Ever wondered how SEO tools track rankings across thousands of keywords, or how price comparison sites stay updated in real-time? The answer is SERP scraping. With Google processing around 8.5 billion searches daily, there's a goldmine of data waiting to be tapped for SEO analysis, lead generation, and competitive intelligence.
But here's the catch: scraping Google at scale isn't as simple as sending a few requests. After about 100 requests, you'll likely hit a wall. That's where dedicated SERP APIs come in.
I've tested 10 leading SERP APIs to see which ones actually deliver on speed, scalability, and cost-efficiency. The results might surprise you. Some APIs completed requests in under 2 seconds, while others took over 30 seconds for the same task. And pricing? It varies wildly, from $0.00029 to $0.015 per request.
Let's break down what I found.
Before diving into individual reviews, here's my testing methodology. I evaluated each API based on five critical factors:
Scalability - How many pages can you realistically scrape per day without hitting limits?
Pricing - What's the actual cost per API call, and how does it scale with volume?
Speed - How quickly does the API return results? This directly impacts your data pipeline efficiency.
Developer Experience - Is the documentation clear? Can you integrate it without pulling your hair out?
Stability - How reliable is the service under load, and what's the company's track record?
For speed testing, I ran 50 requests with random search queries and measured average response times. Here's the Python script I used if you want to replicate these tests yourself.

Speed: 9.29 seconds average. Slower than competitors, though the 100% success rate is reassuring.
Pricing: $0.001 per request, dropping to $0.0008 at high volume. However, concurrency is limited at this price point.
Developer Experience: Straightforward documentation and easy integration.
Stability: Industry pioneer with proven reliability.
The verdict: If you prioritize 100% success rates over speed and don't mind paying a premium, Oxylabs delivers. But for time-sensitive applications, the 9+ second response time might be a dealbreaker.
Bright Data is a major player in the data collection space, offering proxies and various scraping solutions.
Speed: 5.58 seconds average. Respectable performance.
Pricing: $0.005 per request. More expensive than most alternatives, but the quality is consistent.
Developer Experience: Clear documentation and simple testing process.
Stability: Top-tier service with excellent success rates.
The verdict: You're paying for premium quality and support. If budget isn't a constraint and you value reliability above all, Bright Data won't disappoint. But for cost-conscious projects, there are cheaper alternatives that perform similarly.
Hasdata focuses specifically on search engine APIs with a dashboard that simplifies onboarding.
Speed: 3.80 seconds average. However, performance degrades with repeated requests to the same endpoint.
Pricing: $0.003 per request, dropping to $0.0004 at scale.
Developer Experience: Simple, easy-to-understand documentation.
Stability: The slowdown issue under load raises concerns about scalability.
The verdict: Good for low-to-moderate volume projects. If you're planning high-frequency scraping, the performance degradation could become problematic.
Serper provides dedicated solutions for scraping various Google products with clean API design.
Speed: 2.87 seconds average. Second-fastest in our tests.
Pricing: $0.001 per request, dropping to $0.00075 at volume. But here's the catch: if you need more than 10 results per query, they charge 2 credits, effectively doubling the cost.
Developer Experience: Clear documentation and easy integration.
Stability: Relatively new service with limited public information about the team.
The verdict: Great performance and competitive pricing for basic queries. Just watch out for the credit multiplier if you need comprehensive result sets. When you're extracting extensive search data, 👉 Scrapingdog's flexible pricing structure might offer better value without hidden multipliers.
SerpAPI offers the widest variety of Google-related APIs with a focus on speed and reliability.
Speed: 5.49 seconds average. Solid performance.
Pricing: $0.01 per request, dropping to $0.0083 at scale. Among the most expensive options tested.
Developer Experience: Very clear and concise documentation. You can start scraping within minutes.
Stability: In the market since 2016 with extensive experience in high-volume projects.
The verdict: If you need to scrape multiple Google services and price isn't a primary concern, SerpAPI's variety and reliability make it a strong contender. But for cost-sensitive projects, you'll find better value elsewhere.
Decodo leverages Smartproxy's proxy infrastructure to provide Google search API services.
Speed: 4-5 seconds based on dashboard testing.
Pricing: $0.00125 per request, dropping to $0.00095 at high volume.
Developer Experience: Simple documentation and easy integration.
Stability: Strong proxy infrastructure ensures reliable data delivery.
The verdict: Mid-range option with balanced performance and pricing. The proxy infrastructure is a plus for data quality.

Pricing: $0.00196 per request, scaling up to $0.0024 for larger packages.
Developer Experience: Clear documentation with code snippets for major languages.
Stability: Long market presence, but the SERP API performance doesn't match expectations.
The verdict: While ScraperAPI has a good reputation for general web scraping, their SERP API significantly underperforms competitors. The 33+ second response time makes it unsuitable for time-sensitive applications.
After testing all 10 APIs with identical conditions, here's what I found:
Fastest: Scrapingdog (1.83s) and Serper (2.87s) lead the pack by a considerable margin.
Mid-range: Hasdata (3.80s), Decodo (4-5s), SerpAPI (5.49s), and Bright Data (5.58s) offer respectable performance.
Slower: Apify (8.2s) and Oxylabs (9.29s) lag behind but maintain high success rates.
Slowest: ScraperAPI (33.6s) is an outlier, taking more than 10x longer than the fastest options.
For production environments where every second counts, speed matters. A 30-second delay per request adds up quickly when you're processing thousands of queries.
At first glance, pricing seems similar across providers. But volume pricing reveals stark differences:
Most economical at scale: Scrapingdog ($0.00029 per request at enterprise volume)
Mid-range: Serper ($0.00075), Oxylabs ($0.0008), Decodo ($0.00095), and most others fall between $0.001-$0.003
Premium pricing: SerpAPI ($0.0083) and Bright Data ($0.005) charge significantly more
The key insight? If you're scraping fewer than 10,000 requests monthly, pricing differences won't significantly impact your budget. But at 100,000+ requests, choosing the right API can save thousands of dollars annually.
You might be thinking: "Why pay for an API when I can scrape Google myself?" Here's the reality check.
Google blocks scrapers after roughly 100 requests. Maintaining a working scraper means constantly updating your code to bypass detection, managing proxy pools, handling CAPTCHAs, and dealing with rate limits. It's a full-time job.
APIs solve these problems:
Anonymity: Every request uses a different IP address. Your identity stays hidden, and blocks become a non-issue.
Cost efficiency: Building and maintaining scraping infrastructure costs more than API subscriptions for most use cases.
Data formats: Get parsed JSON for easy integration or raw HTML for maximum flexibility.
Customization: Many vendors offer tailored solutions for specific needs.
Production reliability: APIs are designed for stability and scale, unlike DIY solutions that require constant maintenance.
Support: Round-the-clock assistance when issues arise.
Search results are just the beginning. Google's ecosystem offers numerous data sources worth exploring:
Google AI Overviews: Monitor how AI-generated summaries affect your brand visibility and SEO strategy.
Google Maps: Extract business details, reviews, and location data for local SEO, lead generation, and market analysis.
Google News: Track news coverage, perform content analysis, and monitor brand mentions.
Google Scholar: Gather academic citations and research data.
Google Images: Collect visual content and image metadata.
Each of these requires specialized handling, but the right API can unlock valuable insights across Google's entire product suite.
After extensive testing, here's my honest take:
For speed-critical applications, Scrapingdog and Serper are your best bets. Both deliver sub-3-second response times consistently.
For budget-conscious projects at scale, Scrapingdog offers unbeatable economics, especially at higher volumes.
For enterprise needs with premium support requirements, Bright Data or Oxylabs provide rock-solid reliability despite higher costs.
For diverse scraping needs beyond Google, Apify's platform approach makes sense.
Almost every API mentioned here offers free trials. Test them in your specific environment before committing. What works for one use case might not work for another, and hands-on testing reveals nuances that specifications can't capture.
The data is out there, waiting to be collected. Choose your tool wisely, and start building.
