What are the sanctions of search engines for copying content from different sites?

Question

Search Engine Optimization

I'm building a site with a list of companies similar to "compare" only in a different segment. And I decided to display the news of these companies on the site, wrote the parser.
Situation:
- there is not a lot of content on the site yet
- the budget for the text is not yet provided for such a volume - the
news will be indicated with a link to the original - the
content will be taken from different sources
I read that search engines can block the site for this and also read that the reverse link+different sites can eliminate this problem. Can anyone clarify or give advice?
I observed a lot that articles are copied from habr or even from a toaster, and sometimes they go on the first page

Answer 1

I am creating a website with a list of companies

If this is the purpose of the resource, then focus on it, and not on how to "lure" traffic to the site, and then come what may.
Targeted traffic is the highest quality and most valuable. News, and even stolen news, is a dubious unrealistic way to achieve your goal within the framework of the original purpose of your resource.
And according to the subject: pages with a list of news / articles (i.e. sections) will be in the index, because. A "hodgepodge" of posts from different sites will have its own level of uniqueness within your resource.
Pages with news content: if you do not use micro-markup (which is not very good, but given the circumstances ...) - the search robot, due to its stupidity, will take allcontent from the page (menus, blocks with announcements like "read also", "similar news", "most read", etc.) and all this rubbish will be part of the content, which will "dilute" it into impudent swindled news and slightly increase % uniqueness of the page (depending on the ratio of the text in the news in relation to this rubbish, etc.).
But I don't understand why this pain? You just need to focus on what the resource is focused on and improve the quality and user experience. And the idea with the news is a utopian UG, as for me.

If you have 100% copy-paste, and even with external links, the site will not enter the search, not to mention the top positions.
If you have really large volumes and there is no time to rewrite them, then you can rewrite the text to start it and get a relatively unique text at the output that you can insert without reference to a copywriter.
