A PPC agency in London manages paid advertising campaigns — on Google Ads, Meta Ads, LinkedIn, TikTok, and programmatic platforms — for London businesses and national brands. London PPC is among the most competitive in the UK, with some of the highest cost-per-click rates across legal, financial services, and competitive B2C categories. The best London PPC agencies focus on ROAS (return on ad spend) and CPA (cost per acquisition) rather than vanity metrics like impressions and clicks.
PPC in London is genuinely expensive in competitive sectors. Financial services, legal, and insurance CPCs frequently exceed £20 per click — making inefficient campaign management catastrophically costly. The gap in ROI between excellent and mediocre PPC management is much larger in London's high-CPC market than in regional UK cities. Choosing the right PPC agency is a commercial decision with immediate and measurable consequences.
What a London PPC agency should deliver
- Rigorous keyword research and negative keyword management to eliminate wasted spend
- Conversion tracking setup that accurately attributes leads and sales to specific campaigns
- Audience segmentation and targeting that goes beyond broad demographic targeting
- Ad copy that competes effectively in high-CPC London markets
- Landing page optimisation recommendations to improve conversion rate
- Monthly reporting focused on CPA, ROAS, and revenue — not impressions and CTR alone
- Google Shopping management for London retail businesses
London PPC agency management fees typically range from 15–20% of ad spend (with a minimum monthly fee of £750–£1,500) or a flat monthly retainer of £1,000–£5,000+ for larger accounts. Total investment (agency fee plus ad spend) for a meaningful London PPC programme starts from £3,000 to £5,000/month. In high-CPC sectors (legal, finance, insurance), ad spend alone may need to be £10,000+/month to generate sufficient volume for optimisation.
Request case studies showing specific CPA or ROAS improvements with comparable client sizes and sectors. Ask who sets up and manages your account day-to-day — not the senior strategist who sells the account. Confirm that your ad account is held in your name (not the agency's). Ask about their approach to conversion tracking, negative keywords, and audience exclusions — these unglamorous details determine whether ad spend is efficient or wasted.
