SEO or Google Ads: where to invest first

Every business that decides to grow through search hits the same question: do I put money into Google ads or into SEO? One side promises clicks tomorrow. The other promises free clicks, a few months from now. Both salespeople swear theirs is the right one.

The honest answer is that the choice depends on three things: how long your cash can wait, what a click costs in your industry, and what shape the website receiving that click is in. Below are the 2026 numbers and a simple way to decide where to start.

The difference in one sentence

Google Ads is renting. SEO is building.

With ads, you pay for every click. The campaign shows up at the top of search the day it's approved and disappears the day the budget runs out. With SEO, you pay to make the site deserve a spot in organic results, the ones without the sponsored label. It takes a while to start, but the traffic keeps coming after you stop paying.

One thing many people get wrong: neither helps the other's ranking. On its official page about ads on Search, Google states that it only sells ad space, that no one can buy a position in organic results, and that advertisers get no ranking advantage. Spending more on Ads won't move your site up organically.

What a Google Ads click costs in 2026

The most cited reference is the annual LocaliQ and WordStream study, updated in June 2026 with data from thousands of client campaigns on Google Ads and Microsoft Ads. The figures are in dollars and come mostly from the US market, so use them as proportions, not as prices in Brazil:

• Average cost per click: $5.42, up slightly from the previous year.
• Average cost per lead: $66.69. It was the first drop in five years.
• Click-through rate: 6.64%. Conversion rate: 8.18%.

What matters most to whoever is deciding is the gap between industries:

• Lawyers: $9.87 per click and $131.63 per lead, the most expensive in the study.
• Home improvement and services: $8.33 per click and $90.92 per lead.
• Dentists: $8.00 per click and $72.97 per lead.
• B2B services: $5.87 per click and $93.69 per lead.
• Physicians and surgeons: $4.76 per click and $40.04 per lead.
• Real estate: $3.22 per click, but $102.51 per lead.

Real estate shows why looking only at the price of a click is misleading. The click is cheap, but few people who click become leads. The number that matters is what each quote request costs and what a customer is worth.

How the ad budget works

In Google Ads you set an average daily budget. Google Ads Help explains that on a given day a campaign can spend up to twice that amount to catch search peaks. By the end of the month, spending stays below 30.4 times the average daily budget.

In practice: with R$100 a day, expect up to about R$3,040 a month. Now divide that by the cost per lead in your industry. If the math gives you ten leads and you need fifty, ads alone won't hit the goal. If it gives you fifty leads and each customer is worth far more than that, ads pay off fast.

When to start with Google Ads

Ads make more sense first when:

• You need leads this month. A launch, an empty calendar, tight cash. SEO won't solve a 30-day deadline.
• Your margin per customer is high. If a customer pays many times the cost of a lead, every real spent on ads comes back with room to spare.
• You want to test an offer. In a few weeks, ads show which searches bring people ready to buy. That list later becomes your SEO agenda.
• Demand is seasonal. Enrollment, high season, holidays. Ads turn on and off with demand.

For all this to work, the page that receives the click has to be right. Ads that lead to a generic home page, slow on mobile, with no clear action, are budget going down the drain. We explain what that page needs in landing pages for Google Ads and Meta Ads.

When to start with SEO

SEO makes more sense first when:

• Clicks in your industry are expensive. If you're a lawyer, a dentist or in home services, paying $8 or more per click every month adds up. Putting the budget into pages that show up for free tends to pay off more in the long run.
• Your customers research before buying. People hiring an expensive service read, compare and come back. A page that answers their questions works for years.
• You serve one city. Local competition is smaller than national, and Google Maps comes into play.
• You can wait a few months. There's no guaranteed timeline. We show realistic ranges in how long it takes for a website to show up on Google.

The argument that AI killed SEO doesn't hold up in the data either. According to BrightEdge, in September 2025, AI search accounted for less than 1% of referral traffic to websites, and organic search remained the main source of visits. What changed is that the same SEO work now also has to serve AI answers.

What comes before both: the website

Here's the most expensive mistake I see. A business chooses between SEO and Ads without looking at the website that will receive the visits.

• With ads, Google scores the landing page. A slow, confusing page pays more for the same click and converts less.
• With SEO, a site Google can't read, without a good mobile version and without clear answers won't rank, no matter how many months of fees you pay.

That's why the order I recommend is: first the right website, then the traffic source. A fast site, with one page per service and direct answers to what customers ask, serves both ads and SEO at the same time.

What this means for you

Before signing with an ads or SEO agency, answer four questions:

1. What does a lead cost in my industry? Use the averages above as a ballpark and get an estimate from Google's Keyword Planner for your city.
2. What is a customer worth to me? Add up what they pay in the first year. If it's many times the cost of a lead, ads pay for themselves.
3. How long can my cash wait? If the answer is less than three months, start with ads.
4. Is my website ready for visitors? If the answer is no, neither will deliver.

If the budget allows both, the most common path is to use ads to bring in leads now and find out which searches convert, while SEO builds traffic that doesn't depend on budget. If the budget only covers one, choose based on your answer to question 3. To compare SEO proposals, see also how much SEO costs a business per month.
