In this conversation, James Dooley and Kasra Dash break down the most effective digital marketing strategies for London-based businesses in 2026 — with one rule above everything else: track ROI properly. Kasra explains how to build a KPI framework that measures spend, lead volume, contact rate, and actual revenue per channel so business owners can confidently switch off underperforming campaigns and double down on what’s working. James shares why brand SEO and reputation (your brand SERP) should be the foundation before scaling any channel, and why AI visibility across ChatGPT, Claude, Gemini, Grok, Perplexity, and Google AI Overviews is becoming a major factor for conversions and trust. They also cover performance-based lead generation, Google Business Profiles (local SEO), organic SEO, organic + paid social, PPC best practices, early opportunities in AI advertising, forum-driven word-of-mouth (Reddit/Quora), and tradesman/lead platforms — all through the lens of predictable tracking and avoiding a single point of failure.
