In March 2024, my websites impressions dropped to 0 and now they are back again

2 years back, I had started working on a website, it was steadily picking steam and I was clocking 100 -200 impressions a day and in March, they suddenly hit 0. I felt helpless and felt that this got hit by the update and now in Dec-Jan, all of a sudden the impressions are back, not sure what to make of this
