In a bid to find a good indicator of a great facebook page I have been looking at the 'talking about this' (TAT) number and not just the number of likes a page has.
However, a better indicator is to look at the 'Likes to TAT' percentage.
To do this simply divide the number of people 'talking about this' by the number of 'Likes' you have, then times by 100
So for example if your page has 10,000 likes and 5,000 people talking about this.
5,000/10,000 = 0.5 x 100 = 50
Like to TAT percentage is 50%
Anything above 25% is pretty good.
What is your Like to TAT percentage?
