We have integrated the ability to auto-generate new HREFLang XML files on a weekly or monthly basis from an upload, FTP or autogenerated list from your CMS.
Many of our users point HREFLang Builder to their dynamically updated XML files, XML export from Adobe AEM or an FTP and we import them, update the HREFlang XML. Once completed we can FTP them back to a secure drive or email them to your designated contact. We have also added email updates giving you error status, new or removed source files, and country/languages to monitor the quality.
