Google appears to be testing a new animation effect in Search ads, where an underline is drawn beneath the advertiser’s domain name as if someone were painting it.

The underline gradually appears and then disappears, creating a subtle animated effect that draws attention to the website address displayed below the business name.

This visual change could make sponsored results more noticeable and potentially influence user engagement. It is unclear whether this is a limited test or part of a broader rollout.
