Hi @Karishma_begumSh,
Stemap - make sure your pages output metadata that Coveo can read - easiest via sitemap.
In sitemap XML, include custom metadata:
<url>
<loc>https://www.example.com/mypage.html</loc>
<coveo:metadata>
<title><![CDATA[Page Title]]></title>
<description><![CDATA[Meta description here]]></description>
<tags><![CDATA[tag1;tag2;tag3]]></tags>
</coveo:metadata>
</url>
Extend AEM’s sitemap generator to include these.
Once you done, create fields in Coveo
and last step is add mapping - link metadata to these fields.
