A backlink is a link to your website from another website. Backlinks from complementary businesses or industry influencers will not only get your business in front of a larger audience, but it will also drive qualified traffic to your website. In addition, Google picks up on backlinks and will increase its trust in your business if it sees other trusted sites pointing to yours. More trust from Google leads to higher rankings, which leads to more traffic. Get noticed on Google for free with quality backlinks.

In this case, you could automatically generate description meta tags based on each page's content.
