Microsoft Bing is running a favicon size test that, if it holds, will make the top sponsored result visually heavier than every other listing on the page. The favicon displayed in the top paid slot measures roughly 33% larger than the icons shown on organic results or lower-placed ads, according to Search Engine Roundtable.
The test was first spotted by Khushal Bherwani, who shared a screenshot on X. Search Engine Roundtable’s Barry Schwartz confirmed he could replicate the behavior independently, with the enlarged icon appearing exclusively on the top sponsored position and not cascading to secondary ads or organic listings.
This is a test, not a confirmed rollout. No timeline or broader availability has been announced by Microsoft Bing.
For paid search teams, the practical read is narrow but real: a larger brand icon in the top ad slot is a visual-hierarchy signal that could nudge click-through rates upward for whichever advertiser holds that position. The mechanism is attention, not relevance. Brands bidding aggressively for the top slot on Bing would want to audit their favicon quality now, since a low-resolution or generic icon would be more exposed at larger display sizes than at the current default.
