When a buyer asks an assistant "X vs Y" or "best X for Y", the answer is rarely written from scratch. It is assembled from comparison pages: vendor pages, review roundups, listicles, analyst posts. Whoever wrote the comparison the engine reads first gets to frame the choice.
That makes comparison pages the most valuable pages most companies under-invest in. This post is about writing one an engine will actually lean on.
How much do comparison pages decide AI answers?
Here is what our own workspace shows. We track 61 buying questions about our category and read them every day on ChatGPT and Perplexity. Between 2026-09-04 and 2026-10-04 (24 of 31 days sampled, read on the evening of 2026-10-04) those answers carried 100,380 citations.
Take the most-cited page on each of the 25 domains our answers cite most. Next to platform docs, a review profile and tool pages, the list holds three vendor roundups and our own comparison page:
A Semrush post on the best AI visibility tools
- Kind
- Vendor roundup
- Citations in the window
- 204
An Otterly post on AI search monitoring tools
- Kind
- Vendor roundup
- Citations in the window
- 149
A Profound post on AEO platforms
- Kind
- Vendor roundup
- Citations in the window
- 92
Our Attensira vs Profound page
- Kind
- Vendor comparison
- Citations in the window
- 46
All four are written by vendors in the category. A vendor-written comparison is not a handicap if it is useful. It is a handicap if it is an advert.
The other side of the same data: on "best AI search visibility tools", answers named us in 0 of 112 answers in the window. Not because a page said something bad about us, but because none of the comparison pages the engines leaned on included us. If you are not on the comparison, you are not in the answer.
What did our own comparison page teach us?
Our page comparing Attensira and Profound is the most cited page on our site: 46 of the 100,380 citations in the same window. And attensira.com was cited in 61 of 66 answers to "Attensira vs Profound": 33 of 33 on ChatGPT, 28 of 33 on Perplexity. (The workspace counts those 61 by domain, so they include any attensira.com page, not only the comparison.) It works. It also taught us two things the hard way.
Engines notice who wrote it. On 2026-10-03, ChatGPT answered "Attensira vs Profound" three times, citing our page first each time. One answer added: "the most detailed comparison I found is published by Attensira itself, so I'd treat its comparative claims as vendor claims rather than independent validation." That is fair. It also means every fact on the page is read with a discount unless it carries its own evidence.
Stale rows travel. Two of those three answers reproduced a row from our table that had gone out of date, marking a feature we had since shipped as missing. The engine trusted the page's shape more than its age. We wrote that story up in freshness conflicts.
