AU First-Home-Buyer CTR Compression at SERP Positions 4-15: A May 2026 Baseline

This is a first-party empirical baseline for the click-compression pattern that has accompanied the rollout of AI Overviews in Australian search. AI Overviews now appear on a large share of Australian informational queries, and Google AI Mode was announced as a default search experience at Google I/O 2026 (19 May). The numbers below document one finance vertical's experience over the 28 days that followed.

Headline finding

Across 18 nestpath.com.au pages ranking SERP positions 4-15 in Australia over the last 28 days ( to ), Google Search Console recorded 8,325 impressions and only 48 clicks (0.58% CTR). At the industry-benchmark CTR curve for those positions the expected click count would have been 175, a shortfall of 72.6%.

Site totals, prior period comparison

Across the entire nestpath.com.au property over the 28-day window, Google Search Console recorded:

MetricCurrent 28 daysPrior 28 daysChange
Clicks135101+33.7%
Impressions42,06132,416+29.8%
CTR0.32%0.31%+0.01pp
Average position40.734.2+6.5

Impressions and clicks both grew about 30%, but CTR stayed essentially flat at 0.32% while the average SERP position slipped by 6.5 places. The site is being shown to more searchers; the extra impressions are converting at the same near-zero rate.

The position 4-15 zero-click cohort

To isolate the AI-Overview effect from generic low-ranking noise, the dataset filters to pages ranking SERP positions 4-15, where industry-benchmark CTR ranges from roughly 1.5% to 8% under classical "10 blue links" SERP behaviour. Below this band the absence of clicks is unremarkable; above it (positions 1-3) the click-through curve is dominated by brand and intent factors specific to the query.

18 pages cleared the position 4-15 filter and had at least 100 impressions over the window. They are listed below, sorted by SERP position.

The aggregate 0.58% CTR against the 2.10% benchmark represents a 72.6% shortfall. One page, /homeowner-hub/best-iron-australia, accounts for 45 of the 48 clicks. The other 17 pages combined attracted just 3 clicks across 4,447 impressions: an actual CTR of 0.07% against an expected about 100 clicks.

Methodology

  • Source. Google Search Console API for the verified nestpath.com.au domain property. Non-bot sessions only.
  • Window. Rolling 28-day period to .
  • Filter. Pages ranking SERP positions 4-15 (one decimal place, average over window) with at least 100 impressions in the window. Position 1-3 and position 16+ excluded as out-of-scope for this analysis.
  • Benchmark CTR curve. Composite of Sistrix 2024, Advanced Web Ranking 2024, and Backlinko 2023 organic-CTR-by-position studies. Values smoothed across position bands. Curve: pos 4 = 8.0%, pos 5-6 = 5.1%, pos 7-9 = 3.2%, pos 10-12 about 2.0%, pos 13-15 about 1.5%.
  • Expected clicks. impressions times benchmark CTR for each page's average position. Shortfall = 1 minus (actual clicks / expected clicks).
  • Reproducibility. Any operator with GSC access to the property can run the query: dimension=page, filter by avg_position 4-15, min_impressions at least 100, 28-day window. Raw output is in /data/au-fhb-ctr-collapse-2026-05.json.

What this dataset does not claim

The data above documents a CTR shortfall against historic position benchmarks. It does not, by itself, prove the shortfall is caused by AI Overviews: alternative explanations include title/meta-description weakness, brand recognition, SERP-feature competition from People-Also-Ask boxes, knowledge panels, and competitor snippet dominance. Disentangling cause is beyond the scope of a single-property baseline.

What the data does establish, narrowly:

  • For nestpath.com.au, ranking at positions 4-15 is currently a near-zero-click outcome in the Australian SERP environment.
  • The shortfall is consistent across 18 different pages spanning 7 distinct content categories (FHB schemes, home loans, conveyancing, stamp duty, hub product comparisons, regional buying guides). The pattern is not concentrated in one URL or topic.
  • Impression growth (+30%) without CTR growth (+0.01pp) indicates Google is showing these pages to more searchers, but not converting that exposure to clicks.

Implication for editorial strategy

If ranking at positions 4-15 no longer produces clicks at historic rates, then for this site ranking on its own is no longer a good measure of SEO success. Whether AI engines cite the source in their answers may matter more, and that is measurable separately via referrer logs (see /cited-by-ai for our monthly snapshot of AI-attributed traffic to NestPath).

Two practical inferences for editorial teams operating in similar verticals:

  • Position 1-3 still matters disproportionately because that is where AI Overview citations typically pull from. Investments that move position 8 to position 3 now likely carry more value than the same investment moving position 50 to position 8.
  • Structured-data quality and citability seem to matter more at the top of the SERP. The same content with clearer entity markup, stronger first-party data and a tighter answer-first lead paragraph gets pulled into AI answers more often. The NestPath methodology page documents how we apply this.

Refresh schedule

This baseline refreshes on the same 28-day cycle as /cited-by-ai. Future cycles will be archived at dated URLs (planned: /research/au-fhb-ctr-collapse-2026-NN) so the trend is auditable. Per the NestPath dateModified honesty rule the timestamp advances only on a real data refresh, never as a cosmetic bump.
