For years, the SEO planning template was the same spreadsheet trick: pull the keyword volume, multiply by an assumed CTR (the famous "31% for position 1"), and call that your traffic projection. In 2026, that math is broken.
What changed:
- AI Overviews sit above the organic results on most informational queries. The user often gets their answer in the box and never scrolls.
- Featured snippets still steal the click on definitional / how-to queries.
- People Also Ask clusters expand inline and burn 6-8 vertical inches of SERP real estate.
- Sponsored carousels on commercial intent queries push the first organic result below the fold on mobile.
The result: position 1 organic CTR for an informational keyword in 2026 is closer to 8-15% than to the legacy 30%. For commercial-intent keywords with a sponsored carousel and an AI Overview, position 1 organic CTR can drop to 3-6%.
If you're still planning content with a 30% assumption, your traffic forecasts are off by a factor of 3-10x. Which means the keyword you're killing for "low projected upside" might actually be the one worth shipping, and the keyword you're prioritizing for "30% × 12k searches" is going to disappoint.
What I changed in my own planning
I split CTR assumptions into 4 SERP archetypes:
| SERP type | Position 1 CTR (2026) | Position 2-3 CTR |
|---|---|---|
| Plain organic (rare) | 28-35% | 12-18% |
| Organic + PAA only | 18-24% | 8-12% |
| Organic + AI Overview | 8-15% | 3-7% |
| Organic + AI Overview + sponsored carousel | 3-6% | 1-3% |
Before committing to a topic, I run the SERP through a quick check: which archetype is it? Then I plug the right CTR into the volume math. That single change cut the gap between my projected and observed traffic by ~70%.
A free thing for the lazy version of you
I built a free in-browser calculator that does this for you — paste the keyword + chosen position + SERP archetype, get a realistic click projection: the-seo-autopilot.com/en/free-tools/serp-ctr-calculator. No signup, all client-side, no email gate. Use it when you're triaging a 200-keyword list and don't want to manually classify every SERP.
There's also a related one I use a lot — a keyword opportunity calculator that combines this CTR adjustment with difficulty / volume / business value to spit out a single ranked score per keyword. Useful when you have a backlog of 50 ideas and need to pick the next 5.
TL;DR
- The "30% for position 1" rule of thumb is a 2018 number. Don't plan with it in 2026.
- Classify each keyword's SERP into one of 4 archetypes before assigning a CTR.
- AI Overviews + sponsored carousels can drop your effective CTR by 5-10x.
- Recalibrate. Your "low-volume but high-intent" keywords are probably more valuable than your "high-volume informational" ones now.
Plan your content with the SERP you actually have, not the SERP you wish you had.
