Okay, so I keep seeing these threads about scraping Google with SEO tools and the advice is always 'get residential proxies'. The data tells a different story. For most rank trackers and keyword scrapers, a well-rotated datacenter proxy pool with the right request timing will get you 90% of the results for 20% of the cost of residentials. The trick isn't the IP type, it's how the tool integrates with the proxy's rotation. If your tool just dumps a proxy list into its settings, you're gonna have a bad time. You need session persistence for multi-step queries. Set up a simple test. Run your tool for 24 hours with a small, clean datacenter pool, then again with a residential pool from the same provider. Compare the success rate and the actual data quality, not just the raw 'requests completed' number. I did this with Ahrefs and SEMrush API pulls via a custom setup. The residentials had a 2% higher success rate but cost 5x more. That math doesn't work for scaling. The real issue is most tools' proxy integration is an afterthought, so you're fighting their bad architecture. What's the one SEO tool you use where the proxy setup actually makes sense and doesn't feel like it was coded in 2010?
