How Google Ads Works

Google Ads is a pay-per-click platform. You bid on keywords; when someone searches that term, your ad enters an auction. Google ranks ads by bid × Quality Score. You only pay when someone clicks.

Average CPC in India ranges from ₹5 to ₹200 depending on industry. Most small businesses start with ₹15,000–₹30,000/month in ad spend.

Basic results (impressions, clicks) within 24–48 hours. Meaningful lead volume typically requires 2–4 weeks of optimisation for the algorithm to learn.

For ecommerce, 3X–5X ROAS is solid. For lead generation, cost-per-lead is a better metric. A Google Ads expert benchmarks against your industry average CPC.

Quality Score is Google's 1–10 rating of your keyword relevance, expected click-through rate, and landing page experience. A higher Quality Score means you pay less per click and achieve higher ad positions than competitors who bid more. For Indian businesses, improving Quality Score is the single most cost-effective way to reduce CPC.

Manual CPC lets you set individual bids for each keyword — giving you precise control. Smart bidding (Target CPA, Target ROAS, Maximise Conversions) uses machine learning to adjust bids automatically. Smart bidding outperforms manual only when you have 30+ conversions per month feeding the algorithm. Below that threshold, manual or enhanced CPC is usually better.

Most small businesses in India start with ₹15,000–₹30,000/month. Competitive industries like real estate or legal may need ₹50,000–₹2L/month for meaningful volume. The minimum viable budget depends on the CPC in your industry — a keyword at ₹50 CPC with a 5% conversion rate needs ~20 clicks (₹1,000) to generate one lead.

Performance Max (PMax) is Google's fully automated campaign type that runs across all Google channels — Search, Display, YouTube, Gmail, and Maps. It works best for ecommerce with a product feed and for businesses with significant conversion history (100+ conversions/month). For new accounts or low-budget campaigns, starting with standard Search campaigns gives more control and learning speed.

Working Google Ads show: accurate conversion tracking in your account, a cost-per-lead or cost-per-sale within your target economics, a positive return on ad spend (ROAS) or return on investment (ROI), and improving metrics week over week. If your account shows clicks but zero conversions, conversion tracking is likely broken — the most common issue in Indian accounts.

Managing Google Ads yourself is viable for budgets under ₹10,000/month with simple campaigns. Above that, the cost of mistakes (wrong match types, missing negative keywords, broken tracking) typically exceeds the cost of hiring an expert. A certified Google Ads consultant in India typically charges ₹10,000–₹20,000/month flat fee — far less than what most businesses waste in unoptimised spend.
