When you search something related to hotels in Google, you find listed Hotels that are highly standard and affiliated by some reputed third-party organizations including the eco-certified badge.
Include Ticket booking links in search results can be an effective way to boost sales with competitive price ranges. So an eco-certified badge-enabled hotel listing may build up trust among searchers and make a difference from other non-eco-friendly badge hotel listing in search results.
If you are a hotel owner with an eco-certification badge and want to share more information with travelers then you need to log in at your google my business account and add attributes: energy efficiency, 3rd party certification details, water conservation, waste reduction, into the listing.
