Why don't people talk about Link building much?

Hello! I have been developing a local online store through the social media. Now I'm having my online store and I'm planning to do SEO by myself while learning about it because I love to build my own business. I read articles about gsa ser but I was wondering weather is it still worth buying it. As I'm aware of, it comes at a monthly cost even the tool can be purchased with a one time payment.

What are the other trending ways to rank a website? Thoughts and suggestions are most welcome. Thanks!

Firstly if you are asking about GSA SER, it means you're not proficient in using it. One easy way to screw up your site is by spammy links created by seo tools where the operator doesn't know how to run these campaigns.

If you're wanting to rank and maintain rankings, you want to avoid these methods.
