A website's sitemap is like a map of a city, except instead of streets and buildings, it's full of pages and links. It can be helpful for visitors to find their way around a large website, but it can also be a bit of a maze. I once visited a website whose sitemap was so long and complex that it looked like a giant spider web. I spent hours trying to navigate it, but in the end, I gave up and just started clicking on random links.
