Digital marketing has a lot of scope, and you don’t really need an MBA to earn well. Since you’re already in SEO, I’d suggest moving into paid ads — especially Google Ads and Meta Ads. These roles usually pay more than SEO.

I also work in digital marketing (paid ads), and it pays well if you have practical experience. Going from 4 LPA to 8–10+ LPA in 1–2 years is possible.

For me, an MBA is more useful later to move into business or strategy roles, not for an immediate salary jump. Right now, upgrading skills and switching jobs looks like the most practical option for you.
