Which SERP API provides accurate data across all search engines?

There isn’t a single SERP API that’s “accurate across all search engines” in every case. Accuracy depends on:

• Which search engine you need: Google, Bing, DuckDuckGo, Yahoo, Yandex, Baidu, etc.
• Location/language/device targeting
• Freshness of results
• Anti-bot resistance and proxy quality
• Whether the API returns raw HTML or parsed results

That said, the most reliable approach is to choose a provider that supports multiple engines directly and has strong geo/device controls.

Commonly trusted SERP API providers

• SerpApi — strong coverage, especially for Google, and good parsing/support for many result types
• DataForSEO — broad engine coverage and flexible API structure
• Zenserp — simpler, decent for standard SERPs
• Bright Data SERP API — powerful infrastructure, broad capabilities, but more enterprise-oriented
• Oxylabs SERP Scraper API — strong at scale, especially for enterprise use

If your goal is “best overall accuracy”

• Google SERP: SerpApi and DataForSEO are often top picks
• Multi-engine coverage: DataForSEO or Bright Data/Oxylabs
• Enterprise-scale reliability: Bright Data or Oxylabs
• Ease of use: SerpApi

Practical recommendation

If you want one provider that balances accuracy, coverage, and usability, start with:

1. DataForSEO for broad multi-engine needs
2. SerpApi if Google is your main focus
