Lot of Search Engine Experts are claiming that Google has updated its Panda and Penguin algorithms between 23rd and 25th of June.
Search Experts came to this conclusion after observing the SERP ( Search Engine Ranking Position) variation of my websites.
Althout its too early to find what exactly has changed in the algorithm, many suggest its about content quality and internal linking.
Googles Muller has given a hint on the update in below tweet.
Yep! We make updates all the time.
