Cheap rank tracking from USD 3 a month, and the two meters that decide whether it is cheap for your list

The cheapest paid rank tracking we could read a published figure for on 29 October 2026 is Keyword.com's entry tier, printed as "Search Visibility $3 /month" with "Annually: $36" beside it and "$4 /month" for monthly billing, sold in packages of 50, 100, 200 and 500 keywords and marked "Google SERP tracking only". The second cheapest is a different shape entirely. SERPRobot states on its pricing page that "Each paid SERP Bot costs $4.99 USD per month and gives you 75 keyword updates per 24 hours", so you are buying a daily check quota rather than a keyword list.

Those two sentences contain the whole decision at this end of the market. Cheap trackers are metered on two different things, the size of your keyword list and how often each keyword is checked, and a tool that is cheap on one of them is usually expensive on the other. Google Keyword Planner reports 10 searches a month in Singapore for this group of phrasings, read against geo 2702 on 26 October 2026, which is a small, specific set of people trying to spend as little as possible on one job.

What five vendors published on 29 October 2026

Two readings on that table need stating plainly rather than leaving in a cell. Wincher's pricing page returned HTTP 200 and a full document, and the price positions in it are filled by the page's own script, so no figure was in the response we read. Its limits were in the document, which is why the row is not empty. SerpWatch returned HTTP 403 on the same date, so there is no SerpWatch figure here at all. Neither of those is evidence about what either company charges, only about what the server returned on 29 October 2026.

The arithmetic that makes these comparable

A reading is one keyword checked once. Convert every price into readings and the shopping stops being a feature comparison.

• Keyword.com entry. $3 a month on the annual commitment for a 50 keyword package is six cents per keyword per month.
• SERPRobot. One bot at $4.99 covers 75 updates every 24 hours, which is about 2,280 updates a month. Spend them on 75 keywords checked daily and that is about 6.7 cents per keyword per month. Spend them on 500 keywords checked weekly, which is roughly 115 updates a day, and one bot still covers it at about a cent per keyword.
• Nightwatch Starter. EUR 79 for 500 keywords tracked daily is about 16 cents per keyword per month, and it includes 50 AI prompts in the same figure.
• AccuRanker Professional. EUR 224 for 2,000 keywords is about 11 cents per keyword per month, falling as you move up the keyword options inside the tier.

Read that way, the cheap end is cheap because it checks less often, watches fewer keywords, or both. The frequency setting moves the same list by a large multiple, so set it first. Five hundred keywords checked daily is about 15,000 readings a month and the same list checked weekly is about 2,150, which is why a weekly list on a cheap tier beats a daily list on an expensive one for most small sites.

The Singapore setting that decides whether any of this is useful here

A rank tracker is only worth three dollars if it can be told to check from Singapore. Positions differ by country and by device, and a default United States reading tells a Singapore business almost nothing about what its own customers see.

Of the pages read on 29 October 2026, Nightwatch states the location capability on every tier in the plan itself, printing "Tracked daily, in any location or language" against the keyword allowance including the Starter plan. Wincher's comparison table carries a "Geo location" row with a check against all three tiers and a local rank tracker section showing "Locations unlimited" with "Included credits 25" and an add on of "Extra credits" at EUR 10 per 500. Keyword.com's cheapest tier is marked "Google SERP tracking only", with the AI side arriving on the tier above, published at "$26 /month" annually or "$33 /month" monthly for 1,000 keywords and 15 credits.

So the check to run before paying anything is to set the location to Singapore inside the trial and compare three positions against what you see yourself in an incognito window. If the tool cannot be set to Singapore at the tier you are buying, its price is not the relevant fact about it.

The tax line, which one of these vendors prints and the others do not

SERPRobot puts it on the pricing page itself. The page states that "Due to the way tax is charged on digital services you may have to pay an additional sales tax depending on your country of residence". That is an unusually honest line for a cheap tool, and it applies to every tool on this page whether or not the vendor mentions it. None of the five offers Singapore dollars, so a Singapore buyer pays the published figure, plus the 9 per cent goods and services tax arriving by one of two routes depending on registration, plus a card conversion charge. On a three dollar subscription that is loose change. On a Nightwatch or AccuRanker annual commitment it is a real line, and our page on what SEO tools really cost a Singapore buyer works through both routes.

Start with the free reading you already own

Before buying any of these, open Google Search Console. It is free, has no keyword cap, and reports average position for queries real people used to reach your own site, which is a different and better object than a position sampled from a data centre. A paid tracker earns its fee by watching keywords you do not yet rank for and by watching competitors, neither of which Search Console does, and the vendors differ sharply on how many rivals they will let you track, which our page on rank tracker alternatives for competitor rank tracking sets out vendor by vendor. Our comparison of free rank tracking software and the published limit on each free tier sets out what the no cost options actually cap.

Buying one, in the order that saves money

• Write the keyword list you will genuinely look at. Most small Singapore sites land between 50 and 300.
• Choose weekly or daily before choosing a vendor. This single setting moves the bill more than the vendor choice does.
• Set Singapore as the location in the trial and verify three positions by hand.
• Check whether a second person needs a login, because seats are priced separately on most of this market.
• Pay monthly for the first two months even where annual is cheaper, then commit once the list has stopped changing.

Questions buyers ask about cheap rank trackers

What is the cheapest rank tracker with a published price

Keyword.com's entry tier at $3 a month billed annually, read on 29 October 2026, for a package starting at 50 keywords and marked Google SERP tracking only.

Why could you not publish a price for two of these tools

Wincher served its plan limits but not its figures, because the numbers are injected by the page's own script. SerpWatch returned HTTP 403. Both are statements about what the servers returned on one date and about nothing else.

Is a cheap tracker accurate for Singapore positions

Accuracy at this end of the market is mostly a question of configuration rather than of data. Set the country, the language and the device explicitly, then verify three positions by hand in the trial, and you will know within an afternoon.

Should I pay per keyword or per check

Pay per keyword if your list is stable and you want daily movement on all of it. Pay per check, which is the SERPRobot shape, if your list is long but you only need a weekly reading, because the quota then stretches much further.

Do any of these track AI answers as well as Google

Nightwatch includes 50 AI prompts in its Starter figure, and Keyword.com puts its AI visibility credits on the tier above the entry one. Treat prompt tracking as a second meter with its own allowance rather than as a feature that comes free with the keywords.

Is an annual commitment worth it at these prices

At three to five dollars a month the saving is trivial and the flexibility is worth more. At the Nightwatch and AccuRanker end the annual discount is real money, so take it only after the keyword list has settled.

The position number that does not exist

Every tool on this page answers one question. Where does a page sit in a list of blue links. Ask a Singapore buyer how they chose their last supplier and a growing share of them describe an answer with no list in it at all, three or four names and a short reason attached to each. There is no position to track there, only whether the name appeared and which pages produced it. AI Knows Us reads that answer, which is a different instrument from everything priced above.
