SEMrush

Hi everyone, I'm 45 years old and have recently transitioned into the SEO field after working in a call center. Due to health issues, I had to leave my previous job, and I’ve been unemployed for the past three years. Recently, I’ve joined a company where I'm tasked with SEO, but I’m completely new to this field and don’t have much knowledge about it. My company uses SEMrush, but I’m struggling to get a solid understanding of how it works. I’ve tried to check out some tips and tutorials, but I’m still finding it difficult to grasp the basics. Could anyone recommend some great tutorials or resources for beginners to understand SEO and SEMrush? Also, I’d love any advice on how to choose the best topics for blogs and conduct keyword research effectively. Any help would be really appreciated! Thank you in advance.
