In short, reverse image search is the process of finding images using an image as the starting point rather than a written search query. The company added the “Search by Image” feature, which allowed reverse image search. That was one of the reasons why ten years later, in 2011, Google expanded the functionality of Google Images. For instance, a user might want to find a very specific image but couldn’t come up with a term for which Google would return what they wanted. However, that approach was often not sufficient.

For the first ten years since its release, it supported a keyword-based search only, providing images relevant to user queries. Google introduced the Google Images search engine back in 2001.
