Bing's Citation Share is an official observation of citation space for a grounding query, not a ranking, traffic, or competitor score. Use it to prioritize review work without over-reading the metric.
Google has added a multimodal search-type filter to Search Console. It separates image-led Search demand from text-query reporting; it does not create a new AEO ranking lever.
Google's Preferred Sources button can help an existing reader choose a publication in Search. That is audience participation, not a general AEO ranking control.
OpenAI's Sponsored Agents turn an ad click into a branded conversation. They are not an organic citation, and teams that merge paid and AEO reporting will misread both channels.
A replicable study design for measuring citation rate with defensible error bars. Published as a protocol so results can be compared rather than asserted.
