Grounding with Google Search costs $14 per 1,000 queries (after 5,000 free/month).

Perplexity Sonar

Sonar$1.00$1.00$5-12
Sonar Pro$3.00$15.00$6-22
Sonar Reasoning Pro$2.00$8.00$6-14
Perplexity charges both token costs AND per-request fees. Total cost per query = tokens + request fee.

2. Cost Per Query Comparison

Assuming a typical brand monitoring query: ~100 input tokens (system prompt + question), ~500 output tokens (response with recommendations):

ModelCost/QueryAnnual (18K queries/mo)
GPT-4.1-nano$0.0002$43
Gemini 2.5 Flash-Lite$0.0002$43
GPT-4o-mini$0.0003$65
Gemini 2.5 Flash$0.0013$281
Claude Haiku 4.5$0.0026$562
Perplexity Sonar (+ request fee)$0.0006 + ~$0.008$1,858
GPT-4o$0.0053$1,145
Claude Sonnet 4.6$0.0078$1,685
The cheapest viable models (GPT-4.1-nano, Gemini Flash-Lite) cost ~25x less per query than flagship models (Sonnet 4.6, Sonar Pro). This gap is the foundation of the cost optimization strategy.

3. Monthly Cost Modeling

Scenario A: Small Brand Monitoring (10 brands)

10 brands × 5 queries × 4 models × 3 samples × daily = 18,000 queries/mo

StrategyMonthly Cost
All GPT-4.1-nano$3.60
All GPT-4o-mini$5.40
All GPT-4o$95.40
All Claude Sonnet 4.6$140.40
Mixed: nano/Flash-Lite polling, GPT-4o deep dives (90/10)~$13
With Perplexity Sonar (add request fees)$50–80

Scenario B: Enterprise (100 brands)

100 brands × 10 queries × 4 models × 5 samples × daily = 600,000 queries/mo

StrategyMonthly Cost
All GPT-4.1-nano$120
All GPT-4o$3,180
All Claude Sonnet 4.6$4,680
Mixed budget (95/5 split)$350–500
With batch API (50% off)$175–250

Recommendation

Moderate spend. Enable the tiered strategy and batch API to cut costs by 80-95%.

Enable Batch API for an easy 50% savings on non-urgent daily polls.

4. Cost Optimization Strategies

Tiered Model Strategy (90-95% savings)

The single most impactful optimization: use cheap models for routine polling, expensive models only for targeted analysis when changes are detected.

There is a 500x–1,000x spread in per-prompt pricing across the market. Profound charges ~$9.98/prompt for what costs <$0.01 in raw API calls. The value is in parsing, analysis, dashboarding, and insights layered on top.

6. Comparison to Traditional SEO Tools

Ahrefs Standard$249/moFull suite (up from $179)
Ahrefs Enterprise$1,499/moEnterprise (50% increase over 2025)

Semrush (NASDAQ: SEMR) benchmarks: Average ARR per customer $3,522 (~$294/mo). Customers paying >$50K/year grew 72% YoY. Total ARR: $455.4M (+14% YoY). AI product ARR contribution: $10M in Q3 2025 alone (doubling quarter-over-quarter).

7. Break-Even Analysis for GEO SaaS

Break-even customers~870~410
Time to break-even (est.)~36 months~22 months
The market sweet spot is $79–149/month for most teams. At $199/mo with optimized API costs ($0.0002–0.002/query), approximately 230 customers reach break-even at ~month 22. The 500x–1,000x markup over raw API costs demonstrates strong unit economics potential.
