What Google actually does
Google runs software that fetches pages (crawling), works out what they are and what they say (rendering and indexing), and then, when someone searches, picks the pages it thinks will satisfy that person (ranking). Since 2025 it also writes answers of its own, in AI Overviews and AI Mode, drawing on the same index. Everything in SEO is about being easy to fetch, easy to understand, and the best available answer for a specific question.
The three things that decide where you rank
Content
Does the page answer the question the searcher had, better than the alternatives? Google’s own guidance calls this helpful, people-first content: written for a person, by someone with first-hand expertise, with a clear author and a clear purpose. Pages written to rank rather than to help are now named in Google’s spam policies, including pages generated at scale and pages that swap a suburb name into the same text.
Links
Other sites linking to yours still matter, because a link is a vote from someone who did not have to give it. What changed is that bought links, link networks and link exchanges stopped working and started hurting. The links that count come from relevant sites with real audiences: suppliers, partners, industry bodies, local press, and pages good enough that people cite them.
Technical quality
Can Google fetch every page it should and none it should not? Does the page load fast on a mid-range phone on a mobile network? Does the layout stay still while it loads? Is the structure marked up so that a machine can tell a price from a phone number? Core Web Vitals, structured data, canonical tags, redirects and sitemaps all live here. None of it is visible to a customer, and all of it caps what the content can achieve.
Local search is its own game
For a search with local intent, Google shows a map with three businesses before any website. Those three are chosen from Google Business Profiles, on relevance, distance and prominence. Your website supports that listing but does not replace it. A Sydney plumber with a perfect website and an unclaimed profile is invisible to most of their customers.
What AI search changes, and what it does not
Google says there are no extra requirements to appear in AI Overviews or AI Mode. The AI answers are assembled from pages that rank well, answer specific questions directly, load quickly and carry accurate structured data. The practical change is that a page should answer the sub-questions a buyer has (what does it cost, how long does it take, who is it for) rather than only the headline query, because AI Mode breaks a question into those parts and looks for each.
What stopped being true
- Meta keywords do anything. They have been ignored since 2009.
- Keyword density, LSI keywords and word-count minimums. Google measures whether the page is useful, not how often a phrase appears.
- Title tags must be under 49 characters. Aim for clarity in about 50 to 60 characters; Google rewrites long ones.
- One H1 per page is a rule. It is a convention worth keeping for readers, not a ranking factor.
- Penguin, Panda and the rest are things to recover from. They are part of the core algorithm and have been for a decade.
- Social signals are a ranking factor. They are not, though social can earn links and attention.
What this means for a Sydney business
Fix the technical problems first, because they cap everything else. Claim and run your Business Profile properly. Write one good page for each thing you do and each area you serve, with your real expertise in it. Earn a handful of links from sites that matter in your industry and your area. Measure enquiries, not rankings. Then keep doing it, because a site that is left alone drifts backwards.
That is the whole job. The audit tells you where your site stands on each part.
