Within HREFLang Builder our main project “view” screen and export will show you how many URL’s are included for each country as well as any errors.  This is a great way to monitor consistency between counties.

In this example, nearly every country had a different number of URL’s.  Many are due to errors which are represented in the red numbers.

Best Practice

1.  Review the counts of URL’s and understand why some markets have more than others.  Check your source to make sure it captured all the URL’s.
2.  Review the error logs to see which of the pages have errors.
