How AI Search Is Recommending Transportation Services: Monthly Trends

Executive Summary

Sherpa Auto Transport remains the category's coverage leader in September 2026, holding the position across the full three-month tracking window. Its valid recommendation coverage stands at 73.8%, essentially flat against the July baseline of 74.5% (down 0.7 points) and up 2.6 points from August's 71.2% — both movements within the benchmark's normal month-to-month range. Sherpa's lead over second-place AmeriFreight is 8.1 points this month.

The one brand that moved outside its normal range this month is Nexus Auto Transport. Its valid recommendation coverage fell from 34.5% in July to 26.2% in September, a decline of 8.3 points large enough to register as significant against the baseline, and it extends a two-month downward streak (34.5% in July, 29.9% in August, 26.2% in September).

Elsewhere, the category was stable. AmeriFreight posted the largest single-month gain, up 3.0 points to 65.7% from August's 62.7%, though that move remains within normal variation and leaves AmeriFreight down 2.3 points from its July baseline of 68.0%. RoadRunner Auto Transport is the only brand whose coverage rose in both tracked months, moving from 16.6% in July to 18.4% in August to 19.6% in September, though the gains are not large enough to register as significant. SGT Auto Transport and Ship a Car Direct each eased modestly across the two-month window, and both remain within normal range.

The most notable pattern in the middle of the field is the narrowing gap between Nexus Auto Transport and RoadRunner Auto Transport, which fell from 17.9 points in July to 6.6 points in September as the two brands moved in opposite directions.

Each monthly run begins with 800 prompt-surface observations (450 unique questions in July, 507 in August, 479 in September) across the benchmark's defined AI/search surface universe. Of those, 799 mentioned a tracked brand or competitor in July and August, and 800 did so in September; 715 were relevant and 84 were irrelevant in July, 711 relevant and 88 irrelevant in August, and 731 relevant and 69 irrelevant in September. The public metrics use 525 qualified observations (July), 555 (August), and 560 (September) that survive both qualification stages.

Key Findings

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The qualified benchmark set is the denominator used for every brand-level percentage in this report; it is a filtered subset of the larger prompt-surface collection shown above, not the raw collection itself.

Benchmark-Level Metrics

The recommendation-shaped answer share declined steadily across the series, from 50.5% in July to 48.1% in August and 42.0% in September, even as the total qualified observation count rose. A larger share of AI responses are now taking forms other than direct recommendation lists, even though the number of responses containing valid recommendation shortlists stayed near 448 in September.

AI Recommendation Trend

Valid Recommendation Coverage by Brand

Only Nexus Auto Transport's baseline-to-current movement exceeds the benchmark's normal range; every other brand's change, including SGT Auto Transport's 5.9-point decline, falls within normal variation. The rank order is unchanged from July, with the gap between Nexus Auto Transport and RoadRunner Auto Transport narrowing from 17.9 points in July to 6.6 points in September as the two brands moved in opposite directions.

• Which transportation services brands moved significantly in AI recommendation coverage this month?
• What does Nexus Auto Transport's two-month coverage decline mean for its recommendation position?
• Which brands showed the strongest rank-one placement gains in September?

Sherpa Auto Transport: Leader Holds, Stable Across the Series

Sherpa Auto Transport's valid recommendation coverage held at 73.8% in September, up 2.6 points from August's 71.2% and down 0.7 points from the July baseline of 74.5% — both changes within the benchmark's normal range. Raw mention presence rose to 85.7% from 83.6% in July.

The top-3 rate moved to 61.8% from 64.6% in July, while rank-one placements held near 5.7%, with 32 placements among 413 valid recommendations. Net sentiment remained near 0.9 across the measured periods.

Sherpa's recommendation coverage has stayed within a narrow band across the series, between roughly 71% and 75%. The benchmark cannot determine which surfaces are driving that stability; a company-level review would need to examine whether Sherpa's presence on Google AI Mode and AI Overviews, where it already holds strong positioning, accounts for the pattern.

AmeriFreight: Largest Monthly Gain, Rank-One Strength

AmeriFreight's coverage moved to 65.7% in September from 62.7% in August, a gain of 3.0 points that remains within its normal range. Against the July baseline of 68.0%, coverage is down 2.3 points, also within normal variation. Mention presence eased to 73.6% from 77.3% in July.

The more notable pattern is at the top of the funnel: AmeriFreight's rank-one rate reached 12.3% in September, up from 8.8% in July, with 69 rank-one placements among 368 valid recommendations — the highest rank-one placement count of any tracked brand this month. Its top-3 rate eased to 43.9% from 48.4% in July. Net sentiment held near 0.9 across both periods.

Coverage and top-3 presence eased across the period while rank-one frequency rose, a combination that points toward fewer but higher-placed recommendations. The benchmark cannot determine which prompts are producing that shift; a company-level review would need to identify which query types now award AmeriFreight the single top recommendation.

Nexus Auto Transport: Significant Decliner, Two-Month Slide

Nexus Auto Transport's valid recommendation coverage fell from 34.5% in July to 29.9% in August to 26.2% in September, a decline of 8.3 points from baseline large enough to register as significant and extending a two-month downward streak. Raw mention presence fell to 34.8% from 42.5% in July. Despite the coverage decline, the top-3 rate held effectively flat at 14.5% versus 14.3% in July, and rank-one placements ticked up slightly to 5.7% from 5.5%, with 32 rank-one placements among 147 valid recommendations.

SGT Auto Transport, the brand directly above Nexus Auto Transport in the September standings, records 51.8% valid recommendation coverage, while Nexus Auto Transport stands at 26.2% — a 25.6-point gap that has widened as the two brands moved in opposite directions across the series. The category leader, Sherpa Auto Transport, holds 73.8% coverage, nearly three times Nexus Auto Transport's current figure. The more important issue is what that gap means for Nexus Auto Transport's recommendation position: because top-3 and rank-one rates held steady while overall coverage contracted, the losses appear concentrated in mid-tier and lower-ranked recommendations rather than in Nexus's strongest placements. Which prompt categories or surfaces account for those disappearing mid-tier placements, and which competitors are absorbing them, is not yet established — and a decline large enough to register as significant, extending across two consecutive months, is not a pattern that can be left unexamined.

RoadRunner Auto Transport: Two-Month Gain, Still Distant From the Leaders

RoadRunner Auto Transport's coverage moved to 19.6% in September from 18.4% in August and 16.6% in July, a two-month upward run totaling 3.0 points from baseline. The movement stays within the benchmark's normal range. Valid recommendation count rose to 110 from 87 in July.

Its top-3 rate moved to 6.4% from 6.1% in July, while rank-one placements fell to 1.4% from 3.0% in July. Net sentiment moved to 0.5 from 0.4 in July.

RoadRunner is the only tracked brand whose coverage rose in both measured months, yet it remains roughly 32 points behind the brand directly above it in the standings — the distance between its 19.6% coverage and SGT Auto Transport's 51.8%. The benchmark cannot determine whether RoadRunner's gain reflects broader presence or stronger placement, since rank-one frequency has not kept pace with coverage; that distinction is a question for company-level analysis.

SGT Auto Transport and Ship a Car Direct: Middle and Tail Ease

SGT Auto Transport's coverage moved to 51.8% in September from 56.2% in August and 57.7% in July, a two-month downward drift of 5.9 points from baseline that remains just within the benchmark's normal range. Mention presence fell to 57.9% from 64.2% in July. Its top-3 rate eased to 19.3% from 24.2% in July, and rank-one placements slipped to 1.1%, with 6 placements among 290 valid recommendations. Net sentiment held near 0.9 across both periods.

Ship a Car Direct's coverage moved to 11.4% from 12.0% in July, with 64 valid recommendations. Its top-3 rate eased to 3.9% from 5.1% in July, and rank-one placements held near 1.1%, with 6 placements. Both brands' movements fall within normal variation given their small absolute counts.

For SGT Auto Transport, presence and coverage eased together across the two-month window, a broader pattern than a single-slot shift; the benchmark cannot determine which surfaces are contributing least. For Ship a Car Direct, the counts are small enough that its stable low coverage could reflect either a structural presence gap or ordinary variation; company-level analysis would be needed to distinguish between the two.

Buyer-Intent Interpretation

Questions This Section Answers

• Which buyer-intent clusters does this benchmark actually measure for transportation services?
• Why can't the current benchmark answer pricing or comparison questions?

In September 2026, all 560 qualified observations fell into the Brand Recommendation cluster, matching the pattern across July and August when all qualified observations landed in that class. The public benchmark therefore continues to measure how AI systems choose and rank providers when asked directly, but it cannot yet answer pricing, value, or head-to-head comparison questions: those prompt classes produced no qualified observations in any measured month. Brands that compete on cost or feature trade-offs are not being tested at the category level by this benchmark's current prompt mix.

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations carrying query, surface, recommendation outcome, rank, sentiment, and citations where exposed. Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns to explain why a brand appears where it does in AI responses, which sources AI systems cite, and how competitive framing shifts across prompt types. Source presence is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• Small-count movements: Nexus Auto Transport's 147 valid recommendations and Ship a Car Direct's 64 rest on small absolute numbers; a handful of prompts can account for meaningful share movement, which is a reason for caution rather than a definitive conclusion.
• Qualified denominator: all percentages use the 560 qualified observations in September, not the 800 prompts collected; the research-stage table above shows the full qualification path.
• Directional analysis: month-over-month movement identifies changes worth investigating; it does not by itself establish cause. Only Nexus Auto Transport's coverage decline from baseline exceeded the benchmark's normal range.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath the aggregate coverage percentages sit the questions that matter most: which high-intent prompts a brand wins, which competitor takes the recommendation when a brand loses, what attributes AI systems associate with each option, and which external sources shape those answers. For a brand like Nexus Auto Transport, the benchmark shows a significant decline from baseline, but it cannot yet show which prompts or surfaces drove it; for AmeriFreight, the benchmark shows rank-one strength, but not which evidence sources support it. Understanding those patterns is the difference between knowing a brand moved and knowing why it moved.

A company-specific AI visibility audit maps prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy, giving brands a clear picture of where they hold authority, where they leak recommendations, and what to address first.
