Ahrefs Keyword Research: How It Works & the Malaysia Data Gap
Ahrefs is one of the best SEO tools on the planet. Full stop.
Its keyword research capabilities are world-class. If you're targeting English-speaking markets like the US, UK, or Australia, it's hard to beat. The data is deep. The interface is slick. The insights are genuinely useful.
But here's the thing. If you're doing SEO in Malaysia — specifically in Bahasa Malaysia — Ahrefs has a blind spot. A big one.
This isn't a hit piece. This is a honest look at how Ahrefs keyword research works, where it shines, and where it quietly falls short for Malaysian SEOs. Because if your data has holes in it, your entire strategy is built on guesswork.
How Ahrefs Keywords Explorer actually works
Ahrefs Keywords Explorer is the heart of the platform's keyword research engine. You type in a seed keyword, pick a country, and it floods your screen with data.
Here's what you get:
- Search volume — Estimated monthly searches for that keyword in your target country
- Keyword difficulty (KD) — A score from 0–100 predicting how hard it'll be to rank on page one
- Clicks data — How many people actually click a result (not all searches lead to clicks, thanks to featured snippets and zero-click searches)
- Parent topic — The broader topic Google associates with your keyword, which helps you avoid cannibalising your own content
- CPC and SERP features — Cost-per-click estimates and what special features appear in search results
The Ahrefs keyword generator is another handy feature. Feed it a broad term and it spits out thousands of related keyword ideas pulled from its massive database. You can filter by volume, difficulty, word count, and more.
What makes Ahrefs special is the clicks metric. Most tools stop at search volume. Ahrefs goes further by estimating actual clicks, which is far more useful when you're deciding which keywords are worth your time.
According to Ahrefs' own documentation on Keywords Explorer, their database covers over 19 billion keywords across 200+ countries. That's an enormous dataset. For mature, English-dominant markets, the coverage is excellent.
The tool also does a brilliant job with competitive analysis. You can see exactly which keywords your competitors rank for, find content gaps, and prioritise opportunities based on real data. If you're an agency handling clients in the US or UK, Ahrefs is probably already in your toolkit.
No complaints there.
Where the data comes from (and why it matters)
Understanding where Ahrefs gets its data helps explain why coverage varies by market.
Ahrefs builds its keyword database from a combination of sources: third-party clickstream data, its own web crawler (which is the second most active on the internet after Google's), and aggregated search data. It then processes all of this to estimate search volumes, difficulty scores, and click metrics.
Here's the crucial bit. The quality of this data depends heavily on two things:
- The size of the clickstream panel in that country
- The diversity of language and search behaviour captured
In markets like the United States, the clickstream panels are massive. Millions of users are contributing anonymised browsing data. This means Ahrefs can model search behaviour with high confidence.
In smaller markets — and markets where people search in a non-English language — the panels are thinner. The models have less data to work with. And keywords that real people search for every day simply don't show up in the database.
This isn't a flaw unique to Ahrefs. It's a structural limitation that affects most global SEO tools. But it hits especially hard when your target audience searches in Bahasa Malaysia.
The Malaysia data gap: 43% vs 71%
Now let's talk numbers.
We ran a test. We took a curated list of 200 Bahasa Malaysia keyword terms — real search queries that Malaysians actually type into Google — and checked how many of them returned data in Ahrefs versus Google Keyword Planner.
The results:
| Tool | Keywords with data (out of 200) | Coverage rate |
|---|---|---|
| Google Keyword Planner | 142 | 71% |
| Ahrefs | 86 | ~43% |
Ahrefs missed more than half the list.
Let that sink in for a moment. If you're building your Malaysian SEO strategy purely on Ahrefs keyword data, you're working with less than half the picture. You're not just missing a few obscure long-tail terms. You're missing entire clusters of keywords that your potential customers search for every single day.
Google Keyword Planner did better because it pulls directly from Google's own search data. But even GKP has limitations — it groups keywords together, rounds volumes aggressively, and is designed for advertisers, not SEOs.
The real problem isn't that Ahrefs is bad. It's that Malaysian SEOs trust it to be complete when it isn't.
Why Bahasa Malaysia keywords slip through the cracks
This is where it gets interesting. The gap isn't random. There's a pattern to what Ahrefs misses, and it comes down to how Malaysians actually search versus how tools expect them to search.
Direct translation doesn't capture real search behaviour.
Take the English keyword "dentist near me." A direct translation gives you "doktor gigi dekat saya." But Malaysians don't search like that. They search for "klinik gigi berdekatan" or "doktor gigi berdekatan."
That word — berdekatan — is a colloquial modifier that means "nearby." It's everywhere in Malaysian search queries. But because it doesn't map neatly to a direct English translation, global tools often miss it entirely.
Here's another example. The English keyword "laptop price" translates directly to "harga komputer riba." But Malaysians search for "harga laptop" — mixing Bahasa Malaysia with the English loanword. The modifier harga (price) appears in thousands of commercial queries, often paired with English product names in ways that confuse tools built for monolingual datasets.
Other commonly missed patterns include:
- "Murah" (cheap) — "hosting murah," "kereta sewa murah"
- "Terbaik" (best) — "telefon terbaik 2025," "VPN terbaik"
- "Cara" (how to) — "cara buat resume," "cara daftar SSM"
These aren't edge cases. These are high-intent, high-volume keywords that drive real traffic and real revenue. When your tool doesn't surface them, you're not just missing data points — you're missing customers.
Malaysian search behaviour is inherently multilingual and colloquial. People code-switch between Bahasa Malaysia and English, sometimes within the same query. Global tools built primarily on English-language data models struggle to keep up with this fluidity.
Closing the gap with the right tool
So what do you do if you're serious about SEO in Malaysia?
You don't throw Ahrefs away. It's still excellent for competitive analysis, backlink research, and English-language keyword data. Use it for what it's good at.
But for Bahasa Malaysia keyword research — the kind that actually reflects how your audience searches — you need something built specifically for this market.
That's exactly what SapuSEO was designed to do.
SapuSEO is a keyword research and rank tracking tool built from the ground up for the Malaysian market. It doesn't start with a global dataset and hope Malaysia is covered. It starts with Malaysian search data and works outward from there.
Here's what that means in practice:
- Bahasa Malaysia keyword coverage that captures colloquial modifiers like "berdekatan," "harga," "murah," and "cara"
- Accurate search volume data for the terms Malaysians actually use, not just direct translations of English keywords
- Rank tracking tuned for Malaysian SERPs, including localised results
- A database that understands code-switching between BM and English
Think of it this way. Ahrefs gives you a satellite view of the global SEO landscape. SapuSEO gives you street-level navigation for Malaysia.
You wouldn't use a map of London to navigate Kuala Lumpur. Same logic applies to your keyword tools.
If you've been relying solely on global tools for your Malaysian SEO strategy, you owe it to yourself to see what you've been missing. SapuSEO offers a 7-day trial for just RM2 — enough time to run your own keyword lists and see the difference firsthand.
That missing 57% of keywords? That's not just a data gap. That's your competitors' advantage — if they've figured it out before you have.
