KML File vs. KMZ File

[RezStream8]

When should you use a KMZ file? What are the benefits to using a KMZ file as opposed to just a standalone KML file?

I'm not sure if you are referencing SEO in this post, but here's the breakdown from my experience (Several years in the GIS realm)

KMZ when you have a lot of markers in the map making the file size is large and you know the end user will use a Google product to read it.

KML if you are needing to read the file with a program outside of Google due to incompatibility issues with the KMZ format in other programs.

Thanks for the feedback! Are you saying that the KMZ file is for when you have more than one location for a particular business/domain? If you only have one business location, would a KML be ideal as it relates to local SEO exposure? We work with independent hotels. Therefore, locally speaking, what do you feel is the best strategy regarding site maps?

Sorry, I meant to respond to this days ago.  Started, but didn't finish and then it left my mind.

It sounds to me like you want to place a Google map on your site to show the location of the business?  If this is correct, I wouldn't use KML nor KMZ.  I would just use a javascript point market that represents the one location using the Google Maps API.  You can see what I mean as I have several points on one site I'm finishing up at http://www.snoshield.com/contest/christmas2012

You can also show service area like this: http://www.kcdirt.com/contact

Both of those maps use strictly JavaScript, there is no KML or KMZ on them.
