# Small sellers under platform algorithms

Business growth is a rising keyword across the tracked journals, and small and medium-sized enterprises are a large topic, but only 19 of 431 recent SME papers carry a platform, e-commerce or algorithm keyword. Millions of small firms now depend on marketplace search rankings. What happens to them when the algorithm changes?

## What prompted this

"Business growth" grew across all journals (25 papers in July–September 2026 against 15 expected) and in management (see the [trends page](/trends)). Since October 2025, 431 papers carry an SME or small-business keyword (157 in management journals, 121 in economics, 117 in finance); only 19 of them carry a platform, e-commerce, algorithm or marketplace keyword, and "platform dependence" appears on 3.

## Questions

- When a marketplace changes its ranking or fee rules, how much do small sellers' sales move, and do they leave or adapt?
- Are sellers that sell through several channels more resilient?
- Do rules such as the EU's Digital Markets Act change how platforms treat small sellers?

## Data that could help

Seller-level sales and rankings from marketplace data providers, announced changes to algorithms and fees, and SME surveys.

## Next step

Collect announced ranking or fee changes on one large marketplace and track the sales ranks of a panel of small sellers around them.
