How to use the link mass of the old working site on new sites?

Question

Search Engine Optimization

I have a site that generates some content for other sites. Instead, after generation, the visitor is shown a request to place a link to my service under the generated content. At the moment, these are more than 7000 good links from thematic articles to my service.
I regularly launch new infosites, and of course I am also interested in link building. The question is, can I somehow use my service with its backlinks to promote new sites? Does anyone have experience and ideas?
How else can you use this link mass? And then at this moment it is a vicious circle - the generation of backlinks for the sake of generating a new portion of backlinks.

Answer 1

Well, you offer to make backlinks to new sites for them

Answer 2

Why are you setting a minimum width for the container of your blocks?
Set it to the content block:

But for the phone, you need to use custom styles and the viewport meta tag

It is necessary to limit the size of the parent block (the one that drives up under the fixed block).
