Finding the Best SEO Specialist London businesses can trust is essential when search visibility, qualified traffic and revenue are growth priorities. Alex Costin is a data-driven SEO and digital marketing specialist with more than 17 years of hands-on experience helping businesses improve organic rankings, website performance and return on investment.

Unlike agencies that divide SEO, content, paid advertising and website development between separate departments, Alex combines these disciplines in one integrated service. This full-stack approach helps identify the real causes of poor performance, from technical website issues and weak content to irrelevant keywords, slow landing pages and inefficient advertising campaigns.

Technical SEO Built Around Performance

Alex specialises in technical SEO audits designed to uncover the barriers preventing a website from reaching its potential. These audits can examine website structure, page quality, mobile performance, content opportunities, indexing, user experience and technical implementation. The objective is not simply to produce a report, but to turn data into practical improvements that support rankings, conversions and long-term growth.

With experience in HTML, CSS, Drupal, Bootstrap, WordPress and other digital marketing technologies, Alex can work closely with developers or directly on suitable website projects. His approach focuses on building fast, accessible, secure and search-engine-friendly websites. Website speed and landing-page quality are treated as important parts of the wider marketing strategy rather than isolated technical tasks.

Alex’s website highlights a focus on high-performing websites, including projects designed to achieve excellent PageSpeed results. Better performance can improve the experience for visitors while supporting stronger engagement and more efficient paid campaigns.

SEO Strategies That Support Growth

Effective SEO requires more than adding keywords to pages. Alex begins by understanding a company’s objectives, customers, competitors and market opportunities. His market research experience includes analysing customer behaviour, competitor activity, underserved segments and commercial opportunities. These insights help shape SEO strategies around realistic search demand and business value.

Alex has more than 17 years of experience conducting SEO audits, defining content strategies and working with in-house teams to create powerful SEO content. His work covers on-page optimisation, technical improvements, content development and off-page SEO. He also creates and promotes content on relevant websites to support a broader authority-building strategy.

His CV records measurable SEO achievements across different industries. At Dunster House, Alex developed an organic growth strategy, identified opportunities through market and competitor intelligence, created backlinks and helped important pages improve from ninth position to second and first positions. He also trained and supervised a team of seven colleagues on technical and content SEO best practices.

Content and Multilingual Marketing

Search engines reward content that is useful, relevant and aligned with the needs of a specific audience. Alex combines SEO knowledge with extensive content strategy and writing experience to help businesses produce content for websites, blogs, newsletters, landing pages and social media channels.

His experience includes working across English, French, Italian, Spanish and other international markets. This multilingual capability can help companies reach customers in London, the wider United Kingdom and overseas markets while maintaining consistent brand messaging. Content can be planned around customer questions, commercial intent, competitive gaps and the stages of the buying journey.

Alex can also train internal teams so they become more self-sufficient. His CV includes tutorial sessions delivered remotely and face to face, as well as team training in SEO, social media and paid advertising. This makes his service suitable for businesses that want expert implementation, strategic direction or knowledge transfer.

SEO and PPC Working Together

Organic SEO and paid search should not operate in isolation. Alex has more than 12 years of SEM experience and has worked with Google Ads and Microsoft Advertising. His campaigns focus on improving quality scores, reducing wasted spend and increasing return on investment through stronger keyword selection, ad relevance and landing-page quality.

According to Alex’s professional profile, his strategies have reduced costs to as little as 90% below competitors’ average cost per click in suitable campaigns. His CV also records an 8% ROI increase for a major car insurance supplier and experience optimising campaigns across Spain, Portugal, Germany, France, China, Russia and the United States.

This combined SEO and PPC perspective helps businesses make better marketing decisions. Paid search data can reveal valuable keywords and customer intent, while organic growth can reduce reliance on continually increasing advertising costs.
