Advertisers often talk about “algorithm changes” when performance becomes unstable. In reality, most delivery constraints are not sudden changes at all. They are the visible outcome of long-term internal scoring.
Across major advertising platforms, whether social, search, or short-video, the logic is remarkably similar. While names differ, the underlying systems evaluate trust, quality, stability, and risk at multiple levels.
Trust-Based Scoring: The Account-Level Foundation

On Meta platforms, advertisers often refer to this informally as a “Trust Score,” reflected in how easily accounts pass review, how tolerant the system is of creative testing, and how quickly delivery stabilizes. Google applies a similar concept through long-term account history, policy compliance records, and payment reliability. TikTok evaluates advertiser credibility through account behavior consistency, rejection patterns, and historical enforcement signals.
Across platforms, trust-based scoring typically absorbs signals such as:
• Account lifecycle stability rather than short-term performance
Once weakened, trust does not reset simply by launching new campaigns. It often follows the advertiser across structures and limits how aggressively traffic is allocated.
Quality Scoring: Beyond Creative Metrics

While platforms expose quality-related indicators in different ways, such as relevance diagnostics on Meta or quality components within Google Ads, the true evaluation is broader than any single dashboard label.
• Creative fatigue velocity
TikTok, in particular, places strong emphasis on how content integrates into the feed experience, while Meta balances engagement against downstream satisfaction. Google’s systems extend quality judgment into landing page experience and ad-to-query alignment.
The common theme is that quality is judged longitudinally, not by peak performance moments.
User Experience and Landing Page Evaluation

Modern platforms increasingly evaluate what happens after the click as part of their internal scoring models.
Google formalizes this most clearly through landing page experience and page usability signals. Meta and TikTok do not label these metrics publicly, but both heavily weigh post-click behavior, bounce rates, and page stability.
• Mismatch between ad promise and on-page content
Conversion Integrity and Event Reliability
All major platforms operate internal mechanisms to assess whether conversion data represents genuine user intent.
On Meta, this manifests through event learning stability and optimization confidence. Google evaluates conversion action consistency and attribution reliability. TikTok monitors abnormal conversion timing, clustering, and incentive abuse patterns.
• Patterns suggesting incentivized or artificial behavior
Behavioral Stability as a System Signal
Across Facebook, Google, and TikTok, stability is quietly rewarded.
While none of these actions are “violations,” they directly affect how confidently the system can optimize. Over time, unstable behavior translates into cautious delivery.
Business Model and Industry Risk Assessment

Google is explicit about this through vertical-based policy enforcement and sensitive category handling. Meta and TikTok apply similar logic through internal risk classification, particularly for finance, subscriptions, utilities, and cross-border e-commerce.
• Industry-wide regulatory exposure
Why These Scores Must Be Viewed as a System
Rethinking Optimization in a Scored Environment
Sustainable growth comes from aligning with how platforms evaluate trust, quality, and risk over time. This means advertisers need :
In today’s advertising environment, algorithms do not simply reward performance. They reward reliability.
Where a Partner Actually Makes a Difference
For many advertisers, the challenge is not understanding that these scoring systems exist , it is knowing which signals are actually limiting scale at a given moment.
This is where a service partner becomes relevant.
At Novabeyond, our work typically starts by mapping delivery constraints across layers: account history, creative behavior, post-click experience, conversion patterns, and structural change frequency. Instead of optimizing everything at once, we identify which signals are most likely capping allocation and prioritize intervention accordingly.
• Diagnosing whether delivery limitations are account-level, creative-level, or experience-driven
• Separating performance volatility caused by learning disruption from genuine demand decline
• Rebuilding scale paths that respect platform tolerance rather than triggering defensive throttling
