Has It Actually Worked?
The short answer is yes, and we can see that growth in both AI visibility and traditional search performance.
When we began tracking Ideal Heating through LLMLens in May 2026, the brand held an 11.5% AI share of voice, with 2,737 mentions. By September, that had increased to 11.9% and 6,421 mentions, with Ideal’s trajectory beginning to close the gap on Baxi in mention volume. Our tracking had expanded too, from 1,050 to 1,634 prompts across eight LLMs, giving us a much broader view of where and how the brand was appearing.
And there were some particularly strong signals within that wider growth. On GPT-5.1, Ideal reached 6.57 mentions per prompt, the highest citation rate of any brand on any model within our dataset. In other words, we’re not just seeing Ideal mentioned more often, we’re also seeing areas where the brand is becoming a particularly strong source within AI-generated answers.
But remember that bit about not optimising for AI in isolation? This is where the Google results become particularly interesting.
The content strategy informed by that wider analysis hasn’t been about creating individual pages for individual prompts. We’ve been strengthening existing content, filling genuine gaps and building out wider topic clusters, including the combi boiler cluster we touched on earlier.
Since July, 30 pieces of optimised content have gone live, with the combi boiler content becoming one of the biggest ranking drivers. Across the combi keyword set, average ranking position improved by around six places in four weeks, while the number of keywords sitting in positions 1–3 increased 12.5% month on month.
And some of those movements are substantial. “Which combi boiler” moved from position 15 to 2, while “which combi boiler is best” moved from 100 to 12. The Boiler Costs guide also reached page one for four high-intent cost terms representing a combined 7.2K searches per month.
We’re seeing that improvement translate further down the journey, too. In August, organic sessions increased 10.3% month on month, while organic conversions increased 20.3% to 15,733.
That’s why we’re not looking at the LLMLens numbers in isolation. The AI visibility is improving, but so is the wider search performance of the content and topic areas we’re investing in. Growing Ideal’s presence in AI hasn’t meant choosing AI over Google; we’re using the additional intelligence to make better decisions across both.
