Abrupt increase in Impression but no clicks

[fayazx]

So, I am a level 1 seller on Fiverr. I recently made a new gig and have been promoting it since. Despite the promotion, the impressions and clicks were not as much as I had expected to be. The clicks were quite healthy compared to the impressions,like more than 6%. Then I revamped the keywords a bit and its been few days the impressions have increased abruptly but the clicks have not. Is there a glitch or something else? Please help me understand whats going on. Thanks in Advance.
