Google confirms 'broad core algorithm update'

[Janusri]

Google posted on Twitter that Google does these types of updates “several times per year” and there is nothing a site can do specifically to “fix” their ranking after the core update runs. “Some sites may note drops or gains,” Google explained and said if a page drops, it doesn’t necessarily mean there is something wrong with that page, it is just how Google changed their ranking models that now benefits “pages that were previously under-rewarded.”
