Health information & provider directory

WebMD

Internet Brands (owned by KKR)

Directory / lead-gen Free to read Visit WebMD ↗

Trusted health publisher with a genuinely walled-off editorial side, but its "find a doctor" directory openly sells top placement, so the rankings aren't merit-based.

What it's really for A health-information site with a provider finder; ad-supported, mostly by pharma.

What our grade covers The grade on this page is about its doctor directory and patient ratings, not everything the site does.

Medium Scoring Confidence Mostly sourced, but a detail or two still needs a primary source, so the grade could shift slightly.

Follow the money

Pharmaceutical and consumer-health advertisers pay WebMD the most (about 70% of ad revenue is biopharma), and for the doctor directory, providers can buy placement that pins them atop search results.

What it costs you
Free to read The reviews are free to read.
How they make money
Primarily ad-supported, drawing roughly 70% of ad revenue from biopharma, plus sponsored/native content and paid "Featured Profiles" in its doctor directory.
What they do
WebMD publishes physician-reviewed health content and runs a provider directory where patients search and rate doctors by specialty and location.
What to watch for
By WebMD's own description, doctors who buy a "Featured Profile" are "pinned to the top of all search results," so a directory's top listings reflect who paid, not who ranked best.

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.
