How to link two sites with links to each other?

Question

Search Engine Optimization

Hello,
I really need advice from knowledgeable people!
I have two sites. One worker. Another - started specifically for the blog. For some reason, I can't blog on the first site. The first site is for sale, sells services. Blog - only articles and nothing more. But the theme of both sites is the same. The sales site is pretty well pumped in SEO. Main pages top 1-3 Yandex.
So, in fact, the question is how to correctly make links from a selling site to blog pages.
It is planned that on one page of the sales site there will be one link to the main page of the blog, and, for example, 7 links to blog posts. That is 1 link = 1 page. In total, from one page of a selling site there can be around 8 links to various blog pages.
Perhaps there will be backlinks from the blog to the selling site.
Please tell me,
will this negatively affect the SEO of both sites?
Or would it be helpful?
I need to do this anyway. The question is what is right.
Thanks in advance for your replies and your time!

Answer 1

As a SEO specialist, it's better to keep a blog on the same domain ... (Move it)
If you follow your "plan", then you will give "weight" (belly) from the selling site to the blog.
Moreover, such a scheme may look suspicious from the PS side.
In any case, if you do so - all links in noindex. And to equate them as much as possible with natural links, the purpose of which is not to manipulate the issue (so that they don’t look like corrupt links) ...

Answer 2

From the selling site, put links in nofollow. It works in both search engines and "says" that the donor is not responsible for the content on the acceptor and forbids it from receiving "weight", even though it will be given from the donor.
But I would try to start on a few pages before rolling it out to the whole site. Well, be sure to monitor positions and traffic, although the probability of drawdown is minimal.

Answer 3

Any specialist will tell you that you need to cut content on the same seller. As an option, do it on a subdomain - Yandex will regard it as one site. For that, there is no need to transfer the weight with links and traffic from the content will also go.
Think 10 times and give up the idea of ​​a second site)
