Almost every guide to SEM keyword research is really a tool tutorial. Open Keyword Planner, type a seed word, export 800 rows, sort by volume. Then you are staring at a spreadsheet with no idea which rows deserve money.
That is the real problem. Finding keywords is easy; choosing them is expensive, because every keyword you keep is one you pay to test. A list of 800 does not buy more reach than a list of 40 — it buys the same reach, funded worse.
This guide treats SEM keyword research as a budgeting exercise: which searches carry buying intent, how Malaysian searches differ from the textbook, where the money in a keyword list goes, and why the negative list does half the work. Four datasets from ZenWeb-managed Malaysian accounts sit underneath it.
If you have not set a monthly figure yet, start with planning a search budget first — the budget decides how many keywords you can afford. The video below covers the mechanics.

Quick Answer: SEM keyword research is the process of selecting which paid searches your budget will buy, in what priority, at what match type, and which searches you will exclude. It differs from SEO keyword research because every keyword carries a live cost, so the output is a funded shortlist rather than a content plan.
Both start from the same raw list and end somewhere completely different. In SEO, a low-volume keyword costs nothing to keep. In SEM, that same keyword can quietly draw RM 400 a month before anyone notices. That one difference changes the whole method:
They still feed each other. Paid data shows which terms convert before you commit a year of content, which is why running SEO and SEM under one roof costs less than running them apart.

Quick Answer: Sort every candidate keyword into an intent tier — brand, transactional, comparison, category, informational — then fund the tiers from the top down until the budget runs out. Volume is the last thing you look at, because a high-volume informational term can cost ten times more per lead than a small transactional one.
Below is what each tier costs in practice across Malaysian accounts.
| Intent tier | Share of clicks | Conversion rate | Cost per lead (RM) |
|---|---|---|---|
| Brand (your own name) | 6% | 14.2% | RM 38 |
| Transactional (quote, price, near me) | 23% | 9.1% | RM 74 |
| Comparison (best, vs, review) | 17% | 5.4% | RM 118 |
| Category (service + Malaysia) | 34% | 2.6% | RM 236 |
| Informational (how to, what is) | 20% | 0.8% | RM 690 |
Aggregated from ZenWeb-managed campaigns, Malaysia, 2024–2026. Lead-generation search accounts only; e-commerce excluded.
Read the last two columns together. Informational searches take a fifth of the clicks and return almost nothing — RM 690 a lead against RM 74 for a transactional term. Category terms look respectable on volume and quietly eat a third of the budget at RM 236 a lead.
The rule: fund brand and transactional in full, fund comparison where you have a real differentiator, cap category terms, and keep informational out of paid search. Those searches are worth having — win them with content, not clicks. For the tier logic in depth, read which keywords carry real buying intent.
Quick Answer: Malaysians code-switch mid-query. An English service noun sits next to a Malay modifier like murah, harga or berdekatan in the same search. Keyword tools built on single-language assumptions under-report these, so they rarely make it into the planned list — even though they convert well and cost less per click.
This is what separates a locally researched list from an imported one. A planner run in English returns clean English phrases. Real Malaysian search boxes hold a blend.
| Query pattern | Share of converting terms | Median CPC | Was in the planned list |
|---|---|---|---|
| English service term only | 38% | RM 5.10 | 94% |
| English term + Malay modifier | 26% | RM 2.90 | 21% |
| English term + place name | 19% | RM 4.40 | 47% |
| Full Bahasa Malaysia query | 12% | RM 2.20 | 18% |
| Brand or product name misspelling | 5% | RM 1.60 | 9% |
Aggregated from ZenWeb-managed campaigns, Malaysia, 2024–2026. “Planned list” means the keyword existed in the account at launch.
The second row is the one that pays. Mixed-language queries produce a quarter of all converting terms at roughly half the cost per click of pure English — and only one account in five had them at launch. They arrive later, through the search terms report, if anyone reads it.
So build the list bilingually from day one, and keep a slice of budget on looser match types early so these terms can surface at all. That is the honest argument against going exact-only from the start, and the trade-off is covered in broad match versus exact match. Demand is not the constraint — Malaysia has 35.4 million internet users at 98% penetration, per DataReportal’s Digital 2026 report. Whether your list speaks the way those people type is.
Quick Answer: In a typical Malaysian search account, the top ten keywords take around 60% of the spend and deliver a slightly larger share of the leads. Everything past the first fifty keywords contributes very little of either. A long list mostly adds admin, not reach.
This is the finding that should change where SEM keyword research spends its time.
| Keyword rank group (by spend) | Share of spend | Share of leads | Cost per lead index |
|---|---|---|---|
| Top 10 keywords | 61% | 68% | 90 |
| Keywords 11–50 | 27% | 24% | 113 |
| Keywords 51–200 | 9% | 7% | 129 |
| Keyword 201 and beyond | 3% | 1% | 301 |
Aggregated from ZenWeb-managed campaigns, Malaysia, 2024–2026. Index of 100 equals the account’s blended cost per lead.
The tail is not free. Keywords past position 200 buy leads at three times the account average, and each still needs its own ad and landing destination to work. Most never get one.
So: research widely, ship narrowly. Forty to sixty funded keywords is a healthy starting account for most Malaysian SMEs. A keyword that cannot collect thirty clicks a month at your budget cannot be judged, and an unjudgeable keyword is a slow leak. The same logic makes dynamic search ads better as a discovery layer than a main campaign.

Quick Answer: Yes, and it is the half most accounts skip. Negative keywords are researched from your own search terms report, not copied from a downloadable list, because the terms worth blocking are specific to your business. Blocking is what turns a broad, cheap list into a profitable one.
Copied negative lists are quick and risky. One blocking “free”, “cheap” and “DIY” will happily block free quote and cheapest renovation contractor, both of which convert in Malaysia. Your own data is the only safe source for this half of SEM keyword research.
| Month since launch | Median negatives in account | Spend on non-converting terms | Cost per lead index |
|---|---|---|---|
| Month 1 | 12 | 38% | 100 |
| Month 2 | 47 | 29% | 88 |
| Month 3 | 88 | 22% | 79 |
| Month 6 | 164 | 15% | 68 |
| Month 12 | 251 | 11% | 62 |
Aggregated from ZenWeb-managed campaigns, Malaysia, 2024–2026. Accounts with a documented weekly search terms review. Index of 100 equals month one.
Nothing clever happened between month one and month twelve. Someone read the search terms report weekly and blocked what did not belong. Cost per lead fell roughly a third on that alone — no new keywords, no bigger budget.
Google documents the mechanics of adding negative keywords, and the search terms report is where candidates come from. If nobody has opened that report this month, start with finding the clicks draining your budget.
Quick Answer: Seven steps: pull seed terms from your own sales conversations, expand them in Keyword Planner, tier them by intent, cut anything you cannot fund to thirty clicks a month, assign match types, write the opening negative list, then group what survives. The exercise takes a working day.
Tight grouping is what makes ad testing readable — loose groups produce mushy ads that test nothing, a common reason responsive search ads underperform. It also feeds ad rank, since relevance is one of its inputs, so a tighter group can win a higher position without a higher bid.
Note what is missing: competitor spy tools. A rival’s list reflects their margins and landing pages, not yours. Run this before launch — it costs far less than discovering the list was wrong in month three, and the week-by-week management cycle assumes a researched list exists.
Quick Answer: Four checks, none technical. Count the negative keywords, look for Malay-language terms in the list, check whether brand sits in its own campaign, and ask which ten keywords took the most spend last month. A researched account passes all four in five minutes.
You do not need to audit a list line by line. Get account access, then check four things:
None of it requires you to know Google Ads. It requires the account to sit in your own name with the agency added as a user, which matters more than any contract clause. If answers come back thin, get a second read — it helps to know how to choose a paid search agency that grows revenue, and for smaller accounts, whether a consultant or an agency fits better.
Three habits round it out. Watch search impression share on funded terms. Keep assets and extensions aligned to the same themes. And make sure the destination earns the click — good SEM keyword research still fails on a weak page, which is why landing page fixes often lift leads faster than new keywords. If Google alone is not filling the pipeline, Microsoft Advertising in Malaysia runs the same list at a lower cost per click.
Quick Answer: Good SEM keyword research produces a short funded list tiered by buying intent, built bilingually for Malaysian search, grouped by the promise each ad can make, and defended by a negative list that grows every week. The discipline is subtraction, not collection.
The instinct with a keyword tool is to keep everything. Resist it. Every row you keep is a row your budget must feed, and a budget spread across 400 keywords learns nothing.
Costs are drifting upward everywhere — WordStream’s 2026 benchmark, drawn from more than 13,000 campaigns across 23 industries, puts the average cost per click at USD 5.42. Malaysian clicks sit well below that, but the direction is the same, and a loose list gets expensive faster each year. If you want a second read on the list your account runs today, or one built from your own sales conversations rather than a template, see how we run Google Ads management.
SEM keyword research is choosing which paid searches your budget bids on, at what priority and match type, and which you block. Unlike SEO, every keyword kept carries a live cost, so the output is a short funded list.
Most Malaysian SME accounts perform best with 40 to 60 funded keywords in total. Beyond that, budget spreads too thin for any keyword to gather enough clicks to judge. In ZenWeb-managed accounts, keywords past position 200 by spend buy leads at three times the account average.
No. Tools give volume and cost estimates, one input among several. They under-report mixed English-Malay queries, cannot tell you what your sales team already hears, and never suggest negatives. Your own enquiries fill those gaps.
Search terms weekly, the keyword list monthly. Weekly review is where negative keywords come from, and it is the habit separating accounts whose cost per lead falls from those where it climbs.
Usually yes, in a separate campaign. Brand terms are the cheapest converting clicks in most accounts and protect the result when a rival bids on your name. Keep them out of generic campaigns so they do not flatter blended figures.
