Chuyển hướng website khi truy cập bằng điện thoại

1534 Lượt xem

Với sự phát triển chóng mặt của Smart Phone, tất nhiên là các website sẽ tập trung phát triển mảng dành cho di động và nó cũng nằm trong tiêu chuẩn đánh giá thứ hạng seo.

Thông thường developer sẽ phát triển website dành cho di động theo hai hướng: thiết kết responsive web hoặc xây dựng giao diện mới trên di động và chuyển hướng khi người dùng truy cập vào trang giao diện dành cho PC.

Vậy, làm sao biết người dùng sử dụng thiết bị Smart Phone mà chuyển hướng?

Việc chuyển hướng website này khá dễ thực hiện với một vài cách sau

1. Dùng .htaccess
