A trusted-looking letter grade sold alongside paid accreditation and paid ad placement; BBB now says plainly that dues don't buy a rating, but it still won't publish how the grade is calculated.

What it's really for A business-reputation rater funded largely by the accreditation dues of the businesses it grades.

What our grade covers The grade on this page is about its A+ to F business letter grades and accreditation seal, 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

The businesses BBB rates are the ones who pay it, and BBB now states that directly: "Dues paid by Accredited Businesses fund our work, which is how we keep our information free for you." It denies the money reaches the grade - "Accreditation dues do not buy a rating, and they do not remove a complaint" - and its accreditation standards run the other way, requiring an applicant to "Maintain at least a B rating." Businesses can also buy labelled ad placements above BBB's own directory results, which BBB says "don't influence BBB ratings, reviews, or Business Profiles." Historically, a 2010 ABC News 20/20 investigation reported that a $425 payment obtained A-minus/A-plus grades for fabricated entities while non-paying firms received F grades; BBB removed accreditation status as a rating factor after that episode.

What it costs you
Free to read The reviews are free to read.
How they make money
A nonprofit federation of local bureaus funded, by its own account, by annual accreditation dues paid by the businesses it rates - fees scaled to company size - plus advertising sold on BBB.org itself.
What they do
It publishes business profiles with A+ to F letter-grade ratings, posts and mediates consumer complaints, and sells a paid "BBB Accredited Business" seal.
What to watch for
A high BBB grade does not mean a business is independently vetted as good; by BBB's own description it is built from complaint history, complaint responsiveness, transparency about practices, and government action. BBB does not publish the formula or the weights: the link it labels "See how we calculate ratings" leads to a page that describes the rating in general terms and does not show the calculation. On a business profile the paid accreditation seal and the letter grade sit side by side with no mention that accreditation costs money.

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 2 / 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.
