Ahrefs urges agencies to use median SEO traffic benchmarks, not averages

Ahrefs used anonymized Google Search Console data from 422,421 real websites to argue that agencies should stop treating one traffic number as a universal SEO target. The June 23 benchmark measured Google organic clicks from the latest complete month, not total visits or traffic from paid, direct, or social channels, and it was built to show how uneven search demand really is.

The core warning was simple: the mean can mislead. Ahrefs said giant sites such as Wikipedia and Amazon can pull averages up and make typical performance look stronger than it is, so the median is a better starting point for client conversations. That matters when agencies are building benchmark decks, because the more useful question is not how much traffic a site should get in the abstract, but where it sits relative to its peer group, category, authority level, and age.

Ahrefs paired that traffic work with a June 22 CTR benchmark that put whole-site organic clickthrough rates mostly between 1% and 2%, while noting that industry, authority, and website size all moved the number materially. The company said that benchmark is refreshed every month by Agent A, which makes it a moving reference rather than a fixed table. In practical agency terms, that pushes retainers toward percentile-based expectations, with reporting framed around ranges and site maturity instead of a single “average” line that can be gamed by outliers.

The pressure on those expectations is increasing because AI search is changing how many clicks actually reach a site. Ahrefs’ February 4 update said AI Overviews correlated with a 58% lower average clickthrough rate for the top-ranking page in its December 2025 analysis, up from a 34.5% drop in its April 17, 2025 study. Google said AI Overviews were available in more than 200 countries and territories and more than 40 languages, said in August 2025 that it still sends billions of clicks to the web every day, and said by July 2025 that AI Overviews had reached 2 billion monthly users. At Google I/O 2026, Sundar Pichai said that figure had passed 2.5 billion monthly active users.

That backdrop makes Ahrefs’ benchmark useful as a client education tool. Agencies can use it to show why a mid-sized site with steady gains may look flat against a site in a different authority band, why traffic alone no longer captures visibility, and why Google’s June 3, 2026 Search Console generative AI performance reports, which include impressions for AI Overviews and AI Mode, now belong in the measurement stack alongside classic organic reporting.
