Google has maintained a dominant market share in search engines of over 67% through continuous innovation and improvement of its core search algorithm. It has diversified its revenue streams beyond advertising through acquisitions and development of products like Gmail, Android, YouTube, and cloud computing services. Google pursues both a differentiation strategy through its data centers and search technology and a growth strategy of M&As, partnerships, and rapid adoption of new technologies. It faces opportunities from trends like increased internet access and mobile usage globally but also threats from competition and potential over-reliance on secrecy and advertising revenue.
