How can I add & in sitemap ?

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

The <lastmod> tag is automatically added to the XML sitemaps generated by Rank Math. Here’s our sample format where the last modified date is shown for that tag

However, the priority tag <priority> isn’t taken into consideration by Google and most of the popular search engines anymore and that’s why we don’t add them in our sitemaps. Google is smart enough to figure out these details on its own based on the crawl data of your site. https://www.seroundtable.com/google-priority-change-frequency-xml-sitemap-20273.html

Hope that helps.

Thank you.
