An r/SEO_LLM thread wanted SEO data for 300 client domains without surprise overage. This walks the DataForSEO + Ahrefs + Scavio stack.

Prerequisites

  • DataForSEO account ($50 min top-up)
  • Ahrefs Standard plan ($249/mo)
  • Scavio API key

Walkthrough

Step 1: DataForSEO for daily rank tracking SERP at scale

$0.60/1K standard queue.

Text
// 300 domains × 50 keywords × daily = 15K queries × $0.60/1K = $9/day = $270/mo for SERP
// POST https://api.dataforseo.com/v3/serp/google/organic/task_post

Step 2: Ahrefs Standard for backlink + content depth queries

Use credits judiciously.

Text
// Ahrefs Standard: 500 monthly credits + Content Explorer.
// Reserve credits for the deep-dive queries; don't burn on routine rank checks.

Step 3: Scavio for AEO/AI Overview citation tracking

Underserved by classic SEO platforms.

Text
// POST https://api.scavio.dev/api/v1/search
// Body: { query, include_ai_overview: true }

Step 4: Roll up to client dashboards weekly

Same query schema across 300 clients.

Text
// Postgres / BigQuery: rank_tracking, ai_overview_citations, backlinks, keyword_rankings

Step 5: Per-client report generation

Templated, automated.

Text
// LLM-generated narrative: 'Client X's keyword Y dropped 3 positions; AI Overview now cites competitor Z. Recommended action: ...'

Step 6: Honest cost monitoring

PAYG can creep.

Text
// Monthly: review DFS spend vs forecasted. If queries grew 30%+, review which clients are hot.

Python Example

Python
# Per-client-month: ($270 DFS + $249 Ahrefs + $30 Scavio) / 300 = $1.83/client/mo data cost.

JavaScript Example

JavaScript
// Same in TS.

Expected Output

JSON
Daily rank-tracking + weekly backlink + monthly AEO snapshot for 300 client domains, under $600/mo total data cost.
