Anyone find NetSuite Sitemap generator insufficient? Integrated with some other Sitemap Generator? An agency we hired keeps on saying that our sitemaps generated by NetSuite have many problems, when we've been using it with default configuration for years.

What sort of problems are they reporting? I usually have to screen mine for recurring data issues. For instance, I will do a CTRL F (find) for ".nl" and look for items/pages with .nl in the URL - as that's a sign they are missing a URL component or other data point. These types of issues are generally "fix once, and you're good for a while" type issues, though.

Thanks @Dan Curtis, But won't those changes you mention be overwritten by NetSuite's Sitemap generator though?

It does, but since NetSuite's sitemap generator doesn't work automatically on my SiteBuilder account, and I have to run it manually, I make my edits after the generator finishes. When I find issues, I usually clear them up from within NetSuite, so that the error isn't persistent.
