Microsoft Bing is testing loading more people also ask options as you click on them. This is something Google has done for a long time now. But now when you click on an option under the people also ask section within Bing, Bing may load more beneath them - to show you more options. Plus, they load these cards for the site it is referencing. I spotted this via both Sachin Patel and Khushal Bherwani on X - and I was able to replicate it.
Google is testing using inline, hover-style links for citations in the AI Mode results. When you hover your mouse cursor over the link card, it will hover the link card sources over the answer. Google did tell us they are testing new ways to encourage clicks in AI Mode, so maybe this is one of them. This change was spotted by Brodie Clark at SERP Alert who posted a video of this on X, here is a screenshot from his video:
Google is testing having the citations stick to the top (of the AI Overview section only) as you scroll down past the AI Overview. This keeps those citations more in view, as you scroll over the AI Overview. This was first spotted by SERPAlerts on X who wrote, "Google is testing out a sticky citations format on desktop for AI overviews, making it so the first citation stays with the user on scroll. Normally, AI overview citations remain stationary and will be scrolled out of view."
