## Range gaps are argued from opinion, not from rivals' catalogs

Category reviews and NPD pipelines need one answer: where does the market sell that we don't, and where are we already stronger? It is usually assembled from a few site visits and a sales deck, so the strongest voice wins and adjacent categories get missed because nobody counted them.

Counting by hand does not survive a competitor with 1,500 products, and naming differs by brand, so 'gift set', 'coffret' and 'kit' never line up in a spreadsheet. A gap that comes from a label rather than the range sends a development brief the wrong way.

- In a published RivalSweeper sample of a fragrance house (163 products) vs 3 rivals, the house had 0% coverage in makeup & nails against a rival average of 20.3%; all 3 rivals sold it, led by one at 31.2% (149 products). (source: https://www.rivalsweeper.com/use-cases/competitive-gap-analysis)
- The same read found a strength: gift sets & kits coverage of 26.4% for the house vs a 1.3% rival average. (source: https://www.rivalsweeper.com/use-cases/competitive-gap-analysis)
- It also flagged a scale threat: one rival listed 1,491 distinct products, 9.1x the house's 163. (source: https://www.rivalsweeper.com/use-cases/competitive-gap-analysis)

## How it works

1. **Add your store and the set.** Add your own domain and the rivals you compete with for the same customer: 2 on Basic, 15 on Pro.
2. **Catalogs mapped to categories.** Your range and each rival's are read from public storefronts and grouped into the same categories, so coverage compares like with like.
3. **Gaps scored, claims checked.** Each category gets your coverage, the rival average and how many rivals carry it. Claims are re-checked against real product titles before publishing.
4. **Weekly SWOT read.** Strengths, weaknesses, threats and opportunities in plain sentences, refreshed weekly as rivals add and drop lines.

## Features

- **Coverage vs the whole set.** Your share in each category beside the rival average, for example perfume 41.1% vs 23.7%.
- **Whitespace scored.** A category none of your range covers is ranked by how many rivals sell it. '3 of 3 rivals' is a stronger signal than one outlier.
- **Leading rival per gap.** Who leads a category you lack and how deep they go, for example 31.2% of their range, 149 products.
- **Strengths to defend.** Categories where you over-index the set, so the review protects what already sets you apart.
- **Range scale comparison.** Distinct products you list against each rival, so breadth threats are stated in numbers.
- **Checked against product titles.** Every claim is re-checked against real product titles before publishing, so a gap is not an artefact of a label.
- **Weekly refresh.** Coverage and the SWOT read are refreshed weekly as rivals change their range.

## Who it's for

- **Category managers.** You own category roles and the range review. You get coverage vs the set and scored whitespace to argue a category in or out with numbers.
- **Product development and NPD leads.** You decide which line extensions get briefed. You see adjacent categories every rival already sells, and how deep the leader goes.
- **Heads of buying and merchandising.** You balance breadth against depth. You see where rivals outscale you and where your range already over-indexes.

## Compared with the alternatives

- **Site visits and a spreadsheet.** Free and fine for one rival. Category naming differs by brand, counts drift, and nobody refreshes it until the next review.
- **Consultancy range reviews.** Deep and tailored, but a one-off snapshot. RivalSweeper keeps the same comparison running weekly.
- **Enterprise retail analytics suites.** Broad market coverage, typically scoped through a sales process. RivalSweeper reads your named rivals' own storefronts, monthly.

## FAQ

### Does this show what rivals actually sell through?

No. It reads public storefronts, so coverage is what each rival lists, not sales volume. Pair it with your own sales data.

### Is every whitespace category an opportunity?

No. '3 of 3 rivals sell it' shows the category exists in your set, not that it fits your brand or margin. It is the prompt for a business case.

### How do you avoid false gaps from naming?

Every claim in the read is re-checked against real product titles before it is published.

### How often is it refreshed?

Weekly. Catalog changes themselves surface within 48 hours, and new arrivals are often seen before rivals promote them.

### How many rivals should I include?

The brands your customer would compare you with. Basic covers 2 plus your store; Pro covers 15; extra domains are $10 a month.

### What do I need to provide?

Only domains. Nothing is installed and no store or analytics account is connected.
