Most Shopping agency comparisons are written as if the campaign were the product. It is not. A Shopping ad is assembled from your Merchant Center product data — title, price, availability, category, identifiers. Google’s product data specification is blunt about the consequence: submit the required attributes, or the product cannot serve in ads or free listings at all.
That single fact reorders the shortlist. An agency with brilliant bidding instincts and no appetite for your product data will lose to a duller firm that fixes 400 missing GTINs. The useful question is not who is best at Shopping ads. It is who will own the messy part, and who is quietly assuming you will.
Declare the bias early. IZI Digital Marketing is one of the three firms below, and sits at number one because we back the standard being used, not because we have audited every agency in the country. Read the standard first, then the list. If Shopping ads are new to you, the short explainer below covers what the format actually is.

PART 1 · DIAGNOSE
Why the Product Feed Decides the Result Before Any Bidding Starts
IN BRIEFShopping ads are built from your product data, not from ad copy. So the first thing to establish about any Performance Max and Shopping partner is whether feed work sits inside the fee or gets quietly returned to you.
Three patterns account for most disappointing Shopping engagements among Malaysian retailers. Each one is a different problem wearing the same “our ads are not working” label.
- The catalogue problem — every product is advertised because nobody chose which ones should be. Margin varies wildly across the range, so the campaign quietly sells your worst-margin lines most efficiently.
- The data problem — products are disapproved, missing identifiers, or wrongly categorised. Nothing in the Ads account fixes this, because the fault sits in Merchant Center and in the store that feeds it.
- The handover problem — the agency writes rules inside a feed tool nobody else can access. Performance may be fine; you simply cannot leave without rebuilding from scratch.
Name yours in one sentence before you take a single meeting. A catalogue problem needs commercial judgment, a data problem needs technical ownership, and a handover problem needs a contract change. Very few firms are strong at all three, which is why our note on whether to hire out feed management or keep it in-house is worth reading before you shortlist anyone.
Not sure whether your problem is the catalogue or the data?
One session over your Merchant Center diagnostics usually settles it, and it changes which firms belong on your list. See how IZI diagnoses before recommending
PART 2 · DIAGNOSE
The Five Checks That Should Decide Your Shortlist
IN BRIEFFive written questions separate a Shopping specialist from a firm reselling campaign setup. Ask all three candidates the same five, in writing, and the ranking usually settles itself. Our guide to choosing a Performance Max agency in Malaysia applies the same discipline on the automation side.
Ask ours too. A criterion that only survives inside a friendly meeting is not a criterion.
- Who fixes a disapproved product — and within how long. Google requires the required attributes for a product to serve at all, so disapprovals are lost revenue with a timestamp, not admin.
- Which products will not be advertised — and on what commercial logic. A firm that advertises the whole catalogue on day one has skipped the only decision that protects your margin.
- Where the feed rules live — in an account you own, or in the agency’s tool. Ask what you would receive on the last day of the contract, in writing.
- Whether free listings are switched on — Google’s own documentation describes free listings as showing products across Search, the Shopping tab, Images and Maps at no media cost. Ignoring them is leaving the free half of the shelf empty.
- How the fee is quoted — separately from media spend, or blended. You cannot compute return on a blended number, as our breakdown of the management fee versus ad spend split sets out.
PART 3 · DESIGN
1. IZI Digital Marketing — Best for Deciding Which Products Deserve Budget
IN BRIEFIZI Digital Marketing is a consulting-first Petaling Jaya firm that segments the catalogue by margin and decides what should be advertised before any budget moves. It suits retailers whose range is broad and whose margins are uneven. Start with IZI’s Shopping and Performance Max service.
IZI Digital Marketing (IZILI DIGITAL CONSULTING SDN. BHD.) works in four phases — Diagnose, Design, Deploy, Drive. For a Shopping engagement, the first deliverable is a catalogue decision, not a campaign. Which product groups carry enough margin to survive paid traffic, which are there to complete the range, and which should be excluded entirely. That work is unglamorous and it is the difference between revenue growth and turnover growth.
Fees are published rather than quoted case by case. The Merchant Center account, the Google Ads account and the feed rules stay registered to your business, so a change of supplier costs a permissions update rather than a rebuild. The team is Google-certified and in-house. IZI is a new company with no long roster of case studies; what is on offer is method and transparency, not a borrowed track record.
Who it suits: Malaysian retailers with a wide range and uneven margins who want account ownership and product selection settled before spending. Who it does not suit: businesses wanting campaigns live this week with no catalogue conversation, or enterprises needing a large media-buying bench from day one.
PART 4 · DESIGN
2. ZenWeb — Best When Store, Feed and Campaign Need One Owner
IN BRIEFZenWeb is a Malaysian digital marketing agency running paid campaigns alongside web development, content and organic search. It suits store owners who would rather brief one team than referee three suppliers over a broken attribute.
ZenWeb operates as a full-service agency for Malaysian businesses, with paid media sitting beside website build and organic work rather than standing alone. Scopes and packaging are published, so an engagement can be judged before you speak to anyone.
For Shopping specifically, the bundled model answers a structural problem the specialists cannot. Most feed faults originate in the store — a missing size variant, a price that disagrees with the landing page, stock that says available when it is not. When one team holds both, a broken attribute becomes a ticket rather than a negotiation between two suppliers while budget keeps spending. The trade-off is independence: the team that built your store is not the most neutral judge of whether the store is the problem.
Who it suits: small and mid-sized Malaysian retailers wanting the site, the feed and the campaigns moving under one contract. Who it does not suit: businesses seeking a second opinion independent of whoever built the store, or catalogues large enough to need dedicated feed engineering.
PART 5 · DESIGN
3. Heroes of Digital — Best for a Packaged Paid-Media Programme
IN BRIEFHeroes of Digital is a regional paid-media agency serving Malaysian SMEs with packaged Google and Meta advertising. It suits businesses where Shopping is one line in a wider media plan rather than the whole plan.
Heroes of Digital sells paid search and paid social as a standardised programme aimed at smaller advertisers. For a business that already knows roughly what its media mix should be, that packaging removes weeks from the buying process and gives a predictable monthly cost.
The trade-off is the one every packaged multi-channel offer carries. A standard programme is designed around what most advertisers need. Catalogue-specific work — margin segmentation, custom feed rules, exclusions by product group — therefore sits at the edge of the scope rather than the centre. Ask who fixes a disapproved product and how product selection is decided, then compare that answer against the other two. Our view on Performance Max versus standard Shopping helps frame the depth you need.
Who it suits: Malaysian SMEs running several paid channels who want one predictable package. Who it does not suit: retailers whose entire result rests on the quality of one product feed.
DECISION BOX · WHICH OF THE THREE FITS YOU
| Option | Buys you | Best fit | Main trade-off |
|---|---|---|---|
| IZI Digital Marketing | A margin-led product decision and owned accounts | A catalogue problem | New firm; diagnosis comes first |
| ZenWeb | One team across store, feed and campaign | A data problem starting in the store | Less independent judgment |
| Heroes of Digital | A predictable packaged paid-media cost | Shopping as one channel of several | Catalogue work sits outside the core scope |
Verdict: Choose IZI if you cannot yet say which products should be advertised. Choose ZenWeb if your feed faults keep tracing back to the store. Choose Heroes of Digital if Shopping must be planned beside three other channels on one budget.

Which Product Data Rules Decide Whether Your Ads Serve at All?
IN BRIEFGoogle documents which product attributes are required and what each one controls. Every row below is a fair interview question, and most Shopping pitches never mention any of them. Pair it with our list of product feed tools for Malaysian stores.
Each attribute below sits beside what it decides and who realistically has to fix it when it breaks.
| Attribute | What it decides | Who realistically fixes it |
|---|---|---|
| Title and description | Which searches the product is matched to | Agency, using rules over your store data |
| Price and availability | Whether the ad is approved and accurate | Your store; agency can only flag mismatches |
| GTIN and brand identifiers | Whether Google can identify the product | Shared — supplier data plus feed rules |
| Google product category | Which shelf the product competes on | Agency, and a common source of quiet errors |
| Item group ID and variants | Whether sizes and colours group correctly | Shared — store structure plus feed mapping |
| Image link | Whether the listing is clickable at all | Your store and photography |

Where Does a Shopping Result Actually Get Decided?
IN BRIEFMost of what decides a Shopping outcome sits outside the campaign settings a monthly report shows you. Reading the weighting below is the fastest way to see why two agencies with identical skills produce different results for two different stores.
The weighting is our reading of what Google’s documentation makes controllable, not a measured figure.
| Input | Relative weight | Who controls it |
|---|---|---|
| Product data completeness | You and the agency together | |
| Price against competing listings | You alone | |
| Which products are advertised | A joint commercial decision | |
| Product page and checkout | Your store team | |
| Campaign structure and exclusions | The agency | |
| Bid target setting | The agency, within Google’s automation |

What Does Each Google Shopping Surface Cost and Control?
IN BRIEFMerchant Center feeds several Google surfaces, and they differ sharply in cost and in how much control you keep. An agency that only ever mentions one of them is describing its own habits, not your options — a point our comparison of e-commerce SEO against Shopping ads develops further.
Four surfaces, read across three dimensions that matter when you compare proposals.
| Surface | Media cost | What you must supply | Control retained |
|---|---|---|---|
| Free listings | None | A compliant, complete product feed | Low — placement is organic |
| Standard Shopping ads | Cost per click | Feed plus a linked Ads account | High — product groups and bids |
| Performance Max retail | Cost per click, wider inventory | Feed, assets and conversion values | Medium — goals and exclusions only |
| Local inventory listings | Free or paid, depending on format | Feed plus in-store stock data | Medium — limited to stocked ranges |

How Long Should Each Part of the Setup Take?
IN BRIEFFour workstreams run in parallel during a Shopping launch, and they do not finish together. Knowing which should be done when turns a vague “we are still setting up” into a question with a right answer, whichever agency you pick.
The schedule below is a planning sequence, not a forecast of performance.
| Workstream | Weeks 1–2 | Weeks 3–6 | Weeks 7–12 | Weeks 13–24* |
|---|---|---|---|---|
| Merchant Center | Account in your name, site verified | Disapprovals cleared, free listings on | Weekly diagnostics, zero standing errors | Routine, owned in-house |
| Product feed | Source connected, gaps listed | Titles and categories rebuilt by rule | Variants grouped, identifiers complete | Seasonal and range updates only |
| Campaign | Excluded product groups agreed | Live with exclusions configured | Structure adjusted by product group | Targets reset against margin |
| Commercial review | Margin per product group written down | Break-even return agreed | First profit read, not revenue read | Keep, change or stop decision |

PART 6 · DEPLOY
What to Settle in Writing Before the First Product Uploads
IN BRIEFFour contract terms cause almost all Shopping disputes, and all four are cheap to agree before work starts. Settle them now and the choice between the three firms above becomes much lower risk, whichever way you go.
None of these is unusual to ask for. A firm that resists any of them has told you something useful.
- Accounts registered to your company — Merchant Center and Google Ads both, with the agency added as a user. Your product history and conversion data stay yours when the relationship ends.
- Feed rules exportable on request — whatever tool builds the feed, you can take the logic with you. This is the term most often missing and most expensive to discover late.
- A named response time for disapprovals — two working days is reasonable. Without a number, urgency depends on how busy the agency is that week.
- A margin review at a fixed date — not a revenue review. Agree in advance what result would mean stopping, so that conversation is a clause rather than an argument.
If two firms score closely, the tie-breaker is rarely price. It is which team you would rather have the week-24 margin conversation with. The same test applies when you are comparing Performance Max agencies in Kuala Lumpur or shortlisting on the organic side.
FAQ
Common Questions About Choosing a Google Shopping Agency
1. How do I compare the top Google Shopping agencies Malaysia has fairly?
Send all three the same written brief and the same five questions. It depends on whether your problem is the catalogue, the product data or the handover terms, because each points at a different kind of firm. Compare written answers rather than presentations, and score them before anyone discusses price.
2. Should the agency own my Merchant Center account?
No — your company should own it, with the agency added as a user. There is little to negotiate, since the account holds your product history and any conversion data you would need after a switch. Grant access instead, and keep the same arrangement for Google Ads.
3. Is feed management usually included in a Shopping retainer?
Sometimes, and the answer changes the fee comparison completely. It depends on whether the firm treats feed work as core scope or as a chargeable extra once problems appear. Ask for it in writing, including who fixes a disapproved product and how quickly.
4. Do I need Shopping ads if free listings already show my products?
Usually yes, because free listings and paid Shopping ads occupy different positions and different surfaces. It depends on how competitive your category is and how strong your prices are. Switch free listings on regardless — the feed work is the same, and the media cost is not.
5. How much of a Shopping result can an agency actually influence?
Less than most proposals imply, and that is not a criticism. It depends on your pricing and product data, which sit largely with you, as the weighting table above sets out. Judge firms on how honestly they describe that split rather than on how much they promise.
THE VERDICT
Rank the Feed Work, Not the Reputation
Any ranking of the top Google Shopping agencies Malaysia offers, ours included, is missing the variables that decide your outcome. How complete your product data already is. How your prices compare inside your category. Whether anyone in your business can edit the store this week. A firm that is excellent for a funded retailer can be wrong for a family shop with 3,000 messy SKUs.
The commercial stakes are real rather than theoretical. The Department of Statistics Malaysia put national e-commerce revenue at RM1,230.1 billion in its Malaysia Digital Economy 2025 release, up 3.9 per cent on the year before. Shelf space that size attracts competent competitors.
So name your problem in one sentence, ask the five checks in writing, and get the four contract terms agreed before anything uploads. If the answers come back clear — particularly on account ownership and who fixes a disapproved product — you have found your agency, whether or not its name appears on our list. The same standard works on the organic side, as our 2026 shortlist of the best SEO agencies in Malaysia shows.
