Search Engine Optimization (SEO) professionals have been in speculation mode over the last few days about an alleged algorithmic update that has seen some websites lose visibility on Google.
The latest alleged update(s) follows the “broad core” algorithmic update confirmed by Google’s Search Liaison, Danny Sullivan, in April. According to Sullivan that update took place on the 16th April, and followed another core algorithmic update that took place on 7th March.
Google also quietly confirmed another broad core algorithmic update that seemed to be limited to “how to” websites and took place at the beginning of May. Brands like HubPages reported a 22% decline in traffic as a consequence of that update.
According to CNBC, other websites affected include WikiHow, Answers.com and eHow.
In the thread below his announcement in April, Sullivan also drew a distinction between Google’s daily updates and its broad core algorithmic updates, stating the latter take place “several times per year”.
In relation to the “broad core algorithmic” updates, the Google Search Liaison account on Twitter stated on 12th March, “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”.
In response to the speculation around the latest alleged update, Barry Schwartz of Search Engine Roundtable pulled data from a range of competitive analysis tools and discovered very little had changed on a broad scale.
Meanwhile, webmasters have reported a variety of outcomes from significant losses in visibility to minor gains.
