Core SEO Services Delivered by Alex Costin

Alex’s SEO work covers the full funnel, from technical foundations to content that ranks and converts.

Technical SEO Audits & Site Optimisation

Every successful SEO campaign starts with a robust technical base. Alex performs comprehensive SEO audits to identify crawl issues, indexation gaps, duplicate content, structured data opportunities, and Core Web Vitals bottlenecks. He then implements fixes that improve site health, user experience, and ranking potential.

His development background allows him to go beyond recommendations: he can directly optimise templates, implement schema markup, refine internal linking, and ensure mobile‑first performance that search engines reward.

Keyword Strategy & Market Intelligence

Alex treats keyword research as market research. He analyses customer behaviour, competitor positioning, and search intent to uncover high‑value opportunities that others miss. This includes long‑tail terms with strong commercial intent, local London queries, and multilingual keywords for businesses targeting international audiences.

By focusing on keywords that drive revenue rather than just traffic, Alex ensures your SEO investment delivers real business growth.

On‑Page SEO & Content Strategy

Content is the engine of organic growth. Alex crafts SEO‑focused content strategies that align with your business goals, mapping topics to the buyer journey and prioritising pages with the highest ROI potential.

He creates and optimises:

• Service and product pages that rank and convert
• Blog posts and guides that build topical authority
• Landing pages with 100/100 PageSpeed for both SEO and PPC
• AI‑enhanced content workflows to scale output without sacrificing quality

His content is designed to satisfy search intent, earn links naturally, and support broader brand visibility across Google and AI‑driven search platforms.

Off‑Page SEO & Premium Backlink Building

Authority matters. Alex builds clean, white‑hat backlink profiles using ethical outreach, digital PR, and content‑led link acquisition. He offers structured backlink packages (from 1,000 to 10,000 links) tailored to your market competitiveness and growth stage.

These campaigns strengthen domain authority, improve rankings for competitive keywords, and future‑proof your site against algorithm updates. For London businesses in crowded sectors, this off‑page work is often the difference between page two and page one.

Local SEO for London Businesses

If you serve customers in London, local SEO is essential. Alex optimises Google Business Profile listings, builds local citations, and creates location‑specific content to capture “near me” searches and map pack visibility.

He also aligns local SEO with broader organic strategy so that city‑wide and neighbourhood‑level queries both contribute to your growth.

Beyond SEO: Full‑Stack Digital Marketing

What truly sets Alex apart as a top SEO specialist London is his ability to integrate SEO with other channels for compounded results.

• PPC Optimisation: He reduces cost per click by improving Quality Score through better landing pages, ad relevance, and keyword selection—often cutting costs by 50–90%.
• Conversion Rate Optimisation (CRO): Using systematic A/B testing and funnel analysis, Alex increases conversion rates by over 137% for many clients.
• Web Development: He builds fast, secure, SEO‑friendly websites on Drupal and Bootstrap that load instantly and rank well.
• Analytics & Reporting: Clear dashboards and insights keep stakeholders informed on what’s working, what’s not, and where the next growth opportunity lies.

This holistic approach ensures that every pound spent on marketing works harder, with SEO at the core.

Alex’s portfolio speaks for itself:

• 100+ successful projects launched across multiple industries
• 2,000+ first‑page keywords achieved for clients on Google
