Semrush, Ahrefs, SE Ranking, Moz Pro and Surfer SEO for a small business: the job each one does, checked prices, the free SEO tools to use first, and which one fits your situation.
A small business rarely needs the most powerful SEO tool. It needs one that answers its actual questions — what should we write about, why does this page not rank, are we moving up — at a price that survives a quiet quarter. The five tools in this guide cover the realistic range: three full platforms in Semrush, Ahrefs and SE Ranking, the approachable Moz Pro, and one specialist, Surfer SEO, which does content optimisation and little else.
Every price below was checked against the vendor's own pricing page on 10 September 2026 and is the rate the vendor lists for its plan. Most of these vendors discount annual billing, and prices change, so check the plan you need before you buy.
Small-business SEO usually comes down to four jobs.
Keyword research tells you what people search for and how hard it will be to rank. Every suite here does it; Ahrefs' Keywords Explorer also covers YouTube, Amazon and Bing as well as Google.
Site audits crawl your site for technical problems: broken links, missing titles, pages search engines cannot reach. SE Ranking's entry plan includes an audit allowance of 250,000 pages a month, far more than a small site will use.
Rank tracking shows whether the work is paying off. SE Ranking includes daily rank checks on every plan, and Semrush's Position Tracking supports daily updates by location and device.
Content optimisation guides what to put on a page you are writing. It is Surfer SEO's entire job, and the suites cover it more lightly.
If you mostly publish content and rarely look at competitors or links, you may not need a suite at all. If you run a local business with a handful of pages, the free options below may be enough for the first year.
| Tool | Entry paid plan | Free option | Free trial | Best for |
|---|---|---|---|---|
| Ahrefs | Starter, $29 a month | Ahrefs Free, for sites you verify | No | Backlink data and keyword research |
| Surfer SEO | Discovery, $49 a month | No | No | Writing and optimising content |
| Moz Pro | Standard, $99 a month | No | 30 days | Marketers new to SEO |
| SE Ranking | Core, $129 a month | No | 14 days | Rank tracking and client reports |
| Semrush | SEO, $139 a month | Free account with daily limits | 7 days | Breadth: SEO, paid search and content |
The entry prices above buy very different amounts. Ahrefs Starter is the cheapest way into a suite, but its credit-based limits run out quickly, and the Ahrefs plan usually weighed against the other suites is Lite at $129 a month. Moz Pro Standard is $99 for one user, three tracked sites and 300 tracked keywords, with Medium at $179 and Large at $299. SE Ranking Core is $129 and Growth $279. The Semrush SEO plan is $139, and Starter is $199.
Seats matter more than small businesses expect. Every Semrush plan includes a single user, Moz Pro Standard includes one, SE Ranking Core includes one manager seat where Growth includes three, and Ahrefs charges for additional users on most plans. If two people will log in, price two seats before you compare.
Add-ons change the real cost as well. SE Ranking's white-label reporting and API access are paid add-ons that need annual billing; Semrush sells several capabilities as separate toolkits; and Surfer SEO sells its AI Search Analytics plan separately, at $82 a month.
Before paying for anything, use what is free.
Free tools rarely do competitor research at volume or consistent rank tracking over time. When you find yourself wanting those, that is the point to pay. Moz Pro, SE Ranking and Surfer SEO have no free plan; Moz Pro's 30-day trial and SE Ranking's 14-day trial are the ways to try the first two.
You write content and want it to rank. Start with Surfer SEO if you already know what to write about: its Content Editor gives writers an on-page brief inside Google Docs and WordPress. Pair it with Search Console rather than a suite until you need competitor research. Its scores are correlational, so treat them as guidance rather than a target.
You are new to SEO and want one approachable tool. Moz Pro is built for this, with a clear campaign structure, strong learning resources and the longest trial here. Accept keyword and link indexes that are smaller than the market leaders'.
You care most about rankings and reporting, or you are a freelancer or small agency. SE Ranking includes daily rank tracking on every plan and white-label client reporting through its Agency Pack. It is no longer a budget option, so choose it for the tracking and reporting rather than the price.
You want the best data on backlinks and keywords. Choose Ahrefs. Starter works when budget is tight, as long as you know its credit limits are tight too, and there is no free trial, so try the interface on Ahrefs Free first.
You run SEO, paid search and content marketing together. Semrush covers the most ground of any tool here. For one person doing occasional SEO it is more than you need; for a small marketing team that uses the breadth, it can stand in for several separate tools.

Shortlist two tools, use the free tier or trial of each on your own site for a week, and keep the one you actually opened. If you would rather have a ranking against your own needs, describe your situation in the Finder.
