Ecosia is a Bing-powered search engine that puts 100% of its advertising profits toward climate action, primarily tree planting, and states it does not build personal profiles or sell user data. Its biggest limitation is that its search results mirror Bing’s index rather than an independent one.
How Ecosia Actually Works
Ecosia doesn’t run its own web crawler. Its results are powered by Bing, meaning the accuracy, freshness, and diversity of results generally track Microsoft’s index rather than an independently built one. What Ecosia adds on top is its business model and privacy layer: revenue from search ads (delivered through Google AdSense and Microsoft Advertising) funds tree-planting projects, with the company reporting over 200 million trees planted and publishing monthly financial reports for transparency.
Privacy Practices
Ecosia states it does not create personal profiles or sell user data to advertisers, anonymizes search data within roughly a week, and encrypts all traffic via HTTPS. Advertising is described as minimal and non-intrusive compared to more aggressive ad-funded competitors.

Pros
- Familiar, Bing-quality result set — a low-disruption switch from mainstream search
- Clear, values-driven business model with public financial and environmental reporting
- Stated no-profiling, no-data-sale policy with encrypted traffic
- Lightweight, fast, uncluttered interface
Cons
- Dependent entirely on Bing’s index, so it can’t outperform Bing on raw result quality
- Weaker for niche, highly localized, or non-English searches
- Privacy rests on Ecosia’s own retention practices rather than an independently verified audit
Who Should Use Ecosia
Ecosia suits users who want search results close to mainstream quality (since it’s Bing under the hood) combined with a business model they’re comfortable supporting, and who are satisfied with the company’s own privacy statements rather than requiring independent verification. If independent infrastructure matters more to you than familiar result quality, compare it against our Qwant review or SearXNG review.
Frequently Asked Questions
Does Ecosia use its own search index?
No. Ecosia’s results are powered by Bing’s index rather than an independently built one, which means result quality and coverage generally track Microsoft’s search engine.
How does Ecosia make money?
Through search advertising delivered via Google AdSense and Microsoft Advertising. Ecosia states it puts 100% of its resulting profits toward climate action, primarily tree planting, and publishes monthly financial reports.
Does Ecosia sell my search data?
Ecosia states it does not create personal profiles or sell user data to advertisers, and that search data is anonymized within about a week. This is based on the company’s own published statements rather than an independent third-party audit.
Is Ecosia good for searches outside English or in a specific local area?
It tends to be weaker here than for general English-language queries, since it depends on Bing’s underlying index and coverage for those regions and languages.
How many trees has Ecosia actually planted?
Ecosia has publicly reported over 200 million trees planted through its funded projects, with details available in its published financial and environmental reports.
