Semrush is best for all-in-one seo & competitive research.
There's a free trial, so test it on a real project before you commit.
Different tools suit different teams. Here’s where Semrush fits best.
One login covers SEO, PPC, social media scheduling, and content marketing. Your SEO team, paid ads team, and content team can all work in the same platform without paying for three separate tools. The bundled pricing works out cheaper than buying individual point solutions.
The competitive product listing ads research and PLA intelligence show you exactly what your competitors are advertising and which products they're pushing. Combined with keyword gap analysis, you can build an entire product SEO strategy from one dashboard.
The Topic Research tool generates content ideas from a single keyword, showing related questions, trending subtopics, and headline suggestions. It's a research assistant that saves you from staring at a blank document wondering what to write about next.
How it went
I ran a full site audit on a 500-page domain, set up position tracking for 200 keywords across three UK locations, analysed competitor keyword overlap for five domains in the SEO tools space, and used the Content Marketing Platform to plan a content calendar. All testing was on the Pro plan. The interface has a lot of menus and submenus, it took a few sessions before navigating felt natural, but once you know where things are, the workflow is fast.
If you're doing client SEO, yes, one retained client covers the subscription several times over. If you're a solo site owner doing occasional keyword research, the Pro plan is overkill. Start with the free account (limited but useful for basic keyword and domain research) or try SE Ranking at $55/mo. Semrush makes sense when you're regularly checking competitor positions, running scheduled site audits, and tracking keyword movements across multiple projects, not for once-a-month lookups.
The free account lets you do 10 keyword searches per day, run a domain overview, and see limited backlink data. It's enough to test the interface and decide if the workflow suits you. The 7-day free trial on the Pro plan gives you full access, but it does require a credit card. If you forget to cancel, you're on the hook for $139.95, so set a reminder.
They've converged a lot in the last few years. Both now do keywords, backlinks, site audits, and rank tracking well. The deciding factors: Semrush includes PPC, social media, and content marketing tools that Ahrefs doesn't have. Ahrefs has a better backlink database and a cleaner, faster interface. I use both at TheToolist, Semrush for competitive keyword research and content planning, Ahrefs for backlink analysis. If you can only afford one, pick based on whether PPC and social data matter to your work.
If you bill clients for SEO, buy Semrush. One retained account covers the $139.95 several times over, and nothing else matches the PPC, social and content toolkit in a single login. If you're a solo owner doing the odd keyword check, the free account or SE Ranking gets you there cheaper.
