Web Scraping FAQ
Everything you need to know about scraping with proxies
What are web scraping proxies and why do I need them?+
Web scraping proxies are intermediary servers that route your scraping requests through different IP addresses. You NEED them because websites see ALL requests coming from YOUR single IP and detect "bot behavior" in seconds. Without proxies: 1 IP = 10-50 requests max before ban. With proxies: Each request comes from a DIFFERENT IP = 10,000 requests from 10,000 different people = normal traffic. Zero bans. Example: Scraping Amazon products without proxies? Banned after 20 pages. With FlashProxy rotating residential? Scrape 2.5M pages daily, zero blocks.
Which proxy type should I use for web scraping?+
Depends on your target. Wrong type = instant ban. Datacenter Proxies: Best for news sites, small e-commerce, public data. Fast (30-50ms), cheap ($0.06-0.70/GB). Cons: Many sites detect and block datacenter IPs. ISP Proxies: Best for LinkedIn, medium-protection sites. Fast (40-50ms) + trusted (residential reputation). Residential Proxies: Best for Amazon, Google, social media, strict sites. Real home ISPs, pass ALL bot detection. Cons: Slower (200-500ms), most expensive. FlashProxy Recommendation: Start with datacenter (cheapest). If getting blocked, upgrade to ISP. If still blocked, use residential. Save money where you can.
Can I use datacenter proxies for Amazon and Google?+
NO. Amazon and Google have the strictest bot detection on the internet. They maintain MASSIVE databases of datacenter IP ranges and block them instantly. What happens: First request with datacenter IP triggers CAPTCHA. Second request = IP banned. Third request = your entire ASN/subnet banned. Waste $300+ on proxies that don't work. For Amazon: MUST use residential rotating proxies. FlashProxy ATT Residential = real home ISPs. Rotate every 5-10 requests. Pass bot detection 99%+ of time. For Google SERP: MUST use residential rotating + geo-targeting. Match proxy location to search location. Scraping "New York pizza" from London IP = instant fail. Save your money: Don't even TRY datacenter on these sites. Use residential from the start.
What is proxy rotation and why is it important?+
Proxy rotation = automatically switching to a NEW IP address every few requests. CRITICAL for web scraping at scale. Without rotation: Using same IP for 1,000 requests = website detects bot pattern. Rate limits kick in. IP banned. All scrapers using that IP stop working. With rotation: Each request uses NEW IP = website sees 1,000 different users making 1 request each = normal traffic. Zero detection. Rotation frequency: Amazon/Google = every 3-10 requests. LinkedIn = every 10-20 requests. E-commerce = every 50-100 requests. News sites = every 500+ requests. FlashProxy residential: Automatic rotation. Each request gets NEW IP from pool of millions. Set it and forget it.
How many proxies do I need for web scraping?+
Depends on volume and rotation strategy. Small scale (<10K pages/day): 10-50 datacenter proxies rotating. Cost: $20-50/month. Medium scale (10K-100K pages/day): 100-500 ISP proxies or rotating residential pool. Cost: $175-625/month for unlimited bandwidth ISP. Large scale (100K-1M pages/day): Residential rotating pool (millions of IPs) + ISP for speed-critical tasks. Cost: $625-2,000/month. Enterprise (1M+ pages/day): Mix of residential (50%), ISP (30%), datacenter (20%) for optimal cost/performance. Cost: $2,000-6,900/month. FlashProxy advantage: Start small with datacenter. Scale up to ISP or residential only for sites that need it. Don't overspend on expensive proxies for easy targets.
What is the difference between rotating and sticky proxies?+
Rotating Proxies: IP changes automatically every request (or every N requests). Best for high-volume scraping where you DON'T need to maintain sessions. Use rotating for: SERP scraping, product catalog scraping, price monitoring, public data extraction. Sticky Proxies: Same IP for duration of session (5-30 minutes). Best when you NEED to maintain login state or shopping cart. Use sticky for: Scraping behind login walls, maintaining shopping carts on e-commerce, LinkedIn profile scraping (logged in), account management tasks. FlashProxy supports both: Residential = rotating by default. ISP = sticky sessions. Choose based on use case.
Why am I getting CAPTCHAs even with proxies?+
CAPTCHAs = website suspects bot. Even with proxies, you can trigger CAPTCHAs if: 1. Wrong proxy type: Using datacenter on Amazon/Google = instant CAPTCHA. Solution: Switch to residential or ISP proxies. 2. Too many requests too fast: Scraping 1000 pages in 30 seconds = bot pattern. Solution: Add random delays (2-5 seconds between requests). 3. No browser fingerprinting: Missing user-agent, headers, cookies = detected. Solution: Use headless browser (Puppeteer/Playwright) with realistic headers. 4. Not rotating enough: Using same IP for 1000 requests = detected. Solution: Rotate every 5-10 requests for strict sites. FlashProxy advantage: Our residential proxies = REAL residential IPs with clean reputation. Pass bot detection 99%+ of time when combined with proper scraping technique.
Do FlashProxy proxies work with Scrapy, Puppeteer, and Selenium?+
YES. FlashProxy works with ALL major scraping frameworks and tools. We use standard HTTP/HTTPS/SOCKS5 protocols with username:password authentication. Scrapy: Add proxy list to ROTATING_PROXY_LIST setting. Works perfectly with scrapy-rotating-proxies middleware. Puppeteer/Playwright: Pass proxy as launch argument: --proxy-server=username:password@host:port. FlashProxy tested with both. Selenium: Set proxy in ChromeOptions or FirefoxOptions. Works with both Chrome and Firefox drivers. Python requests/httpx: Pass proxy dict in session. Simple one-line configuration. Setup time: Under 5 minutes for any framework. Our docs have copy-paste code examples for all popular tools.
How much does web scraping cost with proxies?+
Cost depends on proxy type and volume. IPv6 Datacenter (cheapest): $0.06/GB. Scrape 1M pages = $50-100. Best for news sites, public data, low-protection targets. IPv4 Datacenter: $0.20-0.70/GB. Scrape 1M pages = $200-700. Good for most e-commerce, better IP reputation than IPv6. ISP Proxies (best value): $175-2,000/month unlimited bandwidth (30Mbps-1Gbps). Scrape UNLIMITED pages. Best for LinkedIn, medium-protection sites. Our most popular choice. Residential Rotating: $0.05-0.50/GB depending on volume. Scrape 1M pages = $500-5,000. Best for Amazon, Google, strict targets. Pay for what you use, data never expires. FlashProxy recommendation: Start with datacenter ($50/month). Most scrapers never need to upgrade. Only pay for expensive residential if you're actually targeting Amazon/Google/social media.
What makes FlashProxy better than other proxy providers?+
1. Speed: 40-50ms response time with GTT ISP network. Competitors = 200-800ms. Scrape 10x faster. 2. Success Rate: 99.4% success rate. Our IPs are CLEAN with good reputation. No blocked/blacklisted IPs. 3. Real ISP Proxies: 20,000+ GTT ISP IPs. Not datacenter masquerading as ISP. Real residential trust at datacenter speed. 4. Unlimited Bandwidth ISP: Most competitors charge per GB even for ISP. We offer TRUE unlimited bandwidth from $175/month. 5. Data Never Expires: Buy 100GB datacenter/residential? Use it over 1 year if you want. Competitors force monthly expiration = wasted money. 6. Mix & Match: Don't force you into one proxy type. Use datacenter for easy targets, ISP for medium, residential for hard. Optimize costs. 7. Free 5GB Trial: Test on YOUR targets before buying. Most competitors = no trial or tiny 1GB trial. We give 5GB = enough to actually test.
Can I get banned for web scraping even with proxies?+
Proxies help you AVOID bans, but you can still get banned if you scrape incorrectly. You WILL get banned if: Using wrong proxy type (datacenter on Amazon), scraping too fast (no delays), not rotating proxies, using same user-agent for all requests, ignoring robots.txt completely. You WON'T get banned if: Using correct proxy type for target, adding random delays (2-5 seconds), rotating proxies every 5-50 requests, using realistic browser headers, mimicking human behavior patterns. Is web scraping legal? Scraping public data = generally legal. Scraping behind login walls or violating ToS = can have legal issues. We're not lawyers, consult one if unsure. FlashProxy best practice: Use our proxies responsibly. Add delays. Rotate frequently. Respect rate limits. Our proxies give you the TOOLS to avoid bans, but you must use them correctly.
What is the best proxy type for scraping 1 million pages?+
Depends on target protection level. Easy targets (news, small e-commerce, public data): IPv6 Datacenter. Cost: $50-100 for 1M pages. Time: 6-12 hours with good infrastructure. Medium targets (most e-commerce, directories): IPv4 Datacenter or ISP. Cost: $175-625/month unlimited ISP is best value. Time: 8-16 hours. Hard targets (Amazon, Google, LinkedIn): Residential Rotating or ISP. Cost: $500-2,000 for residential, or $175-625/month ISP unlimited. Time: 12-24 hours. FlashProxy Pro Tip: Mix proxy types. Use datacenter for 70% of easy pages ($50), ISP for 30% of protected pages ($175/month) = scrape 1M pages for $225 total instead of $5,000 all-residential. Performance tip: Use 100-500 concurrent workers. More workers = faster scraping, but add delays to avoid detection.
How do I know if my proxies are working correctly?+
Test your proxies in 3 steps. 1. Connection Test: Make request to https://httpbin.org/ip through proxy. Should return proxy IP, not your real IP. If it returns your IP = proxy not connected. 2. Speed Test: Measure response time. Datacenter should be <50ms. ISP should be 40-50ms. Residential should be <500ms. Slower = issue with proxy or target site. 3. Target Test: Make 10-20 requests to actual target site. Check for: 200 OK responses (good), 403 Forbidden (proxy blocked), 429 Too Many Requests (rate limited), CAPTCHA challenges (bot detected). FlashProxy Dashboard: Monitor real-time proxy status, bandwidth usage, success rate, response times. If issues, contact 24/7 support.
What is the difference between HTTP and SOCKS5 proxies?+
HTTP/HTTPS Proxies: Work at application layer. Only handle HTTP/HTTPS traffic. Best for web scraping. Pros: Fast, compatible with all web scrapers, supports HTTPS. Cons: Only works for web traffic. SOCKS5 Proxies: Work at transport layer. Handle ALL traffic types (HTTP, HTTPS, FTP, etc). Best for applications that need full network access. Pros: Works with any protocol, supports UDP. Cons: Slightly slower than HTTP proxies. For web scraping: HTTP/HTTPS proxies are BEST. They're optimized for web traffic and 10-20% faster than SOCKS5 for HTTP. When to use SOCKS5: If you need to proxy non-HTTP traffic, or if you're using applications that don't support HTTP proxies (some bots, games, etc). FlashProxy supports both: All our proxies support HTTP/HTTPS/SOCKS5. ISP proxies even support UDP (rare). Use whatever works best for your setup.
Should I use shared or dedicated proxies for web scraping?+
Shared Proxies: Multiple users use same IP pool. Pros: MUCH cheaper (10x), large IP pools. Cons: IP might be used by another user = potential for being already blocked. Dedicated Proxies: Only YOU use the IP. Pros: No risk of another user getting it blocked, faster (no sharing bandwidth), better for account management. Cons: 10x more expensive, smaller IP pools. For web scraping: Shared proxies are BEST for 95% of use cases. FlashProxy shared IPs = clean reputation, large pools, 99.4% success rate. Save money. Use dedicated if: Managing valuable accounts (social media with 100K followers), need guaranteed speed (trading, sneaker bots), or if you're rate-limited and need consistent IP. FlashProxy offers both: Shared ISP from $175/month unlimited. Dedicated ISP at $2.75/IP. Most web scrapers use shared and save 90%.
