What kind of backlinks do e-commerce sites (shopify) need to configure?

Hi, I am new to SEO optimization. I heard that there are many powerful people in the Blackhat world. I want to learn something here.



I have a shopify store that has been open for a month. It is used to sell clothes.



I see some professional words here, such as first-tier backlinks, second-tier backlinks, web2.0. Here I have some questions.



1. How to improve the keyword ranking of shopify's product pages if you set the backlinks for paid purchases as second-level backlinks?



2. Setting up a second layer of backlinks is equivalent to setting up a funnel, so isn’t the percentage of buyer loss increased?



3. What type of second-tier backlink is suitable for a website that sells clothes?



Any of your comments will help me a lot, thank you.

I think I have understood those issues. For example, T1 Links, T2Links.

My new question is which T1 Links are suitable for e-commerce shopping?

the usual links (PBNs, guest posts, etc) work just fine. There are probably other ranking factors that matter for ecom sites besides backlinks, but the usual backlinks are just as good
