The tech giant's Chrome web browser will be able to warn users - by using a clear badge - about certain sites that typically load slowly, and the company could even choose to take the user's device and current network conditions into consideration.
In a blog post, Google said: "We think the web can do better and want to help users understand when a site may load slowly, while rewarding sites delivering fast experiences.
"In the future, Chrome may identify sites that typically load fast or slow for users with clear badging. This may take a number of forms and we plan to experiment with different options, to determine which provides the most value to our users.
"Badging is intended to identify when sites are authored in a way that makes them slow generally, looking at historical load latencies. Further along, we may expand this to include identifying when a page is likely to be slow for a user based on their device and network conditions."
Meanwhile, the company noted the plan would be a "gradual" process as they look to enhance user experience.
The post continued: "Our plan to identify sites that are fast or slow will take place in gradual steps, based on increasingly stringent criteria.
"Our long-term goal is to define badging for high-quality experiences, which may include signals beyond just speed."
