When SEO takes ages and PPC dies the moment you stop spending which one actually makes sense for business?

[TiaGoyette]

Running a small D2C brand online (handmade home décor). Tried boosting on Instagram and a little bit of Google Ads. PPC gives instant traffic but once I stop the ads, traffic also zero.
SEO I keep hearing is long-term but honestly, I don’t have patience to wait 6–8 months. In India, competition is already crazy in every niche.
So tell me honestly for a small business here, which is smarter: keep burning money on PPC, or just grind it out with SEO?
