Fill in the blank: Google recommends that tap targets should be at least ___________ apart from each other.

HubSpot places this check under SEO recommendations for Mobile Experience , where it flags tap targets that are too small or too close together on mobile devices. The guidance is about touch usability, so the goal is to reduce accidental taps and make links and buttons easier to activate on smaller screens. HubSpot also pairs this recommendation with a minimum interactive target size of 48 by 48 pixels, which confirms that the rule is about mobile-friendly interaction design. The correct choice is the minimum spacing value associated with that tap-target guideline. HubSpot+1
