How to crush competition?

Recently launched a streetwear brand selling mainly stylish jeans made of very comfortable material.

Competitors using the same supplier are doing well with paid ads (FB/IG) but they have no idea how to use Google (SEO, Ads, etc.).

So my question to BHW is, what are some BH ways to push them out of the market?

I think your best bet is to dominate SEO as traffic channel since they are not using it.

People use search to confirm their ideas and motives. Like motive to buy something.

They might see your competitors on FB, visit their site but then go to search to do "research" and confirm... where you pop up
