Currently, I've been utilizing both SEMrush and Ahrefs for optimizing my friend's website (https://surahwaqia.com/). These tools have proven to be invaluable in enhancing the site's SEO performance, providing comprehensive keyword research, backlink analysis, and competitor insights. I highly recommend giving them a try as they offer a powerful combination of features to boost online visibility and drive organic traffic.
using only one tool will limit in my opinion using multiple tools will enhance the outreach and the score of website like for my own website: stafftimerapp.com like ahrefs, semrush , moz.com , google keyword planner ,wordstream
