Do you know what your Facebook post average impressions (views) are? On average it is 10%.
If your Facebook page has 1,000 fans, only 100 of “your” fans are seeing your posts unless you create REALLY engaging posts. This is due to the Facebook algorithm change made when boosting was introduced. This is where Facebook started requiring money to reach “your” fans.
Your event post on Vero Vine will earn you a minumum of 20,000 views a month on the calendar. The weekly email will earn you over 500 views a week.
Unless you are spending money boosting to audiences on Facebook and/or Google you will never reach the audience you can reach on Vero Vine. A single event submissions earns you thousands of views for Free. You would have to post to Facebook 10 times, make 10 posts for your event and still you would receive less event impressions.
