Google Ads vs SEO: Which Is Right for Your Business?

Our clients at Futuretheory often ask if Google Ads or Search Engine Optimisation (SEO) is the best solution for them. Like many other business questions, there isn’t a universal cut-and-dried answer. The right choice for you depends on your business’s maturity, its current needs, and what investments of time or money it can sustain over the long term. Consider this post a practical guide to help you make that call. We’ll look at the differences between SEO and Google Ads, when to prioritise one over the other, how to use both, and what’s needed in terms of expertise and time.

How Google Ads works

Google Ads looks at demographics, interests, and geographic location to target its ads to your ideal audience. Google uses that information to display ads to that audience on Search Engine Results Pages (SERP) and the Google Display Networks, which includes YouTube, Gmail, and millions of websites. With good creative and the right targeting, Google Ads can be a powerful tool to send traffic to your website.

Google Ads cost

While Google has different models for paid advertising, you generally pay each time someone clicks on your ad. The payment is the same whether the user converts or not. In the search results, paid ads appear above organic search results. The benefit of Google Ads is immediate visibility, but that visibility stops the moment you stop paying, meaning it can get costly over time.

Cost-per-click (CPC)

The average cost-per-click (CPC),  is currently between $2 and $4 in Australia, but costs vary a lot by industry. In competitive industries like law, medicine, and finance, the costs can rise to between $10 to $50 per click. Google Ads campaigns can be highly targeted by location, device, time of day, and search intent.

How search engines work

Understanding SEO is easier if you understand how search engines like Google work. They use bots that read through (or ‘crawl’) web pages on the internet. Google and other engines collect information to index web pages by both quality and authority. How well does this content answer common user search queries? How many other reputable sites link to this page? Links from other websites signal to Google that people find this content valuable, which raises a site’s authority in the engine’s eyes. Google and others use algorithms that change regularly, which is why SEO isn’t a one-time task but an ongoing one that needs a long-term strategy.

How SEO works

SEO strategies improve your website’s technical performance, use of particular keyword terms, and overall content so your pages are more likely to appear higher in search results. When potential customers use search engines, most look only at the first page of results, so rankings matter. The higher you rank, the quicker your target audience finds you.

Building that authority takes time: it comes from stronger content, better links, and a technically sound site, which together attract more organic traffic. For many search queries, organic results also tend to earn higher click-through rates and greater user trust than paid ads.

When you invest in SEO

SEO doesn’t have a cost per click, but it requires expertise and consistency to get results.This is one of biggest cons of SEO. Google Ads can provide immediate visibility, but good SEO builds something more durable: authority and rankings that compound over time. Most businesses see meaningful movement at the 6 to 12 month mark, with returns that grow beyond that.

Unlike Google Ads, rankings built through SEO practices don’t disappear the moment you stop paying. However, because of changing algorithms and competition, SEO relies on continuing effort to maintain results. 

Now let’s look at choosing between SEO and Google Ads.

When to prioritise Google Ads

Using Google Ads tends to make more sense for a business when:

• It’s just starting out and can’t wait 12 months for leads; use Google Ads for immediate results.
• A product is launching, a campaign is rolling out, or there’s a time-sensitive offer.
• It operates seasonally and needs visibility during peak periods.

When to prioritise SEO

Using SEO tends to make more sense for a business when:

• It has a 12- to 24-month runway and wants to build a long-term asset.
• Margins are tight, so sustaining an ongoing ad spend isn’t viable.
• It’s established and wants to reduce reliance on paid channels over time.
• Building brand credibility and authority is a priority.

Google Ads and SEO – time and expertise needed

Is it feasible for a business to undertake in-house Google Ad campaigns or SEO efforts? Both strategies require more time and expertise than most business owners expect. 

Google Ads

Setting up a campaign is straightforward, but running one well is not. Keyword selection, keyword bidding strategy, ad copy, landing page quality, and ongoing optimisation are all specialties that require time and expertise. 

Poorly managed Google Ads campaigns burn through budget quickly as problems include. These problems can include:

• Broad keywords pull in irrelevant searches.
• Ads don’t match what users want to do.
• Conversion tracking isn’t set up correctly, so the data is unreliable.
• Clicks are prioritised rather than conversions.
• Landing pages aren’t converting users to customers.

Most businesses that try to run their own ads without experience find the results disappointing.

SEO

SEO requires technical knowledge about how search engine results work, the ability to develop a winning content strategy, and consistent effort over a long period. SEO is not a set-and-forget exercise – SEO is a long-terms straregy. Algorithm changes, competitor activity, and content gaps all require continuous monitoring and ongoing attention to adapt and improve rankings. 

Poorly managed in-house SEO can also result in:

• Content that’s not relevant to the user
• Slow load speed, broken links, unclear navigation, or no mobile responsiveness because of a lack of expertise in technical SEO
• A lack of quality backlinks that help to establish credibility
• Penalties from keyword stuffing or buying links in an effort to improve search rankings

It’s rare for the average business to have all the types of expertise needed to handle SEO effectively. The time investment alone makes it difficult to manage in-house without someone dedicated to it.

What about hiring an expert?

Because of the range of expertise needed and the sheer amount of time involved, neither channel is especially well-suited to a DIY approach for most businesses. Both are more likely to deliver results when managed by someone who does SEO services, digital marketing, or advertising full-time.

Using SEO and Google Ads together

For many businesses, rather than choosing SEO or Google Ads, the most effective approach is often to use both channels together, sequenced correctly. Here’s one way that might work. 

You can use Google Ads to generate leads immediately, while SEO builds long-term results in the background. Over time, as your search engine rankings improve thanks to SEO, you can gradually reduce the Google Ads spending.

How to decide on Google Ads vs SEO

Deciding which channel to use first and how to sequence them depends on where your business is right now. Some key questions to ask yourself are:

• How quickly do you need results? 
• How much effort can you sustain over the long term?
• Does your team have the expertise and time required for a well-executed SEO campaign? 
• What does your competitive landscape look like? 

Futuretheory’s take

We don’t have a stock answer about Google Ads versus SEO because what’s right for your business depends on your goals and particular situation. A new business with an immediate need for leads is in a different position from an established business looking to reduce its reliance on paid channels. A business that fills an underserved niche is different from one in a highly competitive market.

Unlike digital marketing agencies that push the marketing strategy they prefer to sell rather than the service that suits the client, our advice is always tailored to you and your particular situation. Choosing between these channels is easier with an agency that has the expertise and takes the time to know your business.
