What does this mean? Google’s mission is to organize all of the information it finds online and present it so that the “best” is at the top of the search results.
How does Google determine what is “best”? Google’s algorithm takes into account so many factors, but one of the most important signals is the number of websites that reference, or link, to the information. Each link is like a vote in that website’s favor telling Google that it deserves to rank high in the search results.
