On Twitter, Google published a post saying that it released a “broad core algorithm update” this past Monday. According to Google, it “routinely” updates “thoughout the year” and referenced communication from the previous core update.
Google’s core search updates happen “several times per year.” Although “some sites may note drops or gains,” there is nothing specific a site can do to tweak its ranking around these updates. It’s Google’s hope that, to continue to improve your overall site quality, and when Google runs these updates again, hopefully, your website will be rewarded.
In an explanation by Google, “pages that were previously under-rewarded” would see a benefit from these core updates.
The following is a statement that Google made previously about this type of update:
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.
As with any update, some sites may note drops or gains. 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 that may perform less well, other than to remain focused on building great content. Over time, it may be that your content may rise relative to other pages.
On Monday, we released a broad core algorithm update, as we routinely do throughout the year. For background and advice about these, see our tweet from last month: https://t.co/uPlEdSu6xp
