      <description>&lt;blockquote&gt;
&lt;p&gt;TL;DR: Khi cross-post lên DEV, hãy dùng &lt;strong&gt;canonical URL&lt;/strong&gt;, đăng &lt;strong&gt;bản tóm tắt&lt;/strong&gt; thay vì full text, và tối ưu &lt;strong&gt;ảnh/alt&lt;/strong&gt;. Đây là checklist 1 trang để làm đúng ngay.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;h2&gt;
  
  
  1) Đặt canonical URL
&lt;/h2&gt;

&lt;p&gt;&lt;strong&gt;Vì sao?&lt;/strong&gt; Báo cho Google đâu là bản gốc, tránh trùng lặp và bảo toàn tín hiệu SEO cho bài trên site của bạn.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Cách làm (2 lựa chọn):&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;Trong front matter&lt;/strong&gt;: thêm dòng &lt;code&gt;canonical_url:&lt;/code&gt;
&lt;/li&gt;
&lt;/ul&gt;



&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;
yaml
canonical_url: "https://your-domain.com/blog/cross-posting-canonical-image-seo/"
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;
