For brands in London that need a Digital Marketing Strategist who can plan, build and optimise end-to-end campaigns, Alex Costin offers a rare full-stack alternative to traditional agencies. With 17+ years of hands-on experience across SEO, PPC, content, social, web development and analytics, Alex helps businesses halve marketing costs while doubling ROI through data-driven strategy and flawless execution.
Why hire a Digital Marketing Strategist in London?
London’s digital landscape is crowded and expensive. Many companies waste budget on fragmented services: one vendor for SEO, another for ads, another for web, and no single owner of results. A dedicated Digital Marketing Strategist aligns market research, technical SEO, paid media, content and conversion optimisation around one growth plan, ensuring every pound spent contributes to revenue.
Alex Costin fills this role as a 360° specialist: he researches markets and competitors, builds high-performance websites, crafts content strategies, runs Google and Microsoft Ads, manages social channels and tracks performance in Google Marketing Platform and Adobe Experience Cloud. This eliminates handover friction and keeps accountability clear.
Alex Costin: strategy backed by record results
Alex’s positioning is simple: he combines deep expertise with measurable outcomes. His track record includes reducing PPC costs by up to 90%, achieving #1 rankings in as little as 11 days, and growing leads from around 20 per week to roughly 600 per week for clients. These results come from aligning market intelligence with technical excellence and continuous optimisation.
Core strengths include:
- Market research and competitor benchmarking
- Technical SEO audits and content strategy
- PPC planning, quality score optimisation and landing page design
- Full-stack web development (Drupal/Bootstrap, HTML/CSS, JS)
- Social media strategy with access to large influencer networks
- Analytics, dashboards and growth recommendations
This blend allows Alex to design strategies that are both ambitious and technically feasible, then implement them without relying on multiple vendors.
From strategy to implementation
Unlike strategists who stop at slide decks, Alex executes. He has delivered 100+ successful projects, 2000+ first-page keywords and 60+ websites, while training in-house teams on SEO, ads and analytics. Clients include UK public sector bodies, startups and established brands across nightlife, finance, ecommerce and events.
Typical engagement structure:
- Discovery: business goals, KPIs, current channels and constraints
- Research: market, customers, competitors and search data
- Strategy: prioritised roadmap with quick wins and long-term plays
- Build: websites, content, campaigns, tracking and automation
- Optimise: A/B tests, funnel fixes, bid and budget adjustments
This loop ensures strategies are living plans that adapt to performance data and algorithm changes.
Technical SEO and high-performance web
Alex specialises in technical SEO and “perfect” websites that score 100/100 on PageSpeed. He combines Drupal back-end with Bootstrap front-end to create fast, accessible, penalty-free sites that search engines and users love. These foundations lower CPCs, improve organic rankings and increase conversion rates.
His SEO work spans on-page audits, content planning, premium backlink strategies and off-page networks (including personal sites used to amplify authority). He has moved pages from 9th to 1st position and helped clients outrank industry leaders such as Bupa in competitive categories.
PPC and performance marketing
As a certified Google Ads Partner and Microsoft Advertising expert, Alex focuses on quality score, ad relevance and landing page experience. By improving these factors, he has cut clients’ cost per click by up to 90% versus competitor averages while increasing ROI. He manages campaigns in Google Marketing Platform, Microsoft Advertising and Adobe Experience Cloud, providing stakeholders with clear insights and growth suggestions.
Representative outcomes:
- 90% reductions in PPC costs through quality score and landing page optimisation
- 500%+ ecommerce sales growth for charity and retail clients
- Lead generation jumps from tens to hundreds per week
- Organic ranking improvements that sustain long-term traffic
These results are tied to rigorous testing, budget reallocation and continuous creative iteration.
Content, social and brand growth
Alex is also an experienced content strategist and social media manager. He creates trending, SEO-friendly content for blogs, newsletters, landing pages and social channels, and leverages his own networks (50k+ Twitter followers, 1m+ Facebook fans) to amplify reach. His creative background in graphic design and photography ensures brand assets are consistent and compelling.
He has trained in-house teams and public sector marketers on SEO, SEM and social best practices, enabling organisations to become more self-sufficient while maintaining high standards. This mentorship approach is valuable for London brands that want internal capability alongside external execution.
London-based, EU-experienced
Based in London and experienced across English, French, Italian, Spanish and other EU markets, Alex understands local search behaviour, cultural nuances and regulatory context. He has overseen digital operations for major UK events and worked with councils and agencies in Cardiff, London and Barcelona, making him well-suited to brands with national or international ambitions.
How to work with Alex
Engagements can be project-based (strategy + build) or ongoing (strategy, execution and optimisation). For London SMEs and scale-ups, Alex provides a cost-effective alternative to multi-vendor setups, consolidating research, creative, development and performance under one accountable strategist. Scope and pricing are tailored to your goals, with transparent reporting on traffic, leads, cost per lead and revenue impact.
