If you are really serious with blogging and you may even have a publication plan, you should check regularly your stats in WordPress.
Some indicators will appear like Views or Unique Visitors.
If you want to see the stats for one day, just select it and data will update. You will see further down the Referrers (sites that point towards your blog), as well as a nice map showing where your Views and Visitors, or your Likes were done for the selected day.
Hope this serves you and there is more to it here…
