Paid advertising gets a bad reputation because most campaigns are built to spend, not to sell. Done right, ads on Meta and Google are simply the fastest way to put your offer in front of people who are ready to buy.
Before spending a rupee, you need three things: a clear offer, a page built to convert, and a way to track results. Skip any of these and you are gambling, not advertising.
Start small and let data lead. Test a few audiences and creatives with a modest budget, kill what does not work, and pour more into what does. The businesses that win are the ones that treat the first month as learning, not judgement.
And always measure against the right number. Impressions and clicks feel good, but the only metric that matters is cost per customer against the value of that customer. Get that ratio right and paid ads stop being an expense and become an engine.
