Scalable Sitemaps is a WordPress plugin that will provide fast, clean and efficient xml-compliant sitemaps for your website. Many sitemap and SEO plugins do not have great compatibility with large sites and will take a long time to generate a sitemap (if it gets generated at all). My solution is this plugin, available on the WordPress plugin repository.

This plugin does not have any administration interface, and when activated “just works”. If you’re code-savvy, however, here are a few filters you can use to change the behavior of the plugin:

• scalable_sitemaps_news_category – Return the slug of the category which you want to appear on your news sitemap
• scalable_sitemaps_pages – Return false to disable displaying pages in the sitemap – alternatively, filter which categories are shown
• scalable_sitemaps_categories – Return false to disable displaying category pages in the sitemap – alternatively, filter which categories are shown
• scalable_sitemaps_users – Return false to disable displaying user pages in the sitemap – alternatively, filter which users are shown
