SEO vs Google Ads: Where Should You Start?
Both work. They just work on different timelines, with different money, and they fail for different reasons. Here is how to decide which one deserves your budget first, and when running both actually makes sense.
Start with Google Ads if you need enquiries inside 90 days and can fund a proper test budget. Start with SEO if you have 6 to 12 months of runway and want traffic that keeps arriving after you stop paying. For most Australian small businesses the honest sequence is ads first, SEO second, and both running together by roughly month four.
What is the real difference between SEO and Google Ads?
Google Ads is rented attention. You bid, you pay per click, and the day your card gets declined the phone goes quiet. SEO is attention you own. You put money into pages, technical fixes and links, and once a page ranks it keeps producing enquiries in months where you spend nothing at all.
Neat distinction, and mostly true, but it skips over the thing that actually decides the answer for you: your cash position and your time horizon. A plumber who needs jobs booked for next month has no business waiting on a content plan. A specialist consultant with a full pipeline and 12 months of patience is burning money paying $45 a click for terms they could own outright inside a year.
We build and run both for clients, so there is no barrow being pushed here. What follows is what we tell people who ring up and ask.
How do SEO and Google Ads compare on cost, speed and control?
Ads win on speed, targeting control and testing. SEO wins on cost over time, durability and how much users trust the result. This is how the comparison plays out in practice rather than how it gets pitched in a sales meeting.
| What you care about | Google Ads | SEO |
|---|---|---|
| Time to first lead | Days. A campaign built on a Monday can produce enquiries by Thursday. | Three to six months for softer terms, six to twelve for anything with real money behind it. |
| Cost behaviour over time | Flat or rising. More competitors bidding pushes cost per click up, so cost per lead tends to creep. | Front loaded, then falling. The same retainer buys more traffic each quarter as pages mature. |
| What happens when you stop paying | Traffic stops that day. There is no residual, none. | Rankings hold for months, then slide slowly as competitors keep publishing. You keep the asset. |
| Control over targeting | Very high. Suburb, device, time of day, exact phrase, and negative keywords to block the rubbish. | Limited. You influence what you rank for; Google decides. Local results are partly geography, not choice. |
| Trust from users | Lower. Plenty of buyers scroll straight past anything marked Sponsored, particularly in legal, finance and healthcare. | Higher. A first page organic listing reads as earned rather than bought. |
| Value as a testing tool | Excellent. Real conversion data on real search phrases within four to six weeks. | Poor. You find out whether a keyword converts about a year after you committed to it. |
One row in that table does more work than the rest, and almost nobody talks about it. More on the testing line shortly. If you want the mechanics of how ranking work actually gets done month to month, our approach to SEO for Australian businesses spells out what a retainer buys.
Which one should you start with?
Answer five questions honestly. It takes about five minutes and it beats any general rule, including ours. Write the answers down, because the pattern usually becomes obvious by question four.
- How many months can you fund marketing before it has to pay for itself? Under four months and you need ads. Nine months or more and SEO can lead the charge.
- What is a customer actually worth? If a job averages $300 and clicks in your category run $18, the maths is brutal and ads may never clear. If a client is worth $5,000 or more over their life, paid search almost always works.
- Do people search for what you sell at all? Nobody types “innovative brand storytelling partner”. They type “logo design Sydney”. If the phrases do not exist, neither channel saves you and you need referrals or social.
- How good is your website right now? Sending paid traffic to a site that takes seven seconds to load and hides the phone number is setting fire to money. Fix the page before you buy the clicks.
- What does the organic first page look like for your main term? If it is three directories, two national franchises and a Reddit thread, that is a long war. If it is thin local sites with 400 word service pages, that is an opening.
Rough scoring. Short runway, high customer value, decent website: ads first. Long runway, modest customer value, weak competitor pages: SEO first. Everyone in between should run ads to buy time while SEO gets built underneath, which is where most of our clients land.
A rule of thumb worth stealing. If your average customer is worth less than about $400 excluding GST and your category’s clicks cost more than $15, do the arithmetic on paper before switching ads on. At a 5 per cent conversion rate that is $300 of clicks per sale before you have paid for management, materials or your own time. Some businesses genuinely cannot make paid search work, and any agency that will not say so out loud is not worth hiring.
Why is Google Ads the fastest way to find out which keywords are worth ranking for?
Because ads tell you which search phrases produce paying customers, and they tell you in weeks rather than in a year. This is the most undersold reason to run paid search, and it is the one experienced marketers quietly rely on.
SEO forces you to commit early. You pick target keywords in month one, build pages around them, earn links to them, and then wait. If you picked wrong, you find out in month eleven, having spent maybe $15,000 excluding GST ranking for terms that bring browsers rather than buyers.
Ads collapse that feedback loop. Run $2,000 of spend across fifteen phrases for six weeks and the search terms report will show you, with actual conversion data, which four are worth owning. We had a hot water business convinced their money term was “emergency plumber”, the phrase they had been chasing organically for two years. Six weeks of paid search said otherwise: “hot water system replacement” and “instant gas hot water installation” converted at nearly three times the rate, at half the cost per lead. That changed the entire content plan, and it cost less than one month of SEO retainer to learn.
Do it in that order and your SEO investment stops being a guess. That is the argument for running a managed Google Ads campaign even if your long term plan is entirely organic.
When does it make sense to run both?
Once you can afford roughly $2,500 a month excluding GST across both, run both. Below that, split budgets usually produce two half efforts and no results. Above it, the two channels genuinely feed each other.
There are also specific situations where both is not optional:
- Competitors bidding on your business name. It happens more than owners realise, and defending your own brand term is cheap because your quality score on your own name is high.
- Seasonal spikes. Tax time for accountants, storm season for roofers, January for gyms. Organic rankings cannot be dialled up in a fortnight; ads can.
- Service pages that will realistically never rank. Some terms are locked up by aggregators and national brands. Buy those clicks and put your organic effort where you can actually win.
- New suburbs or a second location, where you have no local signals yet and no reviews to speak of.
The other benefit is measurement. When ads and organic run together you can see which pages convert regardless of how the visitor arrived, which makes the whole marketing budget easier to defend. Plenty of the related questions in our SEO section of the Knowledge Centre deal with the tracking side of this.
How should you split a $1,500, $3,000 or $6,000 monthly budget?
At $1,500 put nearly all of it into ads. At $3,000 run both, weighted to ads. At $6,000 you can run a genuine dual channel programme with content behind it. Figures below exclude GST and include management fees, because pretending management is free helps nobody.
| Monthly budget (ex GST) | What we would do | Reasoning |
|---|---|---|
| $1,500 | About $1,050 ad spend, $450 management. No SEO retainer, but fix titles, service pages and your Google Business Profile once as a project. | Splitting this in half gives you a campaign too small to gather data and an SEO effort too small to move anything. Pick one and do it properly. |
| $3,000 | Roughly $1,800 to ads (spend plus management) and $1,200 to SEO. | Ads keep the pipeline alive and tell you which terms convert. The SEO retainer targets exactly those terms instead of guessing. |
| $6,000 | Around $3,000 to ads, $2,200 to SEO, $800 to content and conversion work on the site itself. | At this level the constraint is usually the website, not the traffic. Lifting conversion from 2 to 3.5 per cent is cheaper than buying 75 per cent more clicks. |
Two caveats. Ad spend needs to be big enough for the campaign to learn, and in most Australian service categories that floor sits somewhere near $1,000 a month; below it Google’s bidding algorithms never get enough conversions to optimise against. And be wary of anyone quoting SEO at $400 a month. That buys about two hours of a competent person’s time, which is not a strategy, it is a report.
What should you do if you can only afford one?
Pick ads if you need revenue this quarter. Pick SEO if you have money coming in already and want to reduce what you pay per lead over the next two years. There is no third answer that isn’t a fudge.
If you go the ads route, do not neglect the free end of SEO while you wait. Claim and fill out your Google Business Profile properly, get reviews coming in steadily, write one genuinely good page per service rather than six thin ones, and make sure the site loads fast on a phone on mobile data. That work costs time rather than retainer money and it compounds. Plenty of tradies and clinics get most of their organic leads from the map pack alone, without ever paying for a formal campaign.
If you go the SEO route, accept the timeline honestly. Anyone promising first page in 30 days is either targeting phrases nobody searches for or telling you something the ACCC would take a dim view of. Nobody can guarantee rankings, us included, because we do not control the algorithm. What we can do is commit to the work and show you what changed each month, which is how our ongoing SEO retainers are structured.
The pattern we see most often across 20 years of doing this: ads switch on in month one, the first honest keyword data lands by month two, SEO starts in month three aimed at proven terms, and by month nine the organic side is carrying enough of the load that ad spend can be pulled back or pointed at new services. That is not the only path, but it wastes the least money.
Common questions
Is SEO actually cheaper than Google Ads in the long run?
Usually yes, for businesses that stay in the game more than two years. A page ranking well delivers clicks at no marginal cost, so your cost per lead falls every quarter the traffic grows. Ads charge you the same or more per click forever. The catch is the first six to nine months, where SEO costs money and returns nothing measurable. Businesses that quit inside that window get the worst of both.
Can I run the SEO myself while paying someone to manage the ads?
Yes, and it is a sensible split for a hands on owner. The parts you can genuinely do yourself are content, reviews, Google Business Profile upkeep and answering customer questions on your service pages. The parts that go wrong without experience are technical setup, site structure and link building. Ads management is harder to self teach because mistakes cost real money daily, whereas a slow SEO month costs you time.
How much should I spend on Google Ads before deciding it does not work?
Give it enough spend to generate at least 30 conversions, or three months, whichever comes first. In a category with $10 clicks and a 5 per cent conversion rate that is roughly $6,000 excluding GST. Stopping at $800 and two weeks tells you nothing except that two weeks is not long enough. If you cannot fund a real test, do not start one.
Does running Google Ads improve my organic rankings?
No. Google has been clear that paid spend does not directly influence organic position, and we have never seen evidence otherwise. The indirect effects are real though. Ads bring visitors who later search your brand name, they surface which keywords convert so your SEO targets better, and they generate the conversion data that makes landing page improvements obvious. Helpful, but not a ranking factor.
If I stop paying an SEO agency, do my rankings vanish?
Not immediately. Well built pages typically hold their positions for several months, then drift down as competitors publish more and earn links you no longer match. Technical decay also creeps in after WordPress and plugin updates. Think of it as a building you stop maintaining rather than a light switch. Many clients pause SEO for a quarter without disaster; pausing for two years is a different story.
Should a brand new business with no website traffic start with ads?
Almost always, provided the website is decent and the customer value supports the click cost. A new site has no rankings, no reviews and no authority, so organic traffic is months away at best. Ads give you customers, cash flow and, importantly, evidence about which services people actually want. Use the first three months of ad data to decide what the SEO plan should target.
