Create Archive templates

Hello, We have and 5 years old SEO WP site and we put a lot of time and energy into this template. The developer makes very good marketing for this template that this is the best SEO template in the word. Just they forgot to say to you: “we did not make the archive template”. So you can not use categories and tags to create unique content for Google with this technique. I think this is not an SEO template… But we believe in this team and our trouble that we did not check this section of the theme. We think it includes this feature because it is naturally in an SEO theme that they think for tags and categories. We learned from this that you have to ask all your questions + questions which you think are naturally. We would like to see the same as the blog page: https://pallascommunication.hu/blog/ And our archive page if you click for a tag: https://pallascommunication.hu/tag/adwords-kampany/ So we would like to solve it and I hope this plugin can do that because we do not want to change the template. I hope someone has the same problem and they can solve it. Thanks for your help. Mary The page I need help with: [ log in to see the link]
