A plain-text phone number forces mobile visitors to memorize digits, switch apps, and type manually — most abandon before dialing. Wrapping the number in tel: turns every render into a one-tap call on iOS and Android, directly converting local-search intent into booked calls. Non-E.164 hrefs (missing + or country code) fail on international roamers and some carrier dialers, silently dropping leads from the exact high-intent mobile traffic local SEO is meant to capture.
High because phone calls are the primary conversion event for most local businesses and a plain-text number blocks tap-to-call on mobile.
Wrap every rendered phone number in an <a href="tel:..."> tag using strict E.164 format in the href (display text can stay formatted). Update src/components/footer.tsx, the contact page, and any header CTA component so every instance is tappable.
<a href="tel:+15555555555">(555) 555-5555</a>
The href must contain only +, country code, and digits — no spaces, dashes, or parentheses.

Severity: high
What to look for: Find where the phone number is rendered in the UI. Check that phone number text is wrapped in an <a href="tel:..."> tag. Also verify the tel: href uses E.164 format (e.g., tel:+15555555555) even if the display text uses a different format. Check footer, contact page, and any header/CTA components.
Pass criteria: Count all phone number instances rendered in the UI. 100% of instances must be wrapped in a tel: link with a properly formatted E.164 number in the href. At least 1 phone number must be visible on the primary landing page or its layout.
Fail criteria: Phone number is displayed as plain text without a tel: link, or the tel: href is malformed (missing country code, contains spaces or formatting characters).
Skip (N/A) when: No phone number is displayed anywhere in the UI, or whole-audit N/A rule applies.
Detail on fail: Describe what was found. Example: "Phone number in footer.tsx is plain text — not wrapped in a tel: link" or "tel: href in contact/page.tsx is 'tel:555-555-5555' — missing country code, should be 'tel:+15555555555'"
Remediation: Wrap phone numbers in a tel: link in your src/components/footer.tsx:
<a href="tel:+15555555555">(555) 555-5555</a>
The href must use E.164 format -- + followed by country code followed by the number with no spaces, dashes, or parentheses.
