Alright so after my last VPN rant got me thinking about proxies for SEO tools, specifically scraping Google without getting your IP torched the real cost isn't just the proxy itself it's the failure rate and speed that kills your data, residentials are obvious but the price per GB racks up fast if your tool is sloppy with requests been there tested that, datacenter proxies are cheap but Google sniffs them out quicker than you can say captcha, the sweet spot I found is a smaller pool of mobile 4G proxies on a rotating setup, yes the per-IP cost is higher but your success rate for SERP pulls goes way up because they look like real user phones just make sure your tool can handle the auth method most providers use user
ass not whitelists honestly if you're just starting just pay for a dedicated scraper API, building a proxy pool and managing the anti-detection is a full-time job unless you're automating at massive scale, but if you're stubborn like me and want the data yourself then mobile rotating is the only setup where my numbers made sense without burning cash on residential bandwidth for failed requests
