WordPress and
Shopify articles post themselves →We took one seed term, emergency plumber, and ran it through six keyword tools to see what each actually gives a small business, on the free tier and on the paid one. The best long tail keyword tools for small business owners are not the ones with the biggest databases. They are the ones that surface specific, answerable questions without demanding a subscription you will use twice a year.
Here is the short version, then the detail on each tool below.
The best long-tail keyword tools for small business, compared
| Tool | Free tier | Paid from (approx, at time of writing) | Best for |
|---|---|---|---|
| Google Search Console | Fully free | Free | Queries your site already gets |
| Google Keyword Planner | Free with an Ads account | Free (exact volumes need ad spend) | Head terms and rough demand |
| AnswerThePublic | A small number of daily searches | Under £10 a month | Question phrases |
| Ubersuggest | Three searches a day | Around £29 a month, lifetime deals common | All-rounder on a budget |
| KWFinder (Mangools) | A handful of lookups a day | Around £20 a month billed annually | Difficulty scores you can trust |
| LowFruits | A few free credits on signup | About £20 for a credit bundle | Finding weak SERPs you can win |
Prices move around, especially the lifetime deals, so check before you buy. What follows is what each tool actually produced for our seed term.
How we tested them
One seed term, emergency plumber, entered into every tool the same way. We looked at three things: what long-tail phrases each surfaced, what the free tier caps you at, and whether the paid version earns its price for a business that does keyword research a few times a year, not daily.
Google Search Console: the free baseline
Search Console is not a suggestion tool. It shows the queries your site already appears for, which makes it the most honest data you will ever get. For an established plumbing site, the Performance report typically reveals phrases no suggestion tool offers, such as landlord and tenant questions about who pays for a call-out, or town-specific variants you never deliberately targeted.
The catch is obvious: it only works if your site has some history. A new site sees nothing. If you have not set it up, do that first, because everything else in this article is a supplement to it, not a replacement.
Google Keyword Planner: free, broad, and vague
Keyword Planner is free with a Google Ads account and you do not need to run ads to use it. For our seed term it returned the head terms you would expect: 24 hour plumber, emergency plumber near me, plumber prices. Useful for gauging rough demand, poor at questions. It rarely surfaces phrases like whether emergency plumbers charge a call-out fee, which is exactly the sort of long-tail query a small business can win.
Unless you spend on ads, volumes appear as wide ranges rather than numbers. Treat them as big, medium or small and move on.
AnswerThePublic: the question machine
AnswerThePublic mines Google's autocomplete and arranges the results as questions, prepositions and comparisons. Our seed term produced the richest question list of any tool tested: how much an emergency plumber costs in the UK, whether one can fix a boiler, whether they charge a call-out fee, what counts as a plumbing emergency.
The free tier limits you to a small number of searches a day, which is genuinely enough for occasional use. Paid plans start under £10 a month at the time of writing. It gives you no reliable volume data, but for finding the questions real people ask, nothing free comes close.
Ubersuggest: the budget all-rounder
Ubersuggest sits in the middle: keyword suggestions, a difficulty score and a look at who currently ranks. The free tier allows three searches a day, which sounds tight but works if you plan your seeds before you open the tool. For emergency plumber it surfaced cost and no-call-out-charge variants alongside the head terms.
The paid plan is around £29 a month, and a one-off lifetime licence is frequently promoted. If you research keywords once a quarter, the lifetime deal is the only version worth considering. The daily drip of the free tier is fine for everyone else.
KWFinder: the nicest interface, the smallest free tier
KWFinder, part of the Mangools suite, is the most pleasant of these tools to use. Its autocomplete and questions tabs surfaced strong local long-tail variants for our seed, including open-now and near-me phrasings, and its difficulty score is the most trustworthy of the group in our experience.
The free account allows only a handful of lookups a day, which is a taster rather than a working tier. Paid plans start around £20 a month on annual billing. It is a good tool that most small businesses will not use often enough to justify a subscription.
LowFruits: the one that does something different
LowFruits does not just suggest keywords. It scans the actual search results for each phrase and flags the ones where weak pages rank, such as forum threads and thin directory listings. Those are the fights a small site can win. For our seed term it flagged several cost and how-much variants where forums held page one positions.
Pricing is credits rather than a subscription: a starter bundle costs about £20 and new accounts get a small free allowance. For occasional research, that model suits a small business far better than a monthly fee.
Rule of thumb: if you research keywords less than once a month, buy credits, not subscriptions. A £20 bundle of LowFruits credits beats a £29 monthly plan you forget to cancel.
Verdicts by situation
- If you will spend nothing: Search Console for what you already rank for, Keyword Planner for rough demand, and AnswerThePublic's free searches for questions. That combination covers most of what a small business needs.
- If you will pay for one thing: a LowFruits credit bundle. It is the only tool here that tells you which long-tail terms are actually winnable, and the credit model matches how often you will really use it.
- If you want a proper subscription: KWFinder, but only if keyword research is a regular part of your week. For most owners it is not.
No keyword tool knows what your customers asked you on the phone last week. You do.
And there is an honest third answer: many small businesses do not need a tool at all. A local trade with a dozen service pages can get everything it needs from autocomplete, the People Also Ask box and its own inbox. We have written up that approach in full in our guide to finding keywords without paid tools. Start there, and buy software only when the free methods stop producing ideas.
Where Helio SEO fits in
Helio SEO does this research as part of the service: it works out which long-tail keywords your business can win and shows the reasoning in a dashboard, then writes the articles to match. If you enjoy running the tools above yourself, you do not need us for the research. If you would rather it simply happened every day without you, that is the job we built it for.
