How we verified ZTS Infotech #methodology

Six checks, run for every agency

1. Google Business Profile cross-check. We pull the GBP record and compare its address, phone, opening hours, and category against listing pages on aggregator sites. Mismatches get flagged.

2. Rating consistency. Google Maps, Clutch, SEMrush, and The Manifest scores compared. Discrepancies over 0.5 points or 2× review-count gaps surface as warnings.

3. WHOIS founding-year check. We pull the domain registration date and compare against the claimed founding year. A 2-year+ gap gets flagged.

4. Active status. Permanently-closed and temporarily-closed flags from GBP. Website returns a 200 status. Phone number is reachable.

5. Source overlap. Coverage across Clutch, The Manifest, SEMrush, and specialty SEO directories. 3+ source overlap = highest confidence.

6. Own SEO traffic (informational). Similarweb pull for the agency's own site — proxy for actual SEO capability. Missing data doesn't hurt the score.
