Affiliate Disclosure
Revenue is allowed. Editorial capture is not.
Some links on Greenhouse Guide are affiliate links, and more may become affiliate links over time. Some premium-brand referrals may earn us a flat fee. Neither changes the standard we apply to the recommendation itself.
What this means in practice
If a page includes an affiliate link, Greenhouse Guide may earn a commission if a reader buys through that link. The price to you does not usually change, but the site may be compensated by the merchant. Every affiliate link on this site carries rel="sponsored" markup, and any page containing them carries a visible disclosure block. If a page has neither, the links on it earn us nothing. Most of the affiliate revenue lives in the mid-market and accessory lane, twin-wall kits, auto vent openers, heaters, staging, because that is where buyers click to buy online.
Premium-brand and installer referrals
For heirloom glasshouses and high-end builds, the sale happens through consultation, not a shopping cart, so we may refer readers to named, vetted premium brands or installers. When we do, the referral fee is flat and disclosed on the page. We never auction leads, we never sell the same lead to five brands, and a brand cannot pay to become “recommended”. A referral is us putting our name next to theirs, which is exactly why it can't be bought.
What this does not mean
A commission does not buy a recommendation, and it never buys a ranking. Some of the biggest greenhouse brands run affiliate programs, some credible ones don't, and our roundups do not care which is which. We do not treat every $15,000 glasshouse as a winner, and we do not treat every $2,000 polycarbonate greenhouse as a compromise. The point of the site is to reduce buyer mistakes, not to maximize checkout rates.
Structural-safety pages carry nothing
Our wind-anchoring, snow-load, glass-safety, and overheating pages carry no affiliate links, no sponsorships, and no email capture. Structural and horticultural-loss guidance is not a sales surface, full stop.
Sponsorships
We may accept sponsorships. A sponsor gets labeled placement, clearly marked as sponsored, and nothing else. Sponsors do not see content before publication, do not move rankings, and do not get their weaknesses removed from our brand records. Manufacturer access improves accuracy, never ranking.
How we keep it clean
We prefer explicit tradeoffs, clear downside sections, and category fit over generic “best overall” language. When a greenhouse yellows early, racks without the optional base, ships with no ventilation, or is mismatched to the likely buyer, that is part of the published verdict, affiliate relationship or not. If you ever spot a recommendation that reads like it was written for the merchant instead of the buyer, email us. That is a bug, and we treat it like one.
