This option allows you to remove the index.html from any country home page or folder to match other countries that do not use them.
For example, if you have an older site in Bulgaria that still has the home page as mysite.bg.index.html that will also work as mysite.bg then we can remove “strip” the index.html from the URL so we can match it.
To enable this feature check the box and any URL that contains index.html will have that element removed. If all of sites use index.html then you should leave this feature turned off.
In the example above there are three markets that don’t appear to have home pages. This is due to these being older sites where the home page is represented using an index.html. Since the other countries do not use it the system shows it is missing. If we remove the index.html from these URL’s it will match. You could also solve this using a canonical tag on the pages and enable error checking in your CMS or in HREFLang Builder.
If you are not sure if you have this problem or not leave this feature disabled and review your Table of Mapped URL’s and if you are missing country home pages or other key category pages then review the URL’s and if your system is inserting index.html to the URL in a few markets you can enable the feature.
