1. Aveeno appeared beyond one moisturizer question
We asked: “Which fragrance-free facial moisturizers should I compare for a basic routine?” We saved 12 Perplexity responses to that one question. Aveeno appeared as a comparison option in all 12. It shared that recurring set with CeraVe, Vanicream, La Roche-Posay, Neutrogena and Thayers. One answer named Aveeno Calm + Restore Oat Gel Moisturizer.
Its presence extended into other tasks. We also read the first Perplexity answer to each of the study’s 30 questions. In that one-answer-per-question view, Aveeno was an option in answers to three different questions: a simple-routine brand comparison, fragrance-free moisturizers and body lotion.
That makes it an example of a competitor crossing product contexts. The three-question snapshot establishes that range; it does not establish Aveeno’s recurrence across every answer to those other questions. [S02]
2. Thayers was a recurring moisturizer alternative
Thayers also appeared in all 12 repeated Perplexity answers to that same fragrance-free moisturizer question. The first saved answer included Barrier Bestie Ultra Whip Cream in its product table.
Yet that same answer’s initial three-product shortlist named Vanicream, CeraVe and La Roche-Posay. Thayers belonged to the wider comparison without occupying that opening shortlist.
The distinction is useful for competitive analysis. An untracked brand can recur consistently without displacing the familiar leaders from every favored position. Both the competitor’s presence and its place in the advice matter. A ten-name chart would contain no row for Thayers at all. [S03]
3. Innisfree joined the sunscreen comparison every time
For sunscreen, we asked: “Which facial sunscreens should I compare if white cast and a greasy finish are my main concerns?” We saved 16 Perplexity answers to that single question. Innisfree appeared in all 16, alongside recurring tracked names such as Supergoop, Neutrogena and Colorescience.
In the first answer, Innisfree Daily UV Defense appeared in both the product table and the final starting shortlist. That is a more specific observation than a name appearing somewhere in a response.
For a sunscreen marketer, this is evidence of a recurring comparison rival in one defined shopping task. It is not independent confirmation of the answer’s descriptions of the product’s finish. [S04]
4. ISDIN appeared just as often, with a different placement
ISDIN also appeared in those 16 Perplexity answers to the same white-cast-and-greasy-finish question. In the first record, Eryfotona Actinica appeared in the comparison table but was absent from the final starting shortlist that included Innisfree.
The two brands therefore shared the same full-case recurrence while occupying different positions in that particular answer. Neither the count nor one final shortlist tells the whole story.
A competitive review can retain both observations: ISDIN was repeatedly offered for comparison, and the inspected answer narrowed its final choices differently. There is no need to turn either observation into a claim about sales, consumer preference or product superiority. [S04]
5. Banana Boat entered through routine and budget questions
Two different questions brought Banana Boat into view: which brands to consider for a simple routine, and which products to compare for a basic routine with a total budget of $50. For this example, we read the first Perplexity answer to each question—two answers, not a frequency count across the whole study.
In the budget record, Banana Boat sat among sunscreen alternatives alongside Neutrogena, CeraVe and a store brand. It did not need to headline a dedicated sunscreen question to enter the consideration set.
This is a narrower finding than the all-answer moisturizer and sunscreen counts above: two selected records, not a quantified frequency across the entire collection. It still identifies a competitor that the ten-brand dictionary did not cover. [S05]
6. Eucerin reached the top of one final shortlist
We also examined one ChatGPT answer to the same sunscreen question about white cast and a greasy finish. That saved answer put Eucerin Clear Skin first in its final three-product recommendation, ahead of two Supergoop products. The same answer also discussed La Roche-Posay.
That is a consequential omission for a tracker focused only on the selected ten brands: an untracked product occupied the first position in this saved answer’s closing shortlist.
One answer does not make Eucerin the study’s sunscreen winner. It does establish why competitor discovery belongs beside a fixed brand scorecard. Otherwise, a report can describe the tracked brands’ relative positions while overlooking the name above them. [S06]
These six examples widen the competitive map without pretending to complete it. The practical analytical step is to inspect which additional products enter the tasks that matter to the business, then decide whether they belong in ongoing tracking. The study did not test whether changing website content would change those results.
Methods and evidence
These cases use ChatGPT and Perplexity API answers collected October 9, 2026, within a 30-question authored study. Full-case and one-answer-per-question snapshot counts are labeled separately. Perplexity’s 12 moisturizer texts share one citation set; its 16 sunscreen texts use two. Recurrence does not establish independent retrieval. Product claims, prices and availability were not independently validated. Semantic review was selective, not full double-coding.
