Working With Two Agencies: Turf and Attribution

The Short Answer: Working with multiple agencies can pay off when each one owns a clearly separate job, such as paid search with one and social content with the other. It fails when turf overlaps and each agency reports its own platform numbers. Before both start, write down who owns which channel, keywords and audiences, and agree one source of truth for conversions that neither agency controls.

Many Malaysian businesses end up with two agencies without ever planning it. One was hired for the website and SEO years ago. Another came in last year to run Facebook and Instagram ads. Both send monthly reports, both claim a good month, and yet sales have barely moved. Somebody is taking credit for the same customer twice.

This guide from IZI Digital Marketing is for the owner or marketing manager holding both contracts. It covers where two agencies clash, how to split the turf so they stop stepping on each other, and which attribution rule should settle arguments about who drove the sale. The short video below explains how multi-touch attribution works, which is the root of most disputes between agencies.

PART 1 · DIAGNOSE

Should You Work With Multiple Marketing Agencies at Once?

IN BRIEFYes, if each agency owns a job the other cannot touch and you have someone with time to coordinate them. No, if you are hoping two agencies will compete and push each other harder. Before adding a second one, compare what a single digital marketing agency in Malaysia could cover on its own.

Working with multiple agencies is not a problem in itself. Large brands run five or six at once. The difference is that they also employ a marketing team whose main job is to coordinate them. An SME usually has the agencies but not the coordinator, so the owner ends up refereeing. The common setups carry very different levels of risk:

Setup Example split Clash risk
Split by skill Web and SEO with one; video and content production with another Low, because outputs rarely compete for credit
Split by channel Google Ads with one; Meta ads with another High, because both chase the same conversion
Split by market or brand One agency for the Malaysian site, another for Singapore Low to medium, if geo-targeting is kept clean
Lead agency plus specialist One agency owns strategy and reporting; a specialist runs one channel under its plan Medium, depending on how clear the reporting line is

If you are weighing whether a second agency is worth it at all, our comparison of a full-service vs specialist agency sets out when one broad partner beats two narrow ones.

Bottom Line: A split by skill rarely causes trouble. A split by channel almost always does unless you settle turf and attribution in writing first.

Where Do Two Agencies Usually Clash?

IN BRIEFMost clashes come from four places: both agencies claiming the same conversion, overlapping audiences, bidding on the same brand keywords, and edits to shared tracking. Few are about strategy. Most can be prevented in the brief, which is why a clear digital marketing RFP should name boundaries before either agency signs.

The top row matters most because it drives budget decisions. If both agencies claim the same sale, you will fund both as if each earned it. Brand keywords are a close second in cost: a paid search agency bidding on your name can look brilliant while mostly catching people your SEO would have captured anyway. Our guide on whether to bid on your own brand name helps you decide who should own that traffic.

PART 2 · DESIGN

How to Split Turf Between Two Agencies

IN BRIEFWhen working with multiple agencies, split turf by asset, not just by channel. Name the owner of every account, keyword set, audience list, landing page and tracking tag. Put that list into each agency’s contract so boundaries survive staff changes. The digital marketing contract terms guide shows where such clauses sit.

“Agency A does Google, Agency B does Meta” sounds clear. Then Agency B starts a Google Display campaign for retargeting, or Agency A edits the landing page that B’s ads point to. A turf map closes those gaps. Cover at least these five assets:

  • Ad and analytics accounts: each account is owned by your company, with one named agency holding edit rights and the other on read-only access.
  • Keywords and search terms: who bids on your brand name, competitor names and core service terms, and who handles SEO for the same terms.
  • Audiences: who owns website visitor lists, customer lists and lookalikes, and which exclusions each agency must apply.
  • Landing pages and the website: one owner for edits, with a simple request process for the other agency.
  • Tracking setup: one owner for Google Tag Manager, GA4 key events and the Meta pixel. Nobody else publishes changes.
Consultant’s Note: The single most useful clause is the one that says who owns tracking. When both agencies can publish tags, one of them will eventually “fix” a conversion event in a way that happens to flatter its own channel. It is rarely deliberate, but the result is the same. Give tracking to the agency or person with the least to gain from the numbers.

Communication needs a home too. Each agency’s account manager should know who the other one is and have a direct line to them. Our guide to what a good agency account manager looks like covers the habits that make this work.

Bottom Line: A channel split is a starting point, not a boundary. Write down who owns each account, keyword set, audience, page and tag, and put it in both contracts.

Why Do Both Agencies Claim the Same Sale?

IN BRIEFBecause each ad platform counts any conversion it touched, using its own rules. A customer who saw a Meta ad and later clicked a Google ad can be counted once by each platform. Add the two reports together and you get more sales than your CRM holds. Google Ads conversion tracking with GA4 is where the fix starts.

One Month, 100 Real Enquiries: What Each Report Shows
Illustrative example of how 100 real enquiries recorded in a CRM can appear as more conversions when Google Ads and Meta Ads each report their own attributed results, compared with GA4 and the CRM.
Report Enquiries credited Why the number differs
Google Ads (agency A’s report) 58 Counts any conversion after a Google ad interaction
Meta Ads (agency B’s report) 52 Includes view-through conversions inside its attribution window
Both agency reports added together 110 Shared customers counted twice
GA4, all channels 94 One credit per key event, split across channels; misses some phone and walk-in leads
CRM (actual enquiries) 100 Each real person counted once, from every source

Illustrative model by IZI Digital Marketing, built on the attribution rules described in Google Ads and Meta Business Help Center documentation, applied to a Malaysian SME running both channels, 2026. Figures are an example, not measured client data.

Neither agency is lying. Google explains in About data-driven attribution that its model shares credit among Google ad interactions on the path. Meta’s About Attribution Models and Attribution Settings page explains how its own windows and view-through counting work. Each platform only sees its own touchpoints, so each tells the truth about a slice and neither sees the whole path.

PART 3 · DEPLOY

Which Attribution Rule Should Settle Disputes?

IN BRIEFPick one neutral referee that neither agency controls, and agree it before the first report. For most SMEs that is GA4 for channel credit, checked against the CRM for real lead numbers. Platform reports stay useful for each agency’s own tuning. Our guide to GA4 reporting metrics that matter shows what to read.

There is no perfect attribution model, only a fair one both agencies accept in advance. Google’s Get started with attribution page notes that GA4 now offers data-driven and last-click models only, having retired first-click, linear, time-decay and position-based models in November 2023. That narrows the choice to four practical options:

DECISION BOX · CHOOSING A SOURCE OF TRUTH FOR TWO AGENCIES

Source of truth Choose it when Watch out for
Each platform’s own report Never as the referee; only for in-platform tuning Totals that exceed real sales
GA4, last click Low conversion volume and a short buying cycle Undervalues awareness work such as social video
GA4, data-driven Steady conversion volume and several touchpoints per customer A black box both agencies may question
CRM source field plus holdout tests Leads close offline, by phone or WhatsApp Needs disciplined sales staff to record the source

Verdict: Use GA4 as the referee for channel credit and the CRM as the referee for how many real leads exist. Where GA4 and the CRM disagree by more than about 15%, fix tracking before arguing about credit.

Write the chosen rule into both agencies’ reporting requirements. Our guide to agency marketing reports explains how to ask for a “shared view” page in each monthly report that uses the agreed referee rather than platform numbers.

Bottom Line: The best attribution model is the one both agencies agreed to before the numbers came in. Choose it at kick-off, not in the middle of a dispute.

BENCHMARK BRIEFING 3 OF 4

How Much Does Double-Counting Grow Over Time?

IN BRIEFWithout shared rules, overclaiming tends to grow as both agencies build retargeting pools from the same visitors. With a turf map, exclusions and one referee, it stays small. The gap is widest where Google Ads management and Meta retargeting chase the same site visitors.

Combined Agency-Reported Conversions as a Share Above Real CRM Leads, by Month (%)
Illustrative time series of how far the combined conversions reported by two agencies exceed real CRM leads at months 1, 3, 6, 9 and 12, with no shared rules compared with a turf map, audience exclusions and one agreed source of truth.
Month No shared rules Turf map + exclusions + one referee
Month 1 +10% +8%
Month 3 +20% +8%
Month 6 +30% +6%
Month 9 +35% +5%
Month 12 +40% +5%

Illustrative model by IZI Digital Marketing, built on how retargeting audiences and attribution windows overlap as two agencies’ campaigns mature for a Malaysian SME, 2026. Figures show a pattern, not measured client data.

The “no rules” line climbs because retargeting pools fill up with the same people over time. Early on, each agency reaches mostly different customers. By month six, both are showing ads to your recent site visitors, and both count the resulting enquiries. The “with rules” line never reaches zero because some genuine overlap always remains, and that is fine as long as the referee handles it.

PART 4 · DRIVE

How to Manage Two Agencies Month to Month

IN BRIEFWorking with multiple agencies runs best on one calendar, one shared report view and one joint meeting a month. Give each its own service levels so you can judge them separately. Our guide to a marketing agency SLA covers what each agreement should commit to.

Five steps to run two agencies without a turf war

  1. Hold a joint kick-off. Put both agencies in one meeting to agree the turf map, audience exclusions and the attribution referee, then circulate the notes in writing.
  2. Share one campaign calendar. Launches, promotions and landing page changes go on one calendar both agencies can see, so offers and timing do not clash.
  3. Use one shared report view. Each monthly report includes a page based on the agreed referee, showing combined leads against CRM numbers.
  4. Meet together once a month. A 30-minute joint call covers overlaps, tracking changes and next month’s plans before each agency’s separate review.
  5. Review turf every quarter. Update the turf map when you add a channel, a market or a new campaign type, and re-sign it with both agencies.

Budget moves are where fairness gets tested. If you shift spend from one agency’s channel to the other, base it on the referee’s numbers, not on whichever report arrived first. This is also where two channels start to work as one plan, the idea behind an omnichannel marketing approach.

Bottom Line: Two agencies need one rhythm. A shared calendar, a shared report page and one joint call a month prevent most disputes before they start.

How Much of Your Time Do Two Agencies Take?

IN BRIEFRoughly double the management time of one agency when turf is unclear, with much of the extra going to disputes. Clear turf or a lead agency brings it back down. Count that time as a real cost when comparing options on the digital marketing agency pillar.

The dispute hours are the ones to eliminate. Every hour spent arguing over credit is an hour not spent on offers, pricing or sales follow-up, which usually move results more than either agency can.

THE VERDICT

Two Agencies Work When Turf and Credit Are Settled First

Working with multiple agencies is a sound choice when each one owns a distinct job, one neutral source of truth settles credit, and someone has the time to run a shared rhythm. It is a poor choice when the aim is to make agencies compete, or when both are chasing the same buyer on different platforms with no exclusions.

If the setup already feels like refereeing, you have three options: write a turf map, appoint one agency as lead, or consolidate. Our guide on when to change your marketing agency helps with the last decision. Whichever you choose, the same rule holds for SEO services, paid search or Meta ads: settle ownership and the referee before judging results.

FAQ

Frequently Asked Questions

1. Is it a good idea to work with multiple marketing agencies?

It can be. It depends on whether each agency owns a separate job and whether you have time to coordinate them. Splits by skill or market work well; splits by channel need a written turf map and one agreed source of truth for conversions.

2. Why do my two agencies report more sales than I actually made?

Because each ad platform counts conversions it touched. How much they overlap depends on your audiences and attribution windows, but a customer who saw both agencies’ ads can be counted by each. Compare combined totals against your CRM to see the gap.

3. Who should own tracking when two agencies are involved?

One party only, ideally the one with least to gain from the numbers. That may be an in-house person, a lead agency or an independent consultant, depending on your team. Everyone else gets read access and asks before tags change.

4. Should both agencies bid on my brand name?

No. Only one should, and only if brand bidding is worth it for you. That depends on whether competitors bid on your name, so assign brand terms to one owner and have the other agency add them as negatives.

5. Should I appoint a lead agency?

Often, yes. It depends on how much coordination time you have. A lead agency that owns strategy, tracking and the shared report usually cuts your management load and ends most disputes about credit.
