Please add timer elements. They help reinforce one of the most important marketing tactics: urgency.

There are two times of timers you should look at:

1)times that naturally end

Ex. You pick a date that's 3 dates out and the time counts down till then, and everyone will see the same timer ticking down.

So you could do this for the end of a sale

2)Evergreen timers

So these are timers that are unique to everyone

For the evergreen timers please make them persistant, so basically the timer doesn't reset everytime the page is refreshed.

Ex. You have a welcome discount for 10% off that expires in 12 hours. When someone signs up for this discount then all see that specific timer start a countdown for 12 hours that helps give them that sense of urgency.

Also if they close the site and come back to it later they should see the timer counting down as if they never left (ex they close site with 12 hours left on timer. Then comeback after 4 hours, the timer should say there is 8 hours left. It SHOULD NOT referesh the timer back to 12 hours)
