As a tech blogger I’m reaching out many bloggers in my niche for guest posting, but all are accepting sponsored posts by charging some amount. Is it good to pay for them to get links? And I have seen many freelancers who are providing guest posting services on upwork and peopleperhour, is it good to hire them??
Yes but don’t pay to those who are selling openly!
If you can hire premium sellers then only it will benefit you else you will get you bad results only.
