YouTube is the world's second-largest search engine after Google. This means businesses have a prime opportunity to ensure their content is discoverable to billions, just by optimizing their video descriptions, titles, and tags.

Just like Google's search engine, Youtube also tries to find the most relevant results according to keyword queries. Videos are “ranked” based on a variety of factors like how well the title, description, and the content matches the viewer's query.

YouTube makes search predictions based on factors like popularity or similarity. When you choose a prediction, you'll find results for what you just chose.
