Which Strategy Fits Your Situation?
New business — no website traffic
Start with Google Ads + build SEO foundation
Use Ads to test immediate demand while the SEO foundation is built. Reduce ad spend only after tracked organic enquiries are consistently replacing paid leads—not according to a preset month.
Timeline: Ads can launch first; assess SEO over a longer measurement window.
Est. cost: Example only: chosen ad budget + Local SEO plan.
Established business — steady customers
SEO focus, light Ads for competitive terms
You already have word-of-mouth and repeat customers. Invest in SEO to capture people searching for your services. Use Ads only for high-value emergency keywords (e.g., 'emergency plumber Adelaide') where organic ranking takes longer.
Timeline: Review organic movement monthly; use Ads where immediate visibility is valuable.
Est. cost: Local SEO plan + a campaign budget based on lead economics.
Competitive market — lots of competitors
Both, with heavy SEO investment
Run Ads for controlled visibility while investing consistently in technical work, useful content, proof and authority. Reduce spend only when lead-source data shows organic search can carry more of the target.
Timeline: Expect a longer SEO measurement window in competitive categories.
Est. cost: Growth SEO plan + an evidence-based ad budget.
Niche market — few competitors
Test SEO first; keep Ads available
A niche such as ‘fencing contractor Modbury’ may have a clearer organic opportunity, but low competition does not guarantee ranking or lead volume. Start with the foundation, measure demand, and add Ads if the business needs faster validation.
Timeline: Set a baseline, then review indexing, impressions, enquiries and competition.
Est. cost: Local SEO plan; optional test budget for Ads.
24-Month Cost Projection
The table below is an illustrative budget scenario, not a forecast. Reduce ad spend only if measured organic leads and won revenue support the decision.
| When | SEO Cost | Ads Cost | Combined |
|---|---|---|---|
| Month 1 | $399/mo | $1,000 | $1,399 |
| Month 3 | $399/mo | $1,000 | $1,399 |
| Month 6 | $399/mo | $800 | $1,199 |
| Month 12 | $399/mo | $500 | $899 |
| Month 18 | $399/mo | $300 | $699 |
| Month 24 | $399/mo | $200 | $599 |
Key insight: By month 24, your SEO is generating organic traffic that replaces most of your ad spend. These figures demonstrate how a budget could change; they are not a quote, forecast or recommended spend. Build the real model from your click costs, conversion rate, qualified leads and won revenue.

FAQs
Should I do SEO or Google Ads first?
If you need immediate visibility, Google Ads can begin once the campaign is approved and launched. SEO usually needs a longer measurement window. Using both can make sense, but the split should be based on margins, urgency, search demand and tracked lead quality.
How much should I spend on Google Ads in Adelaide?
Work backwards from the value of a qualified lead, your close rate, target job volume and current auction estimates. A useful test budget must buy enough relevant clicks to learn something, but there is no responsible universal Adelaide spend figure.
How long does SEO take to work in Adelaide?
There is no fixed timeline. Competition, starting authority, technical condition, content quality, location and Google's systems all matter. Specific service-and-suburb searches can present a more focused opportunity than broad Adelaide terms, but they are not automatically easy.
Is SEO cheaper than Google Ads?
It can be, but only your lead and revenue data can answer that. SEO can continue producing organic visits without a per-click media fee, while Ads provide faster control over placement and budget. Compare cost per qualified lead and won revenue over a long enough period.
Can I just do Google Ads and skip SEO?
You can rely on Ads, but paid placement stops when the campaign or budget stops. Organic visibility is not permanently owned either—rankings can change. A balanced acquisition mix reduces dependence on one channel and gives you better data about what produces qualified work.
