Use entry variables in meta tags about craft-seomatic

[khalwat]

So the way you will want to do this will be using the SEOmatic APIs... something like this:

{% set rentalPrice = entry.rentalPrice %}
{% do seomatic.meta.seoDescription(entry.metaDescription|replace({'[rentalPrice]': rentalPrice})) %}

See here for details: https://nystudio107.com/docs/seomatic/using/#seomatic-variables

Also you generally don't need a separate metaDescription field in Craft, typically you can set up content mapping in SEOmatic -> Content SEO as discussed here: https://nystudio107.com/docs/seomatic/overview.html#the-meta-cascade

Or if you really do need a per-entry custom SEO overrides, you can use an SEO Settings field so things will work more automatically for you: https://nystudio107.com/docs/seomatic/fields.html

Thank you, Andrew. It works and was exactly what I was looking for. I read earlier the pages of the last 2 links. I decided to create and use separate meta fields for 2 reasons assuming that SEOmatic stores its data separate from or different to Craft CMS:

1. If the plugin is discontinued or I decide to uninstall it, I would like to have saved the meta information with my entries.
2. It is probably easier to handle exports of entries which include meta data.

Honestly, I don't know how SEOmatic technically works and where it stores the data. I just didn't want to loose it or re-enter it when the plugin changes (bug, discontinuation, price increase, etc.).

Okay, sounds good. Generally you don't need a separate meta description, as pulling from existing content via Content SEO usually works better than manually written descriptions/titles, because they reflect the content on-page.
