    The impact of latency

    Latency is the time data travels from the user’s device to the server and back. The greater the distance between the server and the user, the higher the latency. This increased round-trip time results in slower load times, which is especially noticeable for users far from the server’s location.

    Content Delivery Networks

    When a potential visitor requests access to a website, the CDN reduces latency and improves load times by sending the content from the nearest server. This approach is particularly effective for static content such as images, scripts, and stylesheets.

    The value of the CDN market is anticipated to grow to $36.5 billion by 2028, representing an increase of 10.9% a year.

    Infrastructure

    The efficiency and quality of the network infrastructure between the server and the website visitor can affect load times. This includes the number of intermediate routers, the quality of the internet backbone, and the peering arrangements between networks. Servers located in regions with robust network infrastructure, such as the US, tend to deliver content faster. As of March 2024, the US had 5,381 reported data centers, the most of all countries. Germany was a distant second with 521, and there were 514 in the UK. China, Canada, France, and Australia follow the top three.

    DNS resolution

    The Domain Name System transforms domain names into IP addresses. DNS servers closer to the user can resolve queries faster, contributing to quicker initial load times.

    Time to First Byte

    TTFB measures the time from the user’s initial request to the moment the first byte of data is received from the server. A server closer to the user generally has a lower TTFB, resulting in a quicker start to page loading. For example, if you choose web hosting in Canada, your site will load quickly for Canadian visitors.

    A server located near the users improves load times, reducing bounce rates and increasing the time users spend on the site. Both metrics are critical to SEO, as search engines interpret higher engagement as a sign of quality content.

    Crawl speed

    Search engines regularly crawl websites to index content. If the server is located far from the search engine’s data centers, it can slow down the crawling process. Faster servers facilitate quicker and more efficient crawling, ensuring that content is indexed promptly.

    Bandwidth

    The available bandwidth between the server and the user can affect how quickly large files are transferred. While bandwidth is not directly related to server location, the paths between geographically distant points can have varying throughput capabilities, potentially throttling speeds.

    Network speed

    Traffic congestion on networks, particularly on international or intercontinental links, can slow down data transfer rates. Servers located closer to most of the website’s users are less likely to experience such bottlenecks.

    In some cases, data needs to travel through continents to reach its destinations. Countries with more internet exchange points can deal with local traffic better. Running these very long fiber optic cables in large regions is expensive. Fewer cables can suffice in more sparsely populated countries because the bandwidth per fiber strand is higher. Smaller, less dense countries can have faster and cheaper internet connections.

    As of March 2024, Qatar had the fastest mobile internet with 313.30 Mbps download speed and 27.53 Mbps upload speed. Singapore had the highest fixed broadband speed: 284.13 Mbps for downloads and 229.80 Mbps for uploads.

    Final thoughts

    Server location is critical in determining website load times due to its influence on latency, network quality, and data transfer speeds. Performance improves when servers are close to the user base, or CDNs are used. CDNs can also enhance SEO outcomes.
