n8n Workflow: Track Organic SEO Market Share with DataForSEO

Track Organic SEO Market Share Every Week—Powered by DataForSEO + n8n

This n8n workflow automatically finds your organic search competitors with DataForSEO, estimates their traffic and market share, compares changes to prior runs in Google Sheets, and then generates a clear narrative report in Google Docs—which it emails to you via Gmail.

What this workflow does

• Runs weekly: scheduled to run every Monday morning.
• Discovers competitors: calls the DataForSEO Competitors Domain endpoint for your site, filtering out your own domain and common platforms (unless you provide a pinned competitor list).
• Estimates traffic & market share: requests DataForSEO Bulk Traffic Estimation for the full peer set and reads prior snapshots from the history tab in Google Sheets.
• Calculates changes: computes estimated visits, share of the peer set, and share change since the most recent run, flagging domains that are new or gained meaningful share.
• Enriches insights:
  • For domains that gained share: fetches DataForSEO Relevant Pages to identify top pages driving the increase.
  • For newly detected competitors: fetches DataForSEO Domain Rank Overview for a one-time profile note.
• Creates a report + table: uses OpenAI to draft a short plain-text market note, then builds a Google Doc with a title, fixed-width table, and narrative.
• Sends and stores results: emails the Google Doc link via Gmail and appends one row per domain to the Google Sheets history tab for next week’s comparison.

Use cases
