An interesting development has taken place within Google’s structural framework, and it comes in the form of a core ranking algorithm update. This information was confirmed earlier on in the year by two Google experts, John Mueller and Gary Illyes, who tweeted about the change not being a ‘Penguin update’, but rather a change to the existing algorithm.
It was surprising when Google confirmed this information, since it generally avoids publicizing algorithm updates, and rolls them out without any special announcements. However the importance of this algorithm cannot be underestimated in any way. Webmasters and SEO experts are continually monitoring websites for ranking changes, as well as the inner dynamics of the latest search engine updates.
