]);
return {
google: findPosition(google, domain),
bing: findPosition(bing, domain),
coverage: calculateCoverage(google, bing)
};
}
// Complete market visibility
2. AI Training Data
def collect_diverse_data(keywords):
"""Collect from both engines for AI training"""
dataset = []
for keyword in keywords:
for engine in ['google', 'bing']:
results = client.search(q=keyword, engine=engine)
dataset.extend(parse_results(results, engine))
return dataset
# Avoid single-engine bias
# More diverse training data
3. Market Research
async function analyzeMarket(industry) {
const queries = generateQueries(industry);
const insights = {
google: {},
bing: {},
differences: []
};
for (const query of queries) {
const [g, b] = await Promise.all([

// Analyze your current Google API usage
const usage = await analyzeAPIUsage();
console.log(`Monthly searches: ${usage.total}`);
console.log(`Cost: $${usage.cost}`);
Step 2: Test Bing Results
// Compare results for your key queries
const testQueries = ['query1', 'query2', 'query3'];
for (const query of testQueries) {
const [google, bing] = await Promise.all([
serppost.search({ q: query, engine: 'google' }),
serppost.search({ q: query, engine: 'bing' })
]);
console.log(`Overlap: ${calculateOverlap(google, bing)}%`);
}
Step 3: Implement Dual Tracking
async function trackBothEngines(keyword) {
return await Promise.all([
trackGoogle(keyword),
trackBing(keyword)
]);
}

visibility: data.bing.visibility
},
combined: {
avgPosition: (data.google.position + data.bing.position) / 2,
totalReach: data.google.reach + data.bing.reach
}
