Is it worth making a link from a metalworking site to another authoritative site with informational content (GOST, etc.)?

Question

Search Engine Optimization

The site has recently entered the top 1-3 of Yandex for many queries in the niche. Now I decided to study the issue of links. For active promotion in Google, where, as I understand it, you can’t get to the top without links. Please advise what is the right thing to do - is it worth making a link from one of the landing pages of the site to another authoritative source with official documentation (with GOST, TU, SNiP, etc.)? And how is it better to do this - a link in the text <a href="">, or through Yandex Webmaster (in the External links section)?
So far, there are no links on the site at all, except for some stray ones that themselves appeared in Webmaster.

Answer 1

is it worth making a link from one of the landing pages of the site to another authoritative source with official documentation (with GOST, TU, SNiP, etc.)?

yes, of course, it is worth putting a link. External links to authoritative sources also affect the ranking of the site in a positive way.

Answer 2

The link needs to be put, only the question is in the trust of the resource and how do you change it. Official websites of universities, state structures - approx. If some kind of site with articles, then it is not necessary.
