Alphabet's Google proposed further changes to the way its search results work in Europe to satisfy requests from competitors and regulators.
Under the European Union's Digital Markets Act, Google said it had to make substantial changes to the services it can provide in the continent, including redesigning certain features and removing others to ensure its own services aren't favored over competitors.
The company made several changes to Google Search to boost the prominence of comparison sites in categories like flights, hotels and shopping.
While many of these changes benefited large online travel aggregators and comparison sites, certain airlines, hotel operators and small retailers are losing traffic and struggling to reach customers, with some reporting a 30% drop in direct booking clicks, it said.
To try and mitigate this, Google said it is proposing further changes that will allow users to choose between results that take them to comparison sites and results that take them directly to supplier websites when they are searching for products, restaurants, flights or hotels.
In addition, it will offer new formats that allow comparison sites and suppliers to show more information about what is on their websites, like prices and pictures, as well as new ad units for comparison sites.
"We think the latest proposal is the right way to balance the difficult trade-offs that the DMA involves," Google's legal director, Oliver Bethell, said in a statement Tuesday.
In Germany, Belgium and Estonia, Google also plans to remove a mapping feature that shows where hotels are with results underneath it as part of a short test to understand how the change would impact both the user experience and traffic to websites.
"We're very reluctant to take this step, as removing helpful features does not benefit consumers or businesses in Europe," Bethell said.
