Summary

Fix title and meta description for docs.supadata.ai/api-reference/introduction page.

Problem

Current SERP title: "Introduction - Supadata Docs" — too generic.

• "supadata" → pos 1.0 → 763 impressions → 0.1% CTR
• "supadata api" → pos 1.0 → 483 impressions → 0.2% CTR
• Total: 2,712 impressions at pos 2.1 with only 7 clicks (0.3% CTR)

Change

api-reference/introduction.mdx frontmatter:

# Before
title: "Introduction"
description: "Supadata API Reference"

# After
title: 'API Reference'
og:title: 'Supadata REST API Reference — Authentication, Endpoints & Rate Limits'
description: 'Complete Supadata REST API reference. YouTube transcripts, web scraping, metadata extraction. API key auth. Base URL: https://api.supadata.ai/v1'

Expected Impact

CTR 0.3% → 1.5-2% = +33-47 clicks/month
