How Will Changing IP Addresses Impact SEO?

Never has something so simple as a string of numbers inflicted as much fear and confusion as IP addresses. Add SEO complications into the mix and you've got some very frustrated webmasters.

IP addresses are a little complicated "“ they're hardworking things after all. But there's no need to fear them. In this blog post, we'll explain what IP addresses are and what you can expect if you decide to change yours. Spoiler alert: it's a lot simpler than you'd think!

Firstly, What Is an IP Address?

Every machine connected to the internet "“ including your personal computers and the machines that store website data (servers) "“ has a unique IP address. An IP (Internet Protocol) address is a string of numbers that acts as an identifier for all devices. It's essentially a code that allows all machines (regardless of location) to 'talk' to each other via the internet.

An IP address consists of four numbers (of one to three digits), separated by a single dot. Each of the numbers can range from 0 to 255, so an IP address might look like this:

23.135.0.206

IP addresses are the single most important thing in technology today. Without them, we simply would not be able to use the internet. IPAddress explains further:

"This innocuous-looking group of four numbers is the key that empowers you and me to send and retrieve data over our internet connections, ensuring that our messages, as well as our requests for data, will reach their correct internet destinations. Without this numeric protocol, sending and receiving data over the World Wide Web would be impossible."

Will Changing IP Address Impact My Website's SEO?

Websites also have IP addresses, assigned by the server on which they are stored. If you move your website to a new server (also known as a hosting service) the IP address of your site will change. This puts many people off making the move because they fear that such a drastic change will have a huge impact on their website's SEO. All that hard work optimizing their website undone in one fell swoop.

But are these concerns legitimate or is this another myth borne from Google's notorious secrecy? Well, you'll be pleased to hear that for the most part there's little to worry about. According to our research, the SEO impact of changing IP addresses is minimal.

LeadQual, a US-dbased marketing agency, recently moved their website to a new hosting service. They were interested in the impact of such a move on SEO and so carefully monitored their rankings for six weeks after the deed was done. They noticed no decline in their rankings during that period. In fact, LeadQual claim their rankings actually improved ever so slightly.

Many other word-of-mouth reports suggest similar stories. Rankings were either unaffected or slightly improved by moving to a faster server.

Of course, as with most things there are a few possible exceptions, such as geolocation and server 'quality'. The location of the new server is especially important "“ if, for example, you are targeting an American audience, it is advisable to use an American server. As for the quality of a server, if it is especially slow or you move to a blacklisted neighborhood, you may notice a drop in your rankings.
