Another few weeks left for the Big Daddy process to come to an end. With just 1-2 data centers left in the switchover process, this software upgradation of Google infrastructure will take a back seat after a while. So, just stay calm even if you get stuck in the Big Daddy's network. For a detailed study on Big Daddy updating procedure you can also visit Searchengine Watch blog. The change has been brought about to bring in enhancements in the core search quality of Google for future months. The new improved functionality would include smarter redirect handling, improved canonicalization and so forth. However, if you think all this is done with just a blink of an eye, you are mistaken. The personnels at Google have worked hard for the almost done Big Daddy status. Hats off to them!
But, it was stated that Big Daddy also went "Supplemental" with most of the websites suffering because either they got stuck in the process or their search results varied. Quite a distressful thing it might have been. Enormous flow of these "supplemental results" listed in the index were a major concern for Google. "Perhaps the problem is almost resolved," said Matt Cutts in his latest review over the Big Daddy issue. Hope So!
So, for the ones who really peeped into the deep history of the "gonesupplemental" thing should take a sigh of relief because if not all of it, atleast some bit of it has been improved. However, Matt Cutt also stated that more pages would be indexed in the coming few weeks. HOWZDAT! Google still has an official help page on it, but it was always very confusing.
You don't have to worry if your site doesn't see any kind of improvements, this would probably be because of the fact that you might have to wait for Google's crawl cycle to complete its turn.
