How to Increase the Semrush traffic? And shoule SEOer focus on the data?

My site was established in October 2024, I began to do optimization at the beginning of this year, keep updating the blog, optimize the on-page content, until March, the traffic of SEMrush are maintaining the trend of growth, and even in the 3/23 to reach a peak, until March after Google algorithm update, from the 23rd, the traffic of semrush has been falling! I feel very anxious, and I'm wondering if I should be concerned about this data?
