Ahrefs calculates "Traffic Value"—the estimated cost of buying equivalent traffic through Google Ads based on CPC for each ranking keyword. This monetary value helps prioritize keywords and estimate SEO ROI in dollars. The tool shows traffic potential if you ranked #1 for all target keywords, revealing maximum upside. CTR curves model realistic click-through rates by position accounting for SERP features. For teams needing to communicate SEO value in monetary terms stakeholders understand, Ahrefs' traffic value approach works better than abstract visitor counts.

Traffic Value shows monetary worth in dollars
Traffic potential reveals maximum upside
CTR curves account for SERP features realistically
Competitor traffic value for benchmarking
Integration with Ahrefs keyword and content tools
Limitations
Requires Ahrefs subscription ($99+ monthly)
Less scenario modeling than dedicated forecasting tools
CPC-based value estimates vary by industry
Who it's for: Perfect for SEO teams presenting to executives who think in revenue terms. If stakeholders ask "what's the ROI?", showing traffic worth $50K/month in PPC costs is more compelling than "10,000 monthly visitors."
Moz Keyword Explorer provides a "Priority" score combining search volume, ranking difficulty, and organic CTR opportunity.

Common Questions
Good forecasting tools achieve 70-85% accuracy for 6-month projections when based on solid ranking data and realistic scenarios. Accuracy improves for: 1) Smaller ranking jumps (position #8 to #5 vs. #50 to #1), 2) Stable search volumes, 3) Keywords you already rank for. Forecasts are directional—use ranges (conservative, realistic, optimistic) rather than exact numbers.
Essential data: 1) Current keyword rankings, 2) Search volume per keyword, 3) Historical traffic from Google Analytics, 4) Conversion rate (for ROI), 5) Average order value or lead value. More data improves accuracy—seasonal trends, SERP features, and competitive changes all affect projections.
Forecast both: traffic for SEO teams, revenue for executives. Traffic projections ("we'll gain 10,000 monthly visitors") mean little to CFOs. Revenue projections ("worth $50K in PPC or $25K in sales") justify budgets. Always connect traffic to business outcomes using conversion rates and customer value.
Use competitor data as proxies. Find similar sites ranking for your target keywords, estimate their traffic using tools like Ahrefs, and model your potential. Alternatively, focus on keyword difficulty and search volume—high-volume, low-difficulty keywords offer best ROI for new sites. Forecasts are less accurate but still valuable for planning.
Common mistakes: 1) Assuming linear growth (rankings don't improve steadily), 2) Ignoring SERP features (featured snippets steal clicks), 3) Using inaccurate search volumes, 4) Not accounting for seasonality, 5) Forecasting position #1 for impossible keywords. Always model conservative, realistic, and optimistic scenarios—not just best case.
