What is SEO? A plain-English guide for Australian business owners
Search engine optimisation explained without jargon: how Google ranks pages, what SEO work involves and how to tell if it’s working.
The simple version
When someone searches for “electrician in Ringwood”, Google tries to show the most useful, trustworthy result. SEO is everything you do to make that result your website.
The three parts of SEO
Technical: Google needs to crawl, render and understand your pages. Speed, mobile layout, site structure and structured data all live here.
Content: each page should fully answer the search it targets. A page about hot water repairs should explain the problem, the options, rough costs and how to book.
Authority: links and mentions from other reputable sites, plus reviews and brand searches, signal that people trust you.
How SEO differs from ads
Ads stop when you stop paying. SEO keeps working once you rank, which is why it often becomes the cheapest source of leads over time.
How to tell if it’s working
Rankings are a means, not the goal. Track organic traffic to your service pages, calls and forms from organic visitors, and the share of enquiries that come from search.
And now AI
Google’s AI Overviews and assistants like ChatGPT draw on the same foundations. Good SEO is the base for being cited in AI answers too.
