack visibility depends on a mix of relevance, distance, and prominence, and each of those responds to different levers.
Relevance
A complete, accurately categorized profile with relevant keywords worked naturally into your description helps match you to the right searches.
Distance
You can't move your business, but accurate address data ensures you're being correctly placed relative to the searcher.
Prominence
Review volume and quality, citation consistency, and overall web presence all feed into how prominent your business appears relative to competitors.
Next step: Use the Domain Authority Checker to see how your overall web authority compares with competitors in the map pack.
