Google’s Jon Wiley announced the new design of Google’s search result pages on Google Plus:
“You may have noticed that Google Search on desktop looks a little different today. […]
We’ve increased the size of result titles, removed the underlines, and evened out all the line heights. This improves readability and creates an overall cleaner look. We’ve also brought over our new ad labels from mobile, making the multi-device experience more consistent.”
Here’s a screenshot of the new design:
In this screenshot, most of the result page is made of Google ads that look very similar to regular results. Google might try to get more ad clicks with this change.
