dataLayerって何ですか? Ver.2

データ レイヤー(data layer)

dataLayer入門

前回の下記の記事、

に続いて、dataLayerの解説です。

ショッピングカートなどでは、商品の価格などの情報が最初からHTMLソースに含まれているわけではありません。商品がカートに追加されると、価格などの情報が動的に生成され、HTMLソースに反映されることになります

具体的には、JavaScriptやPHPなどのプログラムを使用して、ユーザーが商品をカートに追加すると、その商品の価格などの情報を動的に生成し、HTMLソースに挿入することができます。このようにして、ユーザーがカートに追加した商品の情報が表示されます。

さらに、Google Analytics 4(GA4)を使用する場合は、価格などの情報をdataLayerに送信することができます。dataLayerは、JavaScriptで管理される配列であり、ECサイトで発生したイベントやアクションに関する情報を格納します。GA4とGoogle Tag Manager(GTM)は、dataLayerの情報を監視し、必要に応じてデータを収集してGA4に送信します。これにより、GA4でECサイトのトラッキングや分析が可能になります。

具体的には、以下のような流れで動作します。

  1. ECサイトで商品がカートに追加されると、JavaScriptやPHPなどのプログラムが動的に価格などの情報を生成し、HTMLソースに反映します。
  2. 同時に、dataLayerにカート追加のイベント情報や、商品の情報(価格など)を送信します。
  3. GTMがdataLayerの情報を監視し、GA4に送信するためのタグをトリガーします。
  4. GA4がdataLayerから収集した情報を使用して、ECサイトのトラッキングや分析を行います。

以上のように、ECサイトでの動的な価格情報の生成や、GA4でのトラッキングや分析には、JavaScriptやPHPなどのプログラミング言語や、dataLayer、GTMなどのツールが必要になります。

JavaScript、PHP、Python、Rubyなど

価格の動的な書き換えには、PHPを含め、いくつかのプログラミング言語が関わってくることがあります。

具体的には、以下のような言語が挙げられます。

  1. JavaScript:ECサイトにおいて最も一般的に使用される言語で、クライアントサイドで動的なコンテンツの生成や変更を実現するために使用されます。
  2. PHP:サーバーサイドのプログラミング言語で、ECサイトのバックエンド処理やデータベースの操作などに使用されます。価格情報などの動的なコンテンツの生成や変更にも使用されることがあります。
  3. Python:サーバーサイドのプログラミング言語で、ECサイトのバックエンド処理やデータ分析などに使用されます。価格情報のスクレイピングなどにも使用されることがあります。
  4. Ruby:サーバーサイドのプログラミング言語で、ECサイトのバックエンド処理やWebアプリケーションの開発に使用されます。価格情報などの動的なコンテンツの生成や変更にも使用されることがあります。

以上のように、ECサイトにおいて価格情報などの動的なコンテンツの生成や変更に使用される言語は複数あります。どの言語が使用されるかは、ECサイトの設計や開発者の選択によって異なります。
