Public competitive baseline
eBay is making the shortlist. AI still isn’t consistently giving buyers a reason to prefer it.
That is not a visibility problem. It is a preference problem.

Choosing the "best" eCommerce marketplace provider depends on various factors, including your business needs, target audience, budget, and specific features you require. Here are some of the most popular eCommerce marketplace providers, each with its strengths:
1. **Shopify**:
- **Pros**: User-friendly, extensive app ecosystem, customizable themes, great for small to medium-sized businesses.
- **Cons**: Transaction fees unless using Shopify Payments, limited built-in features compared to some competitors.
2. **Amazon**:
- **Pros**: Massive customer base, trusted platform, fulfillment services (FBA), various selling options.
- **Cons**: High competition, fees can add up, less control over branding.
3. **eBay**:
- **Pros**: Established marketplace, auction-style listings, global reach.
- **Cons**: Fees can be complex, less control over the customer experience.
4. **WooCommerce**:
- **Pros**: Highly customizable, integrates with WordPress, no monthly fees (but hosting costs apply).
- **Cons**: Requires more technical knowledge, can become complex with many plugins.
5. **BigCommerce**:
- **Pros**: Scalable, built-in features for SEO and multi-channel selling, no transaction fees.
- **Cons**: Can be more complex to set up than Shopify, pricing can be higher for larger businesses.
6. **Etsy**:
- **Pros**: Great for handmade and vintage items, built-in audience, easy to set up.
- **Cons**: Limited to specific types of products, fees can be high for sellers.
7. **Wix eCommerce**:
- **Pros**: User-friendly, drag-and-drop interface, good for small businesses.

8. **Magento (Adobe Commerce)**:

9. **Squarespace**:
- **Pros**: Beautiful design templates, easy to use, good for small businesses and creatives.

When selecting a provider, consider factors such as ease of use, scalability, fees, payment options, customer support, and the specific features that align with your business goals. It's often beneficial to try out a few platforms through free trials or demos to see which one fits your needs best.

Your platform measures the outcome.
We work on what produces it.
You already know where you stand. What
measurement does not show is what the answer was assembled from.
Measure
- Visibility
- Mentions
- Competitor position
- Trends
What we work on
- Which facts about you an assistant can find
- Whether they come from a source it will use
- Where your own version is missing from the answer
- How that changes across the questions that matter
What decides the answer
Nobody tells an assistant which sources to trust. It decides that
on every single answer — and the only thing you control is what it finds
about you when it looks.
What it reads
Third-party write-ups, retailer pages, forums, review sites —
10 of the 10 answers we recorded were built this way.
What it doesn’t
Your own published facts. Across this baseline, an official
eBay source was cited 0 times.
What that means
The version of eBay a buyer hears is assembled from other
people’s descriptions of you, not from yours.
This is the part your monitoring platform reports on but does not
reach. We work on the layer underneath it: which facts about eBay are
available to an assistant, in what form, from a source it will actually use.
What you actually get
Not a report and not a dashboard of scores. A maintained layer of
facts about eBay that an assistant can find, plus the record of what
it does with them.

So: software, not a report. The record you see on this page
is the starting point. What you run afterwards is a maintained fact layer for
eBay and continuous monitoring of what assistants do with it.
456 / 1,501
company domains we scanned already publish a machine-readable
fact layer or explicit rules for AI systems
Measuring and managing are two different jobs
Measuring tells you the score. It does
not change what the score is calculated from. Both matter — and only one
of them is something you can act on.
eBay names 7 AI crawlers in its robots.txt (GPTBot, OAI-SearchBot, ClaudeBot) and publishes no fact layer of its own. Everything an assistant says about you today, it assembled without you.
What your team takes into a budget review
01
The answers themselves
Quotable, each with its date and the assistant that
produced it.
02
The source gap
6 answers describe eBay;
0 of them cite eBay.
03
Where the brand stops moving
Mentioned 6 → recommended
2 → preferred 6.
04
What is actually controllable
Which facts about eBay an assistant can reach,
and which it cannot.
Every line above traces back to a recorded answer with a
timestamp and a provider — which is what holds up in a review, unlike a
score whose method nobody can see.
The uncomfortable part
You already have the
score. If a competitor keeps winning the same commercial questions:
- Do you know why?
- Can you change one thing without changing everything else?
- Can you prove that it moved the outcome?
- Can you repeat it?
If the answer is no, that is a reporting system, not a
growth system.
Fix what assistants say about you
Every prompt, every answer in full, every source behind it, broken down by
assistant. It is a record about eBay, so we release it to a
verified ebay.com address rather than publishing it.
Fix this →
The record stays with your team. Keep Profound, Scrunch, Peec, Semrush or
whatever you use now — this works on the layer underneath what they
measure, and does not replace them.
Who sees this record
Released to a verified ebay.com address only. Not
indexed, not published, not shared with third parties.
Built for regulated work
We already run this method for FDA- and FCC-regulated
manufacturers, where a claim about a product has to survive scrutiny.
Every claim is traceable
Each statement links to the answer it came from, with the
provider and the timestamp. Nothing here is a modelled estimate.

Every answer is reproduced as the assistant returned it at the time shown,
with the classification shown next to the answer it came from — so your
team can check it line by line, and quote it where a number without a method
would not hold up. Each answer carries the assistant, the date and the
sources it drew on, so a business case can be built on the record rather
than on an estimate.
