Key Takeaways for B2B & Digital Agencies

Finding 01

High Review Volume ≠ Modern Web Presence

Dozens of operators with 200 to 950+ verified 4.5★–5.0★ Google reviews still have zero website linked to their Google Business Profile, relying strictly on word-of-mouth referrals.

Finding 02

Plain HTTP & Legacy Viewports Persist

Established dental clinics, plumbers, and auto repair shops built custom HTML sites between 2010 and 2017 that now trigger browser 'Not Secure' warnings and fail mobile-first indexing.

Finding 03

WAF Filtering Eliminates Outreach Embarrassment

Naive scrapers flag Cloudflare 403/503 responses as dead websites. Excluding WAF status codes prevents agencies from sending inaccurate cold emails to protected corporate domains.
