Hello friends,
Please let me know the answer for that , what is Canonical issue?
Canonical issue means when you forget to type www in the search engine. Search engine will consider the site with www and without www as different sites. This problem can be easily avoided by redirecting our site to the www version even if someone types the non www version. [URL=“http://batdongsan.com.vn/Dang-tin-rao-vat-ban-nha-dat.html”]
