Microsoft Advertising removes Max CPC from new campaigns starting October 1
Non portfolio campaigns created after October 1, 2026 will not carry a maximum cost per click field. Existing campaigns, portfolio bid strategies, Target Impression Share and Enhanced CPC are unaffected. Microsoft cites the ceiling getting in the way of automated bidding.
One more manual control closes
Per a Search Engine Journal report dated August 20, 2026, Microsoft Advertising is removing the Max CPC field from the setup flow for new non portfolio campaigns. The change takes effect on October 1, 2026.
Search Engine Land confirmed the news the same day and described it as advertisers losing the manual cost per click safeguard on new campaigns.
Max CPC was the field that set a ceiling on what would be paid per click even while automated bid strategies were running. Many advertisers used it as a safety brake.
What is covered and what is not
Per Search Engine Journal, the change covers new campaigns created after October 1 using Target CPA, Target ROAS, Maximize Conversions, Maximize Conversion Value and Maximize Clicks.
What stays outside the scope is equally clear. Existing campaigns created before October 1 keep their Max CPC setting. Portfolio bid strategies continue to support Max CPC on both new and existing campaigns. Target Impression Share and Enhanced CPC are unaffected.
Microsoft's reasoning is reported like this: Max CPC can interfere with the automated bidding system even when the ceiling is set above the campaign's average cost per click. Per the publications, the company says this can override stated performance goals and lead to spend pacing irregularities.
Microsoft's recommendation is to manage performance through parameters tied directly to outcomes: budgets, Target CPA and Target ROAS goals, conversion value rules and seasonality adjustments where needed.
Per the Search Engine Journal note, accurate conversion tracking and realistic performance targets become even more important without Max CPC. Search Engine Land adds that the change reduces advertiser flexibility during peak periods such as the holidays.
With the brake gone, measurement is the only safety left
The assessment in this section is ours. Max CPC was in practice the answer to a lack of trust: the advertiser set a ceiling because they did not fully trust automated bidding. The platform argument has been the same for years: that ceiling stops the system bidding high at the right moment and worsens the total result.
Both sides are partly right. In an account with correct conversion measurement and enough data flowing, a ceiling really is an obstacle. In an account with broken measurement, the ceiling is the last safety against uncontrolled spend. This change hits the second group harder.
The second point is control moving rather than disappearing. What remains is budget, target values and the quality of conversion data. Control leaves the bid level and moves to the measurement level. That is an advantage for agencies and businesses that set measurement up properly, and a hidden risk for those that do not.
Third, the direction of the industry. This is not an isolated decision; we have seen movement along the same line for weeks. Language targeting being removed from Google Ads also meant fewer settings in the advertiser's hands. Platforms keep offering fewer dials and more goals.
Fourth, timing. The change starts on October 1 and affects only new campaigns. Advertisers who want to keep their current structures have campaigns created before that date carrying the old behaviour for a while. That is better read as time gained for the transition than as an escape route.
What it means for businesses in Türkiye
The assessment below is not in the sources, it is our reading. The reports state no Türkiye specific exception.
Microsoft Advertising usage here is limited compared with Google Ads. The importance of this news sits in the direction rather than the single platform. The same logic is being applied on the Google side, and most advertisers in Türkiye stand exactly at the weak point of this shift: accounts with missing or incorrectly configured conversion measurement.
Because of currency and cost pressure, setting a per click ceiling is a common reflex here. When that reflex disappears, spend control rests entirely on budgets and targets. It is worth rethinking whether your daily budget really is the acceptable upper limit.
Three practical steps. First, verify your conversion tracking and conversion values; a system bidding toward a goal accelerates in the wrong direction when fed the wrong value. Second, declare seasonality and campaign periods through settings in advance rather than intervening afterwards. Third, if campaigns in your account lean on Max CPC, review them before October 1 and decide what replaces which control.
A measurement note too: do not treat a rise in cost per click as a bad signal on its own. What matters is the cost and return of a conversion, not the cost of a click. Those two numbers can diverge once the ceiling is gone.
The UNALSOFT take
On the advertising management side we read changes like this as confirmation of our order of work rather than a list of losses. Measurement first, bidding second. If conversions are not counted correctly in an account, the result is left to chance no matter how many manual dials you hold; if measurement is correct, fewer dials is usually not a loss. Even so we do not move to automation in one step: we test the new structure on a limited set of campaigns and read the result together with revenue and profitability. Giving up control and moving control to the right place are different things.
