Why Choose Alex Costin?

A digital marketing strategist should understand how different channels work together. Alex’s experience covers the full digital marketing journey, from researching a market and defining an audience to building a website, creating content, launching campaigns and measuring results.

His CV describes him as a market, customer and competitor research analyst who investigates opportunities, customer behaviour trends and competitor strengths and weaknesses. Research findings are sorted by importance and shared with relevant decision-makers, helping businesses focus their time and budget on the activities most likely to create value.

Alex also combines strategic planning with direct implementation. He does not simply produce a roadmap and leave the business to execute it alone. He can create websites, SEO content, social media campaigns, paid advertising, performance reports and marketing processes that put the strategy into action.

Research-Led Digital Strategy

Effective strategy begins with understanding the market. Alex conducts market research to identify customer preferences, commercial trends, underserved segments and potential growth opportunities. He also performs competitor analysis and SWOT reviews to help businesses understand their position and develop a stronger advantage.

This research can support decisions about product development, pricing, brand messaging, website structure, content topics, advertising channels and market entry. Instead of choosing tactics because they are popular, Alex uses evidence to determine which activities are relevant to the audience and appropriate for the business.

Customer behaviour is an important part of this process. Alex investigates customer habits, aspirations and attitudes to understand why people choose one provider over another. These insights can improve buyer personas, customer journeys, landing pages, email campaigns and conversion paths.

SEO and Organic Growth

Alex is also a pioneering SEO specialist with more than 17 years of experience conducting audits, defining content strategies and working with internal teams to build powerful SEO content. His work covers technical SEO, on-page optimisation, off-page promotion, keyword research, content planning and website performance.

His CV records an organic growth strategy for Dunster House that helped important pages move from ninth position to second and first positions. Alex also trained and supervised a team of seven colleagues on technical and content SEO best practice.

SEO forms an important part of a wider digital strategy because it can attract valuable visitors without requiring a payment for every click. Alex creates search-focused content, improves landing-page quality and identifies more competitive keywords through market intelligence. His objective is to create sustainable visibility that supports leads, sales and brand authority.

Websites Built for Performance

A digital strategy cannot perform effectively when the website is slow, confusing or difficult to use. Alex combines website development with SEO and conversion optimisation to create responsive, accessible and technically sound websites.

He works with HTML, CSS, Drupal and Bootstrap and has experience designing websites that search engines can understand. His main website describes his ability to build fast websites with maximum PageSpeed performance, while his CV highlights the combination of Drupal back-end development and Bootstrap front-end design.

Alex can support new website builds, website rebuilds, landing-page improvements and technical upgrades. A strong website should load quickly, work across mobile devices, communicate value clearly and guide visitors towards meaningful actions such as an enquiry, booking or purchase.

Content, PPC and Social Media

Alex creates daily and trend-focused content for blogs, newsletters, leaflets and social media channels. His content strategy is designed to serve business goals and make information discoverable, relevant and persuasive.

He also has more than 12 years of experience managing search engine marketing. His CV records strategies that improved advertising quality scores and reduced PPC costs to as little as 90 percent below competitors’ average cost per click in certain campaigns. Strong landing pages, accurate targeting and continuous testing are central to improving paid search efficiency.

Alex’s social media experience includes managing influencer networks, setting up paid advertising and using established audiences to extend reach. His CV records access to networks of more than 50,000 Twitter followers and 1,000,000 Facebook fans, alongside experience creating social channels that increased outreach by 10,000 percent for Cardiff Jobs.

Performance Measurement and Automation

Marketing decisions should be based on results rather than assumptions. Alex is a Certified Performance Specialist who monitors platforms such as Google Marketing Platform, Microsoft Advertising and Adobe Experience Cloud. He provides stakeholders with reports, insights and growth suggestions that support ongoing improvement.

His experience includes tracking campaign performance, evaluating return on investment, identifying wasted advertising spend and improving reporting through tools such as Google Tag Manager. He can help businesses establish useful measurements for traffic, rankings, leads, sales, cost per acquisition, conversion rates and revenue.

Alex also uses marketing automation and AI-supported workflows to streamline content production, social media planning, campaign testing and performance analysis. Automation can reduce repetitive work while allowing teams to spend more time on creative and strategic decisions.
