Google’s Gary Illyes has confirmed that Google started rolling out Panda update version 4.2 last weekend, affecting 2–3% of queries.
Google algorithm updates always rouse a storm on the internet community as they directly affect website rankings. The latest such refresh is Google Panda 4.2, which began on 18th July, 2015. However, the rollout is extremely slow and that’s the reason people didn’t notice it. According to Google, it may take months till the time we are able to notice any significant impact on the website rankings. It might also not affect all the pages of a website in the short run. Google officials were tight-lipped about why the rollout is so slow.
