Is SEO Worth It for a Small Business?
A frank look at the payback maths on an SEO retainer, including the situations where we tell business owners not to bother.
SEO is worth it if you sell something people search for repeatedly, you can wait six to twelve months for the return, and one client is worth more than a few hundred dollars to you. On a $1,500 a month retainer excluding GST, most Australian trade and professional services businesses need roughly one extra client a month to break even. Below that, it isn’t.
That version has a fail condition in it, which is why you rarely hear it from an agency. We have been looking after Australian business websites since 2004 and we have talked plenty of people out of SEO. Not because it doesn’t work. Because it was the wrong spend for that business, that month, with that sales process. Here is the arithmetic, then the cases where it doesn’t land.
What does the payback actually look like?
Work it in gross profit, not revenue, and over twelve months rather than one. Take a business we see constantly: a commercial and domestic electrician in Western Sydney, three vans, wanting work that isn’t builder referrals.
Average job invoices at about $2,400. Gross margin after materials and labour sits near 45 per cent, so roughly $1,080 per job. A decent proportion come back and some refer, so lifetime gross profit per new client lands closer to $1,700 across three years. Enquiry to booked job runs about 40 per cent when someone actually answers the phone.
They spend $1,500 a month excluding GST. Nothing meaningful happens in months one to three. Small movement around month four or five, first genuine enquiries around month six, run rate settling in months nine to twelve. Twelve months in, they are $18,000 down.
To get that back they need about eleven new clients from organic search over the year, which is 27 enquiries, a bit over two a month. For an electrician covering a handful of Sydney suburbs, that is achievable. Not guaranteed, and anyone who guarantees it is a problem, but achievable. That is the whole test.
What is the break even at different retainer levels?
The higher the retainer, the more customers it has to produce every month, and the maths gets steep faster than people expect. Same assumptions as above: $1,700 lifetime gross profit per client, 40 per cent enquiry to job.
| Monthly retainer (ex GST) | 12 month spend | New clients needed to break even | Enquiries needed | Enquiries per month |
|---|---|---|---|---|
| $750 | $9,000 | 5.3 | 13 | 1.1 |
| $1,500 | $18,000 | 10.6 | 27 | 2.2 |
| $2,500 | $30,000 | 17.6 | 44 | 3.7 |
| $4,000 | $48,000 | 28.2 | 71 | 5.9 |
Read the bottom row carefully. At $4,000 a month you are asking search for six qualified enquiries every month just to stand still. If your city has 300 people a month typing the relevant phrases, fine. If it has 60, you have bought a retainer your market cannot pay for.
How do you work out your own numbers?
Four figures, half an hour with your accounting file open.
- Average sale value and the gross margin on it. Revenue is a vanity number here; use what is left after you have paid to deliver.
- How often a client comes back, and over how long. A physio has repeat visits baked in. A conveyancer might see someone twice in a decade.
- Your enquiry to sale conversion rate. Be honest. Most owners guess 60 per cent and the real figure, once you count the calls nobody returned, is closer to 30.
- How many people search for what you do, in your area, each month. Free Google Keyword Planner numbers are rough, but they will tell you whether it is 40 searches a month or 4,000.
Multiply the first two for lifetime gross profit. Divide annual SEO spend by that for your break even client count, then divide by your conversion rate for the enquiry count. If that number is more than about a quarter of monthly search volume in your area, walk away. Nobody gets a quarter of a market.
Rule of thumb we use internally: if the annual spend is more than 20 per cent of the gross profit it would need to generate in year one, we suggest a smaller scope or a different channel. We would rather do $900 a month of useful work for three years than $3,000 a month for five months before you pull the plug.
When is SEO not worth it?
Five situations where we say no, or at least say wait. They cover most of the unhappy SEO stories we hear.
Nobody is searching for what you sell
Some things have real demand and tiny search demand. Specialised B2B equipment, a genuinely new service category, a niche where buying happens through industry contacts and tenders. If the entire relevant keyword set adds up to 90 searches a month nationally, the ceiling is low no matter how good the work is. Ranking first for something nobody types is an expensive form of vanity. LinkedIn outreach or direct sales will do more.
You need cash this month
SEO is a poor answer to a cash flow problem. Six months of spend before meaningful return is the normal case, not the pessimistic one. If your runway is short, put the money into Google Ads where you can be in front of buyers this afternoon, or into ringing your last two years of customers. We have had clients start SEO while quietly panicking about payroll, and it ends badly for everyone.
It is a one off purchase with no repeat market
If someone buys once in their life and never refers anyone, lifetime value equals a single transaction and the table above gets brutal. Some categories genuinely are like this. The honest fix is rarely more SEO; it is adding a service the customer needs later, or a referral mechanic, so the same acquisition cost buys more revenue.
Your sales process leaks
This is the one that stings. If enquiries go to an inbox someone checks on Thursdays, or the phone rings out at 3pm on a job site, more traffic just means more leaks. We have audited businesses losing half their enquiries before anyone spoke to a human. Fixing that costs almost nothing and lifts the return on every marketing dollar afterwards. Missed call text back, a shared inbox with an owner, a two hour response standard: unglamorous, and worth more than three months of link building.
The site needs rebuilding, not optimising
Occasionally a site is beyond economical repair. A page builder theme abandoned in 2016, three seconds of render blocking scripts, no sensible URL structure, content locked inside images. Pour SEO into that for a year and you are mostly funding workarounds. We would rather quote a rebuild than take a retainer that cannot perform, and our page on what an SEO engagement includes sets out what it assumes about your site.
What else could that money do?
Every SEO dollar competes with three or four other uses, and sometimes it loses fairly. Google Ads buys attention today at a known cost per click, which suits testing whether a service sells before you commit twelve months to ranking for it. A Google Business Profile that is filled out properly and collecting reviews will often out-earn early SEO work for a local trade, and it is close to free. Email to your existing list is the cheapest revenue most service businesses have, and nearly everyone ignores it.
Our usual sequence under about $1.5m turnover: fix enquiry handling, sort the Google Business Profile, run a small Ads budget to prove the offer converts, then start SEO with what you learned.
Does SEO really compound, or is that a sales line?
It compounds, but not the way it gets sold. What compounds is the asset: pages that keep earning after you stop paying, authority that makes each new page rank faster than the last, links that accumulate. A professional services client of ours stopped active SEO in 2021 and their organic enquiries only slid meaningfully in late 2023. That tail is the real argument for SEO over ads, where traffic stops the day the card declines.
The honest limits. Compounding assumes your competitors stand still, and in Sydney trades and legal they do not. It assumes Google does not restructure the results page for your query, which it does, sometimes annually. And it assumes the content stays accurate; a 2022 pricing guide with 2022 numbers decays quietly. Content depreciates. Treat it like a ute, not like land.
Do AI answers in search change whether SEO is worth it?
Yes, and mostly for informational searches rather than buying ones. When someone asks Google or ChatGPT what rewiring a house costs, they increasingly get the answer without clicking anything. Traffic to broad explainer content has fallen for a lot of sites, ours included. We would be lying if we said otherwise.
What has not changed is the person typing “emergency electrician Parramatta” at 7pm. They want a phone number and a human, and that intent still produces a click. So the money moves: less into thin articles chasing volume, more into service pages, local pages, reviews, and being the source an AI answer cites. A mention in an AI summary is worth something without the click, though nobody measures it properly yet, so be sceptical of anyone selling you a metric for it. More on that across the rest of our SEO articles.
How do you buy SEO without getting burned?
Most bad SEO experiences trace back to the purchase, not the work.
- No lock-in contract, or at most a three month initial period. If an agency needs twelve months of your signature to feel confident, that tells you something.
- Get month one in writing. “Ongoing optimisation” is not a deliverable. “Rewrite these six service pages, fix the internal linking, build four suburb pages” is.
- Treat any guarantee of first page rankings as a red flag. Nobody controls Google’s results, and the ACCC takes a dim view of marketing claims that cannot be substantiated.
- Insist you own the accounts. Analytics, Search Console, domain, hosting, all in your name. Getting locked out of your own data happens more than it should.
- Ask for reporting tied to enquiries and revenue, not just rankings. Position 3 for a keyword that generates nothing is not progress.
To sanity check a quote, our SEO pricing and inclusions are published openly, which makes comparison easy even if you go elsewhere.
Before signing anything, ask the agency this: “At what point would you tell me to stop?” If they cannot answer, they are selling a subscription rather than a result.
So, is SEO worth it for you?
Run the four numbers. If a client is worth $1,500 or more in gross profit over their life with you, if there are hundreds of relevant searches a month in your area, if you answer the phone, and if you can fund twelve months without flinching, then yes, and the return usually keeps arriving after year two. If two of those four are missing, put the money somewhere with a faster loop and come back when the business is ready. Not a reason to avoid SEO forever. A reason to sequence it properly.
Common questions
How long before SEO pays for itself?
Plan on twelve to eighteen months to recover the spend, with the first genuine enquiries somewhere around month five or six. Competitive Sydney categories like law, dental and plumbing sit at the long end. A regional business in a quieter niche can see movement inside three months. If someone promises payback in eight weeks, they are either selling ads under a different name or they are guessing.
Can I do SEO myself instead of paying someone?
Yes, for the basics, and plenty of owners should. Fill out your Google Business Profile properly, collect reviews consistently, write a real page for each service instead of one page listing all of them, and make sure your address and phone number match everywhere. That covers a surprising amount of local ranking. What you probably cannot do yourself is technical fixes, competitive content at volume, and link building, mostly because of time rather than difficulty.
Is SEO worth it if I already get all my work from referrals?
Often yes, but as insurance rather than growth. Referral businesses are one relationship away from a bad quarter, and referred prospects almost always search your name before ringing. Turning up well for that search closes deals you would otherwise lose quietly. Start small, maybe $600 to $900 a month excluding GST, and treat it as diversifying your lead sources rather than replacing them.
What happens if I stop paying for SEO?
Rankings do not vanish overnight. Typically you hold position for six to twelve months, then drift as competitors publish and Google reshuffles. Pages with strong links and genuinely useful content hang on longest. Thin pages that ranked on technical work alone fall first. This decay curve is the honest reason SEO beats advertising on long term economics, and it is also why stopping and restarting repeatedly wastes money.
Should I choose SEO or Google Ads if I can only afford one?
If you need work in the next 60 days, Ads. If you have twelve months of patience and a decent lifetime value per customer, SEO, because the cost per enquiry keeps falling while Ads stays flat or rises. For most service businesses under $2m turnover we suggest Ads first to prove the offer converts, then shifting budget into SEO once you know which services actually sell.
Is local SEO different from regular SEO for a small business?
Different enough to matter. Local ranking leans heavily on your Google Business Profile, review volume and recency, proximity to the searcher, and consistent business details across directories. Traditional SEO leans on content and links. A suburban tradie should put most of their effort into the local side. A national consultancy or an online retailer barely benefits from it and should focus on content and technical work instead.
