Three months of optimisation moved the account from volatile to predictable. Total conversions rose 52%, conversion value rose 98% and return on ad spend rose 323%.
The gap between the conversion figure and the value figure is where the work shows. Conversions grew by half while the value of those conversions nearly doubled, so each conversion was worth around 30% more than before, which means the account stopped buying applications and started buying loans it could fund. The return figure says the rest: a 323% rise in return on ad spend against a 98% rise in value implies the account produced that value on roughly half the spend, with cost per acquisition falling by roughly two thirds, assessed against funding outcomes rather than submission counts. Week-over-week performance became consistent enough to scale from, which for a lender is the difference between a channel and an experiment.
The scaling in visibility is independently recorded. Semrush’s UK index shows the account moving from a narrow, cautious position of 13 tracked paid keywords to a peak of 163, and settling since at roughly ten to fifteen times its starting visibility.

Semrush UK index, paid keywords and estimated paid traffic by month: November 2025 13 / 581; December 38 / 3,775; January 2026 86 / 4,998; February 163 / 12,528; March 136 / 13,510; April 58 / 5,496; May 62 / 6,607; June 99 / 6,437; July 124 / 8,831. Semrush estimates are modelled from the ads it observes in search results and cannot see spend or actual clicks, so the traffic column is a visibility index rather than a visit count.
