Keyword tools answer a question about queries: what are people searching for, how often, and how hard would it be to rank. They are very good at it, and building a competitor would take years and a great deal of money.
We answer a different question, about sites rather than queries: which websites are already winning, on what authority, in which niche, earning how.
Both are useful. They are not alternatives, and the honest framing is sequence rather than substitution — site discovery first, keyword research once you know where you are going.
The comparison, plainly
| Question | Keyword tool | SERPHeroes |
|---|---|---|
| Which keywords should I target? | Built for this | Not our job |
| How many people search this term? | Built for this | We do not hold volume data |
| Who links to this page? | Built for this | We hold counts, not the links |
| Which sites rank far above their authority? | Manual, one domain at a time | One filter |
| Which new sites are growing without links? | Hard to surface | One filter |
| Who held through the last core update? | Per-domain lookup | A sorted list |
| How do sites in this niche earn? | Not covered | A column |
What we genuinely do not do
Worth stating without hedging, because discovering it after paying is a bad experience and an avoidable one.
- No keyword volumes. We hold no search volume data at all. If that is what you need, this is the wrong product.
- No backlink index. We show referring domain counts. We cannot tell you which sites link to a page or show you anchor text.
- No rank tracking. We do not follow your positions over time.
- No site audit. No crawler, no technical issues report.
- No content tooling. No briefs, no optimisation scoring.
That is most of what a general SEO suite offers. We are deliberately narrow, and a narrow tool is only worth having if the thing it does is something you actually need.
The question we exist for
Given a niche, which sites are winning traffic without the authority that would normally explain it — and what do they have in common?
That question is answerable with a keyword tool, in the way that anything is answerable given enough time. You would check domains one at a time, record DR and traffic, look up each one’s age, and form an impression after a few days.
The difference is that a filter across a hundred thousand domains returns the same answer in seconds and does not depend on which domains you happened to think of. That is the entire proposition.
Where each belongs in the sequence
- Choose a niche. Site discovery — are low-authority sites winning here? This is us.
- Confirm demand. Is there search volume behind the topics? This is a keyword tool.
- Plan the content. Which specific queries, in what order? Keyword tool.
- Find link prospects. Which sites in this niche have real readers? Us, filtered by traffic.
- Track results. Are positions moving? Keyword tool, or Search Console.
Steps one and four are where we are genuinely better, and they happen to be the steps most people skip. The method for step one is set out in finding high traffic, low competition niches, and for step four in building guest post lists from traffic data.
On keyword difficulty
One genuine disagreement rather than a feature gap. Difficulty scores are derived from the backlink profiles of the pages currently ranking, which describes how strong the incumbents are — not whether they can be displaced.
A well-linked page nobody has touched since 2019 is frequently easier to beat than a weaker page that is actively maintained. The score cannot see the difference, and the same applies to domain rating used as a proxy for difficulty.
Looking at who is actually winning, and on what authority, answers the underlying question more directly. That is a reason to use both tools rather than a reason to distrust one.
What we would improve first
Since this is meant to be an honest comparison, the gaps we are most aware of are worth naming too.
Our traffic and revenue figures are estimates, not measurements, and we say so on every page that shows them. The index refreshes monthly, which means a site that moved sharply last week will not show it yet. And coverage is deeper in English-language niches than elsewhere, though non-English opportunity hunting is one of the things the language filter exists for.
None of those is a reason not to use the product for what it does. They are reasons not to treat any single figure as authoritative, which is a caution we would give about every tool in this category including the large ones.
Who this is not for
If you already know your niche, have your keyword map, and need rank tracking and audits, we add very little. If you manage a single established site and never research new territory, the same applies.
We are most useful to people who evaluate opportunities — affiliate operators choosing what to build, buyers assessing a site before purchase, agencies sizing a new client’s market, link builders who want prospects with readers rather than metrics.
Nielsen Norman Group’s long-running research on how people actually behave in search interfaces makes a related point about tools generally: the ones that get used are the ones that answer the question the person arrived with, rather than the question the product would prefer to answer.
There is a free tier with daily limited queries, which exists so you can find out whether the question we answer is one you have. That is a more reliable test than any comparison table, including the one above.
Frequently asked questions
Is SERPHeroes an alternative to Ahrefs or Semrush?
No. Those tools answer questions about keywords and backlinks and we hold neither dataset. We answer a question about sites — which are winning, on what authority, in which niche, earning how — which is a different job that sits earlier in the process.
Do you provide keyword search volumes?
We do not hold search volume data at all. If keyword volume is what you need, a dedicated keyword tool is the right purchase and we are not a substitute for one.
Can I see who links to a site?
Not individually. We show referring domain counts as a measure of authority, but we do not operate a backlink index, so anchor text and individual linking pages are outside what we can show.
What do you do that a keyword tool cannot?
Filter a large index by domain rating, traffic, niche, language, monetisation model and Google update impact at the same time. That surfaces sites ranking above their authority as a list rather than as something you assemble domain by domain.
The takeaway Keyword tools answer questions about queries. We answer questions about sites. If you need volumes, backlinks, rank tracking or audits, buy a keyword tool — and use us for the step that comes before it.
