ATRP (Average True Rank Position)

ATRP is a geogrid performance metric that improves on ARP by penalizing non-appearances more heavily than simply assigning position 20. It provides a more accurate picture of how a business actually performs across its geographic service area.

Definition

ATRP treats grid points where the business doesn’t appear as significantly worse than a weak ranking.

Different geogrid tools calculate ATRP slightly differently, but the conceptual intent is consistent: invisibility is worse than ranking #15.

If standard ARP assigns position 20 to non-appearances, ATRP might assign position 30 or apply an exponential penalty. The exact calculation varies by tool, but the result is always the same: ATRP exposes dead zones more clearly than ARP.

Lower is better. And when ATRP is significantly higher than ARP, that gap reveals a specific problem.

Why ATRP Is More Actionable Than ARP

ATRP answers a practical question: Where are we invisible?

Grid points where your business doesn’t appear at all represent the geographic areas where potential customers search and you don’t exist. These are your dead zones.

Fixing dead zones has higher impact than marginal position improvements:

  • Moving from position 12 to position 8 in an area you already rank: small impact
  • Becoming visible in an area where you were invisible: opens entirely new customer pool

ATRP improvement focuses your optimization work on the highest-leverage geographic opportunities.

The ATRP-ARP Gap

When ATRP is much higher than ARP, you have a dead zone problem.

Example:

  • ARP: 4.2
  • ATRP: 7.8
  • Gap: 3.6 points

This gap indicates many grid points where the business doesn’t appear at all. The business might rank well near its address but completely disappear 2 miles out.

Diagnosing the gap:

  • Large gap = proximity-dominated ranking (strong near address, invisible at distance)
  • Small gap = consistent ranking across geography (whether good or poor)

A business with ARP 5.0 and ATRP 5.3 has different challenges than one with ARP 5.0 and ATRP 9.2. Same ARP, completely different problems.

ATRP and Proximity Cliff Analysis

Geogrid data often reveals a “proximity cliff” — the distance from the business address where rankings fall off sharply.

ATRP captures this cliff effect:

  • Businesses with steep proximity cliffs have high ATRP relative to ARP
  • Businesses with gradual ranking decline have ATRP closer to ARP

What causes steep proximity cliffs:

  • Strong local competitors in outlying areas
  • Weak prominence signals (reviews, citations, authority)
  • Category competition in specific zones

Understanding your proximity cliff helps prioritize geographic targeting for optimization.

Optimizing for ATRP Improvement

To improve ATRP, focus on building prominence signals that sustain ranking at distance:

Review signals:

  • Reviews mentioning specific neighborhoods extend geographic relevance
  • Higher review count and rating build prominence that carries further from address

Citation targeting:

  • Citations in directories serving outlying areas
  • Local chamber memberships in target zones
  • Geographic-specific business associations

Local link building:

  • Links from organizations in dead zone areas
  • Local press coverage mentioning service area breadth

Content and schema:

  • Location pages targeting underperforming zones
  • areaServed schema covering full service territory

These prominence signals tell Google your business serves the broader area, not just the immediate vicinity of your address.

ATRP in Campaign Reporting

ATRP trending is a campaign health metric.

Realistic expectations:

  • Month 1-2: Baseline established
  • Month 3-4: ATRP improvement begins (if optimization work is effective)
  • Month 5-6: Significant ATRP reduction possible
  • Month 7+: Continued improvement at slower rate

Reporting format:

ATRP Trend — [Business Name]
Month 1 (baseline): 8.4
Month 2: 8.1 (-0.3)
Month 3: 7.2 (-0.9)
Month 4: 6.4 (-0.8)

Interpretation: Dead zones are filling in. Geographic coverage expanding.

ATRP improvement means your optimization is extending ranking reach beyond the immediate address area.

Claude identifies:

  • Grid quadrants with non-appearances
  • The distance from address where ranking drops
  • Likely causes (proximity competitors, weak signals)
  • Specific actions to improve ATRP
  • ARP: Average Rank Position — simpler metric, less actionable
  • SoLV: Share of Local Voice — top 3 percentage
  • Proximity cliff: Where ranking falls off from address
