Targeting Local Businesses with Serper and Google Maps: GTM Gold Standard or Missed Opportunity? What If I Could Get You 50% More Coverage?👇

Many owners deliberately stay off Google Maps. Below are key reasons businesses choose not to list:

• Limited recourse on unfair reviews makes owners feel powerless.
• Drive-to-location businesses prefer service area and lose Maps pin.
• Fake reviews and review-bombing can damage reputations overnight.
• Privacy or safety worries deter home-based or sensitive businesses.
• Public phone numbers invite spam calls and scams.
• Crowdsourced edits can change details without owner approval.

Serper.dev is the best there is for reading Google Maps, but it is not perfect either:

• Using only county or city coordinates instead of a fine 14x grid misses listings.
• Maps shows limited results per page and incomplete pagination leaves out additional listings.
• Google ranking factors and frequent algorithm updates can suppress or reshuffle businesses.

✅ We scanned three Bay Area cities at 14x fine grid and compared results with DiscoLike dentist data for businesses with websites, with dead and parked domains removed:

• San Francisco: 182 vs 501
• San Mateo: 51 vs 58
• Palo Alto: 44 vs 47

Average: 92 vs 202

👉 Unexpected? You’re missing half the businesses. Restaurants do slightly better, most others worse. Scan any city and vertical, send me the data, and I’ll return the DiscoLike list to compare.
