Extracting content from a website is never easy. The proxy plays an important role in web scraping. That's why you need to choose which proxies you want to use and which proxies you need, dedicated or shared proxy.
Here is a quick selection of the best proxy providers with some advice to help you choose the right one for you.
What is a Proxy?
A proxy is a computer or server that acts as an intermediary between the browser and the Internet. If there is no proxy, your request for connection to the site www.website.com will be sent directly to the server of this site.
But, with a proxy server, your request will first be sent to the server that acts as an intermediary, which is the proxy server.
Why use proxies for web scraping?
Besides the fact that a proxy can help you improve security, it is also used to block IP addresses. Therefore, by using a proxy for scraping, the target site cannot recognize your IP address.
By using a proxy to hide the hardware's IP address, the target site will not be able to track the source of the scan. Otherwise, your identity will be disclosed and you could be sued if you misuse web scraping.
The second reason to use a proxy is to exceed the connection limit.
Large websites (such as e-commerce or content-rich websites) have protocols in place that detect suspicious requests, such as copying content from multiple pages.
With a proxy (or proxies), you have multiple IP addresses and you can use these IP addresses to make multiple requests. This way, each IP will not exceed the possible connection limit on the target site.
Which proxy provider to use?
Since there are hundreds of proxy providers on the network, the selection is difficult. Before making your choice, do compare their offers based on the benefits offered (such as specs and prices). To make it easier for you, here are some of the best options.

How many proxy servers do I need?
It all depends on the target website and your intentions: the number of pages it contains, the number of pages to retrieve etc.
To get an idea, limit requests to 500 per IP per hour. Most websites use this threshold. But to be safe, you need to know the connection limits of the target site.
Prefer dedicated servers to shared servers
A dedicated server is a server that only you can use. For web scraping, it is better to have multiple dedicated servers instead of multiple shared servers. It is an investment, but it is more secure for the extracted data.

- Choose your proxy provider carefully, paying attention to the advantages offered
- Carefully choose your web scraping software and integrate your proxy into it
- Choose a dedicated server, and precisely calculate the number of proxies needed to extract the content of the website, so as not to exceed the connection limit.
