Editorial reviews Free to read Visit Herb.co ↗

Herb.co runs a paid brand-marketing agency alongside its editorial cannabis rankings, and brands pay a fee to be featured. It does disclose this: a sponsorship policy page sets out how paid placement works and what criteria products are picked on, and product sections carry an inline sponsored-content notice. What is still missing is any way to tell which specific item in a guide was paid for.

What it's really for Cannabis lifestyle content and commerce platform targeting millennials and Gen Z; rankings and guides serve as top-of-funnel traffic for brand marketing and product sales.

What our grade covers The grade on this page is about Cannabis strains, consumer cannabis products (edibles, vapes, accessories), and dispensary/delivery service guides primarily for US markets., 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

Herb.co's homepage promotes "Herb Agency" with repeated "Get in Touch" calls-to-action directed at cannabis brands, and the same site produces ranked guides covering those brands. Herb's sponsorship policy states plainly that "Brands pay a fee to be featured on Herb" and that "In some cases, a sponsor may request placement within a specific article or category," while asserting that editorial writes and evaluates independently and sponsors have no editorial control.

What it costs you
Free to read The reviews are free to read.
How they make money
Advertising and sponsored content sold to cannabis brands via Herb Agency; brands pay a fee to be featured in editorial content. Affiliate and tracking links are used on some product placements, and the site runs an on-site product shop.
What they do
Publishes editorial strain guides, product reviews (edibles, vapes, accessories), and city-level "best dispensary" ranked guides. Operates an integrated product shop and runs Herb Agency, a B2B cannabis marketing service that sells sponsored content and advertising to cannabis brands.
What to watch for
Does not publish a scoring rubric, ranking criteria weighting, or named reviewers, and does not label which individual product in a roundup is the paid placement. Its disclosure is a blanket page-level notice that a page contains sponsored content, so a reader can tell that some items were paid for but not which ones. It also confirms sponsors can request placement in a specific article or category.

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 1 / 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.
