How to Monitor Online Reviews with Proxies

Online reviews on Google, Yelp, Amazon, and Trustpilot directly impact brand reputation and purchasing decisions. Monitoring reviews at scale requires proxy infrastructure to access review platforms reliably across geographic regions.

**Disclaimer**: Review each platform's Terms of Service. Use official APIs (Google Places API, Yelp Fusion API) where available. This guide covers proxy configuration for legitimate monitoring.

Review Monitoring Architecture

import httpx
import time
import random
from dataclasses import dataclass

@dataclass(frozen=True) class Review: platform: str author: str rating: float text: str date: str business_name: str collected_at: str

@dataclass(frozen=True) class ReviewSummary: platform: str business: str avg_rating: float total_reviews: int recent_reviews: list[Review]

def collect_reviews( business_url: str, platform: str, proxy: str, ) -> list[Review]: """Collect reviews from a business listing.""" time.sleep(random.uniform(3.0, 8.0))

with httpx.Client(proxy=proxy, timeout=30, follow_redirects=True) as client: resp = client.get(business_url, headers={ "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36", "Accept": "text/html,application/xhtml+xml", "Accept-Encoding": "gzip, deflate, br", }) # Platform-specific review extraction return [] ```

Multi-Platform Monitoring

@dataclass(frozen=True)
class BusinessProfile:
    name: str

def monitor_all_platforms( business: BusinessProfile, proxy: str, ) -> dict[str, list[Review]]: """Monitor reviews across all platforms for a business.""" results: dict[str, list[Review]] = {} for platform, url in business.urls.items(): reviews = collect_reviews(url, platform, proxy) results = {**results, platform: reviews} time.sleep(random.uniform(5.0, 10.0)) return results ```

Sentiment Analysis Integration

@dataclass(frozen=True)
class SentimentResult:
    review_text: str
    sentiment: str  # positive, negative, neutral
    score: float

def analyze_review_sentiment(reviews: list[Review]) -> list[SentimentResult]: """Basic keyword-based sentiment analysis.""" positive_words = {"great", "excellent", "amazing", "love", "best", "wonderful", "fantastic"} negative_words = {"terrible", "awful", "worst", "horrible", "bad", "poor", "disappointing"}

results: list[SentimentResult] = [] for review in reviews: words = set(review.text.lower().split()) pos_count = len(words & positive_words) neg_count = len(words & negative_words)

if pos_count > neg_count: sentiment = "positive" score = pos_count / max(pos_count + neg_count, 1) elif neg_count > pos_count: sentiment = "negative" score = neg_count / max(pos_count + neg_count, 1) else: sentiment = "neutral" score = 0.5

found_keywords = list(words & (positive_words | negative_words)) results = [*results, SentimentResult( review_text=review.text[:100], sentiment=sentiment, score=round(score, 2), keywords=found_keywords, )] return results ```

Best Practices

1. Use residential proxies — review platforms detect and block datacenter traffic
2. Use official APIs — Google Places API, Yelp Fusion API provide authorized access
3. **5-10 second delays** between page requests
4. **Geo-target proxies** for location-specific review platforms
5. Monitor review velocity — sudden spikes may indicate fake reviews
