The Alias will be used in the SEF URL. Leave this blank and Joomla! will fill in a default value from the title. This value will depend on the SEO settings (Global Configuration->Site).
Using Unicode will produce UTF-8 aliases. You may also enter manually any UTF-8 character. Spaces and some forbidden characters will be changed to hyphens.
When using default transliteration it will produce an alias in lower case and with dashes instead of spaces. You may enter the Alias manually. Use lowercase letters and hyphens (-). No spaces or underscores are allowed. Default value will be a date and time if the title is typed in non-latin letters .
Ordering:
New articles default to the first position in the Category. The ordering can be changed in Backend.
