Which is the best possible way to do Guest Blogging?

[PaulDragos]

I have built hundreds of links, classical guest posts you have to pay money...

The only client where I managed to get some links for free was a charity but even then, they are still much stricter on the article you post on their site.

If you have sites that sell something/affiliate. 99.5% of the time, you need to pay.

Hello, the best way is money for guest posts, you get links easily but the best is for free because why pay as much as you can for free but it will take a lot more time unfortunately than offering money for it but I think you will get quite a good amount after some time

Let's recap the main steps:

Write three or four round-up posts.
Cultivate relationships with experts in your niche.
Research the type of blog posts they publish (Topic, Headlines, Intros, Word Count)
Reach out to them with three winning guest post ideas.
Deliver your guest post and be a pleasure to work with.
