Google検索エンジンの結果ページのページタイトルは何ですか？

Googleは、検索エンジン結果ページ（SERP）のページタイトルとして表示されるものを制御します。かつては<title></title> element, Google now dynamically generates titles, even using text not explicitly found within the page's source code.

This practice, which has reportedly existed for about a decade, has recently undergone an update. Google's explanation indicates the new system aims to create more effective titles that accurately represent the page's content, regardless of the search query. They explicitly state that this system goes beyond HTML <title></title> tags, utilizing visible text, including headings (H1, H2, etc.), large and prominent text styled with CSS, and even text within links.

This change is likely a response to poorly written <title></title> tags—those that are overly long, filled with irrelevant keywords, or simply uninformative.

While Google's intention may be to improve SERP clarity, this raises concerns about site owner control. Google's algorithm could theoretically override a site's <title></title> tag with any text, potentially negatively impacting a website's image.

This situation bears resemblance to AMP (Accelerated Mobile Pages), where Google imposed strict rules for mobile website performance, incentivizing compliance with improved SERP rankings. However, unlike AMP's opt-in nature, Google's new title generation is imposed without explicit site owner consent. While it avoids development time investment, it also removes control over a crucial aspect of search engine optimization.
