Digital Marketing Agency: AI Market Discovery Index

Benchmark Summary

SmartSites remained the category leader in the Digital Marketing benchmark in August 2026, holding valid recommendation coverage of 58.7%. That figure was essentially unchanged from 62.1% in July 2026 — a difference within normal month-to-month variation. The gap to the second-place brand, LYFE Marketing, stood at 31.1 percentage points, with LYFE Marketing at 27.6% coverage.

Cardinal Digital Marketing was the only tracked brand whose valid recommendation coverage moved beyond normal month-to-month variation this month, falling from 8.0% in July 2026 to 5.1% in August 2026, a decline of 2.9 percentage points. AIS Media posted the largest increase among tracked brands, rising from 1.6% to 2.1%, though that change remained within normal variation. The remaining tracked brands were stable on this measure.

The qualification funnel produced 584 qualified benchmark observations in August 2026, up from 573 in July 2026.

Current Benchmark at a Glance

Qualified surface breadth counts the canonical AI/search surface families with at least one qualified observation: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode. All six families were represented in both months.

Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design.

Brand-level percentages use the qualified observations as the public denominator, not the raw collection. See the AI Market Discovery Methodology for full details.

Current Brand Standings

How to Read the Standings

• Presence rate: share of qualified observations where the brand appears in any form.
• Valid recommendation coverage: share of qualified observations where the brand receives a valid recommendation.
• Top-three rate: share of qualified observations where the brand appears in the top three recommended positions.
• Rank-one rate: share of qualified observations where the brand is the top-ranked recommendation.
• Net sentiment: positive mentions minus negative mentions divided by total mentions, scored from -1 to 1.

Grater Digital: Current Position

Grater Digital holds 0.0% presence rate, 0.0% valid recommendation coverage, 0.0% top-three rate, 0.0% rank-one rate, and 0.0 net sentiment in the August 2026 benchmark. Per the Recommendation Coverage Movement data below, this is unchanged from the July 2026 baseline, meaning Grater Digital has not yet registered a single qualified appearance, recommendation, or ranked placement across the 584 qualified observations measured this month.

SmartSites records 58.7% valid recommendation coverage, while Grater Digital stands at 0.0%. The more important issue is what that gap means for Grater Digital's recommendation position: across the two months measured, the category leader has been recommended in well over half of qualified observations, while Grater Digital has not been recommended, placed in a top-three position, or measured with any sentiment in a single one. This is a material gap on the benchmark's primary commercial metric, and it has shown no movement in either direction since the baseline period.

Highest-priority diagnostic: Why does Grater Digital have zero qualified presence, recommendation, or placement across all tracked AI/search surfaces in both measured months, and what would be required to establish even initial, measurable visibility on this benchmark?

Recommendation Coverage Movement

Largest Decline: Cardinal Digital Marketing

Cardinal Digital Marketing fell from 8.0% valid recommendation coverage in July 2026 to 5.1% in August 2026, a drop of 2.9 percentage points that moved beyond normal month-to-month variation. The decline was accompanied by a fall in presence rate from 8.2% to 5.5%, while the rank-one rate also slipped from 1.8% to 0.9%. The top-three rate moved slightly higher, from 3.1% to 3.6%.

Category Leader: SmartSites

SmartSites remained the category leader in August 2026 at 58.7% valid recommendation coverage, down from 62.1% in July 2026. The decline was within normal month-to-month variation. Presence rate rose from 70.7% to 71.8%, and top-three rate edged up from 43.1% to 43.3%, while rank-one rate dipped from 22.3% to 22.1%.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. Among the two leading brands, SmartSites held a top-three rate of 43.3% in August 2026, essentially level with 43.1% in July 2026. LYFE Marketing's top-three rate was 19.0% in August 2026, down from 20.4% in July 2026.

Even where coverage is similar, first-position rates can differ meaningfully, so placement matters alongside raw coverage.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class.

The current public series measures Brand Recommendation discovery only and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Historical Measurement Record

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

• Market share or sales attribution
• Every possible AI response to every possible query
• Organic-search ranking positions
• Social media mention volume
• Private or sponsored channel performance
• Causality from a metric movement alone
