Need suggest Backlink

Hello, Ummm I need backlink service that can give the proof for about 1 month. I have a taget keyword "slot gacor" but, it's really hard keyword. Then, I suggest to my boss targetting to longtail.
Anyone who have that qualification just send me pm or reply this thread. Because I really need you ^^

What do you mean by "proof for 1 month"? Do you mean the vendor should provide you with any guarantee or something else?

"Slot gacor" is a highly competitive keyword, fine, so you haven't ranked for it yet?

When "slot gacor" is your target keyword, why do you focus on long-tail keywords? Your targeted keyword can definitely rank if everything is done correctly.

Btw, post your exact requirements in the HAF section, and sellers will get in touch with you.

I mean like some guarantee, and that keyword is really hard to touch. That's why I suggest to my boss change the keyword into longtail.
I need PBN, Tier Backlink and guarantee to get page 1 using white hat or black hat way it's no problem just want to get on that keyword.
If anyone have all of that just pm me.
