Effective Facebook advertising in India requires a minimum of ₹5,000–₹8,000 per month for a single campaign objective with a small, defined audience. Below this, the algorithm cannot exit the learning phase and produces erratic results. For lead generation campaigns targeting a specific Indian city or B2B audience segment, ₹15,000–₹25,000/month enables proper creative testing. Facebook ads reach audiences who are not yet actively searching for your product - pairing paid social with SEO and content marketing ensures you capture both discovery-stage (social) and intent-stage (search) audiences simultaneously.
