What Is Digital Marketing? A Practical Guide for Australian Small Business
Six channels, wildly different jobs, and most small businesses run all of them badly instead of two of them well. Here is what each channel is genuinely good at, what it costs to run properly in Australia, and how to pick.
Digital marketing is every way you reach customers through a screen: search (SEO and Google Ads), social media both organic and paid, email and SMS, content, reviews and reputation, and referral or partnership work. Most Australian small businesses should run two of those properly rather than six badly, and budget $1,500 to $4,000 a month excluding GST before any of them produces real enquiries.
What actually counts as digital marketing?
Six channels, give or take, doing genuinely different jobs. Search captures demand that already exists. Social creates demand that does not. Email and SMS sell again to people who already trust you. Content feeds search and answers objections before anyone rings. Reviews decide whether the person who found you bothers to call. Referral work is the cheapest lead source most businesses own. The mistake is reading that as a checklist. It is a menu, and you are ordering for one.
What is each channel genuinely good at, and what does it cost?
Each channel has one job it does better than everything else, and a longer list of jobs it does badly. Pick on the job, not on what is fashionable. Prices below are monthly, Australian dollars, excluding GST, and reflect running a channel properly rather than the cheapest possible version.
| Channel | Best for | Realistic monthly cost | Time to results |
|---|---|---|---|
| Google Ads (search) | Urgent, high intent services where demand already exists | $1,500 to $5,000 ad spend plus $600 to $1,500 management | 1 to 4 weeks |
| SEO | Compounding enquiries you keep after you stop paying | $1,000 to $3,000 | 4 to 9 months |
| Google Business Profile and reviews | Local map pack visibility and trust before the call | $0 to $300 | 4 to 12 weeks |
| Paid social (Meta, Instagram) | Creating demand, visual work, retargeting site visitors | $800 to $3,000 ad spend plus management | 2 to 8 weeks |
| Organic social | Staying in the memory of people who already know you | 4 to 8 hours of your time, or $500 to $1,200 outsourced | 6 to 12 months |
| Email and SMS | Selling again to past clients and warm enquiries | $50 to $400 in tooling plus writing time | Same week, on the first send |
| Content and guides | Feeding SEO and answering sales objections at scale | $600 to $2,000 | 3 to 9 months |
| Referral and partnerships | Highest close rate of anything, near zero cash cost | Almost nothing in dollars, real time in hours | Weeks to months |
Search: SEO and Google Ads
Search is where people go once they have decided they need something. Somebody typing emergency electrician Parramatta at 7am is not browsing. That intent is why search is the first channel we recommend for most service businesses, and why it is an expensive place to be careless.
Google Ads buys the top of that page today. Live by Thursday, control over suburbs and hours, off again when the diary fills. You never stop paying, and clicks in legal, finance and the trades routinely run $12 to $45 each in Australian metro markets. That is why a properly managed Google Ads campaign matters more than the size of the budget. A badly built account burns $2,000 on broad match rubbish before you notice.
SEO buys the same position slowly and then keeps it. Four to nine months on a competitive term, and it does not go dark the month you skip an invoice. Neither is better. They answer different questions about your cash and your patience, covered further across our Google Ads and marketing guides.
Social: organic and paid
Organic social is a memory device, not a lead source. Post consistently and people who already know you keep remembering you exist, which is worth something, particularly for trades posting before and after shots. Not a pipeline, though. We have clients with 4,000 followers and two enquiries a year to show for it, and we have told them so.
Paid social is different work. Meta ads create demand where none existed and retarget people who visited your site and left, which is nearly all of them. Allow $800 to $3,000 a month before the data is worth reading. Weak for urgent services: nobody scrolling Instagram at 9pm decides their hot water system has failed.
Email and SMS
Email is the highest return channel almost nobody uses properly. Fifty to four hundred dollars a month in tooling, sent to people who already bought from you. A quarterly email to 600 past clients reliably shakes loose work. Writing it is a two hour job. Most businesses have not sent one in three years, then wonder why repeat work dried up.
SMS gets read inside a few minutes, so ration it: appointment reminders, booking confirmations, the occasional genuinely time limited offer. Both sit under the Spam Act 2003, covered below, and that part is not optional.
Content
Content is not blogging for the sake of having a blog. It is writing down the answers you already give on the phone six times a week, once, properly, so search engines and AI assistants can find them. A page that honestly answers what this costs does two jobs: it ranks, and it filters out people who were never going to pay your rate. Slow on its own. Budget $600 to $2,000 a month outsourced, and expect three to nine months before it earns back.
Reviews and reputation
Reviews are the cheapest conversion lift available and cost close to nothing. Your Google Business Profile rating is the last thing somebody checks before ringing. Moving from 4.1 stars with 11 reviews to 4.7 stars with 60 brings no extra traffic; it changes how many of the people who already found you make contact.
Ask every satisfied client by text, with a direct link, within 48 hours of the job. Never buy reviews or offer anything of value in exchange for a positive one. The ACCC treats fake and incentivised reviews as misleading conduct and has taken businesses to court over it.
Referral and partnerships
Referral work closes at rates no advertising channel gets near. An accountant who sends you three clients a year is worth more than a $2,000 monthly ad budget, and the cost is a few coffees plus the discipline to send work back. It gets ignored because it cannot be scheduled or reported on neatly. Do it anyway. Pick four businesses that serve your customer just before you do.
Why do most small businesses end up spread across six channels?
Because every channel sounds mandatory when somebody is selling it to you. The result is a pattern we see constantly: a half maintained Facebook page, a blog with four posts from 2022, a Google Ads account nobody has opened since setup, an email list that has never been emailed, and an owner who has decided digital marketing does not work in their industry.
None of it worked because none of it got past the point where it starts working. A channel run at 30 per cent effort does not return 30 per cent of the result. It usually returns nothing, because rankings, ad algorithms and audience habits reward consistency and punish stop start.
Rule of thumb: give a channel three months and a budget you would defend out loud before you judge it. Anything shorter and you are measuring noise, then making a permanent decision off it.
Which two or three channels should you pick?
Pick on how urgent your customer’s problem is and how much runway you have. Here is what we would actually say, by business type.
- Emergency and urgent trades (plumbing, electrical, locksmiths): Google Ads plus Google Business Profile and reviews. Nothing else until both are humming.
- Professional services and consultants (accounting, legal, financial advice): SEO plus content, referrals third. Long buying cycles reward the compounding channels.
- Healthcare and allied health: reviews and Google Business Profile plus local SEO, then email for recalls.
- Product and online retail: paid social plus email. Search later, once you know which products convert.
- Brand new, no reputation, no traffic: Google Ads to buy market data quickly, reviews from the first job.
Add a third only once the first two run without you thinking about them weekly. And if you already spend on ads but cannot tell me your cost per enquiry off the top of your head, Instagram will not fix that. Handing the account to someone who watches it daily might.
What should you actually measure?
Three numbers, and impressions is not one of them. Cost per enquiry, enquiry to client conversion rate, and average client value. Know those and you can decide whether a channel deserves funding. Know only that traffic rose 22 per cent and you know nothing useful.
Last click attribution is the main reason good channels get cut. Analytics hands credit to whichever source touched the visitor last, almost always branded search or direct traffic. The customer who saw your Facebook ad in March, read two of your guides in April, then googled your business name in May gets logged as a free organic win. The ad and the content look like wasted money. They were the reason the sale happened.
The fix is not a cleverer attribution model. Ask every enquiry how they heard about you, record it in your CRM, and compare that against analytics each quarter. Crude and self reported, but more honest than any attribution setting. Track phone calls too, because service businesses lose most of their attribution when the leads ring instead of filling in a form.
What does the Spam Act 2003 require for email and SMS marketing?
Three things, on every commercial email or SMS an Australian business sends: consent, clear identification of the sender, and a working unsubscribe. The Australian Communications and Media Authority enforces it, and penalties run into six figures for repeat offenders. Not a paperwork formality.
Consent is either express (they ticked a box, filled in your form, handed over an address for this purpose) or inferred (an existing business relationship, and the message is clearly relevant to it). A client you did work for last year is generally fine. A list you bought, scraped off a directory, or collected in a fishbowl at an expo with no signage is not. Pre ticked boxes are not express consent.
Identification means the message plainly states who sent it and how to reach you. Business name and current contact details in the footer covers it.
Unsubscribe means a functional opt out in every commercial message, honoured within five working days, free to use, still working at least 30 days after the send. No logging in, no ringing the office to get off the list. Keep records of when and how each person consented, because if ACMA asks, the burden of proof sits with you.
The Spam Act applies to marketing texts sent from your own mobile, not just from a platform. A bulk offer sent to 200 old customers from the phone in your pocket carries the same obligations as an email blast. None of this is legal advice; if you run large lists, have it checked.
So where should you start this month?
Fix the reviews and the Google Business Profile first, because it is free and it lifts everything else. Then pick one paid channel and one owned channel, fund both for a quarter, and measure cost per enquiry honestly. Nothing else gets added until those two are boring and predictable.
Common questions
How much should a small business spend on digital marketing overall?
A common working range for Australian service businesses is 5 to 10 per cent of revenue, excluding GST, weighted toward the higher end if you are growing or entering a new area. On $600,000 of revenue that is roughly $2,500 to $5,000 a month across everything, including ad spend and management. Below about $1,500 a month total, pick one channel and one only, because splitting it further guarantees nothing gets past the threshold where it works.
Can I run all of this myself instead of paying an agency?
Reviews, email to past clients, organic social and referral partnerships are all realistically DIY, and you will do them better than an agency because you know the clients. Google Ads and technical SEO are where self managing gets expensive quietly, since the money leaks in ways the dashboard makes look normal. A fair split is doing the owned channels yourself and paying someone for the paid ones.
Is LinkedIn worth the effort for an Australian small business?
It depends entirely on who signs your invoices. If you sell to other businesses, especially professional services, finance or anything with a long sales cycle, LinkedIn is the one organic social channel with a real shot at producing enquiries. If you sell to homeowners, it is a waste of your Tuesday. A tiler does not need LinkedIn. A commercial fit-out consultant probably does.
How long should I give a new channel before pulling the plug?
One full quarter for paid channels, six to nine months for SEO and content. Paid social and Google Ads need roughly 30 to 50 conversions before the data means anything, which at a $200 cost per enquiry is $6,000 to $10,000 of spend. Killing a channel at week three is not a decision, it is a guess. Killing one after a properly funded quarter with clean tracking is a decision.
Do I still need a website if my Facebook page is busy?
Yes, for two reasons. You do not own the Facebook page, and a policy change or a hacked account can remove your entire presence overnight with no appeal worth the name. Second, search traffic and Google Ads both need somewhere to land that you control. A social page is a good shopfront window. It is a terrible foundation to build a business on.
What is the most common digital marketing mistake you see?
Spending on traffic while ignoring what happens when it arrives. Businesses will happily commit $2,000 a month to ads pointed at a site with a slow load time, no phone number above the fold and a contact form nobody has tested since 2021. Doubling your enquiry rate costs a fraction of doubling your traffic. Fix the destination before you buy more visitors to send there.
Does organic social ever beat paid advertising for lead generation?
Occasionally, and almost always in visual trades where the work photographs well: landscaping, renovations, cabinetry, hair and beauty. If your finished job is genuinely impressive to look at and you post it consistently for a year or more, organic can produce steady enquiries. For everything else, treat it as reputation support rather than a lead source, and do not let it eat the hours your paid channels need.
