OceanHero is a free search engine service. Like with Google or Bing, the main source of revenue for OceanHero is the money advertisers pay to display their listings above and below the organic listings. This comes at no cost to the user. OceanHero uses a similar Cost-Per-Click structure as other search engines. This means when a user clicks on an ad, the business that placed the advertisement is charged. Unlike Google or Bing, OceanHero has committed to use that money towards environmental projects for cleaning the ocean. There are other sources of revenue for OceanHero including direct funding and donations.
