Google changes its search algorithm every year around 500-600 times, most of changes are minor Google occasionally rolls out a “major” algorithmic update (such as Google Panda and Google Penguin) that affects search results in significant ways. Google confirmed on Wednesday 13 March 2019, that it released a broad core search ranking algorithm update this week.
Official Google SearchLiaison twitter handle announced that Google would like to call the broad core algorithm update of March 12th as “March 2019 Core Update.” If your rankings did change recently, it may have been related to this broad core ranking update and not necessarily related to a technical change you made on your website.
There are many reasons why a website may lose traffic and rankings after Google rolls out an algorithm update. In most cases, the SEO strategies that the website used to rank in SERP backfires, and in other instances, Google finds a better site that provides superior quality content as a replacement.
“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.
