Many people expect a higher budget to show their ads to more people, but the system sometimes reacts differently. When you increase the amount too quickly, the ad platform may push your ad to a larger group that is less interested, which can reduce performance. The system also enters a learning stage again, meaning it needs time to test new groups before it improves. If the ad itself is not strong enough, a bigger budget only spreads the weakness faster. Making small budget changes usually keeps the ad stable. What do you think?
