Earlier this week Google announced on Twitter its “Broad core algorithm update” on Monday. Google also mentions that it “routinely” does updates “throughout the year” which may answer some questions for sites who have experienced gains or drops. However, this does not necessarily mean pages that have dropped have something wrong with the page, it’s just how Google changed their algorithm regulations. So, if your page is not being rewarded, Google still encourages you to continue working on improving your overall site quality. Hopefully, your website will be deservedly rewarded.
Here is Google’s statement towards the 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.
