What should be the title for pagination?

Question

Search Engine Optimization

Can you please tell me whether it is necessary to add a number to the title of the page when paging?
For example, on the forum for the topic on the first page, the title is: "My topic", and on the second page "My topic - page 2".
I am interested in whether this is necessary from the point of view of search engines - if I make the same title on all pages of the topic, they will not swear?
If it's not difficult, then I ask you to answer with justification in the form of a link or personal experience.

Answer 1

Big profit - it will not. Search engines hardly look at the title, they are more interested in h1.

Answer 2

Google webmaster with shitty titles told me about this, that a lot of the same. And SEO plugins for the press first put a unique title, and then the name of the site, for example.
