The first time I did it (307 pages), the traffic went up by 12k visits per day.
I thought what I did would have the same effect, because when I've added to the "sub content" on the same pages it has, but for some reason these haven't ever ranked quite where they should based on the level of information they presented with the "summary" at the top, so the only answer I could come up with was to "make them more like the rest" that generally sit in the top 5 for a variety of terms.
The new pages I added a few days ago without the information at the top shot straight into the top 5 as soon as they were indexed and the ones I added a couple weeks ago did the same thing and "stuck" there, so when the key difference in the way the information is presented on some pages is the summary at the top I have to conclude it's the "stopping point" on the rankings for those pages.
I left it for probably way longer than I should have thinking the algo would "get it" and rank the pages where it should over time based on what I know is "quality", but it's been too long to hold on to that idea any more.
I guess the bottom line to me is: when the algo and I disagree on the definition of "quality" or "what visitors want" the algo wins and I have to figure out how to do what it determines is best which is not always what I think or know is best.
Don't know yet, because they're so far behind in getting the index updated they don't even have most of the changes as far as I know.
I should probably add: I don't see any reason why they wouldn't since I have other pages without the information at the top that "just sit" in the top 5 and do their thing, but the "improved ones" with the additional information didn't for some reason.
