Google CSE (Paid Tier)
$5 per 1,000 queries. No free tier after January 2027
Strengths
- Official Google product with direct index access
- Site-restricted search for scoped results
- Familiar JSON response format for existing implementations
- Established reliability and uptime history
Weaknesses
- January 2027 deprecation deadline creates migration uncertainty
- No AI Overview, Knowledge Graph, or People Also Ask data
- Limited to 10 results per query with basic metadata
- No multi-platform coverage (Google web only)
Third-Party SERP API (Scavio, SerpApi, Serper)
Scavio: $0.005/query. SerpApi: $50/mo (5K searches). Serper: $50/mo (50K queries basic)
Strengths
- Rich structured data: AI Overview, Knowledge Graph, PAA, local pack
- Multi-platform options (Scavio covers Google, YouTube, Amazon, etc.)
- No deprecation risk -- third-party providers evolve with Google changes
- Often price-competitive with CSE at volume
Weaknesses
- Third-party intermediary adds a dependency layer
- Response schema differs from CSE -- migration requires code changes
- Rate limits and availability vary by provider
- Some providers parse results rather than using Google APIs directly
Feature-by-feature comparison
Verdict
Upgrading to Google CSE paid makes sense only if you need site-restricted search and want to delay migration. For everything else, third-party SERP APIs offer richer data (AI Overview, KG, PAA), broader platform coverage, and no deprecation deadline. At the same $5/1K query price point, Scavio returns significantly more structured data per query than CSE. Start migration now rather than waiting for the January 2027 deadline.
Consider Scavio instead
Scavio matches CSE's $0.005/query pricing while returning structured AI Overview, Knowledge Graph, People Also Ask, and local pack data that CSE never provided. Plus, the same API key covers YouTube, Amazon, Walmart, Reddit, and TikTok search. Free 250 credits/mo to test migration before committing.
