По мере развития веб-сайта добавляются новые страницы, а старые удаляются, что может привести к неработающим ссылкам. Синхронизация кампании Google Ads с веб-сайтом может быть сложной задачей для многих рекламодателей. Живая реклама может указывать на несуществующие страницы, что приводит к ухудшению взаимодействия с пользователем и неточной статистике Google Рекламы.
Средство проверки ссылок решает эту проблему, перебирая все ваши объявления, ключевые слова и дополнительные ссылки, проверяя, не содержат ли их URL-адреса «Страница не найдена» или другие типы ответов об ошибках, отправляя вам электронное письмо при обнаружении ответов об ошибках и сохраняя результаты проверки. его анализ в электронную таблицу.
Некоторые учетные записи могут иметь большое количество URL-адресов, которые невозможно проверить за один раз из-за ограничений по времени выполнения или квот . Сценарий предназначен для обработки этого случая, отслеживая его ход при нескольких запусках и проверяя только URL-адреса, которые он не проверял ранее. Сценарий использует термин «анализ» для обозначения одного полного прохода по всем вашим URL-адресам, даже если для его завершения требуется несколько проходов.
Конфигурация
Основные параметры скрипта можно настроить в электронной таблице.
- Объем
- Определяет, проверяет ли скрипт объявления, ключевые слова и дополнительные ссылки; и проверяет ли их скрипт, даже если они приостановлены. Большинству пользователей следует включить все три, чтобы убедиться, что все их URL-адреса проверены, но обычно нет необходимости проверять приостановленные объекты.
- Действительные коды ответов
- Список кодов ответов HTTP, которые считаются допустимыми. Большинству пользователей следует считать только
200допустимым кодом ответа . - Электронная почта после каждого выполнения скрипта
- Если вы включите эту опцию, сценарий будет отправлять вам по электронной почте сводку URL-адресов, которые он проверял после каждого запуска. Это может предоставить вам раннее предупреждение об ошибках URL-адресов вместо того, чтобы ждать, пока все ваши URL-адреса будут проверены (что может занять несколько запусков).
- Электронная почта после завершения всего анализа
- Если вы включите эту опцию, сценарий отправит вам сводную сводку по электронной почте после завершения проверки всех URL-адресов.
- Электронная почта, даже если ошибок не обнаружено
- Если вы включите эту опцию, скрипт отправит вам электронное письмо (на основе двух предыдущих опций), даже если он не обнаружил ошибок. Большинство пользователей предпочитают получать электронные письма только при наличии ошибок, но получение электронного письма даже при отсутствии ошибок может быть полезным способом убедиться, что сценарий работает по расписанию.
- Сохранить URL-адреса OK в электронную таблицу
- Если вы включите эту опцию, скрипт сохранит каждый проверенный URL-адрес в электронной таблице, а не только те, которые содержат ошибки. Большинство пользователей предпочитают сохранять только неработающие URL-адреса, но некоторые могут захотеть увидеть все URL-адреса, проверенные сценарием.
- Дней между анализами
- Используйте этот параметр, чтобы контролировать, как часто сценарий запускает новый анализ всего списка URL-адресов. Обратите внимание, что этот параметр определяет минимальное количество дней между анализами. Фактическое число может быть выше, если анализ занимает больше времени (например, если у вас большое количество URL-адресов). Подробнее см. в разделе Планирование .
Расширенная проверка ссылок
В некоторых случаях может быть недостаточно просто знать, что URL-адрес возвращает действительную страницу. Например, рассмотрим случай, когда страница продукта содержит текст «продукт снят с производства». В этом случае вы можете пометить страницу как неработающую ссылку.
Скрипт предлагает два варианта проверки:
- Строки отказа
Задайте для параметра Использовать простое сопоставление строк ошибок значение
Yes, чтобы искать вхождения в списке строк, определенных в строках ошибок . Любое вхождение, найденное на веб-странице, помечает страницу как неработающую.- Пользовательская проверка
Для еще большей гибкости для каждого URL-адреса и ответа можно использовать собственную функцию проверки JavaScript. Например, вы можете подтвердить, что заголовок веб-страницы содержит название вашего бренда, следующим образом:
- Установите для параметра Использовать пользовательскую функцию проверки значение
Yes. Вставьте свою пользовательскую логику проверки в функцию в верхней части скрипта:
function isValidResponse(url, response, options, entityDetails) { // Your custom logic here, returning true for valid links, false otherwise. // ... }
Базовая реализация уже существует, с примерами того, как получить доступ к тексту ответа.
- Установите для параметра Использовать пользовательскую функцию проверки значение
Планирование
Каждый раз, когда скрипт запускается, он автоматически определяет, следует ли ему возобновить уже выполняемый анализ или завершился ли последний анализ и пришло время начать новый анализ (в зависимости от параметра Дни между анализами ). В результате, независимо от того, как часто вы хотите запускать новый анализ, запланируйте запуск сценария ежечасно , чтобы каждый анализ выполнялся по вашим URL-адресам как можно быстрее.
Например, задайте для Дней между анализами значение 1 , чтобы сценарий запускал новый анализ не чаще одного раза в день. Если сценарий запланирован на ежечасный запуск и он завершает проверку всех ваших URL-адресов менее чем за день, последующие запуски будут немедленно прекращены до следующего дня, когда придет время начать новый анализ.
Как это работает
Чтобы отслеживать свой прогресс, скрипт создает ярлык и применяет его к вашим объявлениям, ключевым словам и дополнительным ссылкам после их проверки. Затем сценарий может идентифицировать проверенные URL-адреса при следующем запуске. После завершения анализа (проверены все URL-адреса) скрипт очищает метку для нового анализа.
Скрипт использует UrlFetchApp для проверки конечных URL и мобильных конечных URL.
