Ranking placement is openly for sale via per-click bidding. Treat order with suspicion.

What it's really for A software directory and lead-gen channel. The running order is closer to an ad auction than a recommendation.

What our grade covers The grade on this page is about its software directory rankings and category placement, not everything the site does.

High Scoring Confidence Checked against primary sources. We are confident in the facts and the grade here.

Follow the money

Vendors bid per click for placement, so the running order is shaped directly by who pays the most to appear high.

How the grade was reached

Independence · 30% weight 1 / 5

Does the site take money from the very entities it ranks? Pay-for-placement, vendor-funded data, and affiliate commissions all pull this down. The less the ranking can be bought, the higher the score.

Evidence basis · 30% weight 2 / 5

What is the ranking actually built on? Hands-on testing scores highest, then verified first-hand reviews, then opinion or popularity surveys and self-reported figures, then pay-to-rank, which scores lowest.

Method transparency · 20% weight 2 / 5

Is the methodology published, specific, and reproducible? Can a reader see how a given rank was reached, or is it a black box?

Conflict disclosure · 10% weight 3 / 5

Are commercial relationships, sponsorships, and affiliate arrangements disclosed clearly and near the rankings themselves, rather than buried?

Manipulation resistance · 10% weight 3 / 5

How hard is it to game? Controls against fake reviews, solicited reviews, and vendor gaming raise this; an open box anyone can stuff lowers it.
