SEO Specialist London

Businesses looking for an SEO Specialist London can work with Alex Costin to improve search visibility, attract qualified organic traffic and turn website visitors into customers. Alex combines more than 17 years of SEO experience with technical website development, content strategy, market research, competitor analysis, paid advertising, analytics and conversion rate optimisation.

Search engine optimisation is not simply about adding keywords to pages. Sustainable SEO requires a fast, accessible website, useful content, accurate technical foundations, trustworthy authority signals and a clear understanding of customer intent. Alex brings these elements together to create practical SEO programmes focused on rankings, traffic, leads, sales and return on investment.

Technical SEO with a commercial focus

Technical SEO determines how easily search engines can crawl, interpret and evaluate a website. It also affects the experience people have after clicking a search result. Alex conducts SEO audits to identify technical issues that may limit visibility, reduce usability or prevent important pages from reaching their potential.

His technical capabilities include HTML, CSS, JavaScript, React, WordPress, Drupal, Bootstrap and custom CMS solutions. This development background allows him to understand how websites are built and communicate effectively with developers, designers and internal marketing teams. Instead of treating technical SEO as a separate report, Alex can connect recommendations to practical website improvements.

Page speed is another important part of his approach. Alex promotes fast, responsive and SEO-optimised websites, including websites designed to achieve 100/100 PageSpeed scores. Improving performance can support mobile usability, reduce friction and create a stronger foundation for both organic search and paid campaigns.

Research before optimisation

Strong SEO starts with understanding the market. Alex describes himself as a market and competitor research analyst who studies customer behaviour, market opportunities and competitor strengths and weaknesses. This research helps identify the topics, services, products and search opportunities most likely to support commercial growth.

Keyword research should not focus only on the highest-volume phrases. Competitive terms may attract attention but produce little business value if they do not match the company’s services or customer intent. Alex uses market intelligence to identify relevant and more competitive opportunities, including terms that may provide a realistic route to qualified traffic.

Research can also reveal gaps in competitor content, underserved audiences, pricing opportunities and unanswered customer questions. These insights help businesses create pages that are more useful than generic articles designed solely to include keywords.

Content strategies that attract customers

Alex has more than 15 years of experience developing content strategies and creating content for websites, blogs, newsletters, leaflets and social media channels. He can help businesses plan content that serves specific goals, such as increasing visibility, answering objections, supporting a buying decision or generating enquiries.

Effective SEO content should satisfy the searcher’s purpose quickly and clearly. A service page needs to explain what is offered, who it helps, why the business is credible and what the visitor should do next. An educational article should provide useful information while guiding readers towards relevant services or resources.

Alex’s website states that he creates SEO content, blog posts, landing pages and AI-powered campaigns for English, Italian, Spanish and French markets. His multilingual experience can help international businesses adapt content to local language, customer expectations and search behaviour rather than relying on direct translation alone.

On-page optimisation and user experience

On-page SEO includes page titles, headings, internal links, metadata, content structure, image information and the way important topics are explained. Alex can review these elements to ensure that pages are clear for users and easier for search engines to understand.

On-page optimisation should also support conversions. A page that ranks well but provides no clear next step may generate traffic without producing business results. Alex combines SEO with conversion rate optimisation to improve calls to action, navigation, forms, trust signals and landing page relevance.

His website describes systematic A/B testing and funnel optimisation that increased conversion rates by over 137%. Results vary by website and market, but this illustrates the value of measuring what visitors do after arriving from search. Organic growth becomes more valuable when it produces qualified enquiries, sales or other meaningful actions.

Building authority safely

Off-page SEO can help strengthen a website’s authority and visibility. Alex creates off-page content and backlinks to support on-page optimisation, while promoting ethical, data-driven and white-hat link-building strategies on his website. The purpose is to build credible connections rather than rely on risky shortcuts that could create long-term problems.

Relevant backlinks can help search engines understand the subject and reputation of a website. However, quantity alone does not guarantee improvement. Link quality, relevance, editorial context, destination page quality and the overall health of the website all matter.

Alex’s CV records creating off-page backlinks that helped pages at Dunster House move from ninth position to second and first positions. He also describes creating feeder websites to support off-page SEO and acquire additional traffic and clients. Any link-building campaign should be tailored to the business, its market and its risk tolerance.

Proven SEO experience

Alex has worked on SEO programmes for ecommerce businesses, agencies, public-sector organisations, local services, financial companies and international campaigns. His CV records helping a health insurance page compete with UK leader Bupa through on-page and off-page SEO. It also describes creating websites and strategies that achieved first-page positions across Google and Bing.

His website reports more than 2,000 first-page Google keywords, over 60 successful websites and more than 100 successful projects. It also highlights experience across 10 worldwide markets. These figures demonstrate the breadth of his work, while each individual project should still be evaluated against its starting position, competitive environment and business objectives.

Alex has also trained in-house teams in technical and content best practices. At Dunster House, he remotely trained and supervised seven colleagues on SEO implementation. Training can help businesses become more self-sufficient and ensure that good practices continue after an initial optimisation project.

SEO, PPC and analytics together

Alex does not treat SEO as an isolated marketing channel. His experience includes more than 12 years of SEM, Google Ads, Microsoft Advertising, email marketing, social media, analytics, marketing automation and website development. This wider view helps businesses understand how organic search interacts with paid advertising and other customer acquisition channels.

For example, PPC data can reveal valuable search terms and customer messages that inform SEO content. Organic pages can support paid campaigns by providing relevant landing page experiences. Analytics can show which search visitors engage, convert and generate revenue. Marketing automation can nurture leads who are not ready to buy during their first visit.

Alex’s performance-specialist background includes monitoring Google Marketing Platform, Microsoft Advertising and Adobe Experience Cloud performance. He uses reports and analysis to identify opportunities, pinpoint problems and recommend improvements based on evidence.

SEO for London businesses

Local and London-based companies often need visibility for specific services, locations and customer groups. Alex can assess local search intent, competitor presence, service-area pages, technical performance and conversion opportunities. A local SEO strategy should make it easy for potential customers to understand what the business offers, where it operates and how to make contact.

For companies serving wider UK or international markets, the strategy may involve separate content structures, regional research and multilingual optimisation. Alex’s experience across European and global markets supports a more flexible approach than a one-size-fits-all campaign.
