How to measure a keyword's true traffic potential using Ahrefs

Executive overview

Search volume for a single keyword consistently underestimates the traffic an article can actually receive. A top-ranking page typically ranks for around 1,000 related keywords, not just the one you targeted. The real traffic signal is not search volume — it is the total organic traffic of top-ranking pages for that topic.

Search volume is a poor proxy for traffic potential; look at what top-ranking pages actually earn.

Why search volume misleads

• Search volume figures come from Google Keyword Planner, which shows rounded annual averages — not precise counts
• Ahrefs supplements Keyword Planner data with clickstream data for better accuracy, but numbers remain estimates
• A keyword with 150 monthly searches can drive 100+ visitors per month due to rankings across related queries
• The #1 result captures ~30% of clicks, #2 ~15%, #3 ~10% — but these percentages shift based on query type

How to find real traffic potential

• Open the SERP overview in Ahrefs Keywords Explorer for your target keyword
• Check the Traffic column for top-ranking pages — this reflects all organic traffic, not just from one keyword
• Click the keyword count for any page to see every query it ranks for in Organic Keywords (Site Explorer)
• Filter by top-3 positions to focus on traffic-driving rankings only
• Compare the top-ranking pages themselves: depth and coverage directly affect how many related keywords a page ranks for

Key insight: depth drives rankings breadth

• A shallow list page ranked #1; a detailed forum discussion ranked #2 — yet the #2 page got 3x more traffic
• Richer, more comprehensive content gives Google more to index across related queries
• Better topic coverage leads to more keyword rankings and higher total traffic
