Advertising disclosure

The rule that matters

Organic rankings on this site are never sold. The order of the live board and any measured comparison is produced by the published methodology from sampled data, and no firm can pay to change it. If a placement is paid or sponsored, it is always labeled as such where it appears.

A firm may be featured by the editors. Featuring is an editorial choice, it is labelled wherever it appears, and it never moves a firm up a ranking or changes a figure.

How we may earn

Revenue, where it exists, can come from:

• Affiliate or partner links and discount codes: if you sign up with a firm through them, the firm may pay us a commission at no extra cost to you. The codes on the discounts page are examples until each one is confirmed with its firm, and each says so.
• Clearly labeled sponsored placements, which never affect measured rankings.

What commissions never touch

Commissions never change a firm's measured spread, its estimated cost, its rank on the board, or its PS Score. A firm that pays nothing is measured and displayed identically to one that pays. Where a specific relationship exists with a listed firm, it is disclosed on the relevant page.

Questions about a specific placement go to Not yet known: legal contact to be confirmed.
