Speed is a very important consideration for visitors to your website. In the early days of the internet, web pages were tiny, reflecting the slower internet connections of the day.
As technology has marched on and increased our access speeds, websites have grown more complex and feature more media, resulting in much larger web pages to download. On the flip side of this, many visitors are using mobile devices to access the web and typically do not boast broadband speeds when out and about, so you must bear these visitors in mind too. Remember that Google’s algorithms favour faster loading sites and rank them higher.
