私の個人サイト「ツムンテマの苔庭」は、この度jimdofreeドメインからtsumuntema.comという独自ドメインへ移行し、新たなスタートを切りました。その際にやった301リダイレクトの方法を書きます。
やり方
私が改めて書くよりも、私が参考にしたブログ記事を見たほうが早いです。
旧サイトのジンドゥーJimdoから新サイトURLへのリダイレクト方法
今回の独自ドメインによる新サイトへのお引越しで旧サイトとなったジンドゥー（jimdofree.com）フリー版からのリダイレクトするための設定方法がそれなりに調査したり検証を行ったので忘れないようにメモしておきます。
www.enoanoarts.com
もっと詳しく
しかし、これで記事が終了してはつまらないので、私が実際に書いたヘッダーコードを載せておきます。
先ほどのサイトにちらっと書いていたように、javascriptで条件分岐を書き、ページごとにリダイレクト先を指定しています。
location.href の値が “https://tsumuntema.jimdofree.com/my-characters/kokeiro-kage/” だとすると、
location.hostname: “tsumuntema.jimdofree.com”
location.pathname: “/my-characters/kokeiro-kage/”
<link rel="canonical" href="https://tsumuntema.com/" />
<script type="text/javascript">
