SEO Specialist London

SEO Specialist London

Search engine optimization can help businesses attract qualified visitors without paying for every click, but sustainable results require much more than adding keywords to a webpage. Alex Costin is an SEO Specialist London businesses can work with to improve technical performance, strengthen content, build authority and create a search strategy connected to revenue.

Alex brings more than 17 years of SEO experience and over 17 years of wider digital marketing expertise. His skills include technical SEO, content strategy, website development, PPC, analytics, market research, social media, email marketing, marketing automation and conversion rate optimization. This combination allows him to examine the complete route from search result to customer action.

Technical SEO that supports growth

Technical SEO creates the foundation for visibility. Search engines need to access, understand and evaluate a website, while visitors need pages that load quickly, work on mobile devices and make information easy to find. Alex can audit the technical structure of a website and identify issues that may limit rankings, usability or conversions.

His CV describes conducting on-page SEO audits to maximise the SEO performance of important pages. Technical reviews may consider page structure, metadata, internal links, mobile display, indexing, redirects, content organisation and website speed. Correcting these issues can make a site clearer for search engines and easier for customers to use.

Alex’s website focuses on fast, responsive and SEO-optimized websites and promotes 100/100 PageSpeed targets. Page speed is only one part of SEO, but a technically efficient website can provide a stronger experience for both organic visitors and people arriving through paid campaigns or social media.

Research before optimization

SEO decisions are more effective when they are based on a clear understanding of the market. Alex’s CV describes researching market opportunities, customer behaviour trends and competitors, then sorting findings by importance and presenting them to relevant decision-makers.

This research can reveal the language customers use, the services they seek, the questions they ask and the weaknesses in competing websites. It may also identify underserved segments, valuable local opportunities or commercial keywords that larger competitors have overlooked.

Alex’s website states that he has more than 15 years of market research experience across English, Italian, Spanish and French markets. International research is particularly important for companies that target several countries, because search intent, terminology, competition and customer expectations can vary significantly by location.

Content strategies that earn visibility

Content is central to modern SEO, but publishing more pages does not automatically produce better results. Each piece should serve a clear audience need and support a business objective. Alex can develop content strategies that align topics, search intent, customer questions and conversion opportunities.

His website describes more than 15 years of experience creating content strategies, auditing existing content and producing SEO content, blog posts, landing pages and AI-powered campaigns. His CV also identifies him as a content writer who creates material for blogs, newsletters, leaflets and social media channels.

A useful content programme may include informational articles for early research, comparison pages for users evaluating options, service pages for high-intent searches and supporting resources that answer objections. Internal links can guide visitors between these assets and help search engines understand how the website’s topics relate to one another.

On-page and off-page SEO

On-page SEO improves the relevance and clarity of a website’s own pages. Alex can review titles, headings, copy, images, links, calls to action and page structure to ensure that content serves both users and search engines. The goal is to communicate the page’s purpose clearly while providing a useful experience.

Off-page SEO focuses on signals beyond the website, including relevant mentions and backlinks. Alex’s CV describes creating off-page backlinks that promote website pages and support on-page SEO. His website promotes ethical, data-driven and white-hat backlink strategies designed to build authority safely.

Link building should be approached carefully. Quantity alone does not guarantee value, and low-quality or irrelevant links can create risk. A stronger approach focuses on relevance, editorial quality, natural placement and a sustainable relationship between the linked page and the referring website.

Evidence from previous projects

Alex’s CV records SEO work across a wide range of organisations and industries. At Dunster House, he developed an organic growth strategy, performed on-page audits, identified opportunities through market intelligence and competitor insight, created off-page backlinks and trained a team of seven colleagues on SEO best practices.

The CV reports that important pages grew from ninth position to second and first positions. At Promote.Barcelona, Alex created a website, SEO strategy and paid and organic social campaigns, with the company shortly reaching first position on Google and Bing for its goals. Results for a new project will depend on competition, technical condition, content quality, authority and implementation.

His website reports more than 2,000 first-page Google keywords, more than 100 successful projects launched and more than 60 successful websites created. These figures are published by Alex and provide an indication of the scale of experience behind his services.

SEO, PPC and conversions together

Organic search should not be managed in isolation from the rest of digital marketing. SEO can attract visitors, but landing pages, messaging, forms and follow-up processes determine whether those visitors become leads or customers. Alex’s PPC and conversion optimization expertise helps connect search visibility with commercial performance.

His website reports conversion-rate increases of more than 137% and cost-per-lead reductions of up to 79% through systematic testing and funnel optimization. It also promotes PPC strategies that reduce costs by up to 90%. These are published performance claims, not guaranteed outcomes; results vary according to the market, starting position, budget, offer and implementation.

By reviewing traffic quality and conversion behaviour, Alex can help determine whether the priority should be creating new content, improving existing pages, fixing technical issues or refining the conversion journey. This prevents businesses from measuring SEO success only by rankings while overlooking revenue and lead quality.

Training and practical implementation

Businesses often want to develop internal capability rather than depend indefinitely on an external supplier. Alex’s CV records tutorial sessions, remote and face-to-face training, team supervision and mentoring. He has trained in-house employees, agency workers and public-sector marketing teams on SEO, SEM, social media and digital best practices.

Training can cover SEO audits, keyword research, content planning, technical checks, internal linking, performance reporting and safe link-building principles. Alex can also help teams establish repeatable processes so that optimization continues after the initial project.

International SEO experience

Alex has worked on campaigns involving Spain, Portugal, Germany, France, China, Russia and the United States, alongside English, French, Italian and Spanish-language experience. This international background can support businesses expanding into new markets or managing multilingual websites.

International SEO requires careful attention to local search behaviour, terminology, content adaptation, targeting and technical structure. A direct translation may not reflect how people search or what persuades them to contact a business. Market-specific research helps create more relevant campaigns.
