For anyone who wants to hear a legitimate oddity in Google, rather than a bunch of garbage about an algorithm change, or some 'strange happenings': I own a few eCommerce sites. On 2 of them I drastically modified my page Title a little over a week ago. Within a few days, Google noted the change and update both sites. Each day I have checked my sites, and have seen the same titles, until today. Google reverted both sites (in 2 different niches) back to my old, previous Titles. The sites are unchanged. The cache updated for each on April 11 (at different times). I'm sure they will change back to the new titles soon, but just thought I'd mention it. p.s. I also think Google is doing something recently, but I won't dare speculate that they are making some algorithm update or rankings change, etc. Just something.
