Slow spending is a common sign that the system hasn’t yet recorded enough trust signals from your account, campaign, or landing page. Even with creative and page changes, constant relaunches can reduce stability, making the algorithm reluctant to open up budgets. Instead, focus on optimizing a single structure, keeping pixels, events, and user behavior natural. Make sure there are no red flags like high bounce rates, creative spam, or frequent edits. Sometimes, stability and consistency are the key to overcoming trust thresholds and reactivating the expected spend rate.
