Google Ads brings calls this week but stops the moment you stop paying. SEO takes a few months to build but keeps bringing calls without paying for each click. For most contractors and home-service businesses, the best answer is not one or the other: use ads (or Local Services Ads) for leads now, and SEO to lower your cost per job over time.
Key takeaways
- Google Ads is fast and controllable, but every click costs money.
- SEO is slower to start, but rankings keep bringing calls once earned.
- Local Services Ads charge per lead and show above normal ads for many trades.
- Most searchers click organic results and the Map Pack more than ads.
- A good website makes both work better: it is where ad clicks and SEO visitors decide to call.

How Google Ads works for contractors
With Google Ads you bid on searches like "roof repair near me". When someone clicks your ad, you pay. You control the budget, the towns you show in and the hours your ads run, so it is the fastest way to turn on the phone.
The catch is cost. In competitive trades such as roofing, plumbing or HVAC, clicks can be expensive, and not every click becomes a call. Without a page built to convert, you pay for visitors who leave.
Local Services Ads
For many home-service trades, Google also offers Local Services Ads, the listings that can show a "Google Guaranteed" or "Google Screened" badge at the very top of results. You pay per lead rather than per click, and you need to pass Google's background and licence checks. They are worth testing alongside normal ads.
How SEO works for contractors
SEO means ranking in the normal results and the Map Pack without paying for each visit. For a local service business that comes down to:
- A fully optimised Google Business Profile
- A website with a page for each service and each main town you serve
- A steady flow of genuine reviews
- Mentions and links from local and industry websites
It takes longer to build, but once a page ranks it can bring calls every month. That is why SEO usually wins on cost per job after the first several months. See our SEO for contractors page for how we approach it.
Which one should you choose?
Choose Google Ads first if:
- You are a new business and need jobs this month.
- Your website and Google profile are brand new and will take time to rank.
- You want to test which services and towns bring the best jobs.
- You have a seasonal rush to fill, such as storm season for roofers.
Choose SEO first if:
- You want a lower cost per job over the next year.
- Your competitors rank organically and you keep losing jobs to them.
- You are already paying a lot for ads and want to reduce that spend.
- You plan to be in business in the same area for years.
The strongest approach for most contractors: run ads for immediate leads while SEO builds, then reduce ad spend as organic rankings and Map Pack positions take over.
Using both together
Ads and SEO help each other. Ad data shows which keywords bring real jobs, so you know which pages to build for SEO. Strong organic rankings mean you can stop bidding on terms you already win. And both send people to the same place: your website.
If that website is slow, has one generic services page, or hides the phone number, both ads and SEO underperform. A fast service business website with a quote form and click-to-call on every page is the foundation for either channel.
How to measure which is working
- Track calls and form submissions separately for ads and organic search (call tracking numbers and Google Analytics help).
- Compare cost per lead and, better, cost per booked job, not cost per click.
- Check Google Search Console for organic impressions and clicks growing month by month.
- Ask every new customer how they found you.
SEO vs Google Ads questions
Is SEO or Google Ads better for contractors?
Google Ads is better for fast leads; SEO is better for lower cost per job over time. Most contractors get the best results by running ads while SEO builds, then shifting budget to SEO as rankings grow.
How long does SEO take compared to Google Ads?
Ads can bring leads within days. SEO usually takes 3 to 6 months to rank for main service keywords in a city, depending on competition.
What are Local Services Ads?
Google ads for home-service businesses that show at the top of results, often with a Google Guaranteed or Google Screened badge. You pay per lead instead of per click and must pass Google's checks.
Can I stop Google Ads once SEO is working?
Many businesses reduce ad spend once they rank well for their main services, and keep ads only for competitive terms, new towns or busy seasons.
