SEMRush allows me to have a second opinion when it comes to SEO tools and techniques. It also provides a valuable keyword analysis tool. Additionally, it allows me to build links for local SEO which has been a huge help with local SEO link-building and monitoring. It allows me to monitor my back links in-depth to ensure that I don't have spammy or poor links connecting to my site, and to search for the best place to create new local links.
Another feature of Ahrefs that could potentially help you take your campaign to even better heights is their content gap feature. It gives you the option to check which keywords your competitors are ranking for so you can stay one step ahead at all times. Basically speaking, Ahrefs gives SEOs the ability to overtake their competitors through knowing which keywords to target and focus on.
