Check if all links that you will receive are quality DA/PA and are actually indexed.
Make sure to not spam the backlinks in one sitting. They need to look more or less spread.
not 80 links in 1 day.
7 the day after tomorrow.
Make sure you are not getting nofollow links... sounds stupid but I got a nofollow package once.
But.... nowadays I don't think nofollow and dofollow have different impacts...
Google is 100 times smarter than it used to be 7 years ago. When I first started SEO.
Get social signals with the backlinks (in the same time) it will look very natural to Google.
Get some traffic in the same time.
This will look very natural and google will move your links up the ladder very fast.
If you can't do those things just stick with the backlinks, you will get results as long as the links are relevant and have a good standing da/pa.
