Picture a mid-sized Cape Town distributor of industrial components: roughly R1.2m a year of media spend, an in-house marketer wearing six hats, and a generalist agency running Google Ads alongside social, display and email for three years. The distributor is plateaued. Branded queries are expensive, non-brand growth has stalled, and nobody can explain which keywords produced quotes. The marketing lead wants to move search to a specialist without waking up to find the agency holding the admin keys, billing card and historical change log. This is the playbook for that handover.
What 'Search Advertising' Actually Covers - and What It Doesn't
Search advertising is text advertising on search engines: Google Search campaigns, Shopping and Performance Max where retail applies, and Microsoft Advertising. It excludes social, display, video and influencer. Buyers often conflate 'paid media' with 'search', then brief a scope too broad to be done well. Google's documentation on Search campaigns is the reference point.
A specialist should explain match-type strategy, negative keyword architecture and query hygiene - not just campaign naming. If the brief can't test that, it won't separate specialists from generalists.
Why South African Buyers Say 'Search Advertising' and Not 'Google Ads'
Microsoft Advertising still carries meaningful desktop and enterprise search volume in South Africa, particularly for B2B and professional services, so a Google-only brief leaves inventory untouched. Importing US terminology ('PPC', 'SEM') also signals imported expectations - offshore benchmarks, dollar ROAS targets, advice that ignores local delivery economics. A search advertising agency in South Africa should price in ZAR, apply VAT correctly and recognise that card failures and courier realities shape e-commerce conversion rates.
The Engagement Brief That Separates a Specialist From a Generalist
Write the brief around craft, not deliverables. A specialist brief asks for a documented match-type transition plan after broad match expansion; a negative keyword architecture with account, campaign and ad-group tiers; an explicit policy on brand protection versus competitor bidding; a decision on Search Partner and Display Network expansion (defaults are almost always on and almost always wrong); and a named owner for Microsoft Advertising. A generalist brief asks for 'monthly reports' and 'campaign optimisation', which cannot be verified.
Specialist Search Shop vs Full-Service Agency vs Freelancer: Which Suits Which Buyer
| Buyer profile | Best fit | Why |
|---|---|---|
| In-house team offloading execution, keeping strategy | Specialist search shop | Craft depth plus a collaborative operating rhythm |
| Mid-market e-commerce or B2B SaaS wanting full search ownership | Specialist, with CRO and feed support | Search interacts with landing pages and Merchant Center |
| Scaling brand with a generalist, needing search craft | Full-service agency with a dedicated search pod | Avoids splitting attribution across two vendors |
What a Search Advertising Agency Should Cost in South Africa: Fee Models and ZAR Ranges (Estimates)
Figures are illustrative ranges, not quotes, and exclude VAT. Management fees are subject to VAT, so a R25,000 retainer is R28,750 to the client.
| Model | Typical structure | Watch for |
|---|---|---|
| % of media spend | Commonly 10-20% (estimate) | Rewards spend, not efficiency |
| Flat retainer | R15,000-R60,000/month by complexity (estimate) | Scope creep; check account count |
| Hybrid with performance component | Base plus bonus on agreed CPA targets | Defining 'qualified' precisely |
| Hourly | Project or audit work | No continuity of learning |
The First 90 Days: Handover, Access and Guardrails
The client must retain admin ownership of Google Ads, Merchant Center, Microsoft Advertising and billing. Grant the agency standard or operating access, not admin. Keep a shared change log and require written approval for structural changes in the first month. Transparent reporting should be established before optimisation begins.
Safe Access Handover: A Working Checklist
Naming convention:
[client]-[channel]-[market]-[owner]
e.g. acme-google-za-inhouse
acme-msads-za-agency
Checklist:
[ ] Client owns Google Ads admin + billing
[ ] Agency: standard access only
[ ] Merchant Center under client login
[ ] Microsoft Advertising account client-owned
[ ] Conversion actions documented
[ ] Change log shared (Google Sheets)
[ ] Rollback: revoke agency access, retain historyIf an agency insists on owning the Google Ads account 'for billing convenience', that is a red flag. Historical data belongs to the client.

Brand vs Non-Brand: The Split That Defines Agency Value
Brand campaigns protect existing demand; non-brand campaigns create new demand. An agency reporting blended ROAS flatters itself with brand traffic it did not generate. Separate brand and non-brand in every report, and treat non-brand qualified cost per lead as the growth signal you pay for. Competitor bidding is legitimate but should be an explicit, budgeted decision - not a default - because it converts at a lower rate and affects Quality Score. Match-type strategy sits at the centre of both.
The Quiet Second Channel: Is Microsoft Advertising Worth It in South Africa?
Microsoft Advertising reaches a smaller but more enterprise-leaning, desktop-heavy audience with lighter competition, so cost per click is frequently lower. For B2B, SaaS and professional services, test it with 10-15% of search budget. For consumer e-commerce it may not justify the management overhead. Decide with data from your own account, not a vendor's slide - see Microsoft Advertising's platform overview.
Outcomes You Can Hold a Search Agency To
Avoid guarantees. Agree on targets that are measurable and that the agency controls: non-brand qualified cost per lead or CPA against a baseline; search impression share on a defined list of priority non-brand terms; brand cost per conversion efficiency; and contribution-based reporting that reconciles to your revenue system rather than platform-attributed ROAS. Search campaign structure and targeting levers determine most of this.
How to Measure Whether the Agency Is Working - Monthly
| Artefact | What it proves |
|---|---|
| Brand vs non-brand split | Whether growth is new demand or borrowed credit |
| Query-level waste review | Negative keyword hygiene is being maintained |
| Change log | Optimisation is happening and is traceable |
| Revenue reconciliation | Platform numbers tie to your systems |
Ask for the change log in month one. Agencies that cannot produce one are usually logging in to check notifications, not to optimise.
South African Operating Realities: POPIA, VAT and Payment Friction
POPIA constrains how you build remarketing lists and handle conversion data; configure consent signals before campaigns scale, and follow the Information Regulator. VAT applies to management fees, and card declines and courier delays affect e-commerce search conversion in ways a US-trained account manager will not anticipate. Prebo Digital, a Johannesburg-based agency founded in 2016 by an ex-Google employee and a Google Premier Partner (2022-2026), handles these local realities alongside search craft for e-commerce, SaaS and FMCG clients across Africa, the UK, Europe and the Middle East.
Pitfalls When Switching From a Generalist Digital Agency
- Losing historical conversion data because the old agency owned the account.
- Inheriting broad match with no negative keyword architecture.
- Search Partners and Display expansion left enabled by default.
- No documented baseline, so improvement cannot be proven.
