Someone opens Google and types "mortgage calculator". It is one of the most fought-over searches on the internet — tens of thousands of people a month, and a difficulty score of 93 out of 100.
Two websites are waiting for that person, and they could not have made more different bets.
One of them built a calculator for almost everything, then translated the whole library into 15 languages. It has 8,694 pages.
The other has 222. No translations. No blog. A homepage that looks like it was designed in 2008, because it was.
We measured both with our own tools, expecting the big one to win comfortably. It did not. This is the story of what the smaller site does instead — and it is the most copyable thing in this whole series.
Results at a glance
Calculator.net has around 40 times fewer pages than its biggest rival, and our tools give the two sites exactly the same authority score.
It gets there by letting other people's websites publish for it.
Two sites, one search box
Omni Calculator is the one you would build if you had a whiteboard and a growth target. By its own count on the homepage, 3,915 free calculators, sorted into neat categories — biology, finance, health, sports — and then translated into fifteen languages, from German to Hindi to Ukrainian. It is genuinely impressive.
Calculator.net is the one you would be embarrassed to show your designer. Four columns of blue links on a white page. Roughly 199 calculators, all of them ending in .html, all of them in English only.
One of these looks like a modern content operation. The other looks abandoned. Hold that thought.
222 pages against 8,694
You can check the size of any website yourself, and it takes about a minute. Both of these publish a sitemap — the file a site gives Google listing everything it wants found.
That is the finding. Forty times fewer pages, and the same score.
Which raises the obvious question. If the pages are not doing the work, what is?
The site that stopped building
Look again at what Calculator.net chose not to do.
It did not translate anything. It did not write a blog. It did not build a calculator for every conceivable variation of a question. It picked the few hundred things people genuinely look up — a mortgage, a BMI, a due date, a percentage — and it built those.
Then it stopped.
Every page it does have is a working tool. There is no page on that site whose job is to rank for something and then send you somewhere else. You arrive, you get your number, you leave.
And a small site is a tidy site. When we ran it through our own audit it came back at 95 out of 100, with no warnings at all — the cleanest result of any company in this series, including several worth billions.
The line you cannot delete
Here is the part that explains everything.
Calculator.net gives its calculators away. There is a page on the site offering the mortgage calculator, the scientific calculator and a handful of others as copy-and-paste code that anyone can drop into their own website. Free, no account, no catch.
There is one condition, and it is written into the terms attached to the code. You may not remove the line that reads "powered by calculator.net".
Inside that snippet is exactly one link, and it points home.
So every website that installs the calculator starts publishing a link back. Not once — on every page where that calculator appears. A mortgage broker puts it in their sidebar and suddenly links from their entire site.
You can see the fingerprint in the numbers. Both sites have a similar number of websites linking to them. But Calculator.net receives roughly five times as many links from each one, which is exactly what happens when a link lives in somebody's template instead of in a single article.
Same score, different route
So the two sites arrived at the same place by opposite roads.
Omni Calculator earns its position the way a publisher does: cover more topics, in more languages, and collect a link here and there from each of them. It is a perfectly good strategy and it clearly works.
Calculator.net earns its position the way a utility does. It made something people wanted to install, and then it let them install it. Its pages are not the product. The product is the thing on the pages, and it travels.
The second route is the one available to a small team. You cannot out-publish a company with 3,900 calculators. You can absolutely build five that people want to embed.
Copy this in an afternoon
Four steps. None of them need a budget.
1. Find the few things people actually want. Not topics you could write about — jobs people are trying to get done. In most niches there are fewer than ten. A calculator, a checker, a converter, a template, a lookup.
2. Build one properly instead of ten badly. The reason Calculator.net's mortgage calculator gets embedded is that it works, it is fast, and it does not ask for an email first.
3. Let people take it with them. Offer it as copy-and-paste code, a plugin, or an embed. This is the step nearly everybody skips, and it is the one that does the work.
4. Put your name in the code, politely. One small credit line with one link. Not a banner, not a popup — a line that a reasonable person will leave alone because the tool is worth it.
That is the entire strategy. It is available to a website with five pages.
What you cannot copy
The head start. Calculator.net has been doing this since 2008. Those links accumulated over nearly two decades, and a credit line only compounds if people keep installing the thing.
The category. Calculators are unusually easy to give away — self-contained, useful on their own, no login. If your product only makes sense inside your own account, this route is closed and you should scale content instead, like Omni does.
And here is what we could not check:
We have no traffic figures for either site. None were available to us and none are claimed here. Everything above is page counts from public sitemaps plus our own link and audit tools.
We cannot see how many sites still run the widgets. The WordPress plugins on offer are old — the instructions still mention WordPress 2.5 — so the giveaway may be more of a legacy than an active campaign. What we can see is the link pattern it left behind.
A page in a sitemap is not the same as a page in Google. Both counts are what each site declares, not what is indexed.
Links divided by referring domains tells you how a site earns. A high ratio means something is sitting in other people's templates; a low one means links arrive one article at a time. The same report we ran on both calculator sites works on any domain.

Frequently asked questions
How many pages does each site have?
Calculator.net's sitemap listed 222 URLs when we read it on 22 August 2026, of which 199 end in -calculator.html. Omni Calculator's listed 8,694, made up of about 3,890 English pages and 4,804 translations across 15 languages: Czech, German, Spanish, French, Hindi, Hungarian, Italian, Dutch, Polish, Portuguese, Russian, Slovak, Swedish, Turkish and Ukrainian.
What were the exact link numbers?
On 22 August 2026 our Backlink Analyzer gave both sites Domain Rank 89 out of 100. Calculator.net had 31,715 referring domains and about 2.9 million links; Omni Calculator had 39,155 referring domains and about 660,000 links. So Omni has slightly more websites linking to it, and Calculator.net has roughly four and a half times more links overall.
How reliable are those figures?
We ran the Calculator.net check twice, minutes apart. Domain Rank, referring domains, the dofollow and nofollow counts, the referring IPs and the subnets all reproduced exactly. The single headline "total backlinks" figure moved between runs, which is why the article talks about link totals in round numbers rather than precise ones.
Why does one link count so much higher than the other?
Because of where the links sit. A link inside one article is one link. A link inside a widget that somebody installed in their sidebar appears on every page of their website. Calculator.net averages roughly 93 links per referring domain against Omni's 17, and that gap is what a template-level link looks like in the data.
Is "mortgage calculator" really that competitive?
Yes. Our Keyword Research tool put it at 58,151 searches a month with a difficulty of 93 out of 100, which is about as hard as it gets. The related phrase "mortgage calculator for" runs into the millions. This is not a quiet corner of the internet.
Does a small site really score better technically?
In this case, clearly. Calculator.net scored 95 out of 100 in our Website Audit with zero critical issues, zero warnings and 119 checks passed. That is the cleanest score of any company we have measured in this series. There is simply less to break.
So should I stop publishing pages?
No — but stop assuming more pages is the only lever. Omni Calculator's approach works too, and if your product cannot be given away, publishing widely is the right call. The point is that page count was not what separated these two sites, and for a small team the giveaway route is far more achievable than out-publishing a competitor.
Can I check any of this myself?
All of it. Open either site's robots.txt to find its sitemap, follow it, and count the entries — that is where the page numbers come from, and it is free. For the link figures, run any domain through our Backlink Analyzer and divide total links by referring domains.
Decide how many pages you need
Every company in this series answered the same question differently. RTINGS measures things nobody else measures. Wise turned one exchange rate into millions of pages. Zapier refuses to publish most of what it could. Canva lets its users make the pages. Booking invents new ways to want a hotel. Zillow never deletes a sold home.
Calculator.net is the first one that answered by building almost nothing.
Two hundred and twenty-two pages, a homepage that has not changed in years, and a small line of text at the bottom of a widget that thousands of other websites are quietly publishing on its behalf.
So before you plan the next thousand pages, ask a cheaper question: is there one thing you could build that other people would want to put on their own website?
And if you are wondering whether the pages you already have are earning anything — check the ratio. It takes a minute, and it tells you which kind of site you are running.
Measured on 22 August 2026. Page counts come from each site's own sitemap, fetched directly and counted by entry. Link, keyword and audit figures are free runs of our own tools; exact values are in the FAQ above.
Pages listed in a sitemap are not the same as pages indexed by Google. No traffic or revenue data for either company was available to us, and none is claimed here.
