Google has confirmed that a major core algorithm update was released last week. Such an update occurs many times in a year which might bring one or more changes to search results. Google didn’t specify as to what changes had been implemented since it could be anything from changes aimed at specific enhancements, to broad changes which can affect all search results.
Sights can witness or improve as a result of the changes which have occurred which Google says is normal. It sounds as though rankings can fluctuate according to the way pages should be ranking before this update. In case your rankings drop after this update, Google states that there is no particular “fix” other than to keep “building great content”.
Here is Google’s statement on Twitter:-
Each day, Google usually releases one or more changes designed to improve our results. Some are focused around specific improvements. Some are broad changes. Last week, we released a broad core algorithm update. We do these routinely several times per year.

Sites can see drops or gains in rankings because of the changes which occurred which according to Google is normal. It sounds as if rankings will fluctuate according to how pages should have been ranking before this update.
There’s nothing wrong with pages that may now perform less well. Instead, it’s that changes to our systems are benefiting pages that were previously under-rewarded.
There’s no “fix” for pages which can perform less well other than to stay focused on creating high-quality content. Over a time period, it can be that your content might rise relative to other pages.
