Let’s start with the most basic question people are usually too worried about sounding dumb to ask.
What is a sitemap?
A sitemap is simply a list of the important pages on your website that you want search engines to know about. That’s it.
It’s usually a single file that lives on your site and acts like a table of contents. It helps Google understand:
What pages exist
How your site is organized
Which pages you actually care about
You do not need to be technical to find it.
And if you don’t have one yet, that’s not a failure. It’s just a missing piece.
