The question behind the question
Nobody types will AI replace PPC agencies as a philosophical question. They type it as a budget-defence question. The real ask is: do I still need this line item next quarter?
That's a fair question. Google's Smart Bidding, Meta's Advantage+, and Amazon's DSP already do the tactical work junior media buyers used to do. If that's what an agency is selling, the honest answer is yes, AI is replacing them.
What AI actually does well in advertising
Bidding. Budget pacing across time-of-day. Query mining for negative-keyword candidates. Creative fatigue detection. Automatic asset assembly in Advantage+ and Performance Max. Anomaly detection on conversion signal. Every one of these tasks used to consume 40 to 60 percent of a media buyer's week. Now they're one-click automations that run 24/7 with better data than a human could hold.
This is the honest news for agencies: if any of the above is your value proposition, you're being outperformed by the platform for free.
What AI does badly (or not at all)
AI cannot decide what a good ROAS is for your margin. It cannot restructure a botched campaign hierarchy. It cannot write ad copy that survives your compliance team, or brief the creative your customers actually respond to, or reject an account manager's over-eager PMax expansion. It cannot look at your Shopify data and tell you the platform's reported ROAS is 30 percent inflated.
Most of all, AI cannot decide when NOT to spend. Every AI system is optimising toward a signal you gave it. If the signal is wrong, the AI is confidently wrong at scale.
What iClick has automated (and what we haven't)
Automated: bidding (via Smart Bidding + tROAS), budget pacing alerts, creative fatigue detection on Meta, query mining pipelines feeding weekly negative-keyword updates, GA4 <> Google Ads discrepancy monitoring, LSA suspension alerts.
Stayed human: campaign hierarchy decisions, margin-aware ROAS target-setting, ad copy strategy (not the copy itself, the strategy), creative brief writing, Performance Max asset-group structure choices, monthly account narrative, and any decision to cut spend.
Roughly 30 percent of what we did in 2022 is now automated. The 70 percent that isn't is the 70 percent that most needs to be right.
How to know if your agency is being replaced (or replacing itself)
Six signals: (1) they present monthly on activities they did, not decisions they made; (2) their reporting has never once told you to spend less; (3) they can't explain how their reported ROAS reconciles with your Shopify or CRM data; (4) they refuse to name what specifically they automated versus kept human; (5) their pitch says AI but their reports look like 2019; (6) the strategist named in the sales cycle doesn't show up on your monthly call.
Any two of the above and you're paying for the wrong layer.
