If you go for dedicated proxies, no one else will have the same IPs as yours. You’ll minimize the risk of blocks and have full control and ownership of the browsing history, acceptability, trust, and health of your IP. Just think about the shared proxies that let several people use them at the same time. Yes, they will be cheaper, but it’s not all parties and red-wines… What if you want to target data that everybody scrapes simultaneously? With shared proxies, you’ll have more chances to get blocked, together with all the others. Especially, if you aren’t a pro just yet when it comes to proxies.
