## What this niche is

This niche brings together SaaS tools built for e-commerce sellers. They cover marketplace management, including product research, listing optimization and inventory sync, as well as ad intelligence, from competitor ad spying to campaign analysis.

The users are sellers working across marketplaces and running advertising campaigns, served by tools split between those two specialisations. The group also holds a set of unrelated B2B SaaS platforms addressing other industries.

## How to read these figures

Dozens of sites sit here, spread fairly evenly across the middle and upper ranges: similar shares fall in the three bands from a few thousand monthly visits up to the band below the top, together accounting for most of the niche. Small sites and those above a million visits are each a thin slice. About a third of the sites grew last month.

## About these figures

Megido is a curated corpus of websites with observed revenue: their visitors were observed paying for their products. The sites are grouped into niches by what they do, and niches into wider groups. Each site is a project.

- **Projects**: how many sites a niche or group holds.
- **Growing last month**: the share of its sites whose visits grew by more than 10% on the month before; the others changed less or fell.
- **Leading country**: the country that is the main source of visitors for more of its sites than any other country. It does not say what share of all visitors come from there.
- **Monthly visits**: the share of its sites in each band of average visits a month over twelve months.

Every figure counts the sites firmly inside a niche, not those at its edge, and is a band, not an exact count.

## Ask your agent

- How many marketplace management tools in e-commerce seller tools rely on organic search rather than direct traffic?
- Where do visitors to the ad intelligence and competitor ad spying tools come from outside the United States?
- Can you list the unrelated B2B SaaS platforms in this group and the industries they serve?

Your agent gets the rest from Megido: how the sites moved last month, where their visitors come from, and the sites themselves with their scale, growth and descriptions, and a site's domain once you reveal it.
