2. 广告位动态管理

2.1 广告位配置中心

// ad-config.ets
interface AdSlot {
  id: string;
  type: 'banner' | 'interstitial' | 'rewarded';
  defaultSize: string;
  refreshInterval: number;
  eCPMThreshold: number;
}

export const AD_SLOTS: Record<string, AdSlot> = {
  home_banner: {
    id: 'home_banner',
    type: 'banner',
    defaultSize: '728x90',
    refreshInterval: 60,
    eCPMThreshold: 2.5
  },
  pause_interstitial: {
    id: 'pause_interstitial',
    type: 'interstitial',
    defaultSize: 'fullscreen',
    refreshInterval: 300,
    eCPMThreshold: 5.0
  }
};

2.2 智能广告加载器

// ad-loader.ets
import { AdManager } from '@hw-agconnect/ads';

export class SmartAdLoader {
  private static instance: SmartAdLoader;
  private lastShownTime: Record<string, number> = {};

  static getInstance() {
    if (!this.instance) {
      this.instance = new SmartAdLoader();
    }
    return this.instance;
  }

  async loadAd(slotId: string) {
    const slot = AD_SLOTS[slotId];
    if (!slot) throw new Error('无效广告位');

    // 频次控制检查
    if (!this.checkFrequency(slotId)) return null;

    // 获取最佳广告源
    const ad = await this.selectBestAd(slot);
    this.lastShownTime[slotId] = Date.now();
    
    return ad;
  }

  private checkFrequency(slotId: string): boolean {
    const lastTime = this.lastShownTime[slotId] || 0;
    const interval = AD_SLOTS[slotId].refreshInterval * 1000;
    return Date.now() - lastTime > interval;
  }

  private async selectBestAd(slot: AdSlot) {
    const candidates = await AdManager.getAvailableAds({
      format: slot.type,
      minECPM: slot.eCPMThreshold
    });

    return candidates.sort((a, b) => 
      b.eCPM * b.fillRate - a.eCPM * a.fillRate
    )[0];
  }
}

3. 场景化广告策略

3.1 用户行为适配

// context-aware.ets
export function getContextualAd(user: UserProfile) {
  const context = UserBehaviorAnalyzer.getCurrentContext();
  
  switch (context) {
    case 'browsing':
      return SmartAdLoader.getInstance().loadAd('home_banner');
    case 'pause':
      return SmartAdLoader.getInstance().loadAd('pause_interstitial');
    case 'achievement':
      return SmartAdLoader.getInstance().loadAd('rewarded_video');
    default:
      return null;
  }
}

3.2 内容敏感匹配

// content-matching.ets
export async function getContentRelevantAd(content: string) {
  const keywords = NLP.extractKeywords(content);
  const ads = await AdManager.getAdsByKeywords(keywords);
  
  return ads.sort((a, b) => 
    b.relevanceScore - a.relevanceScore
  )[0];
}

4. 收益优化技术

4.1 实时竞价引擎

// realtime-bidding.ets
export async function runBidding(slotId: string) {
  const slot = AD_SLOTS[slotId];
  const bidders = await AdNetwork.getBidders();
  
  const bids = await Promise.all(
    bidders.map(async bidder => ({
      bidder: bidder.name,
      bid: await bidder.getBid(slot),
      ad: await bidder.getAdCreative(slot)
    }))
  );
  
  return bids.sort((a, b) => b.bid - a.bid)[0];
}

4.2 广告分层缓存

// ad-cache.ets
export class AdCache {
  private static cache: Map<string, Ad> = new Map();
  private static lastRefresh: number = 0;

  static async getAd(slotId: string) {
    if (this.shouldRefresh()) {
      await this.refreshCache();
    }
    return this.cache.get(slotId);
  }

  private static shouldRefresh(): boolean {
    return Date.now() - this.lastRefresh > 5 * 60 * 1000; // 5分钟刷新
  }

  private static async refreshCache() {
    const slots = Object.keys(AD_SLOTS);
    await Promise.all(slots.map(async slot => {
      const ad = await SmartAdLoader.getInstance().loadAd(slot);
      this.cache.set(slot, ad);
    }));
    this.lastRefresh = Date.now();
  }
}

5. 用户体验平衡

5.1 疲劳度控制

// fatigue-control.ets
export class AdFatigueManager {
  private static counters: Record<string, number> = {};

  static shouldShowAd(userId: string, slotId: string): boolean {
    const key = `${userId}_${slotId}`;
    const count = this.counters[key] || 0;
    const limit = AD_SLOTS[slotId]?.dailyLimit || 5;
    
    return count < limit;
  }

  static recordImpression(userId: string, slotId: string) {
    const key = `${userId}_${slotId}`;
    this.counters[key] = (this.counters[key] || 0) + 1;
  }
}

5.2 非侵入式布局

// non-intrusive.ets
@Component
struct SmartAdBanner {
  @Prop slotId: string;
  @State ad: Ad | null = null;

  aboutToAppear() {
    this.loadAd();
  }

  async loadAd() {
    if (AdFatigueManager.shouldShowAd(User.current.id, this.slotId)) {
      this.ad = await SmartAdLoader.getInstance().loadAd(this.slotId);
    }
  }

  build() {
    Column() {
      if (this.ad) {
        AdView(this.ad)
          .onClick(() => {
            AdFatigueManager.recordImpression(User.current.id, this.slotId);
          })
      } else {
        PremiumContent() // 无广告时展示优质内容
      }
    }
  }
}

6. 数据分析与调优

6.1 收益仪表盘

// revenue-dashboard.ets
@Component
struct RevenueDashboard {
  @State stats: AdStats[] = [];

  aboutToAppear() {
    this.loadStats();
  }

  async loadStats() {
    this.stats = await Analytics.getAdPerformance({
      period: '7d',
      metrics: ['eCPM', 'fillRate', 'CTR']
    });
  }

  build() {
    Grid() {
      ForEach(this.stats, (stat) => {
        GridItem() {
          AdMetricCard(stat)
        }
      })
    }
  }
}

6.2 A/B测试框架

// ad-abtest.ets
export async function runAdTest(variants: AdVariant[]) {
  return ABTest.run({
    testId: 'ad_placement_optimize',
    variants,
    primaryMetric: 'ARPU',
    secondaryMetrics: ['retention']
  });
}

7. 完整工作流示例

7.1 智能广告展示流程

// ad-workflow.ets
async function showSmartAd(slotId: string) {
  // 1. 检查用户状态
  if (User.isSubscribed()) return;
  
  // 2. 验证广告位配置
  if (!AD_SLOTS[slotId]) return;
  
  // 3. 获取最佳广告
  const ad = await AdCache.getAd(slotId);
  
  // 4. 渲染广告
  if (ad) {
    renderAd(ad);
    Analytics.trackImpression(ad.id);
  }
}

7.2 收益优化策略

// optimization-strategy.ets
export async function optimizeRevenue() {
  // 1. 识别高价值广告位
  const topSlots = await Analytics.getTopPerformingSlots();
  
  // 2. 调整竞价参数
  topSlots.forEach(slot => {
    AD_SLOTS[slot.id].eCPMThreshold *= 1.2;
  });
  
  // 3. 更新缓存
  await AdCache.refreshAll();
}

8. 关键性能指标

指标优化目标测量方法
eCPM提升20%+广告平台报表
填充率>90%请求/返回量统计
CTR>1.5%点击/展示量计算
用户留存率下降<5%日活/周活对比

9. 高级优化技巧

9.1 动态定价算法

// dynamic-pricing.ets
export function calculateDynamicECPM(slotId: string) {
  const base = AD_SLOTS[slotId].eCPMThreshold;
  const factors = {
    time: TimeUtil.isPeakHour() ? 1.3 : 1.0,
    user: User.isHighValue() ? 1.5 : 1.0,
    content: Content.isPremium() ? 1.2 : 1.0
  };
  
  return base * Object.values(factors).reduce((a, b) => a * b);
}

9.2 广告网络熔断

// circuit-breaker.ets
export class AdNetworkBreaker {
  private static failures: Record<string, number> = {};
  
  static shouldRequest(network: string): boolean {
    const failures = this.failures[network] || 0;
    return failures < 3; // 连续失败3次则熔断
  }
  
  static recordFailure(network: string) {
    this.failures[network] = (this.failures[network] || 0) + 1;
    setTimeout(() => {
      this.failures[network] = 0; // 30分钟后重置
    }, 30 * 60 * 1000);
  }
}
