Script báo link không hoạt động trong Google Adwrods

17/05/2018

1265

Trong quá trình hoạt động của website, vì lý do nào đó khiến một vài link bài viết, hoặc link sản phẩm/dịch vụ không còn hoạt động. Nếu tài khoản Adwords của bạn chạy nhiều chiến dịch thì việc kiểm tra từng chiến dịch mỗi ngày là rất tốn thời gian và đôi khi bị bỏ sót.

Vì vậy, việc cài đặt script này là việc không thể thiếu cho người quản lý tài khoản.

Dưới đây là hướng dẫn cài đặt script báo link không hoạt động trong Google Adwords

Bước 1: Tạo một file Google Sheet để hệ thống ghi dữ liệu những link không hoạt động

Truy cập VÀO ĐÂY để tạo bản sao file và lưu vào thư mục drive của bạn.

Chia sẻ file có thể sửa cho những người có link các bạn có thể xem hình bên dưới để script Google Adwords có thể ghi giá trị.

Bước 2: Cài đặt Script kiểm tra link không hoạt động quảng cáo trong tài khoản Adwords

Một trình soạn thảo sẽ xuất hiện, các bạn dán đoạn code dưới đây vào.

Lưu ý:

SPREADSHEET_URL: ‘YOUR_SPREADSHEET_URL’, thay link Google Sheet bạn tạo bước 1 vào.
RECIPIENT_EMAILS: [ ‘YOUR_EMAIL_HERE’ ], thay địa chỉ email của bạn để nhận thông báo link hỏng.
LABEL: ‘LinkChecker_Done’, tạo label để script gắn lable link đã check

/**
 * @name Link Checker
 *
 * @overview The Link Checker script iterates through the ads, keywords, and
 *     sitelinks in your account and makes sure their URLs do not produce "Page
 *     not found" or other types of error responses. See
 *     https://developers.google.com/adwords/scripts/docs/solutions/link-checker
 *     for more details.
 *
 * @author AdWords Scripts Team [adwords-scripts@googlegroups.com]
 *
 * @version 2.1
 *
 * @changelog
 * - version 2.1
 *   - Added expansion of conditional ValueTrack parameters (e.g. ifmobile).
 *   - Added expanded text ad and other ad format support.
 * - version 2.0.3
 *   - Added validation for external spreadsheet setup.
 * - version 2.0.2
 *   - Allow the custom tracking label to include spaces.
 * - version 2.0.1
 *   - Catch and output all UrlFetchApp exceptions.
 * - version 2.0
 *   - Completely revised the script to work on larger accounts.
 *   - Check URLs in campaign and ad group sitelinks.
 * - version 1.2
 *   - Released initial version.

* @name Link Checker

* @overview The Link Checker script iterates through the ads, keywords, and

* sitelinks in your account and makes sure their URLs do not produce "Page

* not found" or other types of error responses. See

* https://developers.google.com/adwords/scripts/docs/solutions/link-checker

* for more details.

* @author AdWords Scripts Team [adwords-scripts@googlegroups.com]

* @version 2.1

* @changelog

* - version 2.1

* - Added expansion of conditional ValueTrack parameters (e.g. ifmobile).

* - Added expanded text ad and other ad format support.

* - version 2.0.3

* - Added validation for external spreadsheet setup.

* - version 2.0.2

* - Allow the custom tracking label to include spaces.

* - version 2.0.1

* - Catch and output all UrlFetchApp exceptions.

* - version 2.0

* - Completely revised the script to work on larger accounts.

* - Check URLs in campaign and ad group sitelinks.

* - version 1.2

* - Released initial version.
