Behavioural Search: Google's Strategic Pivot in 2025
Google’s March 2025 core update marks a strategic pivot towards behavioural search. This means the algorithm is no longer just parsing keywords or backlinks. It is interpreting user intent, engagement patterns and trust signals at scale. According to Google Search Liaison Danny Sullivan, the update enhances how the system evaluates “content that aligns with user expectations and demonstrates experience.” This is consistent with the broader trend towards E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), which is now embedded in Google’s ranking architecture. In Australia, this shift has been particularly visible in sectors like health, finance and government services. Pages that previously ranked due to domain authority or backlink profiles have dropped, while those with clear, structured, user-aligned content have surged. This means traditional SEO tactics, like keyword stuffing or thin content, are now penalised. Instead, Google is rewarding: - Structured data that clarifies content purpose - Author-level signals that demonstrate expertise - Behavioural alignment with user queries and follow-up actions
Algorithm Volatility: Winners, Losers and What Changed
The March 2025 core update has produced the most volatile SERP (Search Engine Results Page) shifts since the 2022 Product Reviews update. Tools like Semrush Sensor and RankRanger reported volatility scores above 9.2 across Australian verticals.
Key sectors affected include:
- News media: Sites like The Guardian Australia saw sharp drops in non-branded traffic due to over-optimised archive pages.
- E-commerce: Platforms such as Catch.com.au experienced gains due to improved product schema and user reviews.
- Government and services: Pages with outdated or inaccessible information were demoted, while those using structured markup and plain English content improved.
The update also appears to favour localised content. Businesses that have invested in location-specific schema, Google Business Profiles and mobile-first design have seen improved rankings.
In short, volatility is not random. It is the by-product of Google’s deeper understanding of user trust and intent.
SEO Adaptation: How Australian Sites Must Respond
To adapt to the March 2025 update, Australian organisations must shift from tactical SEO to strategic content architecture. This requires integrating behavioural science, structured data and entity-level optimisation.
Key adaptation strategies include:
- Entity SEO: Optimise for people, places and organisations using schema.org and Wikidata references.
- Content integrity: Ensure every page has a clear purpose, author attribution and updated information.
- Trust signals: Use HTTPS, transparent privacy policies and accessible UX to build trust.
- Behavioural framing: Align content with user journeys, not just queries. Anticipate next steps and reduce cognitive friction.
Consultancies like Bushnote, which combine behavioural insight with technical SEO, are increasingly being favoured by government and institutional clients. Their ability to translate policy, science or brand strategy into search-optimised content is a key differentiator in this new landscape.
Integrated Strategy: Aligning Content, Context and Credibility
The 2025 algorithm update is not just a technical event. It is a strategic signal. Google is telling us that content must be credible, contextual and behaviourally aligned.
This means SEO is no longer a silo. It must be integrated with:
- Policy communication: For government and public sector sites
- Brand strategy: For companies seeking authority and trust
- Behavioural design: For organisations aiming to influence decisions
For example, CSIRO’s recent digital overhaul included structured data, plain language and author bios, leading to improved visibility across health and climate topics. Similarly, Canva’s educational content now ranks higher due to its intent-driven structure and interactive UX.
In short, the March 2025 update is a forcing function. It demands that content creators, strategists and developers work together. The future of SEO in Australia is integrated, intelligent and intent-led.
TLDR: The March 2025 Google algorithm update in Australia has introduced significant volatility, rewarding content that demonstrates trust, relevance and behavioural alignment. Businesses must shift from keyword-first strategies to entity-based, intent-driven SEO. Structured data, E-E-A-T signals and content integrity are now essential to maintain or grow rankings.
