Which of these is NOT a way search has changed in the last 5 years?

Fewer Google algorithm changes is indeed the correct response because, over the past five years, Google has frequently updated its algorithms to improve search results and enhance user experience. These updates often focus on rewarding high-quality content, improving the relevance of search results, and adapting to changing user behaviors, such as the increase in mobile searches and the rise of voice search technology.

The other options highlight key trends that reflect the evolution of search over recent years. For instance, the increased focus on mobile optimization responds to the significant rise in users accessing the internet via mobile devices. The greater emphasis on content quality signifies Google's continual push to ensure users receive valuable and relevant information. Lastly, the rise of voice search technology has transformed how people approach searching online, leading to changes in SEO practices and keyword strategies. Thus, while algorithm changes continue to be frequent and pivotal, the assertion that there have been fewer changes in the last five years does not align with the observable trends in search engine optimization and search technology.
