SGE continues to evolve. I'm now seeing what I'm calling "SGE lite" in the SERPs. SGE doesn't trigger a large block by default anymore... it's now much smaller with a large "Show more" button.
Again, IMO SGE will not roll out unless it's revenue-neutral or positive... There is no way they are going to lose billions of dollars in ad revenue by adding SGE (esp. since Bing Chat has yielded NO increase in market share at all). Stay tuned:
