The search giant is A/B testing black links for its search results. This means that your search experience may be unchanged, as some users are seeing traditional blue links, while others are a part of the trial and see black links.

This change applies to both read and unread links, so users won’t be able to look for the purple link to revisit a page that they previously found useful, but forgot to take note of.

"We're always running many small-scale experiments with the design of the results page," a Google spokesperson told Mashable. "We're not quite sure that black is the new blue."

This isn’t the first time that it’s experimented with how it displays search results. In 2014, Google trialled shades of blue to see which shade people were more likely to click on.
