Several SEO tools cover what most small businesses use Semrush for. Ahrefs is known for backlink data, Mangools and SE Ranking suit smaller budgets and beginners, and Moz Pro suits people who like clear explanations.

What each Semrush alternative is known for
Ahrefs
Ahrefs is the name most people mention alongside Semrush. It's best known for its backlink index and a keyword tool that's easy to read. Its free Ahrefs Webmaster Tools gives you site audits and backlink data for sites you can verify. The limit is that the paid plans are built for people doing SEO seriously, so a casual user may not need them.
Moz Pro
Moz is one of the longest-running SEO companies, and it's known for Domain Authority, a score many people use to compare websites. Moz Pro covers keyword research, rank tracking, site crawls and links. Its strength is clear explanations, which suits beginners. Some users find its data less deep than the biggest suites.
SE Ranking
SE Ranking is popular with small businesses and freelancers. Rank tracking and site audits are its strong points, and the interface is friendly. The limit is that there's no free plan, just a trial, so test it with your own site before you commit.
Mangools
Mangools is a small bundle of tools, with KWFinder for keywords as its best-known part. It's simple, tidy and easy to learn. The limit is that it's lighter than the big suites, so it won't replace everything Semrush does.
Ubersuggest
Ubersuggest, from Neil Patel, gives quick keyword ideas, content ideas and a basic site audit. It's handy for business owners who want answers without a learning curve. Its data is less detailed than the bigger tools.
Serpstat
Serpstat packs keyword research, rank tracking, audits and backlink tools into one place. It suits small teams who want a lot of features in one login. The interface can feel busy at first, and plans change, so check what's included.
Similarweb
Similarweb isn't a classic SEO tool. It estimates how much traffic other websites get and where it comes from. That's useful for sizing up competitors. Treat the numbers as estimates, not facts. I've rounded up more free tools to check a competitor's website traffic if that's your main need.
What a small business needs from an SEO tool
Before you pay for anything, think about which of these four jobs you'll do every month. Most small businesses don't need all of them.
- Keyword ideas. Finding the words your customers type into Google. Different tools give different numbers, so I've compared which keyword research tools are most accurate.
- Rank tracking. Watching where your pages sit for the searches that matter to you. Useful once you've got content worth tracking.
- Site audit. Spotting broken links, slow pages, missing titles and other technical problems. A quarterly check is plenty for many small sites.
- Backlinks. Seeing which sites link to you and to your competitors. You can start with my guide on how to check your website's backlinks for free.
If you only need one or two of these, a lighter tool like Mangools or SE Ranking, or a mix of free tools, may be all you need. If you need all four plus competitor research, a bigger suite such as Ahrefs or Moz Pro makes more sense.
A simple way to decide: pick the two jobs that matter most to you, then run a free trial or free lookups on two tools side by side for the same handful of keywords and your own website. Look at which one you understand without a tutorial, and which one gives you a clear next step. The tool you'll open every week beats the one with the longest feature list.

The free-tools route
If you're just starting, I'd begin here. These tools come straight from the search engines, so the data is about your own site, not an estimate.
Google Search Console
Search Console shows which searches bring people to your site, how often your pages appear, which pages are indexed, and any problems Google has found. It's free, and every website owner should have it set up. It doesn't show competitor data.
Bing Webmaster Tools
Bing Webmaster Tools gives you similar data for Bing, plus its own site scan and keyword research. It's free too, and you can import your sites from Google Search Console to save time. Bing's results also feed other services, so it's worth a few minutes of your time.
Put those two together with a free keyword tool and you've got a solid base before you pay for any software. When you start wanting competitor insight or regular tracking, that's the time to try a paid tool.
