The final speaker in this session at the AANZCA 2025 conference is Merja Myllylahti, whose interest is in changes to how ongoing changes to search engines well beyond AI are changing Web traffic to news outlets. This takes a broader view of audience behaviours in relation to search, and of structural conditions in the search marketplace.

There have been significant concerns about a decline in traffic to news sites; however, the evidence for this decline remains limited at present. Comparing 2018 and 2025 traffic patterns for New Zealand, for instance, traffic from search seems fairly stable; it is the traffic …

My QUT colleague Kateryna Kasianenko is the next speaker in this session at the AANZCA 2025 conference, focussing on how search engines respond to searches about conspiracy theories. Search engines are a common pathway towards conspiracist information; they have the potential to affect their users’ understanding of such information. What people see when they search for such content also depends directly on how the query itself is formulated, so query variations also need to be studied systematically. Our Australian Search Experience 2.0 project within the ARC Centre of Excellence for Automated Decision-Making and Society explores the impact of such query …

The final session on this first day of the AANZCA 2025 conference starts with my QUT colleague Shir Weinbrand, whose focus is on the emergence of AI Overviews in Google Search. These are a relatively new addition which fundamentally changes how search engines work: they provide an AI-generated synthesis of search results rather than pointing users to the search results themselves.

How are these changes being framed; how are different actors describing these changes – Google itself, technology journalists, and SEO marketers? This study engaged in computational concept mapping of the discourses around AI Overviews between May 2024 and May …

After the great excitement of AoIR 2025 in Rio de Janeiro, I’m now at my final stop on this conference trip, at the ZeMKI 20th anniversary conference in Bremen which promises to be an equally stimulating event. The theme here is “20 years into the future”, and we start with a keynote by the great José van Dijck. Her focus is on digital sovereignty in Europe under the current and emerging global circumstances.

This responds to the platformisation of public communication in society; public participation via platforms is possible only after signing up to one or more (US-headquartered) platforms, for …

And the final speaker at the SEASON 2025 conference, very fittingly, is our host Dirk Lewandowski, presenting findings from a study commissioned by the German State Media Authorities that focussed on the transformation of online search by the introduction of artificial intelligence technologies. This is of course still in progress, so no definitive results should be expected yet. The study was conducted in May 2025, and results will be published in mid-October.

But we can already reflect on whether the introduction of AI represents a revolutionary transformation, or merely an incremental change; and on how AI-enhanced search affects the economic …

My own paper starts the final session at the the SEASON 2025 conference, presenting the Australian Search Experience team’s work towards assessing the effect of search query formulation on the diversity of search results, within the ARC Centre of Excellence for Automated Decision-Making and Society. Here are the slides: 

The final speaker in this session at the SEASON 2025 conference is Elsa Lichtenegger, whose projects is exploring the question of search intent. Why do people search, what drives them, what is their motivation, what are their goals? Search intent describes the user’s underlying goal or purposes, which is expressed through the initial search query and may be refined through further search iterations.

A definition of search intent by Broder (2002) tends to be dominant in the available literature on the topic; this has considerable impact on extant research. It distinguishes three types of user intent: informational intent (seeking information) …

The next speaker in this session at the SEASON 2025 conference is Desheng Hu, whose project is auditing Google’s AI Overviews and Featured Snippets, especially in the context of information seeking on pregnancy and childbirth. Many new parents will be using Google for information-seeking as well, and may blindly trust the information they obtain; this information now also includes the recently introduced AI Overviews and/or Featured Snippets.

These are often placed at the very top of the page, and will thereby capture a great deal of users’ attention – but they have already been shown to be unreliable and inconsistent …
