I was doing some SEO tests recently and one of the things I was trying was a blogger blog and basically shooting all kinds of backlinks at it with GSA no tiers. I seen it ranking fast like usual in this scenario in the past, but after a couple days it has disappeared off Google been gone now for about 20 hours maybe. The blog is still indexed on Google just not ranking anywhere for the keywords. Is this disappearance temp or will it never come back ? It's odd cuz I have other bloggers still ranking months later from this same style.
