A timeline is a chronological presentation of a list of events that take place over time. You can share content, photos, and videos on your timeline for all of your followers to see. You can also create events or pin important posts to the top of your page so people don’t forget about them. It also provides an overview of what you’ve been up to recently. It does more than just post about your brand. Your timeline is essentially your life on social media laid out in an informative and interesting way.
