Our web site is managed by a 3rd party provider, so every time something changes or needs to be added, we get hit with a charge. That's where you experts come into play!
There is a sitemap.html file on our page. My understanding is that html is for humans (obvious), but xml is better for robots. Is that true? Can someone tell me if we should have both?
If there is a sitemap.xml file already on there, how would I tell? (I don't want to ask our vendor if it's already there. I want to at least LOOK like I know what I'm talking about).
