# How do I group my products by brand, category or anything else?

Checked against Nova's code on 2026-11-09

Open **Data Inputs › Product Segmentation** and click **New filter**. A filter is one way to group your catalogue (Category, Supplier); its tags are the groups inside it (Kitchen, Garden). Tag your products, and every analytics page can filter by them.

## Who can edit segmentation?

Admins and Workspace owners. A Workspace member sees the page locked, with an **Ask to be Workspace owner** button. See [Roles and permissions](https://intercom.help/nova-analytics/en/articles/17243509-roles-and-permissions-on-nova).

## How do I assign products?

| Way | How |
|---|---|
| One product | Click its cell in the filter's column, pick a tag, or type a new name and click **Create tag "…"** |
| Several products | Tick their checkboxes, then click any tag cell: the change applies to all of them and saves at once |
| Spreadsheet | **Import / Export › Download tags**, edit, then **Upload tags**. A new column creates a filter, tags in one cell are comma-separated, an empty cell removes that SKU's tags in that filter |
| Premade | Switch **Activate** on **Fulfillment Type**, **Hero Products**, **New product launches** or **Price Tier**: Nova tags the catalogue itself |

A filter's column menu has **Rename** and **Delete**; deleting removes all its tags.

## Why does Brand show more brands than I sell?

Nova builds **Brand** itself and refreshes it daily; you cannot edit it.

| You see | Why | Fix |
|---|---|---|
| A brand you do not own | Each tag is the brand on the Amazon product page, which can be the maker of a product you resell | Create your own filter, such as "My brands" |
| Brands of old products | Every SKU still in your listings report counts, inactive ones included, and any SKU sold in the last 90 days | Same |
| Two tags for one brand | Spellings that differ by case, spaces or punctuation merge; different words ("Acme", "Acme Home") do not | Same |
| **No brand** | Nova has not read the product page, it has no brand, or no current listing carries that brand | Nothing to fix |

## How do I filter a page by a tag?

In the filter panel of any analytics page, open **My Filters** and tick the tags. Tags of one filter add up (Kitchen or Garden); tags of different filters narrow each other (Kitchen and Supplier A).

## Can every workspace use the same filter?

An Admin can choose **Show in all workspaces** in a filter's column menu: every workspace then sees the filter and its tags, with its own products only. This cannot be undone. On a shared filter, only Admins rename, delete or add tags; Workspace owners assign products to its tags.

## Can my AI assistant tag products?

Yes, through the Nova MCP connected with OAuth, as a Workspace owner. `list_tags` lists your filters, `get_tags_worksheet` shows each product's tags, and `import_product_tags` writes up to 2,000 rows, saving only after you confirm the preview. See [Connect Claude](/amazon-ai-agents/connect-claude).
