Semrush Overview

What I like best about SEMrush is its comprehensive and user-friendly local SEO listing tool. This tool simplifies the management of local business listings across various online directories and platforms, making it a breeze to ensure consistent and accurate business information across the web. With SEMrush's local SEO listing tool, you can easily update and monitor your business listings, improving your local search visibility and ultimately helping potential customers find your business with ease. It's a valuable feature for anyone looking to enhance their online presence and drive more local traffic to their website or physical location. Review collected by and hosted on G2.com.

We use SEMRush on the Search team, and it's most useful while developing the initial target keyword list to use for SEO and even paid search. The Top Organic Keywords tool is the one I use most frequently, and it is a great way to see what's working and what isn't.
Some places in the platform, SEMRush uses their own jargon and they don't fully explain what it means—for example on the Anchor Types widget of the Backlink Audit, it shows a chart of how many links are "Money, Compound, Naked, Empty, etc." It explains Money, but none of the other ones. The Keyword Magic tool is good, but it's still quite a literal tool—it would be a lot to ask, but I wish the tool was able to be more like the semantic search that Google uses now (e.g. synonyms, rather than just phrases including the word you input). I'm not so sure about the Traffic Insights—I always find that the traffic figures are drastically different from what I see in GA. It seems like it does more harm than good to even have such estimates available.
