60-second pick: Don’t know what to write? KeySearch or LowFruits. Want one dashboard? Ubersuggest. Just want volume data while browsing? Keywords Everywhere.
Research-based: no hands-on testing is claimed for these tools.
Why $30 is the real budget line
Semrush starts at $139.95 a month. Ahrefs starts at $129 a month. For a small publisher or one-person site, that is $1,500-plus a year before you have written a single article — and most of that dashboard goes unused. If you open your SEO tool once or twice a week to pick keywords, check a ranking, and fix a technical issue, you do not need an agency suite.
$30 a month is the line where the maths changes. Below it, a tool costs less than a takeaway dinner each month, and a full year stays under $360. Every tool here clears that line on its entry plan — verified against official pricing pages in October 2026 — and does at least one SEO job properly. None does everything Semrush or Ahrefs does, and we state that trade-off up front.
How we picked these tools
One hard rule, no exceptions: the tool’s entry plan must cost under $30 a month on the billing term stated. Where a vendor shows two prices — a monthly price and a cheaper annual equivalent — we show both and say which is which, because the number on the pricing page is not always the number that leaves your account in month one. Prices were checked in October 2026 and they change often, so check the vendor’s page before you buy.
Each tool also had to do a real, named job: keyword research, rank tracking, a site audit, or browser-side keyword data. Everything here is research-based: we did not buy or trial these tools for this guide, and we claim no hands-on testing.
For keyword research: KeySearch
KeySearch is the most complete keyword research tool under $30. The Starter plan costs $24 a month billed monthly, or $240 a year (a $20-a-month equivalent). For that you get 200 keyword searches a day, 80 tracked keywords, 2,000 audited pages a month, and a content assistant, plus competitor research, backlink checks, live SERP analysis, and YouTube research.
Best for a blogger or small publisher who needs one tool for finding keywords and judging whether they can rank for them. Its difficulty score, live SERP view, and competitor keyword lists cover the weekly decisions a content site actually makes.
Biggest limit: the rank tracker. Eighty tracked keywords is enough for a small site’s core pages, but it runs out fast if you track every post you publish. The Pro plan lifts it to 200 keywords — but at $48 a month it is over this guide’s $30 line, so it is not the plan we are recommending here.
For finding keywords you can actually win: LowFruits
LowFruits does one job differently from every other tool here: instead of giving you a difficulty score, it reads the live search results and flags the weak spots — forums, low-authority sites, and mismatched pages ranking in the top 10. For a new or low-authority site, that is often more useful than a score, because it shows you which results you can realistically outrank.
The Standard subscription costs $29.90 a month billed monthly, or $249 a year (a $20.75-a-month equivalent). That monthly figure squeaks under this guide’s line by ten cents, so if you pay month to month, this is the tightest fit on the list. Standard includes 3,000 SERP-analysis credits a month, 100 tracked keywords, and the subscription-only features: the Boosted Keyword Finder, rank tracker, Domain Explorer, competitor keyword extraction, and sitemap extraction.
Biggest limit: the credit system. One credit buys one keyword analysis, and subscription credits reset every month — they do not roll over. Analyse in big batches and 3,000 credits goes faster than it sounds. A pay-as-you-go option ($25 for 2,000 credits, valid a year) suits burst research, but it excludes the rank tracker and extraction tools.
For everything in one dashboard: Ubersuggest
Ubersuggest is the only tool on this list that genuinely tries to be an all-in-one: keyword research, site audits, rank tracking, competitor analysis, and backlink data in one dashboard. The Individual plan covers 1 project, 150 reports a day, 125 tracked keywords, 1,000 audit pages a week, and 20,000 keyword suggestions a month.
Pricing needs a careful read. The plans page’s own comparison module quotes the Ubersuggest range as $29 to $99 a month, and Individual is the entry tier — so entry sits under $30 on the list price — with yearly and lifetime options alongside, and a lifetime special offer bannered on the page in October 2026. Prices and promotions change often, and the page can render in different currencies by locale, so check the US-dollar figure before you buy.
Biggest limit: data depth. Its keyword database and backlink index are thinner than Semrush’s or Ahrefs’, and the site audit checks fewer issues. For a single small site that is usually fine. For client work or competitive niches, it is the first place you will feel the ceiling.
For keyword data inside your browser: Keywords Everywhere
Keywords Everywhere is a browser extension, not a dashboard. It shows search volume, CPC, competition, and 12-month trend data directly on Google, YouTube, and other search pages, and it includes a keyword finder, bulk data lookup, and an API on the same credit pool.
The Bronze plan costs $84 a year, billed annually only — there is no monthly billing option. That works out to a $7-a-month equivalent, but you pay the $84 up front, and that distinction matters for a tight budget. Bronze includes 100,000 credits a year and one user seat; one credit buys the volume, CPC, competition, and trend data for one keyword, and credits expire 12 months after purchase.
Biggest limit: it is a data layer, not a workflow. It will not track rankings, audit your site, or analyse competitors. It pairs well with the free stack below, but alone it answers only one question: what is this keyword worth?
Why Mangools is not on this list
Older “cheap SEO tools” articles still list Mangools at $29.90 a month. That figure is out of date: reads of Mangools’ own pricing page dated September–October 2026 put its entry Basic plan at $37.70 a month billed annually ($452.40 a year), or $61 month to month. That is over the $30 line on every billing term, so Mangools fails this guide’s hard rule — even though it is otherwise a good suite. If its price drops back under $30, it belongs here again.
The tools compared
| Tool | Entry price (billing term) | Best for | Biggest limit |
|---|---|---|---|
| KeySearch | $24/mo billed monthly ($240/yr) | All-round keyword research for bloggers | Only 80 tracked keywords on Starter |
| LowFruits | $29.90/mo billed monthly ($249/yr) | Finding weak SERPs a small site can win | Credit budget resets monthly, no rollover |
| Ubersuggest | $29/mo billed monthly (yearly + lifetime options) | One dashboard for keywords, audits, tracking | Thinner data than Semrush or Ahrefs |
| Keywords Everywhere | $84/yr, annual billing only ($7/mo equivalent) | Keyword data inside your browser | No rank tracking, audits, or competitor tools |
A realistic stack is one paid tool plus the free stack below — not all four at once. KeySearch or LowFruits for research, Ubersuggest for one dashboard, Keywords Everywhere if you live in your browser. Add a second paid tool only once your publishing volume outgrows one tool’s limits.
The $0 stack: do this before you pay anything
Before spending a dollar, set up the free tools. They give you data no paid tool can estimate as well, because most of it comes from the search engines themselves.
- Google Search Console (free) — the queries you already appear for, your clicks and positions, which pages Google refuses to index, and Core Web Vitals from real users. If you track nothing else, track this.
- Google Analytics 4 (free) — what visitors do after they arrive, and whether they take a useful action. A ranking means nothing if the traffic does not convert.
- Bing Webmaster Tools (free) — a second opinion on crawling and indexing, and you can import your site from Search Console during setup.
- Ahrefs Free (free, for sites you verify) — site audits and your own backlink profile from the largest link index in the industry, without the $129-a-month subscription. It does not show competitors’ data.
- Screaming Frog SEO Spider (free tier) — a desktop crawler that finds broken links, missing titles, duplicate pages, and redirect chains. The free tier crawls up to 500 URLs, which covers most small sites; a paid licence removes the cap.
For a site under a few hundred pages, this free stack plus one paid research tool covers nearly every weekly SEO decision. The paid tool earns its money once you publish often enough that guessing keywords costs you real traffic.
Frequently asked questions
Can I do SEO completely free?
Yes, for measurement, research, and technical checks: Search Console, Analytics, Bing Webmaster Tools, Ahrefs Free, and the free Screaming Frog crawler cover those jobs at $0. What costs money — or time — is the content and the links. A paid tool saves hours of research; it does not write content or earn you mentions.
Do I need Semrush or Ahrefs?
Not at this stage. Semrush and Ahrefs are built for agencies and in-house SEO teams. If you manage SEO alongside running the site, one tool from this list covers most of what Semrush does at a fifth of the price. Upgrade when your content output or competition justifies deeper data — not before.
Which tool should I buy first?
Buy for your bottleneck. If you do not know what to write about, KeySearch or LowFruits. If you want one dashboard, Ubersuggest. If you already know your keywords and just want volume data while browsing, Keywords Everywhere. Do not buy a suite for features you open once a month.
Is monthly or annual billing better?
Annual billing is cheaper per month on every tool here — KeySearch drops from $24 to a $20 equivalent, LowFruits from $29.90 to $20.75 — but it locks you in for a year. Start monthly for a month or two, and switch to annual only once you open the tool every week.
Why is Mangools missing from this list?
Because its entry price rose past the $30 line. Its Basic plan now reads $37.70 a month billed annually, or $61 month to month, on its pricing page. Older articles quoting $29.90 are out of date. The rule for this guide is a hard ceiling, and Mangools no longer clears it.
Will a cheap tool hurt my rankings?
No. Rankings come from your content, pages, and links — not from which tool measured them. A cheap tool may show slightly different volume or difficulty numbers, but that affects which keywords you choose, not how Google ranks your pages. What hurts rankings is buying bulk backlink packages or publishing thin content.

How we compare
SmartRiseHQ comparisons are research-based. We read the vendor’s own pricing and product pages, compare the published plan limits, and report what each tool does and where it stops. We claim no hands-on testing here, and we accept no payment for placement. Every tool here earned its place by clearing one published rule: an entry plan under $30 a month.
A note on pricing
All prices were checked on the vendors’ official pricing pages in October 2026 and are shown in US dollars. Two cautions. First, vendors change prices and run promotions: Ubersuggest’s pricing varies by billing term, locale, and promotion — its entry tier lists from $29 a month — and LowFruits’ $29.90 monthly figure sits ten cents under this guide’s ceiling. Second, three vendors’ pricing grids render with scripts, so where a live page’s figures did not render as text, we corroborated them against multiple independent reads of the same official page dated September–October 2026. Re-check the vendor’s page before you buy; if any figure here has changed, the live page wins.
