Enhanced CPC vs Manual CPC: What Replaced eCPC

In short: Enhanced CPC was Manual CPC plus an auction-time adjustment that nudged your bid by predicted conversion likelihood. Google wound it down for Search and Display and moved those campaigns onto plain Manual CPC, so in practice the two are now the same thing. If what you wanted was the adjustment, the current answer is Maximize Conversions.

Enhanced CPC

Legacy Google setting that raised or lowered manual bids at auction time based on conversion likelihood, now retired for Search and Display.

eCPC sat between manual and fully automated bidding, nudging your max CPC on each auction. Google wound it down and moved Search and Display campaigns onto Manual CPC, so campaigns still labeled eCPC in older exports no longer receive the adjustment. If a strategy document still references it, the current equivalent is Maximize Conversions with or without a target CPA, not a manual bid with a multiplier.

Manual CPC

You set the maximum you will pay per click at keyword or ad group level, with no automated adjustment at auction time.

Bids stay where you put them until you change them, which makes spend and position predictable but blind to auction-time signals like device, time of day, and audience. It suits tiny budgets, brand terms, and diagnostic periods when you want to isolate one variable. The mistake is staying manual on a converting account long enough that competitors bidding at auction time take the cheap inventory you cannot see.

What actually separates them.

01

eCPC never set a bid from scratch; it scaled the bid you entered, so it inherited whatever error was in your manual bidding.

02

The adjustment layer is gone on Search and Display, so a campaign labeled eCPC in an old export behaves as Manual CPC today.

03

Manual CPC uses no auction-time signals at all - the same bid enters every auction regardless of device, hour, or audience.

04

The successor to eCPC is a full Smart Bidding strategy, not a manual bid with a modifier; no supported halfway setting remains.

05

Because eCPC needed conversion tracking to function, accounts running it with broken tracking were effectively on Manual CPC the whole time.

Which one should you use?

Use Enhanced CPC when

  • Reading performance data from before the wind-down and needing to know what the strategy was doing.
  • Auditing an account plan or agency deck that still specifies eCPC as the recommendation.
  • Reconciling third-party reports that still carry the eCPC label on migrated campaigns.
  • There is nothing to configure today - it is not a live choice on Search or Display.

Use Manual CPC when

  • Very small budgets where one automated misprice is a meaningful share of spend.
  • Brand keywords where you know what a click is worth and want spend flat.
  • Diagnostic periods when you need one variable held still.
  • Campaigns with too little conversion volume for an automated strategy to learn from.

Common questions.

My campaign still says Enhanced CPC. What happened to it?

Google removed the auction-time adjustment for Search and Display and migrated those campaigns to Manual CPC. Labels can lag in exports and third-party tools, but the bid entering the auction is now the number you set, with no conversion-likelihood multiplier. Treat any comparison spanning the wind-down date carefully.

What is the closest replacement for eCPC?

Maximize Conversions without a target CPA is the nearest behavioral match: it uses conversion-likelihood signals at auction time, which is what eCPC's multiplier approximated, except it sets the whole bid rather than scaling yours. Add a target CPA later, once the campaign has steady conversion data to support one.

Was eCPC ever a good idea?

It was a reasonable bridge when advertisers wanted some auction-time intelligence without giving up bid ownership. Its weakness was structural: it could only scale whatever error already sat in your manual bids. Full Smart Bidding removes that dependency, which is a large part of why the halfway option was retired.
