A page with a lot of backlinks tended to rank higher on all major search engines, including Google. This is still true to a large extent.

Backlinks are links from outside domains that point to pages on your domain; essentially linking back from their domain to yours. To a larger degree, your backlink profile is made up of backlinks from external sites that contribute to the overall strength, relevance and diversity of your domain’s backlink profile.
