I have multiples url's directing to a single page, ex:
www.example.com.br/phone-calls-right-now
www.example.com.br/phone-calls-for-yesterday
www.example.com.br/phone-calls-cheaper
www.example.com.br/phone-calls-for-free
and redirecting 301 to this single page:
www.example.com.br/phone-calls
This is acceptable? the search engine see like a duplicated content?
If it's an empty page, there is an way to put an <meta name="robots" content="noindex, follow">
and let it there?
