How Google Ads pricing works
You don't pay a subscription for Google Ads — you set a budget and pay per click (or per action) as an auction decides your cost. Your cost per click depends on how many advertisers are bidding on your keywords, your quality score (relevance of ad and landing page), and the intent of the keyword. Cheap, low-competition keywords can cost under a dollar; competitive commercial keywords in fields like legal or insurance can run tens of dollars per click.
What a workable budget looks like
The mistake is setting a budget too small to gather data. If a click costs $5 and you need roughly 20–30 clicks to learn whether a keyword converts, a $150/month budget can't test even one keyword properly. A budget needs enough volume to reach statistical signal — for many small businesses that's a few hundred to a few thousand dollars a month, depending on the click price in their market.
Ad spend isn't the only cost
Beyond the spend that goes to Google, factor in management — whether that's your time or an agency fee — and the landing pages and creative the ads point to. Great targeting sending traffic to a weak page wastes the whole budget. Webly Studio runs Google Ads to cost per acquisition and payback, not just clicks — see our paid ads service, or our guide on paid ads cost per lead.
