Answer engine optimization6.2M pages · 3,332 sites
Pages that do beat pages that explain.
We sorted 6.2 million pages from 3,332 sites by what they are: free tools, comparisons, listicles, how-tos, definitions. Then we compared each format with articles on the same site, at the same Google position. Answer engines summarize pages that explain. They send clicks to pages that do.

On 74% of the 328 sites that had both, a free tool ranking 4th to 10th was clicked more often than a blog article at the same position. Further down, at positions 11 to 20, the gap widens to 2.42×: people scroll past ten summaries to reach a calculator.
At the other end, “what is” pages earned 0.52× the click-through of a site’s other articles across 326 sites, and only 23% of those sites had definitions doing better. At positions 11 to 20 it falls to 0.42× with 17% winning. A definition is exactly what an AI Overview prints at the top of the page.

This is the zero-click economy on one chart. Articles of every kind are shown constantly: they answer the questions, they feed the AI summaries, they build topical authority. But the clicks pool on pages people need to use: tools, homepages, product and category pages. Both lines matter. Only one of them is traffic.
The raw numbers
At positions 4 to 10, a tool converts 1 impression in 22 into a click. A definition, 1 in 357.

Our take
Answer engines eat explanations. Keep publishing them to be the source AI quotes, and build tools to be the page people still visit.
Most content strategies still look like 2019: a definition, a how-to, a top-ten list, repeat. The data shows that mix now produces impressions for Google and training material for chatbots, and fewer visits every month. It is not wasted. It is just no longer the whole job.
This is why Outrank builds free tools as well as articles. See the tools builder and the zero-click study for the bigger picture.
- 01
Write articles to be cited
Specific, quotable, sourced. Measure them by impressions and AI citations, not by clicks alone.
- 02
Ship one free tool per money keyword
A calculator, checker or generator next to your best article. Fewer than half the sites we studied have one.
- 03
Link the two
Let the article earn the citation and hand the reader to the tool. That is where the click and the conversion happen.
The case against
4 reasons to discount these numbers
Every dataset has blind spots. These are ours, stated plainly.
URLs are a rough classifier
We sorted pages by their URL, not their content. A product page called “invoice-generator” counts as a tool. 51% of sites had at least one “what is” page, which is enough for a fair comparison but misses definitions with other slugs.
Tools often are the product
On many SaaS sites the “generator” page is the product itself, with strong intent behind it. That inflates the tool advantage, which is also the point: pages that do something get clicked.
Sixteen months in one number
Page metrics cover 16 months, so a page that ranked differently over time is averaged out. Average position is impression-weighted.
Clicks are not citations
This study measures clicks. A definition with no clicks may still be the page an AI quotes. That trade-off is the subject of our AI citation study.
Methodology
How we ran the numbers
- Data: page-level clicks, impressions and average position over 16 months from Google Search Console, for 3,332 sites connected to Outrank: 6,208,782 pages.
- Classification: by URL. Tools: calculator, generator, checker, converter, counter, estimator, planner, maker, quiz, finder or tracker in the slug, or a /tools/ path. Comparisons: “vs”, “versus”, “alternatives”. Listicles: slugs starting with “best” or “top”. How-tos, definitions (“what is”) and questions by their first words. Other blog articles by blog-like paths.
- Fair comparison: the headline multipliers compare each format with the same site’s other blog articles, inside the same position band (4 to 10, and 11 to 20), so site size, niche and authority cancel out. A site counts only if it has at least 500 impressions in both groups.
- Pooled shares: the impressions and clicks shares add up every page, so large sites weigh more. They show where the clicks are, not what a typical site sees.
