Start with the inventory you can actually use. Check your target niche and country, publisher transparency, metrics, order controls, revision handling, and whether the platform exposes enough information for an independent review.
- Exact inventory depth in your niche and geography.
- Visibility into publisher URLs, metrics, requirements and pricing.
- Ability to reject weak opportunities before purchase.
- Content, revision and replacement workflows.
- Enough transparency to run your own quality checks.
Marketplace size is a discovery metric
A large catalog increases the chance that useful sites exist somewhere in the inventory. It does not tell you how many are relevant to your exact niche, country, quality threshold or budget. A smaller catalog with better fit can be more useful than a huge one full of irrelevant options.
Control matters as much as inventory
Buyers should know what is being purchased, what the publisher requires, whether content can be reviewed, what link attributes apply, and what happens if a placement is changed or removed. These workflow details become more important as order volume grows.

A practical decision rule
If an opportunity looks attractive only when you hide the site’s topic, traffic pattern and recent publishing behavior and focus on a single authority score, skip it. Strong opportunities should survive a broader review.
