Results – shows how many clicks you’ve gained. Try to compare it with last week’s clicks. Are they increasing or decreasing?
Cost – shows how much per click cost.
Reach– shows how many users came across your content. Did you meet your target reach?
Spent Today – shows how much you spent today? Is it beyond your budget?
Total Spent – shows the total spent on your campaign. Did you spend enough on that campaign?
