Use Cases

Competitor Ad Research

Analyze competitor Google Ads campaigns:

async function analyzeCompetitor(domain) {
  const { advertiser, ads } = await getCompanyAds(domain);
  
  return {
    company: advertiser.name,
    totalAds: advertiser.totalAds,
    formats: countFormats(ads),
    regions: [...new Set(ads.flatMap(a => a.regions))],
    recentAds: ads.filter(a => 
      new Date(a.lastShown) > new Date(Date.now() - 7 * 24 * 60 * 60 * 1000)
    ).length
  };
}

function countFormats(ads) {
  const formats = {};
  ads.forEach(ad => {
    formats[ad.format] = (formats[ad.format] || 0) + 1;
  });
  return formats;
}

Display Ad Analysis

Study display ad creative:

async function analyzeDisplayAds(domain) {
  const { ads } = await getCompanyAds(domain);
  
  const displayAds = ads.filter(a => a.format === 'display');
  
  // Group by size
  const bySizes = {};
  displayAds.forEach(ad => {
    bySizes[ad.size] = (bySizes[ad.size] || 0) + 1;
  });
  
  return {
    totalDisplayAds: displayAds.length,
    sizes: bySizes,
    mostCommonSize: Object.entries(bySizes)
      .sort((a, b) => b[1] - a[1])[0][0]
  };
}

Geographic Targeting

Analyze where competitors advertise:

async function analyzeRegions(competitors) {
  const regionData = {};
  
  for (const domain of competitors) {
    const { ads } = await getCompanyAds(domain);
    
    const regions = {};
    ads.forEach(ad => {
      ad.regions.forEach(r => {
        regions[r] = (regions[r] || 0) + 1;
      });
    });
    
    regionData[domain] = regions;
  }
  
  return regionData;
}

Campaign Timeline

Track when competitors run campaigns:

async function trackCampaignTimeline(domain) {
  const { ads } = await getCompanyAds(domain);
  
  const timeline = ads.map(ad => ({
    id: ad.id,
    startDate: ad.firstShown,
    endDate: ad.lastShown,
    durationDays: Math.ceil(
      (new Date(ad.lastShown) - new Date(ad.firstShown)) / (1000 * 60 * 60 * 24)
    )
  }));
  
  // Group by month
  const byMonth = {};
  timeline.forEach(ad => {
    const month = ad.startDate.substring(0, 7);
    byMonth[month] = (byMonth[month] || 0) + 1;
  });
  
  return { timeline, byMonth };
}

Landing Page Analysis

Study where ads drive traffic:

async function analyzeLandingPages(domain) {
  const { ads } = await getCompanyAds(domain);
  
  const landingPages = {};
  ads.forEach(ad => {
    const path = new URL(ad.targetUrl).pathname;
    landingPages[path] = (landingPages[path] || 0) + 1;
  });
  
  const topPages = Object.entries(landingPages)
    .sort((a, b) => b[1] - a[1])
    .slice(0, 10);
  
  return {
    uniquePages: Object.keys(landingPages).length,
    topPages
  };
}

Combining with Other Sources

Cross-reference with other ad libraries:

async function fullAdAudit(company) {
  // Get ads from all platforms
  const [googleAds, facebookAds, linkedInAds] = await Promise.all([
    getGoogleAds(company.domain),
    getFacebookAds(company.name),
    getLinkedInAds(company.name)
  ]);
  
  return {
    google: {
      total: googleAds.ads.length,
      formats: countFormats(googleAds.ads)
    },
    facebook: {
      total: facebookAds.ads.length,
      platforms: countPlatforms(facebookAds.ads)
    },
    linkedin: {
      total: linkedInAds.ads.length
    },
    totalAcrossAll: googleAds.ads.length + facebookAds.ads.length + linkedInAds.ads.length
  };
