Display categories or tag on meta data Hugo inside head tag

Yesterday I struggle with displaying a list of categories or tags inside a head tag of my Hugo project. I want to use this on my meta tag to make it more dynamic a.k.a better for SEO.

Luckily I found a simple way to do it. The trick is using delimit to combine it as a string and wrap it inside “with” clause

{{ with .Params.tags }}{{ delimit . ", "}}{{ end }}

Want to save it on a string and reuse it later? yes, you can

{{ with .Params.tags }}{{ $listtags = delimit . ", "}}{{ end }}

Now you can use $listtags by combine it with another string. Learn how to concatenate a string in Hugo
