Users are less intimidated by shorter, more meaningful URLs that consist of words (not lots of numbers and codes), and while Google is good at indexing even complex URL structures they consider it to be best practice to choose page URLs that are more human friendly.
That means using a web CMS which enables editors to choose their own URL, such as Umbraco, and then choosing names that are short and meaningful, and not stuffed with keywords in a vain attempt to game the Google indexing bot.
Read more about good URLs in the Google SEO starter guide.
At Carbon Six Digital we recognise the importance of good SEO to the success of so many Umbraco sites. If you'd like to talk to us about our Umbraco SEO service then give us a call.
