Understanding HREFLang Builder Error Codes
If your project has activated error checking, you may see a report of errors in both the project update confirmation email and in the view screen.
Errors in Project Update Confirmation eMail
Once your project updates, you are sent an email that may list the overall status of the URLs in the project. The system lists the count of any errors.
Errors in Project Overview Screen
If you click on your View Screen, you will see the master list of countries and the number of URLs detected, and those with errors if you have no errors in your project, that is perfect!
If you mouse over the numbers in RED, a popup will display the types and numbers of each error type.

Why should I care about these errors?
- None of these pages with errors will be added to your final HREFLang XML file.
- Search Engines don’t have unlimited resources and won’t waste their time importing XML site maps that have a lot of errors we have built several error detections into the tool. You can turn this error checking off, but if you do you are responsible for any problem that comes from submitting a lot of junk to the search engines.
