If I were you, I would focus on using Alexa boosting tools or services for their "safest use".
The safest use, of course, is to generate relationships with established websites in your niche.
You have to remember that if your website is just brand new, a lot of established players in your niche would not waste their time on you.
It doesn't matter how good your content is.
It doesn't matter how engaging your materials are or how much love you get from social media.
They just wouldn't bother with you if you don't have traffic.
As you probably already know, traffic is gold on the internet.
If you use Alexa Master of any other Alexa boosting tools, you can get these people to at least take a second look at your website.
I'll just leave it at that.
