Every business owner I talk to has the same question about Google Ads. Should I be running them? And the answer is almost always the same: not yet.
That doesn’t mean ads don’t work. They absolutely can. But most local service businesses skip the free stuff that would get them more customers for less money, then dump $2,000 a month into ads and wonder why it’s not working.
Let me break down when ads make sense, when they don’t, and how to think about the tradeoff between paying for clicks and earning them.
When Google Ads make sense
You just opened your business. SEO takes time. A new Google Business Profile needs months to build authority and reviews before it ranks in the Map Pack. If you need leads now, ads are the bridge. Run them while you build your organic presence, then dial back once you’re ranking.
You have a seasonal spike. Roofers after hail season. HVAC companies in July. Pool builders in spring. If there’s a 6-8 week window where demand surges and you need maximum visibility, ads let you capture that demand without waiting for organic rankings to catch up.
You’re in a hyper-competitive market. In some metros, the Map Pack for popular searches is dominated by companies with hundreds of reviews and years of SEO investment. If breaking into the top three organically will take a year, ads can get you visible while you close the gap.
You want to test a new service area. Thinking about expanding to a neighboring city? Run ads targeting that zip code for 60 days and see if the leads justify the expansion before you commit.
When Google Ads are a waste of money
You haven’t fixed the basics. If your Google Business Profile is half-empty, you have 8 reviews, and your website doesn’t mention your services or service areas, ads will send people to a digital presence that doesn’t convert. You’re paying to drive traffic to a dead end. Fix the foundation first.
You’re running ads instead of building organic. I’ve talked to business owners spending $3,000/month on Google Ads who haven’t posted a single update on their Google Business Profile in two years. They’re renting visibility instead of building it. The day they stop paying, they disappear. That’s not a marketing strategy. That’s a subscription to leads.
Your budget is too small to learn. Google Ads require enough spend to generate data. If you’re spending $300/month, you might get 10-15 clicks. That’s not enough to know what’s working. You’ll optimize based on randomness and conclude “ads don’t work” when really you just didn’t spend enough for the algorithm to find your customers.
Nobody is searching for what you offer. Ads work when there’s existing demand to capture. If you’re offering a service people don’t know they need, search ads won’t help because nobody’s searching for it. You’d need awareness marketing, which is a completely different playbook.
The real cost per lead
Here are some rough numbers from service businesses I’ve worked with and industry data from WordStream’s research. These are cost per lead, meaning the cost to get someone to call or fill out a form. Not the cost per click, which is a different and less useful number.
Home services like plumbing and HVAC typically run $30-80 per lead through Google Ads. Roofing and construction are higher, usually $50-150 per lead because the keywords are more competitive. Legal services can hit $100-300 per lead. Medical and dental run $30-60.
Now compare that to organic search leads. Once you’re ranking in the Map Pack, your cost per lead from organic search is effectively zero. You’re not paying per click. Every call that comes in from your Google Business Profile is free. The only cost is the time or money you spent building up your profile and reviews.
That’s the fundamental math. Ads give you leads now at $50-150 each. SEO gives you leads later at close to $0 each. The best approach depends on where you are in your business.
The hybrid approach that actually works
Here’s what I recommend for most local service businesses.
Months 1-3: Ads plus foundation building. Run a modest ad budget, maybe $500-1,000/month, targeted at your highest-value services. Simultaneously, fix your Google Business Profile, start getting reviews consistently, and make sure your website actually converts. Use the ad spend to generate leads while the organic work starts compounding.
Months 4-6: Organic starts kicking in. If you’ve been getting 4-5 new reviews per month and posting weekly updates, you should start seeing your organic rankings improve. Watch your Google Business Profile insights. When organic calls start rising, begin reducing ad spend proportionally.
Month 7 and beyond: Strategic ads only. At this point your organic presence should be generating consistent leads. Only run ads for specific situations: a seasonal push, a new service launch, or a competitive keyword where you haven’t cracked the top three organically yet.
The goal is to use ads as a tool, not a crutch. If you’re still spending the same amount on ads a year from now with no organic growth, something went wrong with your strategy.
The question to ask your marketing company
If you’re working with someone who manages your ads, ask them this: what are you doing to reduce my ad spend over time?
If the answer is nothing, they’re incentivized to keep you spending. Their fee is usually a percentage of your ad budget. The more you spend, the more they make. A good marketing partner should be actively building your organic presence so you depend less on paid traffic over time.
That’s the difference between renting customers and owning your presence.
