In short
- Reweighting
- The same factors, different weight. What weighed heavily in SEO sometimes weighs less in GEO — and the other way round.
- Authority persists
- The factor that holds up in both paradigms. Anyone who has built authority does not throw it away by switching.
- New signals
- Generative signals come on top, they do not replace the old ones. That is an addition, not a swap.
- Divergence index
- The measure the study uses to express how far a factor in GEO departs from its place in SEO.
What does the study say?
The comparison is built from existing material — among others the Princeton GEO study, an Ahrefs analysis across 75,000 brands, Backlinko and Semrush — and that is exactly the gain: it puts findings that otherwise circulate separately onto one scale.
| What was measured | How | What the study does not say |
|---|---|---|
| SEO and GEO factors on one scale | cross-paradigm comparison with a divergence index, based on existing research (Princeton, Ahrefs, Backlinko, Semrush among others) | which weight an engine applies today exactly — no engine publishes that |

Why does this matter to you?
Because it prevents the most expensive mistake of the moment. Dropping your SEO to “move to GEO” loses you the authority that counts in both. And assuming good SEO automatically yields good GEO misses the signals that have newly appeared.
What does ceeme do with it?
We measure both in one scan and deliver fixes for both. A technical SEO fault — a blocked crawler, a broken canonical — lands at the top of our report, because it makes every GEO effort above it pointless.
Frequently asked questions
So is SEO over?
No, and the study says so explicitly. It argues for reweighting, not replacement. Anyone claiming the opposite while citing this research has not read it.
Do I need two budgets then?
One budget and one order. The technical base serves both, so you pay for it once. Above that the work differs: SEO steers for positions in a list, GEO for citability in an answer.
Can bad SEO damage my GEO?
Yes, and the clearest case is also the silliest: a site that shuts out AI crawlers cannot be cited. No content tactic fixes that, and it takes one line to solve.
