Placeholder Manager lets you replace dynamic placeholders in WordPress content including posts, pages, titles, Gutenberg blocks, and widgets.
It is useful for multi-site branding, affiliate websites, and managing reusable content variables like brand names, URLs, and emails.
Key Features:
<ul>
<li>Replace placeholders in content, titles, widgets, and blocks</li>
<li>Create unlimited custom placeholders</li>
<li>Easily update branding across your entire site</li>
<li>Save time by avoiding manual edits</li>
</ul>
<h3>Example Usage 1</h3>
Placeholders defined:
 Placeholder 
 Value
 {BRAND_NAME} 
 TrexHost
 {WEBSITE_URL} 
 https://trexhost.com
 {CONTACT_EMAIL} 
 support@trexhost.com
Content in a post/page:
Welcome to {BRAND_NAME}!
Visit our website: <a href="{WEBSITE_URL}" rel="nofollow ugc">{WEBSITE_URL}</a>
For support, contact us at {CONTACT_EMAIL}.
Output on the site:
Welcome to TrexHost!
Visit our website: https://trexhost.com
For support, contact us at support@trexhost.com.
<h3>Example Usage 2</h3>
If you have multiple WordPress sites, you can duplicate content while keeping each site’s unique branding. Export and import posts/pages normally, then adjust placeholders per site.
When importing, ensure URL rewriting is configured correctly in your import tool.
Note:
When using placeholders in hyperlinks like {WEBSITE_URL}, WordPress may automatically add “http://”, causing broken links. To fix this, switch to the HTML editor and use:
<a href="{WEBSITE_URL}" rel="nofollow ugc"></a>
