在 Flutter 应用程序中对多个横幅使用相同的 AdMob 横幅广告单元 ID 是否会影响广告效果？

Question

我正在将 Google AdMob 横幅广告集成到我的 Flutter 应用程序中。我目前对所有横幅广告使用相同的bannerAdUnitId，但我担心这种方法是否会影响广告效果或收入。

以下是相关代码片段：

class AdManager {
  static final AdManager _instance = AdManager._internal();
  static AdManager get instance => _instance;

  AdManager._internal();

  BannerAd? normalModeBannerAd;
  BannerAd? categoriesAd;

final bannerAdUnitId =
      Platform.isAndroid ? AppSettings.androidBannerAdId : AppSettings.iosBannerAdId;

Future<void> loadCategoriesAd() async {
    bool result = await TrackingPermissionHandler.instance.checkTrackingPermission();
    if (result) {
      if (kDebugMode) {
        print('Tracking permission granted.');
      }

      categoriesAd = BannerAd(
        adUnitId: bannerAdUnitId,
        size: AdSize.banner,
        request: const AdRequest(nonPersonalizedAds: false),
        listener: BannerAdListener(
          // Called when an ad is successfully received.
          onAdLoaded: (Ad ad) {
            debugPrint('$BannerAd loaded.');
          },
          // Called when an ad request failed.
          onAdFailedToLoad: (Ad ad, LoadAdError error) {
            debugPrint('$BannerAd failedToLoad: $error');
            ad.dispose();
          },
          // Called when an ad opens an overlay that covers the screen.
          onAdOpened: (Ad ad) => debugPrint('$BannerAd onAdOpened.'),
          // Called when an ad removes an overlay that covers the screen.
          onAdClosed: (Ad ad) => debugPrint('$BannerAd onAdClosed.'),
          // Called when an ad is in the process of leaving the application.
        ),
      );

      categoriesAd?.load();
    } else {
      if (kDebugMode) {
        print('Tracking permission is not granted.');
      }
      categoriesAd = BannerAd(
        adUnitId: bannerAdUnitId,
        size: AdSize.banner,
        request: const AdRequest(nonPersonalizedAds: true),
        listener: BannerAdListener(
          // Called when an ad is successfully received.
          onAdLoaded: (Ad ad) {
            debugPrint('$BannerAd loaded.');
          },
          // Called when an ad request failed.
          onAdFailedToLoad: (Ad ad, LoadAdError error) {
            debugPrint('$BannerAd failedToLoad: $error');
            ad.dispose();
          },
          // Called when an ad opens an overlay that covers the screen.
          onAdOpened: (Ad ad) => debugPrint('$BannerAd onAdOpened.'),
          // Called when an ad removes an overlay that covers the screen.
          onAdClosed: (Ad ad) => debugPrint('$BannerAd onAdClosed.'),
          // Called when an ad is in the process of leaving the application.
        ),
      );

      categoriesAd?.load();
    }
  }

  Future<void> loadNormalModeBannerAd() async {
    bool result = await TrackingPermissionHandler.instance.checkTrackingPermission();
    if (result) {
      if (kDebugMode) {
        print('Tracking permission granted.');
      }

      // Dispose existing ad if it exists
      await disposeNormalModeBannerAd();

      normalModeBannerAd = BannerAd(
        adUnitId: bannerAdUnitId,
        size: AdSize.banner,
        request: const AdRequest(nonPersonalizedAds: false),
        listener: BannerAdListener(
          // Called when an ad is successfully received.
          onAdLoaded: (Ad ad) {
            debugPrint('$BannerAd loaded.');
          },
          // Called when an ad request failed.
          onAdFailedToLoad: (Ad ad, LoadAdError error) {
            debugPrint('$BannerAd failedToLoad: $error');
            ad.dispose();
          },
          // Called when an ad opens an overlay that covers the screen.
          onAdOpened: (Ad ad) => debugPrint('$BannerAd onAdOpened.'),
          // Called when an ad removes an overlay that covers the screen.
          onAdClosed: (Ad ad) => debugPrint('$BannerAd onAdClosed.'),
          // Called when an ad is in the process of leaving the application.
        ),
      );

      normalModeBannerAd?.load();
    } else {
      if (kDebugMode) {
        print('Tracking permission is not granted.');
      }

      // Dispose existing ad if it exists
      await disposeNormalModeBannerAd();

      normalModeBannerAd = BannerAd(
        adUnitId: bannerAdUnitId,
        size: AdSize.banner,
        request: const AdRequest(nonPersonalizedAds: true),
        listener: BannerAdListener(
          // Called when an ad is successfully received.
          onAdLoaded: (Ad ad) {
            debugPrint('$BannerAd loaded.');
          },
          // Called when an ad request failed.
          onAdFailedToLoad: (Ad ad, LoadAdError error) {
            debugPrint('$BannerAd failedToLoad: $error');
            ad.dispose();
          },
          // Called when an ad opens an overlay that covers the screen.
          onAdOpened: (Ad ad) => debugPrint('$BannerAd onAdOpened.'),
          // Called when an ad removes an overlay that covers the screen.
          onAdClosed: (Ad ad) => debugPrint('$BannerAd onAdClosed.'),
          // Called when an ad is in the process of leaving the application.
        ),
      );

      normalModeBannerAd?.load();
    }
  }
}

我是否应该为同一应用内的不同横幅广告使用不同的广告单元 ID？这会如何影响广告效果和收入？

Answer 1

在不同屏幕上使用相同的banner ID完全没有问题。如果您愿意，您可以创建另一个横幅并在不同的屏幕上加载不同的横幅 ID。拥有多个横幅可以为您提供更好的分析选择。但是，如果您在同一屏幕上多次使用同一横幅，则可能会出现错误。
