Enhanced CPC Is Gone. Your Campaigns May Not Know.

Your Google Ads account changed on August 31, 2026 — and if you did not check the Bid Strategy column that week, you almost certainly missed it. The enhanced CPC sunset happened silently: no pause, no alert, and no confirmation required from you.

What Enhanced CPC Was — and Why Its Disappearance Is Not Obvious

Enhanced CPC was a Google Ads bidding strategy that adjusted your manual keyword bids up or down at each auction based on conversion likelihood — and Google removed it for all Search and Display campaigns on August 31, 2026, migrating all accounts to plain Manual CPC without any visible alert.

eCPC was a “light touch” automation. You set a maximum CPC at the keyword level, and Google’s algorithm raised that bid by up to 30% when it predicted a conversion was likely, or lowered it otherwise. Critically, eCPC required no conversion volume minimum. That made it the default strategy for service businesses in Malaysia and Singapore running 15–50 conversions per month — enough to benefit from algorithmic adjustment, but not enough to qualify for stable Target CPA or Target ROAS bidding.

The enhanced CPC sunset unfolded in stages: Google removed eCPC from Shopping in October 2023, barred new Search and Display eCPC campaigns on March 31, 2025, and banned all new eCPC campaigns from July 15, 2026. On August 31, 2026, all remaining eCPC campaigns were auto-migrated — confirmed by Affiliate Times, September 13, 2026. Google changed the bid strategy label to “Manual CPC,” preserved existing max CPC bid amounts, and silently removed the auction-level adjustment layer. Campaigns kept spending. Nothing looked wrong. Most accounts do not know yet that the optimisation layer is gone.

How to Find Out If Your Campaign Was Affected

You can confirm whether your campaign was migrated by checking the Bid Strategy column in Google Ads — if it now reads “Manual CPC” on a campaign you never manually switched, the eCPC adjustment layer has been removed.

Follow this diagnostic — written for a business owner, not a PPC specialist:

1. Open Google Ads and go to the Campaigns view. Add the “Bid strategy” column if it is not visible.
2. Look for “Manual CPC” on any campaign you did not manually change. If it previously ran on Enhanced CPC, it was migrated on August 31.
3. Pull a 30-day CPA comparison. Compare August 1–31 against September 1 onward. A CPA increase of 15% or more after August 31, with no other campaign changes, points directly to the loss of the eCPC adjustment layer.
4. Check your impression share. Independent analyst data cited by Affiliate Times (September 2026) shows accounts migrated to pure Manual CPC saw an average 22% drop in impression volume. Google’s auction system appears to deprioritise Manual CPC campaigns versus Smart Bidding competitors — so you cannot simply stay on Manual CPC and expect the same results.

According to Affiliate Times (September 13, 2026), CPAs are spiking 30–60% in lead-generation verticals. Stackmatix (August 2026) identifies mid-volume accounts — 20–50 conversions per month — as the hardest hit: too large to be unaffected, too small for Smart Bidding to function stably.

“eCPC was the last guardrail keeping Google’s algo honest on campaigns where my conversion data is inherently delayed or partial. The moment it died, my insurance lead campaigns on Search went from a $28 CPA to $51 overnight. I had to rebuild three funnels from scratch in August.”

— Justin Brooke, founder of AdSkills, Affiliate Times, September 13, 2026

Verticals with delayed conversion signals — property, legal, and financial services — were hit hardest. Smart Bidding requires a continuous stream of conversions to function. When leads take days to confirm, as in property, the algorithm has nothing solid to optimise against. eCPC was the workaround for exactly this situation.

Which Bidding Strategy You Should Use Now

The right replacement depends entirely on your monthly conversion volume — below 15 conversions, stay on Manual CPC; above 30, move to Maximize Conversions or Target CPA.

• Under 15 conversions per month: Manual CPC only. Calculate Max CPC as: Target CPA × Expected Conversion Rate. Build volume before considering Smart Bidding.
• 15–30 conversions per month: Maximize Conversions without a target. Accumulate signal for 30–60 days before adding a constraint.
• 30+ conversions per month: Target CPA — set 10–20% above your actual 30-day average CPA.
• 50+ conversions per month with tracked revenue: Target ROAS, with accurate revenue values attached to each conversion action.

Google’s official documentation is unambiguous: “Effective the week of March 31, 2025 Enhanced CPC (ECPC) is no longer available for Search and Display campaigns. Campaigns that were not proactively migrated to another bid strategy prior to deprecation are now effectively using Manual CPC.” — Google Ads Help, About Enhanced CPC (ECPC).

For Malaysian and Singaporean businesses, the threshold math is stark. At RM 1,500 per month with a cost per lead of RM 150, you generate roughly 10 leads per month — below the Smart Bidding floor. If your “conversion” is a WhatsApp button click, the signal quality is lower than a form fill. Smart Bidding cannot learn from ambiguous data. Malaysian practitioner Azraina Laman captured it plainly in May 2026: “Smart Bidding tiada data untuk belajar. Manual bagi kawalan sambil kumpul data.” — Smart Bidding has no data to learn from. Manual gives control while you accumulate data.

The Workarounds If You Cannot Wait for Smart Bidding Data

Three documented workarounds replicate eCPC’s behaviour at varying complexity levels — the right one depends on whether you have developer access and how much control you need.

Option 1: Google Ads Scripts. Scripts pull real-time Quality Score, impression share, and device data, then apply bid multipliers every 15–30 minutes — approximating what eCPC did at auction level. Affiliate Times reports 15–25% CPA recovery versus raw Manual CPC when correctly implemented. Setup requires 20–40 hours of developer time. If you need managed Google Ads campaigns in Malaysia, this is the configuration level an experienced team handles for you.

Option 2: Portfolio bid strategies with tight ROAS caps. Set a portfolio Target ROAS at 40–60% above actual performance. This forces the algorithm into a conservative posture — the ROAS floor prevents aggressive volume chasing. Best for accounts with 30 or more conversions and variable conversion values.

Option 3: Segmented micro-campaigns. Break one broad campaign into tighter, intent-segmented campaigns — separating “Johor Bahru physiotherapy clinic” from “physiotherapy near me” into distinct campaigns with separate bids. Cleaner signals per segment mean faster data accumulation and more precise Manual CPC control.

These are workarounds, not permanent solutions. The sustainable path is building clean conversion data to reach the Smart Bidding threshold.

The Q3 2026 Double Disruption

At the same time eCPC was removed, Google also began auto-migrating campaigns with Automatically Created Assets and campaign-level broad match into AI Max for Search — meaning some accounts had both their bidding strategy and their ad creative changed in August without any action from the advertiser.

The enhanced CPC sunset and the AI Max migration happened concurrently, creating compounding changes that are difficult to diagnose separately. Some Malaysian and Singaporean accounts had both layers changed in the same month with no human sign-off.

Independent analysis of 250+ Search campaigns by Smarter Ecommerce (SMEC, 2026) found AI Max delivered median +13% conversions but median +16% CPA. Only 22% of campaigns came close to original ROAS targets. A documented Vyncedigital case (July 2026) showed AI Max tripling click volume while conversions fell 38% and CPL nearly doubled to USD 850 — the algorithm moved up the funnel to lower-intent searches where clicks were cheaper but buyers were absent.

The DSA (Dynamic Search Ads) sunset was pushed to February 2027 — a reprieve, not a cancellation. Microsoft Ads simultaneously made AI Max the default for all new Search campaigns in September 2026. The pattern is consistent: Google is methodically removing every middle ground between full manual control and full AI automation. Enhanced CPC was the last of those middle-ground options on Search.

What Malaysian and Singaporean Businesses Should Do This Week

The most urgent step is running the campaign audit above, checking whether your CPA has risen since August 31, and verifying that your conversion tracking is recording leads accurately — because every bidding strategy and every workaround depends on clean data going in.

1. Run the bid strategy audit. Confirm which campaigns now show Manual CPC that previously ran on Enhanced CPC.
2. Verify your conversion tracking. A WhatsApp button click that misfires on certain devices sends corrupted signals. Confirm each conversion action records accurately before making any strategy change.
3. Calculate your 30-day conversion volume. Map it to the decision table above. Know your threshold position before adjusting anything.
4. If you use an agency: Ask for the bid strategy change log and CPA trend since August 31. If they cannot produce this data, that is a significant gap in account management.
5. If you are self-managing below the 15-conversion floor: Do not let Google’s Recommendations tab push you into Smart Bidding prematurely. Those recommendations are optimised for Google’s revenue, not yours. Singapore advertisers should also note that the 9% GST on Google Ads spend, in effect since January 1, 2024, means every wasted dollar on a misconfigured campaign carries a higher real cost.

If the audit reveals your account needs hands-on restructuring, the professional path is a Google Ads audit from Xwork. For accounts consistently below the Smart Bidding threshold and needing a longer-term channel, consider building organic traffic while your Google Ads data matures.

Frequently Asked Questions

What happened to Enhanced CPC in Google Ads?

Google deprecated Enhanced CPC (eCPC) for Search and Display campaigns through a phased timeline. New eCPC campaigns were no longer permitted from July 15, 2026. All remaining eCPC campaigns were auto-migrated to Manual CPC on August 31, 2026. The enhanced CPC sunset was confirmed by Affiliate Times on September 13, 2026. Google Shopping lost eCPC in October 2023. Google confirms that campaigns not proactively migrated are now effectively using Manual CPC.

Will my Google Ads keep running after the eCPC migration?

Yes. Google did not pause campaigns during the migration. The bid strategy label changed to “Manual CPC” and existing max CPC bid amounts were preserved. However, the algorithmic bid-adjustment layer was removed. Campaigns continue spending — without the conversion-probability adjustments eCPC provided. Your CPA can rise quietly while performance appears superficially normal in the dashboard.

What should I use instead of Enhanced CPC?

Your replacement depends on monthly conversion volume. Under 15 conversions, use Manual CPC and build data first. Between 15–30, use Maximize Conversions without a target. Above 30, use Target CPA set 10–20% above your 30-day actual average. Above 50 with tracked revenue, use Target ROAS. Do not upgrade based on Google’s Recommendations tab before reaching the relevant threshold.

Is AI Max for Search a good replacement for Enhanced CPC in Malaysia?

AI Max is a separate product, not a direct eCPC replacement. Smarter Ecommerce analysis of 250+ campaigns (SMEC, 2026) found AI Max delivered median +13% conversions but median +16% CPA — more leads, at higher cost. Only 22% of campaigns met original ROAS targets. Vyncedigital (July 2026) documented AI Max tripling clicks while conversions fell 38% and CPL nearly doubled. For Malaysian SMBs with delayed signals in property or legal, AI Max carries meaningful risk without guardrails.

How can I tell if my Google Ads performance dropped because of the eCPC migration?

Check the Bid Strategy column in Campaigns view. “Manual CPC” on a campaign you did not change means it was migrated on August 31. Compare August versus September CPA — a 15%+ rise with no other changes is the signal. Also check impression share: accounts on Manual CPC are seeing an average 22% drop versus Smart Bidding competitors, per independent analyst data cited by Affiliate Times (September 2026).

My budget is small (under RM3,000/month). What bidding strategy should I use?

At RM 3,000 or below in a Malaysian service vertical, you are most likely under 15 conversions per month — below the Smart Bidding minimum. Manual CPC is correct at this stage. Calculate Max CPC as: Target CPA × Expected Conversion Rate. Fix conversion tracking first, especially if you rely on WhatsApp click events. Build volume before considering Maximize Conversions or Target CPA. Do not switch based on Google’s Recommendations tab alone.

Google is making the Ads platform structurally binary — full manual control or full AI automation, with no viable middle ground remaining. The enhanced CPC sunset removed the last hybrid option that served accounts in transition. The businesses that navigate this shift successfully are the ones with clean conversion data, a clear threshold position, and bidding decisions grounded in account performance rather than platform defaults. If your account needs a structured path forward, start with a Google Ads audit from Xwork.
