VPNs are a great way to quickly change your IP location to a different one. This is especially important when it comes to SEO. The reason for this is that when you are embarking on your own SEO campaign, you will be wanting to build a large number of links.
However, if you make all of these links from your own home IP address, the platforms that you build your links on will quickly figure out that you are making all of these accounts simply to raise your sites ranking in Google.
Generally speaking, this isn’t the safest thing to do. The reason for this is that if say Tumblr decides to delete one of your accounts, they will delete all the other ones, too. This is due to them all being on the same IP address.
The much better alternative is to use a VPN. This is a Virtual Private Network. What this does is allows you to change your IP address instantaneously. I.e. if you live in Germany, you can use it to change your IP address to one in Canada.

The benefit of this is that you can create a large number of web 2.0 sites without worrying about having them removed. It also means that in the event that one is removed, since you are using different IPs for each of them, it would mean that the others are safe. This is an excellent way to get a large number of dofollow backlinks for free for your website.

Which one should you go for?

There are a lot of VPNs that are available. Some people opt for the free option. However, I would actually suggest that you don’t do this. The reason for this is that by choosing a free one, you are running the risk of having your information sold on to other people. When you think about it, how are they able to provide such an expensive service for free? Unlike a website, a VPN cannot make money off of advertising. The only way that they can make money is to sell your data on. This then means that your information is freely available, and someone could sell this information to Google which would result in your site being slapped in the search engine rankings.
Instead, it is important to purchase a VPN instead. Even when you purchase a VPN, the provider may hand over your details. TunnelBear have said that they may hand over personal data, thereby making the privacy aspect of using a VPN redundant.

One stellar VPN that does not hand over your data is Nord. They have thousands of data centres across the world, and work on a variety of mobile and desktop platforms. Not only that, but they also allow numerous people in the same household to use the connection at the same time. They never slow the connections down when doing this and there is no bandwidth restrictions.
An even better piece of news is that they don’t prohibit Peer to Peer traffic, meaning that you can torrent with them if you so wish. It also works well with Kodi.
