Are Google Ads Worth It For Small Business?

When someone asks are Google Ads worth it for small business, they usually expect a yes or a no. What they actually need is the handful of numbers that decide it, and a straight read on whether their market behaves the way Google Ads needs it to.

Take your average job value and multiply it by how many times a typical customer buys from you in a year. A plumber on 180 pounds a callout with two visits a year is looking at 360 pounds. A kitchen fitter might be 9,000 pounds once.

That number is your ceiling. Everything else here is about whether you can win a customer for meaningfully less than it. Nearly every bad ads decision we see traces back to somebody guessing this figure rather than checking it.

Work it out on the back of an envelope now:

• Average value of one job or order
• How many times a customer buys in a year
• What you can afford to pay to win one, and still make money

Google charges per click, not per customer, and clicks in competitive trades are not cheap. Legal, insurance, cosmetic and trades work regularly run 5 to 20 pounds a click in the UK, and some go higher.

The rough rule: expect twenty to fifty clicks to produce one enquiry, then two to four enquiries to win one customer. At 8 pounds a click that is roughly 240 pounds to an enquiry and 720 pounds to a customer.

So if a customer is worth 360 pounds, you are losing money on every one. That is not a reason to give up, it is a reason to fix the conversion rate or the order value before you spend, rather than after:

• Your average cost per click, from Keyword Planner or your own data
• Clicks per enquiry, roughly twenty to fifty until you have real data
• Enquiries per won job, which most owners can estimate accurately
• Multiply the three together for your true cost per customer
• Compare that against the ceiling from step one
• If it is close, the levers are conversion rate and average order value
• If it is nowhere near, fix those first and come back to ads

Google Ads only works where demand already exists. Somebody has to be typing the thing you sell into a search box, at the moment they want it.

Emergency and urgent services do brilliantly here. Boiler repair, locksmith, emergency dentist, man with a van. Nobody browses for those, they search, click the top result and call.

Where it gets much harder:

• New products nobody knows to look for yet
• Anything bought on impulse or discovery rather than intent
• Services with a six month consideration window
• Very local businesses in an area with almost no search volume
• Categories where the searches are all research, not buying

This is the one that quietly kills more small business ad accounts than bad targeting ever does. You have paid 8 pounds for a click and 240 pounds for an enquiry, and then it sits in an inbox until Thursday.

Speed to lead is not a buzzword, it is the difference between a 40 percent conversion rate and a 10 percent one. Ads amplify whatever process you already have, so if the process leaks, ads just make the leak more expensive.

Before you switch anything on:

• Decide who answers the phone during ad hours
• Set up a form notification that actually reaches a human
• Agree an internal target, one hour is a good bar
• Have a holding reply ready for out of hours
• Track calls as well as forms, or you are reading half the data

If the ad says one thing and the page says another, you pay more and convert less. Sending paid traffic to your homepage is the most expensive habit in small business advertising.

The page needs to do one job, and it needs to do it above the fold:

• The headline matches the promise in the ad
• One clear next step, visible without scrolling
• Proof and trust signals near the action, not buried
• Loads fast on a phone, because most clicks are mobile
• A form short enough that someone finishes it in a queue

It probably will be. The first few weeks are Google working out who to show your ads to, and you working out which searches are junk.

Budget for the learning, not just the leads. A test too small to learn from is not a cheap test, it is a wasted one. Give it a fair run and it will tell you the truth either way:

• Enough budget for roughly thirty clicks a week
• Six to eight weeks before you judge it
• Conversion tracking in place from day one, not bolted on later
• A search terms report checked weekly so you can cut the rubbish

If after two months of proper optimisation the cost per customer is still above what a customer is worth, you have your answer. That is a result, not a failure, and it only cost you two months to get it.

The money is usually better spent on the things that make every channel work harder anyway:

• Fixing the pages that already get traffic
• Getting your Google Business Profile earning local visibility
• Building organic visibility that does not stop when you stop paying
• Raising your average order value so the maths changes
• Improving how fast and how well you handle enquiries
• Coming back to ads once one of those has moved
