How to automatically insert UTM tags when switching from a sickle?

Question

Search Engine Optimization

When it comes to the use of UTM in contextual and SMM advertising, everything is very clear - we put the necessary tags in the link -> profit. But if the transition comes directly from the search results, the same metric is dull and leaves requests empty in 50% of cases, although the source is indicated as a transition from the search results.
Is there a publicly available plugin that automatically tags URLs for links? A long walk around the expanses of the Runet did not bring results, although I remember exactly that I saw a similar implementation on some sites.
That is, if the transition comes from Yandex, we get a URL like

http://site.ru/page.html?utm_source=yandex&utm_medium=SEO&utm_term=поисковый_запрос

And preferably if from another site

http://site.ru/page.html?utm_source=website_name&utm_medium=Direct

Answer 1

What is the plugin for? To Yandex, Google? To someone else's site?
All utm-tags are put in one way or another by the owners of sites or advertising systems, for example, when setting up contextual or display advertising.
As for the loss of the source of the transition, this is possible if the transition occurs from httpS (for example, Google issuance) to http (for example, your site). Translate the site to https and you will be analytically happy.
