I’ve yet to pick my poison, but here’s a few alternatives to Google’s Sitemap Generator:
- MS Excel for Simple Sites
- JGSitemap – a sitemap generator written in Java.
- Auditmypc.com – offers another online/Java sitemap generator.
- SoftPlus GSite Crawler – locally installed software (windows only).
- blocklayer.com – provides an online tool, just enter an URL.
- Sitemap WordPress Plugin- if you run WordPress, this plugin has been getting great reviews!
