What Keyword Tool costs, and why the price is not where its own homepage sends you

Keyword Tool publishes four Pro plans, and read on keywordtool.io/pro on 29 October 2026 the page opens on its annual rates: Starter at USD 68 a month, Growth at USD 148, Scale at USD 308 and Agency at USD 628, each printed with the word month beside it. Those are the figures you pay on annual billing. Billed monthly, the same four plans are USD 88, USD 188, USD 388 and USD 788 a month. The page is unusually clear about which is which if you read its markup: every price block carries an attribute naming its period, monthly or yearly, and on load only the yearly blocks in US dollars are the ones set to show. The page's own claim of a saving of over 20 per cent holds at every step, and the arithmetic is the proof. 68 against 88 is 22.7 per cent off, 148 against 188 is 21.3, 308 against 388 is 20.6, and 628 against 788 is 20.3.

Google Keyword Planner reports 10 searches a month in Singapore for this group of phrasings, read against geo 2702 for the Singapore plan of 26 October 2026, so this is a small set of buyers comparing one tool against the free one it is sold against. The useful part of the answer is not only the ladder. It is that neither address a buyer tries first carries the price, and one line in the product's own documentation decides whether half of it works for Singapore at all.

The two addresses that do not have the price on them

Three readings, all taken on 29 October 2026 with a desktop browser user agent.

• keywordtool.io/pricing returns HTTP 404. The body is not empty: it is about 38,900 bytes carrying roughly 480 visible words of the site's own styling and navigation. A not found page that renders like a real one is the single easiest thing to mistake for a read, so check the status code rather than whether something appeared.
• The homepage does not link a pricing page. Where it invites you to subscribe, it links keywordtool.io/user/subscribe, and the site's own robots.txt carries the line Disallow /user/. So the route the homepage offers is a path the site asks crawlers to leave alone.
• The ladder is on keywordtool.io/pro, which no Disallow line covers, and the API documentation at keywordtool.io/api names the four plans in text and points there, stating that API access is available on dedicated legacy API plans and the latest Keyword Tool Pro plans, Starter, Growth, Scale and Agency.

None of that is hidden pricing. The figures are published, in two currencies, on a page anything can read. They are simply not on the address people guess and not on the address the homepage hands you, which is why a quick look at this vendor so often ends with somebody concluding the price is behind a sales call.

The published ladder, read on 29 October 2026

Plan	Annual billing, as the page shows it first	Monthly billing	Bulk search volume a day	Trend history
Starter, described as for solo marketers	USD 68 a month	USD 88 a month	50,000 keywords	12 months
Growth, marked Most Popular Plan	USD 148 a month	USD 188 a month	100,000 keywords	24 months
Scale, described as for in house teams	USD 308 a month	USD 388 a month	200,000 keywords	up to 48 months
Agency, described as for teams at scale	USD 628 a month	USD 788 a month	400,000 keywords	up to 48 months

Above Agency the page states that higher limits need a custom quote, so the published ladder stops at 788 and the step after it comes from a conversation. The page also states a 30 day money back guarantee, and that the web interface, the API and MCP access are included in every plan.

Read the period label before you read the number, on this page and on every page like it. An annual rate printed with the word month beside it is the normal way this category displays a ladder, and it is the single most common reason two buyers quote different figures for the same plan. Our page on what AccuRanker costs at every keyword step reads the same display convention on a rank tracker where the markup does not label the period at all, which makes it considerably harder to tell which figure you are looking at.

The currency selector changes the symbol and not the number

The page carries a currency control offering euros, and the body holds 16 price figures, eight in dollars and eight in euros. Each euro figure carries the same digits as its dollar twin: 88 beside 88, 148 beside 148, 628 beside 628, at every step and in both billing periods. For a Singapore buyer paying by card, those are not the same amount of money, because 88 euros and 88 dollars convert to different Singapore dollar figures on any given day. Pick the currency deliberately rather than taking whichever one the page offered, and price the conversion your own bank applies on the billing date rather than a mid market rate you read somewhere else.

What each plan actually meters

The limits read from keywordtool.io/api on 29 October 2026 are specific, and they decide which plan you need more than the feature list does.

• One daily allowance, three channels. The documentation states that daily request limits are shared across the web interface, the API and MCP, and that some older legacy plans count some or all channels separately. If you plan to script against it and use the interface, you are drawing from one bucket.
• A fixed reset, not a rolling window. The limit resets on a 24 hour cycle aligned to the hour your account was created, in your account's timezone if set. For a Singapore team that is worth setting on day one, because an unset timezone puts your reset in somebody else's working day.
• Request sizes. A single suggestion request can return up to about 1,000 keyword ideas, and a volume request can take up to 1,000 keywords. Bulk search volume runs to your plan's daily capacity, which is the 50,000 to 400,000 column above.
• Where the volume comes from. The documentation states Google and Bing search volume is sourced directly from Google Keyword Planner and Bing Keyword Planner, with estimated volume for YouTube, Amazon, Perplexity, eBay, the App Store, Play Store, Instagram, X, Reddit, Pinterest, Etsy, TikTok and Naver based on clickstream data. Two different kinds of number in one column, and worth keeping straight when you report them.

The coverage line that matters most in Singapore

This is the paragraph to read before the price. On localisation, the product states Google coverage of more than 190 countries, 68,000 locations and 50 languages, and separately Bing coverage of 6 countries, 31,000 locations and 3 languages. The API documentation names those six: Australia, Canada, France, Germany, the United Kingdom and the United States. Singapore is not one of them.

So for a Singapore buyer, the Bing half of this product returns suggestions but not the Bing volume, cost per click and competition data that the six named countries get. If your reason for buying is Google long tail discovery, that changes nothing. If your reason was a second independent volume source for this market, the published coverage says the second source does not cover you, and that is a decision you can make before paying rather than after.

What the free route gives you first

There is a real free tier and it is worth exhausting before you compare plans.

• The web tool, with no account. The site states the free version generates up to 750 or more keywords from Google autocomplete in seconds, and that it can display search volume for some keywords. Keyword suggestions themselves come from autocomplete rather than from the ad planner, which is the product's actual argument for existing.
• A guest MCP endpoint. The documentation states no API key and no signup, limited to Google and Bing suggestions with volume and trend on the first five keywords when cached, with cost per click, competition and bid data requiring a Pro plan. Four tools are named, covering suggestions, search volume, competitor analysis and a quota check.
• Google Keyword Planner itself, which is free. It needs a Google Ads account opened in expert mode and no campaign, and with no active spend it reports volumes as ranges rather than single figures. Our page on using Keyword Planner free without running ads sets out the exact steps and the free sources that fill its gaps.

Keyword Tool's own pages argue the case against that free tool directly, stating that Keyword Planner is not broken, that it is built for ad buyers, and that its design aggregates similar terms into broad buckets, applies volume thresholds and surfaces commercial queries with high cost per click. That is a fair description of what an advertising planner does, and it is also the reason the planner is the right instrument for one job and the wrong one for another. Buy the autocomplete source when you need phrasings the planner groups away. Use the planner when you need the figure a planner is authoritative for, which is what we do for the Singapore volumes on this site.

The files written for assistants, and the one number not in them

Something unusual sits in this vendor's robots.txt, read on 29 October 2026. Alongside the Disallow lines it carries a content signal reading search yes, ai input yes and ai train yes, Allow lines for OAuth discovery endpoints and for a model context file under .well-known, and an Agentmap line pointing at keywordtool.io/.well-known/ai-catalog.json. That catalog, fetched the same day, publishes two entries: a Keyword Tool MCP Server with a server card, and an agent skill called Keyword research, each with a list of representative queries such as getting monthly search volume for a thousand keywords in Germany.

So this vendor has gone further than most in telling machines how to use its product. What none of those files carries is a price, and the subscribe path is the one the same robots file asks crawlers to skip. An assistant asked how to pull search volume here has a documented answer. An assistant asked what it costs has to find /pro on its own. That gap is not unique to this vendor. It is the ordinary condition of this category, and it is the reason a buying question and a usage question get answers of very different quality.

What a Singapore buyer settles before paying

Two lines, neither of them the vendor's to answer. The first is tax. IRAS states the current GST rate as 9 per cent and names two routes by which an overseas supply reaches a Singapore buyer, reverse charge when you buy services from overseas suppliers and overseas vendor registration when the supplier is registered to supply customers here. Which one applies depends on your own registration status, and our page on what SEO tools really cost a Singapore buyer sets out both regimes with the IRAS wording. The second is scale. Singapore is one city and the commercial tail here is short, so a 50,000 keyword daily allowance is already larger than most single market Singapore projects use. The plan to buy is decided by how many markets and how many clients you serve, not by the size of the allowance.

Questions buyers ask about Keyword Tool pricing

Why does the figure I saw not match the figure somebody quoted me

Because the page opens on the annual rate with the word month printed beside it. Starter shows 68 a month on annual billing and is 88 a month billed monthly, and the same gap of just over 20 per cent runs up the whole ladder. Check the billing switch before you quote the number to anybody.

Is there a free version

Yes. The web tool runs without an account and the site states it returns 750 or more keywords from Google autocomplete, with volume shown for some keywords. A guest MCP endpoint needs no key and is limited to suggestions with volume and trend on the first five keywords when cached. Cost per click, competition and bid data are stated as requiring a Pro plan.

Does the Bing data cover Singapore

No. The published Bing coverage is six countries, named in the API documentation as Australia, Canada, France, Germany, the United Kingdom and the United States. Google coverage is stated at more than 190 countries, so Singapore Google data is covered and Singapore Bing volume is not.

Which plan does an API or MCP project need

Any of the four Pro plans, or a dedicated legacy API plan, per the vendor's own documentation. The thing to size is the shared daily limit, because the web interface, the API and MCP all draw from the same allowance on current plans.

Can I get a refund if it does not fit

The Pro page states a 30 day money back guarantee. Use those thirty days on the question that actually decides it, which is whether autocomplete sourced phrasings add anything to the list you already get free from the planner and from Search Console.

The question a keyword list cannot answer any more

A keyword tool exists to tell you what people type and how often. That is still the right question for a results page, and it is the wrong shape of question for a conversation: when somebody asks an assistant which supplier to use in a category, there is no query volume behind the answer and no position in it either, just a short list of company names assembled from whatever the assistant read. A long tail list will not tell you whether your name is in that set. AI Knows Us measures which companies get named when buyers ask those questions, and shows the pages each mention was drawn from, so the two sit on either side of one decision rather than competing for it. On the thing this page is about, Keyword Tool wins outright, because we publish no keyword volume of any kind and have no intention of starting.
