The Peak Digital UK PPC Index for September 2026

The Peak Digital UK PPC Index closes June 2026 with head-term cost per click higher month on month in 12 of its 19 verticals and tail-term cost per click higher in 9. The index median sits at £4.08 on head terms and £5.07 on tail, with head CPC spanning £1.62 in estate agents to £17.21 in solicitors and tail CPC spanning £1.83 in wedding venues to £21.27 in B2B SaaS. Tail CPC exceeds head CPC in 11 of the 19 verticals, the same 11 as in May. Sample sizes recovered to between 23 and 25 keywords per vertical, against the 13 to 21 recorded in January 2026.

Six verticals recorded a 24-month head-term high in June: accountants, electricians, lettings agents, mortgage brokers, private dentists and private GP. Four recorded a 24-month tail-term high: B2B SaaS, lettings agents, mortgage brokers and private GP. The largest movements sit with mortgage brokers, where head CPC rose 38.2 per cent month on month, and lettings agents, where both series now sit around 50 per cent above their prior 12-month averages. B2B SaaS is the clearest divergence in the panel, with head CPC 12.1 per cent below its prior 12-month average while tail CPC sits 29.7 per cent above its own.
