Top gigs in banner ad category - sales drop?

[designglow]

Hi, Is there any seller who’s having best selling gigs in banner ad category? Can you please let me know you experience these days?
My gig is on the 1st two rows in banner ad category top rated gigs. Since about two three weeks I experience a huge drop of sales. Saw that the search algorithm is updated by the fiverr. Is that the reason? Anyone having same issues?

Thanks
