Google is an amazing and powerful took that can help you find information. But have you ever thought about how Google always seems to know exactly what you're looking for, even when you're not sure yourself?
Google considers many factors when they are finding your results. Some of the factors Google considers include:
Google will rank your results for you based on these factors and give you the information that Google thinks you want. Google uses a complex series of programs called algorithms which analyze your previous activity in Google to figure out which sources to show you first.
If you always read or click on the same types of articles with the same subjects or viewpoints, Google is going to rank these results higher than others. This can make it difficult to find sources from other places/viewpoints that you don't normally read or click on. You can learn more about this topic, called Filter Bubbles, by checking out this video: Beware Online "Filter Bubbles" (TED talk).
