Google Ads or SEO: which to choose and when you need both

Someone types “washing machine repair at home” into Google and sees two groups of results. At the top are ads marked “Sponsored”. Below them are the regular results. You get into the first group through Google Ads and into the second through SEO, which means working on the website itself.

The choice between them is often framed as an argument about which is better. In reality they’re two different tools that work in different ways: one switches on fast and costs money for as long as it runs; the other takes a long time to build up but accumulates results. The right answer depends on where your business is right now.

Let’s look at how these channels differ, when to start with one and when with the other, and why most businesses end up needing both.

The difference in one comparison

Google Ads is like renting a stall on a busy street. You pay, you’re seen. Stop paying, and someone else takes the spot and you’re forgotten the same day.

SEO is like building your own shop. It takes time and investment before the first customers arrive, but then the premises are yours. You can’t stop investing altogether, since the neighbors are building too, but the flow of people doesn’t stop the moment you stop paying.

That leads to three practical differences.

Speed

Google Ads starts showing your ads once they’ve passed Google’s review. The first leads can come in within days. SEO brings noticeable changes over months: Google needs to recrawl the site and evaluate the changes, and people need to start clicking through.

Money

With Google Ads you pay Google for clicks or for conversions, depending on the bidding strategy you choose, plus a fee for setting up and managing the campaigns. With SEO you pay for work on the website, and clicks from the regular results are free.

What stays

When you stop advertising, you’re left with data: which searches brought leads, which ads worked. When you stop SEO, you’re left with pages, copy and rankings. They gradually slip, but they don’t vanish overnight.

When to start with Google Ads

Advertising is the right first step if you need results fast or want to test something:

• A new business or a new website. A young site has no history in search, and organic traffic will take a long time. Ads bring in leads while search picks up speed.
• A season or a promotion. Air conditioners in summer, Christmas tree lots in December, a two-week sale. SEO won’t get there in time.
• Testing demand. You want to launch a new service but aren’t sure people will buy it. A small ad budget will show whether there’s interest before you invest in a full section of the website.
• A new city. You’ve opened a new location, and ads can be shown only to people in that area.

One thing matters here: ads send people to your website. If the site is awkward on a phone, the form doesn’t work and prices are nowhere to be found, you’re paying for clicks from people who leave right away. Sometimes it’s better to build a landing page for the ads first and launch the campaigns after.

When SEO comes first

Search moves to the front when:

• Customers take a long time to decide. Home renovation, education, equipment. People read, compare, come back. A website that answers their questions works at every stage of the decision.
• You have many services and many searches. Each service gets its own page, and each page picks up its own searches. Running ads on hundreds of phrasings is expensive and complicated, while pages keep working all the time.
• Ads in your field are expensive. In competitive niches a click can cost real money, and every lead from ads comes at a high price.
• You’re in it for the long run. SEO is an investment that pays off over time.

Alongside SEO there’s now GEO, which is work on AI answers. More and more people ask ChatGPT or Gemini “who would you recommend”, and these models build their answers from the same sources search engines see. You can’t buy a place in that answer the way you buy a click in Google Ads: you get there through your website’s pages, mentions and reviews. That’s why we run SEO and GEO together.

When you need both

For most businesses that plan to be around for more than one season, the answer is both channels, just with different weight at different times. That’s why we set up Google Ads and website promotion as one piece of work, with shared goals in Google Analytics.

A typical setup looks like this. In the first months, Google Ads brings in most of the leads while work on the website goes on in parallel. As rankings grow, some searches start bringing people in from the regular results. Then the ad budget can be redistributed: kept where search can’t yet cope, and for seasonal peaks.

The channels help each other:

• Google Ads gives SEO data. Ads quickly show which searches bring leads and which bring only clicks. Those are the searches to build pages for first.
• SEO improves your ads. Pages built for specific services also work as landing pages for ads: people land straight on the service they need, not on the homepage.
• People see you twice. An ad at the top and your site in the results below adds confidence when they’re choosing.

What if your business is local

For a café, salon, car service or clinic there’s a third channel people often forget: Google Maps. When someone searches for something “near me”, they see the map and business listings before the regular results. For a local business, a complete, active profile with photos, prices and replies to reviews is often more important than the website. We manage Google Business Profiles for $90 a month.

How to tell what’s working

Comparing channels by gut feeling is pointless. You need numbers:

1. Conversions in Google Analytics. Form submissions, taps on the phone number, clicks through to a messenger: all of these should be counted.
2. UTM tags on ad links. So that Google Analytics can tell leads from Google Ads apart from leads from search.
3. Cost per lead. For ads, the budget plus management divided by the number of leads. For SEO, the monthly cost of the work divided by the number of leads from search. Compare over a long period: SEO delivers results with a delay.
4. Lead quality. Not just how many, but how many became customers. That’s easiest to track in a CRM.

Common mistakes

• Launching Google Ads to a website that’s awkward to use on a phone.
• Expecting SEO results after one month and giving up in the third.
• Sending all ads to the homepage instead of pages for specific services.
• Not setting up conversions and then guessing where customers came from.
• Dropping ads entirely as soon as the first rankings appear, while search doesn’t yet cover all the demand.

Key takeaways

• Google Ads brings leads fast, but only while you pay; SEO takes months to build up but accumulates results.
• Start with Google Ads if your site is new, you have a season, or you need to test demand.
• SEO comes first when customers take a long time to decide, you have many services, or ads in your field are expensive.
• Most businesses need both channels: ads feed you now, search grows for the future, and they give each other data.
• Our SEO + GEO is $390 a month; Google Ads management is $390 a month, with the ad budget paid to Google separately.
