Hi, I'm trying to SEO for the site http://ungvien.com.vn We also owned the ungvien.com domain and forward to .vn domain. 4-5 days ago, I sometimes found that both domain appear next in Google. All our effort are for the main domain ungvien.com.vn, I don't know why it appear both? Is it good or my site may be banned by Google ? Any wrong with my SEO ? Below are the google result for keyword "tim viec", 2 domain rank at 11th an 12th http://www.google.com.vn/search?hl=...n-US:official&hs=E9p&q=tim+viec&start=10&sa=N anyone could give me an advice?
This is a canonical issue. But if you've already 301'd the .com to the .vn they're nothing else you need to do. Just wait until Google recrawls the .com version and it should fix itself.
4 or 5 days may be too soon to worry. Search engine spiders are very busy. They just need time to recrawl the .com to realize it forwards to another address. Just be patient.
