The honest difference
Google Ads puts you at the top of the results for the searches you choose, starting tomorrow, and charges you for every click. Stop paying and you disappear the same hour. SEO earns you a place in the results that you do not pay per click for, but it takes months to earn and you cannot switch it on for a specific week. One is renting. One is building. Most businesses eventually need both; the question is which one to start with when money and attention are limited.
Start with Google Ads if
- You need customers in the next 30 days. New business, quiet season, a cash-flow problem. SEO cannot help you this month; ads can.
- You do not yet know which searches bring buyers. Two weeks of ads on ten keywords will tell you more than six months of guessing.
- Your offer is time-limited or seasonal. A tax deadline, a holiday product, an event.
- Your market is dominated by huge sites. If page one for your main keyword is all national brands and directories, ads may be the only way onto it for a while.
Start with SEO if
- You can wait six months for the return. The business is stable and you are investing, not rescuing.
- Your customers research before they buy. Professional services, B2B, high-ticket purchases. People searching “best accountant for contractors” want to read, not click an ad.
- You are local. The map pack is free and, for most local services, it is where the calls come from. A good Google Business Profile beats a mediocre ads campaign.
- Clicks in your market are expensive. Legal, insurance, finance and home services can run $20 to $80 per click. At that price a small SEO budget goes further within a year.
A worked example: $2,000 a month for 12 months
Take an illustrative service business: a customer is worth $600 in profit, the site converts 4% of visitors into enquiries, and one in four enquiries becomes a customer. Keywords cost about $3 a click. These are assumptions to show the shape, not a forecast for your business.
| Plan | Months 1 to 3 | Months 4 to 6 | Months 7 to 12 | 12-month customers | After month 12 |
|---|---|---|---|---|---|
| Ads only ($2,000/month) | About 667 clicks a month, 27 enquiries, 7 customers a month | Same | Same | About 80 | Drops to zero when spend stops |
| SEO only ($2,000/month) | Work shipped, roughly 0 to 2 customers a month | Impressions rising, 3 to 5 a month | 8 to 12 a month by month 12 | About 60 | Continues at 10+ a month with lighter spend |
| Split: $1,400 SEO, $600 ads test | Ads bring 2 customers a month and show which keywords convert; SEO targets exactly those | 4 to 6 a month combined | 9 to 13 a month | About 75 | SEO keeps paying; ads can be scaled or cut |
The pattern is what matters. Ads win the first six months. SEO catches up around month eight to ten and then keeps going after you stop paying. The split is rarely the worst option, because the ads test buys the one thing SEO cannot: certainty about which keywords are worth ranking for.
The mistake that wastes both
Sending traffic to a page that does not convert. If your home page has a slider, a paragraph about your passion for excellence and a contact form with nine fields, ads will lose money and SEO will look like it failed. Before either channel, make one page per service that says what you do, for whom, at what kind of price, with proof, and one clear next step. If you want the full list, the seven reasons a site gets traffic but no leads covers it.
How to run the ads test properly
- Pick ten searches a buyer would type, not a browser. “Emergency electrician Dubai”, not “electrical tips”.
- Use exact match or phrase match. Turn off broad match, display network, search partners and “optimised targeting”.
- Send every click to a page built for that search, with the phone number and form above the fold.
- Set up conversion tracking for calls and form submissions before you spend anything.
- Run two weeks. Read which keywords produced enquiries. Those are your SEO targets.
What this means for you
- Local service business: SEO first, specifically your Google Business Profile and one page per service, with a small ads campaign only for your highest-value job type. The map pack is your ads budget’s biggest competitor and it is free.
- E-commerce: ads first for products with a clear margin, using Shopping campaigns; SEO on category pages in parallel because that is where sustainable revenue comes from.
- B2B or SaaS: SEO first on comparison, alternative and use-case pages; a small ads budget on competitor and “software for X” terms to learn, then scale what converts.
A five-question decision score
Answer yes or no. Count the yeses.
- Do I need new customers within 30 days?
- Am I unsure which searches actually bring buyers?
- Is my offer seasonal or time-limited?
- Is page one for my main keyword full of national brands and directories?
- Is a click in my market under $5?
4 or 5 yeses: ads first, SEO from month three. 2 or 3: the split. 0 or 1: SEO first, ads as a two-week test. Whatever the score says, the landing page comes before either.
