Research · Market Intelligence

How crowded is the market — measured, not felt.

Market Intelligence compares every indexed niche on five signals of competition: the queue of offers, the pressure of paid placements, the review strength of the head, how much the top sellers hold — and the one score that combines them.

  • Low, medium, high — every niche sorted into a band with the same thresholds.
  • Five signals behind the score, each is shown on its own so you see what makes a niche hard.
  • Crowded markets and open ones on one screen, across all 10,217 niches.
  • The same scale everywhere — percentiles of the whole index, not of the department.

Why you need it

“Why is my niche so hard — and where is it easier?”

Without it

  • Competition looks the same everywhere: many offers, many reviews, ads on top.
  • You cannot tell whether the hard part is the head’s reviews, the paid shelf or five sellers holding the market.
  • Choosing a category by gut means entering the crowded one by default.

With Market Intelligence

  • Every niche is in a band — low, medium, high — with the same thresholds.
  • The signals apart: ad share of the shelf, ad pressure at the top, reviews needed for the top ten, top-5 share.
  • Open markets above the revenue you need on one screen.

Ad spend goes where shelf space is bought

In a niche where the top of the listing is ×13 more paid than the rest, an organic newcomer pays for every impression. Market Intelligence shows that before the campaign — and points to the niches where the shelf is still organic and a good title is enough.

How it works

Three steps, the whole product

1

Pick a band

Low, medium or high competition. Each band lists the niches inside it with their revenue, so a low-competition band is not a list of empty markets but a list of markets with room in them.

  • Switch bands with one control
  • Each band sorted by revenue
  • Department and path shown in full

2

Compare the signals

The score is one number, but the reasons differ. A niche can be hard because the head has ten thousand reviews, or because a third of the shelf is paid, or because five sellers hold most of it. The table shows each signal on its own.

  • Offer density — how long the queue is for a product
  • Advertising pressure — the share of sponsored cards
  • Review strength and top-5 concentration

3

Open the niche

The same niche detail as in Category Insights: the products, the sellers who hold them, the price bands. Read who you would be up against before deciding that you are.

  • Sellers ranked inside the niche
  • Top products with buyers and reviews
  • Price bands with revenue and units

What is inside

Built from what Allegro actually shows

Every figure on the screen has the page it was taken from and the method printed next to it. These are the parts.

Competition index

The average of three percentiles — offer queue, review strength, paid shelf — with the same 40/60 thresholds in every niche. One number, one meaning, across the product.

Offer density

How many offers compete on a product card, based on the cards in the listing. A long queue means a buy box to fight for.

Advertising pressure

The share of sponsored cards on the niche's listing. Marzi measures it per card: the average is 16%, but niches range far around it.

Review strength

How many reviews the niche leader has accumulated — the moat a newcomer has to cross.

Concentration

The share of revenue the top five sellers hold. A fragmented market and a captured one can have the same size and very different odds.

Bands across the tree

Every niche in the index is placed in a band, so a search for “low competition, above 1M zł” is a filter, not a research project.

What the numbers mean

Measured, estimated, and not yet

Marzi says which is which on the screen itself. Here is the short version for Market Intelligence.

Measured

Offers, sponsored cards, reviews are read from the listing on every weekly pass.
Concentration is computed from the revenue the index measures per seller.
Bands use fixed thresholds — a niche does not move bands because its neighbours did.

Estimated or limited

The score is relative: a percentile across the whole index, so it means “harder than most of Allegro”, not “impossible”.
Advertising is measured on the listing's first pages, where it concentrates — deeper pages carry less.
Movement between bands needs history; until checks are 21 days apart, the table shows only the current band.
Who it's for

Three ways to use Market Intelligence

Starting out

Filter the index down to the niches where the head is beatable — then check that the revenue is worth the trouble.

Already selling

See why your niche feels harder this year: more paid placements, a longer queue, or a head that pulled away.

Brands and agencies

Map a department by competition to decide where a new line has room and where it will pay for every impression.

FAQ

questions about Market Intelligence

What is the competition score?

The average of three percentiles across the whole index: the length of the queue of offers on a product, the review strength of the niche's head, and the share of paid placements on the listing. Below 40 is low, 40–60 medium, above 60 high.

Why percentiles and not raw numbers?

So that the score means the same thing everywhere. Two hundred reviews is a lot in a small niche and nothing in smartphones; a percentile of the whole index puts both on one scale.

How is advertising pressure measured?

Card by card on the listing: which cards carry the sponsored label, across all cards read. The index-wide average is 16%; the table shows each niche's own share.

What does concentration mean?

The share of the niche's revenue held by its top five sellers. It is computed from the same per-seller revenue the index measures, and it separates a market that is merely big from one that is already taken.

Can I see who the sellers are?

Yes — open the niche and the sellers are ranked inside it, with their revenue and product count. Seller identities are part of the paid layer.

Does the band change every week?

The thresholds are fixed, so a band changes only when the niche's own signals move. History between passes switches on once they are at least 21 days apart.
