Advanced Scraping Architecture

Proxy Management Framework

Modern scraping requires sophisticated proxy handling:

class ProxyManager:
    def __init__(self):
        self.proxies = []
        self.performance_metrics = {}

    def rotate_proxy(self):
        return self.get_best_performing_proxy()

    def track_performance(self, proxy, response_time, success):
        self.performance_metrics[proxy] = {
            ‘response_time‘: response_time,
            ‘success_rate‘: success
        }

Rate Limiting Strategy

Optimal request patterns for major platforms:

Platform	Requests/Min	Delay (s)	Rotation Pattern
Glassdoor	20	3-5	Every 100 requests
Indeed	15	4-6	Every 80 requests
Trustpilot	25	2-4	Every 120 requests
G2	30	2-3	Every 150 requests
