Pros
If your website or brand has a good reputation, this may convince people to click on the link. If they see the website title or the brand.
The term at the right of every snippet title may bring additional values to understand the title. For example, when we read “Is Harvey Weinstein an offender or a victim? – DefenseOfMen” in the google search result. We understand that the webmaster wants to target men and that the content of the website is likely about defending men.
Cons
If people don’t know your brand or your website, they may misinterpret the website title. They may think that the word or terms at the end of the title are spam.
If your brand / name can be associated to something negative, people will not click on the title. For example, the company “Monsanto” has been criticized a lot by environmental activists. However, this company has decided to add the word Monsandto after every title of its website.

We found that if there are many words in the snippet title, this weakens the weight of every word for SEO. That’s why it is better to have a title as short as possible. So, for instance, it is a bad idea to add a long term after the title like ” – Indian recipe reviews”. That’s three words to add.
