Multilanding on Wordpress. What are plugins for creating content substitution?

Question

Content

Please tell me analogs of the plugin or good services like Yagla, but there is no desire to buy Yagla:

The task is this:
Replace the title, text, picture with the values ​​\u200b\u200bthat are specified in the URL.
For example:
1)
a link like site.ru/?utm_source=zag1
Then the text on the site will be: Heading 1
2)
a link like site.ru/?utm_source=zag2
Then the text on the site will be: Heading 2
There is a plugin - Targeted Content Creator https: //codecanyon.net/item/targeted-content-creat...
It has not been updated for a long time and costs 800 rubles.
I also found a php script through which you can implement content substitution smartlanding.biz/skript-multilendinga.html
It is clear how to implement, but you need to do it manually. So who knows a good solution to this issue?

Answer 1

It is clear how to implement, but you need to do it manually.

What do you mean by "manually do"? You have a ready-made code hanging there, which is simply embedded in the template.
If you mean that you need the ability to prescribe UTM value => text pairs in the admin panel, then read about creating template settings.
