Sign-ups up 18% — organic search driving the gains
Trial registrations hit 147 in the past 28 days, with Google Organic accounting for most of the lift. Paid conversion rates remain flat.
What matters
01
Organic search driving sign-up growth
Google Organic sessions grew 31% period-over-period and now contribute 38% of all trial sign-ups.
Why If the SEO lift is tied to a specific content cluster, doubling down there is likely your highest-ROI acquisition lever this month.
Impact Organic converts at 1.76% vs 1.2% for paid — a meaningful gap worth protecting.
02
AI referral traffic appeared for the first time
47 sessions arrived via ChatGPT and Perplexity — a channel that was near zero last period.
Why AI assistants are starting to recommend your product. Those landing pages should be optimised for the high-intent visitors they send.
Impact AI-referred visitors showed a 2.1% sign-up rate — above site average.
03
Mobile conversion rate significantly below desktop
Mobile users convert at 0.9% vs desktop at 2.3% — a gap that's widening as mobile share grows.
Why Mobile is now 35% of sessions. Closing even half the conversion gap would add ~20 sign-ups per period at current traffic.
Impact Closing the mobile gap to 1.5% would add ~18 sign-ups per period.

Review /pricing and /features for mobile UX — these are your AI-referral landing pages
Why AI referrals are landing on these pages and converting above average, but mobile experience is dragging overall performance.
Signal Mobile sign-up rate moves above 1.5% on these two pages.
Quick win
Create a custom channel group in GA4 to track AI referral sources consistently
Why ChatGPT and Perplexity sessions currently land in (direct) or referral without consistent attribution — proper grouping lets you track ROI as this channel grows.
Signal AI referral sessions visible as a distinct channel group in GA4 reports.
Paid social cost-per-click rising
LinkedIn Ads sessions dropped 22% while spend held flat — CPCs are rising without a conversion rate improvement to offset it.
