Something I have just spotted in the Google results which I have never seen before. On a search for nike the result for the official nike website was showing a plus symbol accompanied by the phrase Stock quote for Nike and one clicking it the result expanded down to show the Google finance result for the Nike sports company.I have never seen this in the search results before and to me it shows a new level of interaction in the SERP. The ability to expand and minimise sections of the page to show and remove certain information. Although there has long been the option to see similar page results this has always been through a new search page and involved having to navigate away from the original results. With the ability to expand down results there would be the option to see the top 10 pages for a website or other similar information without losing your original search. I think we could see further usages of this button in the future.
