Share math that usually surprises people. US search share (all devices):
- Google: ~58%
- Bing + Copilot + ChatGPT Search (all Bing-index): ~15-20%
- Apple Maps / Siri for local queries on iPhone (which is ~60% of US smartphones): roughly 20-25% of all US local-intent queries start here and never touch Google
- Yelp: ~5% of search but much higher share in home services, restaurants, dental, legal, auto — where it can drive 20-30% of call volume
If you only own Google, you're missing roughly 40-45% of where US consumers find local businesses.
I just shipped four tools that cover the full matrix:
- GBP + Review Signal Audit — Google Business Profile parity signals
- Apple Business Connect Audit — 24-signal checklist for Apple Maps + Siri
- Yelp Business Profile Audit — 16-signal public Yelp profile scan
- Bing Places + Bing Search Audit — 14 signals including IndexNow + Copilot crawler allow-list
Here's how each one differs and what matters.
Google (GBP)
The big one. Primary signals: LocalBusiness schema narrow subtype, aggregateRating + reviewCount in schema, hours parity between your site and your GBP, review platforms linked from your site, "leave a review" CTA, photo gallery signal, services mirror, review-response cadence (within 48 hours for 1-3 star), Google Posts cadence (every 7 days).
The common GBP failure mode for most SMBs is cadence, not setup. People do all 16 static signals correctly and then let the profile go stale for three months. Google reads that as a dormant business and drops relevance.
Apple Business Connect
Apple Maps runs in every iPhone. Siri pulls from it. The Look Around feature is Apple's equivalent of Street View. Most SMBs under-invest here because Apple Business Connect is less publicized than GBP.
Apple-specific signals that GBP doesn't need:
- Action Items — Order, Menu, Reserve, Gift Card, Tipping. Each triggers a native iOS handoff to the merchant's app or web form.
- Showcases — Apple's version of GBP Posts with a date-bounded window.
- Indoor Maps — for venues > 10,000 sq ft.
- Look Around imagery — if your storefront changed, request updated imagery.
- Apple Search Ads placement within Maps — paid lift, optional.
- Apple Wallet Gift Cards — native iOS checkout.
Apple also penalizes keyword-stuffed business names more aggressively than Google. "Joe's Plumbing - Emergency 24/7 - Licensed Bonded Insured - Best Plumber Denver" will get flagged.
Yelp
Yelp still drives meaningful traffic in:
- Home services (plumbing, electrical, HVAC, roofing)
- Restaurants
- Dental, medical, chiropractic
- Legal
- Auto repair
- Personal care (salons, spas, tattoo, massage)
Yelp's filtering algorithm ("Auto-Recommendation Software") suppresses reviews from new accounts. This means the compliant way to earn reviews is to point customers to your Yelp listing without demanding a rating — and to count on reviews from established Yelp users being weighted more heavily than reviews from new accounts.
Claim status is the first gate. An unclaimed profile can't edit info, upload photos, or reply to reviews. Photo count is the second biggest signal. The response-time badge ("Responds in a few hours") is the third. Yelp Ads come up in every conversation with a new user — my advice is to verify organic signals are above vertical-median before paying for placement.
Bing
Bing is the sleeper. Here's why it matters in 2026:
- Bing indexes ~15% of US search traffic directly.
- Microsoft Copilot uses Bing as its retrieval backbone.
- ChatGPT Search uses Bing's index for web answers.
- DuckDuckGo sources most results from Bing.
- Yahoo uses Bing results.
When you invest in Bing, you're investing in appearing in AI answers from Microsoft and OpenAI at the same time. The specific signals:
Crawlability. Make sure robots.txt doesn't block Bingbot. Make sure your CDN (Cloudflare, Akamai) doesn't block Bingbot at the WAF layer — some default configurations do.
Bing Webmaster Tools. Claim at bing.com/webmasters. Verify via meta, DNS TXT, or file upload. Submit sitemap.xml. This is the equivalent of Google Search Console and it's free.
Bing Places. Claim at bingplaces.com. Fastest path: import from your verified Google Business Profile — Bing reads 90%+ of the fields.
IndexNow. Bing's fast-indexing protocol (also used by Yandex and Seznam). Publish a key file at /<key>.txt then POST changed URLs to api.indexnow.org after each deploy. Indexing happens within minutes instead of weeks.
ai.txt allow-list. Include OAI-SearchBot (ChatGPT Search), MSCopilot (Microsoft Copilot), ChatGPT-User. Most SMBs blanket-block AI crawlers in ai.txt and then wonder why they never appear in AI answers.
The cross-platform NAP consistency layer
One thing every platform punishes: inconsistent name, address, phone (NAP). If your GBP says "Smith Plumbing LLC" and your Yelp says "Smith Plumbing Inc" and your Apple Business says "Joe Smith Plumbing" and your Bing Places says "Smith Plumbing — Denver", each platform's confidence in your entity drops independently.
Run the NAP Consistency tool on your homepage, contact page, and footer. Then cross-check each platform listing against the single canonical NAP.
The 90-day setup plan
If you're starting from zero on platforms 2-4:
Week 1-2: Google. Run the GBP + Review Signal Audit. Fix every fail. Publish /accessibility/. Start the review-response cadence.
Week 3-4: Apple. Claim Apple Business Connect. Import what you can from GBP. Fill every Apple-specific field (Action Items, Showcases, Attributes). Run the Apple Business Audit monthly.
Week 5-6: Yelp. Claim the Yelp listing. Upload 20 photos. Enable Request-a-Quote if relevant. Start reply-to-reviews discipline. Run the Yelp Audit monthly.
Week 7-8: Bing. Claim Bing Webmaster Tools + Bing Places. Add IndexNow to the deploy pipeline. Verify bingbot isn't blocked at the CDN. Run the Bing Places Audit monthly.
Week 9-12: Cross-platform review momentum. The signals compound. Reviews on Google help; reviews on Yelp help separately; Apple Maps pulls in Yelp reviews automatically. A consistent cadence of 1-2 reviews per week across platforms is the realistic steady state for a 40-room motel, a 3-technician HVAC shop, or a 5-dentist practice.

Vertical-specific platform weighting
Not every platform matters equally for every vertical. Rough guidance:
- Hospitality / hotels / motels: Google + Booking.com + Expedia + TripAdvisor are primary; Yelp + Apple secondary. Run the Hotel / Motel Audit.
- Restaurants: Google + Yelp + Apple + TripAdvisor + OpenTable / Resy. Run the Restaurant Audit.
- Trades (HVAC, plumbing, electrical): Google + Yelp + Angi + HomeAdvisor + Nextdoor. Apple Maps matters for iPhone users who use Siri for emergencies. Run the Trades Audit.
- Medical / dental: Google + Healthgrades + Zocdoc + Yelp. Apple Maps matters. Run the Medical Practice Audit.
- Legal: Google + Yelp + Avvo + Martindale-Hubbell + Super Lawyers. Apple matters less but is low-effort. Run the Law Firm Audit.
- Retail / ecommerce: Google + Apple + Yelp + Bing. Add Merchant Listings Audit for Shopping / Free Listings.
