For an Indian startup, a minimum viable Google Ads budget is ₹10,000–₹15,000 per month to collect enough click data for the algorithm to optimise meaningfully. Competitive verticals like real estate, insurance, legal, and B2B SaaS require ₹30,000–₹1,00,000/month to compete effectively. Divide budget between a structured test phase and a scaling phase once winning keywords are identified. While building paid traction, invest simultaneously in content marketing and SEO so that organic traffic reduces your dependency on paid spend over the medium term.
