Social media sharing decrease my gig impression


#1

A greeting to all fiverr user
Hope all of you are doing well
I have been on fiverr since last 5 days
when i created my gig I got 26 impression on 1st night
After sharing it on social media like facebook groups, google plus community and twitter i receive only 13 impression in next 3 days
And next day when I stop sharing I received 69 impression on single day along with 4 orders
Can anyone say what is the algorithm behind this?
