* Ask your friends and co-workers
If you noticed that your colleague can access a website that you couldn’t view using your own computer, ask him or her if she is using a proxy. If he or she does, ask him or her what proxy it is. If that proxy works for them, it will most likely work for you, too.
* Browse blogs and websites that list and evaluate proxy sites
The problem with using proxies is that many of them tend to become unavailable after some time. For this reason, you have to know other proxies that you can use in case your top choice no longer works. Because of the increasing popularity of the use of proxies, many website and blog owners now dedicate themselves to giving the latest updates on proxies. You can also get advice from them on which proxies are the best. Sign up to their mailing lists so that you can get updates through your email.
* Search for the best proxies by using your favorite search engine
Your favorite search engine is still a reliable source of information when it comes to looking for the best proxies that you can use. Typing “proxy list” “new proxies” “reliable proxies” at the search bar of the search engine will give you a list of websites that can give you more information on proxies. Some proxy sites are also included in the search engine results.
