SNS とリッチリザルト
og:url が canonical と一致しています
重要な理由
Social networks use og:url to group shares and likes. If it differs from the canonical URL, shares may be split between two addresses or credited to the wrong page.
修正方法
- Set og:url to exactly the same URL as the canonical tag.
- Most SEO plugins can do this automatically.
