KWFinder vs Semrush Keyword Magic Tool: the entry ticket, compared

The short version

If keyword research is the whole job, KWFinder wins on price by a distance: $30.50 a month, or $18.85 prepaid annually, against $139 a month or $117.33 billed annually for the cheapest Semrush plan that includes the Keyword Magic Tool. If keyword research is one task inside a broader SEO job, that comparison is unfair, because the Semrush price buys a platform and the KWFinder price buys a keyword tool.

So the deciding question is not which tool is better. It is whether you will use the other nine things Semrush sells you.

KWFinder vs Semrush Keyword Magic Tool, on price

Mangools' Basic plan is $30.50 a month, dropping to $18.85 a month if you prepay $226.20 for the year, and gives 100 keyword lookups per 24 hours with up to 200 related suggestions each. No extra seats are available on that plan at all.

Semrush's cheapest plan carrying the Keyword Magic Tool is the SEO plan at $139 a month, or $117.33 a month billed annually, which also brings five websites and 500 keywords tracked daily. Semrush's annual toggle advertises a saving of "up to 17%", against the roughly 35% Mangools takes off for the same commitment.

At list prices billed annually that is $226.20 a year against $1,407.96 — a gap of more than six times. Nothing about that gap tells you which tool has better data; it tells you that one product is a keyword tool and the other is a suite.

What each one claims to hold

Semrush advertises that the Keyword Magic Tool draws on "more than 26 billion keywords and growing", reporting volume, difficulty, cost-per-click and intent for each. Mangools advertises "2.5 Billion related keywords" and "~ 65 k supported locations" for KWFinder, reporting volume, difficulty, cost-per-click and a trend.

Both figures are vendors counting their own indexes, and neither was checked here. They are quoted because index size is part of what the price buys, and because the ten-fold difference between the two claims is at least consistent with the price difference. It is not evidence that either number on screen is more likely to be right.

The free tiers work differently

Mangools gives a free account with 5 lookups per 24 hours, 15 related and 5 competitor keywords per lookup — small, but the real interface, every day, forever. Semrush's free account allows one demo project and 10 reports a day across the entire toolkit, which sounds more generous until you notice that every report you open anywhere in Semrush draws on the same ten.

For evaluating a keyword tool specifically, five daily lookups in the real product is arguably the better test. Semrush also offers a seven-day free trial of the paid plans, and Mangools offers a full refund within 48 hours of payment instead.

What the extra money buys, honestly

It is easy to write the suite off at six times the price, and worth being precise about what the gap contains. Semrush's SEO plan at $139 includes five websites and 500 keywords tracked daily alongside the Keyword Magic Tool. Mangools Basic includes 200 tracked keywords updated weekly and no extra seats.

So the difference is not only database depth; it is daily position data, several projects, and a much wider set of reports around the keyword tool. If you are managing one site and checking positions occasionally, none of that is worth $108 a month. If you are checking five sites every morning, the arithmetic reverses quickly.

Where each one is weakest

KWFinder's weakness is headroom. The 100 daily lookups do not bank, no seats are available on Basic, and the only plan with daily rank updates is $70.50. Growth out of it is a plan change rather than an add-on.

Semrush's weakness at this tier is that the free account is a poor way to evaluate it: 10 reports a day across the whole toolkit is spent quickly, and the seven-day trial means committing a week of attention rather than sampling it over a month. Neither weakness is about data quality, which is the thing neither this site nor anyone outside the vendors can judge.

Which one to buy

• You research keywords and write pages. KWFinder, prepaid annually. The rest of a suite is money you will not use.
• You also audit sites, track positions daily across several domains, and report to clients. The suite price stops looking absurd, and this is not really a keyword-tool decision.
• You want the largest index you can afford. That is a different question from either of these, and it points at the big suites generally rather than at their keyword modules.
• You have not spent anything yet. Neither, for now. The free tools and where they stop is the page.

The tie-breaker nobody mentions

If the two are genuinely close for you, pick the one you will open. A keyword tool earns its money through use, and the cheapest subscription you stop logging into is more expensive than the dearest one you use every week.

That is a real argument for KWFinder's single-screen layout and a real argument against it. Some people want four numbers and the results page and nothing else; others find a suite's breadth is what keeps them coming back. Both free tiers exist precisely so you can find out which you are before the money moves.

A note on how this page is paid for

Mangools pays this site a share if a subscription follows a link here. The Semrush link earns nothing at all — its programme requires a thousand visitors a month and this site does not have them — so the recommendation above, which favours the cheaper tool that does pay, would read identically if neither paid anything.

That is easy to say and worth checking: the page listing every link on this site and what it earns has the full list. For the wider comparison, the eight keyword research tools with their entry prices covers six more tools, and the longer note on KWFinder goes through its plan ladder.
