AI Shelf Index: Who Writes AI Gift Advice
The Sourcelift AI Shelf Index (Holiday 2026) found that 26 of 36 ChatGPT answers to common US holiday gift questions (72%) did not cite a single brand’s own website. A third of the 66 sources ChatGPT cited were registered in the past year, only 13 belonged to brands, and 30 of the 50 independent brands we tracked were never recommended in their own category.
The AI Shelf Index measures where the gift advice that AI assistants give US shoppers comes from, and which brands make the list. This first edition covers 40 common holiday gift questions across five categories, asked to ChatGPT on October 5, 2026.
What did the AI Shelf Index find?
- A third of the sources were less than a year old. 22 of the 66 websites ChatGPT cited (33%) were registered in the past 12 months, according to public domain records.
- Nearly 3 in 4 answers cited no brand website. 26 of the 36 answers that showed sources relied only on review sites, publications and retailers.
- Brands were a small share of the sources. 13 of the 66 websites ChatGPT cited (20%) were brands’ own sites.
- Independent review sites were the largest group. 28 of the 66 sources (42%) were independent review and gift-guide sites, ahead of established publications (21).
- 30 of the 50 independent US brands we tracked were never recommended in their own category. 20 were named at least once.
- Specialist categories lean hardest on small review sites. 7 of 8 coffee answers cited at least one.
- Prices were not the problem. Every price we checked against the brand’s own site matched. The gap is visibility, not accuracy.
Which sources does ChatGPT cite for gift advice?
| Source type | Websites cited | Share |
|---|---|---|
| Independent review and gift-guide sites | 28 | 42% |
| Established publications | 21 | 32% |
| Brands’ own websites | 13 | 20% |
| Retailers and marketplaces | 4 | 6% |
| Total | 66 | 100% |
How does it change by category?
| Category | Answers with sources | Cited a brand’s own site | Cited an independent review site |
|---|---|---|---|
| Coffee | 8 | 3 | 7 |
| Kitchen and cookware | 7 | 1 | 4 |
| Jewelry | 6 | 3 | 3 |
| Candles and home fragrance | 8 | 2 | 3 |
| Bedding and loungewear | 7 | 1 | 2 |
| Total | 36 | 10 | 19 |
Lifestyle categories that national magazines cover every holiday season, such as candles and bedding, leaned on established publications. Specialist categories, such as coffee gear and kitchen tools, leaned on small independent review sites. In coffee, three review sites from the same publisher appeared in half of the answers.
Review sites are a normal part of shopping, and most disclose how they earn money. The point of the Index is visibility: a shopper sees one confident answer, not the sources behind it, and an independent brand that those sources do not cover can be left out of its own category.
Does Google AI Mode do the same?
Less so, in a smaller check. Across 9 coffee questions, Google AI Mode cited retailers and brand sites more often than ChatGPT did, alongside the same kind of independent review sites.
What can brands do before the holidays?
These are the steps Sourcelift recommends to brands that want to be named in AI gift answers:
- Ask the questions your buyers ask. Run your category’s top 10 gift questions in ChatGPT, Google AI Mode and Perplexity, and write down which sites each answer cites.
- Get on the pages AI already reads. Review sites accept product information like any publication. Send accurate specs, prices and photos to the sites that show up in your category.
- Make product facts easy to read. Put price, stock, materials and dimensions in plain text and in Product structured data on your own pages.
- Publish what only you can say. First-hand tests, sizing data and real customer questions give AI something to cite that a spec-sheet review cannot.
- Measure every month. AI answers change between sessions, so one check is a snapshot, not a position.

How was the study run?
- Questions: 40 holiday gift questions written the way US shoppers ask them, 8 per category, for example “Best cast iron skillet to give as a gift”.
- Engine: ChatGPT, logged out, from a US connection, one new session per question, on October 5, 2026. Google AI Mode was checked on 9 coffee questions as a comparison.
- Sources: every website shown in ChatGPT’s citations, classified as a brand’s own site, a retailer, an established publication, or an independent review or gift-guide site. Sources hidden behind collapsed citations were not counted. 4 of the 40 answers showed no sources.
- Age: each website’s domain registration date from public registry (RDAP) records. “Past 12 months” means registered on or after October 5, 2025. Two domains could not be checked and are counted as older.
- Brands: 50 independent US direct-to-consumer brands, 10 per category, plus well-known brands tracked separately.
- Limits: AI answers vary between sessions and users, so the Index is a snapshot, not a ranking.
FAQ
Where does ChatGPT get its holiday gift advice?
In our test, ChatGPT cited 66 different websites across 40 gift questions. The largest group was independent review and gift-guide sites (42%), followed by established publications (32%). Brands’ own websites were 20% of the sources.
Does ChatGPT recommend small brands?
Sometimes. 20 of the 50 independent brands we tracked were named at least once, but 30 were never recommended in their own category.
Why don’t brand websites get cited more?
AI answers to gift questions lean on third-party pages that compare several products. A brand’s own site describes one brand, so it is cited less often unless it carries specific, checkable product information.
How can a brand get recommended by ChatGPT for gift questions?
Start by finding which sites AI cites for your category, then make sure those sites and your own pages carry accurate, specific product information. Sourcelift offers a free AI visibility diagnosis that shows this for your brand.
