Professional identity
A marketer who understands the technology behind growth
Alex Costin describes himself as a full-stack digital marketer because his expertise is not limited to promotion. He can research a market, define a strategy, build or improve a website, create content, launch campaigns, measure performance and refine the funnel based on evidence.
His background began in development, which gave him a technical foundation that many marketing professionals do not have. That foundation later became central to his SEO and performance work: fast websites, clean front-end structures, strong technical SEO and landing pages designed to convert.
The result is a practical, end-to-end approach. Rather than treating SEO, paid media, web design and analytics as separate services, Alex treats them as connected parts of one growth system.

Career story
From developer to record-breaking SEO and growth strategist
Alex Costin’s career reflects a progression from hands-on technical work to strategic digital leadership. His CV presents a 17-year rise from developer to SEO and digital growth specialist, with experience across Europe and international markets.
Early work in code helped Alex develop the precision required for technical marketing. This background is visible throughout his later career: he does not only recommend improvements to websites and campaigns; he understands how to build, audit and optimize them. That combination of technical execution and marketing judgement became a defining feature of his professional profile.
Over time, his work expanded from development into SEO, paid search, content, branding, social media and analytics. His CV highlights multilingual campaigns in English, French, Italian, Spanish, Russian, Chinese and other markets, showing an ability to adapt strategies to different audiences and commercial environments.
Today, Alex positions his work around measurable outcomes: better rankings, stronger landing-page quality, lower acquisition costs, improved conversion rates and sustainable organic visibility. His public profile emphasizes results such as PPC cost reductions of up to 90 percent and pages reaching first position in as little as 11 days.
Foundation
Market research and business intelligence
Alex’s marketing process begins with research. His website describes market research work dating back to 2010, focused on turning raw data into clear, actionable business insight that supports profit-led decisions.
His research covers customer behaviour, competitor intelligence, market gaps, pricing opportunities and underserved segments. He uses both primary sources, such as surveys and interviews, and secondary data, including reports and databases, to build a fuller picture of a market.
The purpose is not research for its own sake. Alex’s approach is to prioritize insight by business impact and pass clear recommendations to decision-makers, turning information into rapid, profit-driving action.
Customer insight
Understanding customer habits, aspirations, attitudes and buying behaviour helps campaigns speak to real motivations rather than assumptions.
Competitor intelligence
Competitor analysis and SWOT-style assessment identify weaknesses, opportunities and areas where a brand can differentiate.
Market opportunity
Research helps reveal gaps, pricing opportunities and underserved customer segments across multiple languages and markets.
Commercial action
Insights are ranked by likely business impact, so teams can act quickly on the opportunities most likely to improve revenue.
Organic growth
Technical SEO and search visibility
SEO is one of Alex Costin’s central specialties. His public profile describes more than 17 years of experience improving rankings through technical audits, content strategy, backlinks, website optimization and AI-powered SEO campaigns.
His SEO work is not limited to keywords. It includes technical audits, site architecture, page speed, mobile performance, content ecosystems, internal linking, off-page authority and collaboration with internal teams. This broader view is important because rankings depend on both relevance and the technical health of a website.
Alex also emphasizes AI-driven search. As search behaviour evolves beyond traditional result pages, his approach includes optimizing for visibility across Google and AI search platforms, helping brands remain discoverable as discovery methods change.
His CV also highlights the creation of SEO content ecosystems and practical training for internal teams. This means clients are not only given recommendations; they can also develop the skills needed to maintain and grow their own search performance.
SEO focus areas
Reported results
- More than 2,000 keywords on the first page of Google.
- Pages reaching first position in as little as 11 days.
- 100/100 PageSpeed scores on optimized websites.
Build
Fast, accessible and conversion-ready websites
Alex Costin has more than 17 years of web development experience. His work focuses on fast, responsive and SEO-optimized websites that support business goals rather than simply looking attractive.
His technical toolkit includes HTML, CSS, JavaScript, React, WordPress, Drupal and custom CMS solutions. He is particularly associated with Drupal back ends combined with Bootstrap front ends, creating websites that are both flexible to manage and efficient for users.
Performance is a major theme in his work. His website and CV repeatedly reference 100/100 PageSpeed scores, mobile-friendly builds, strong Core Web Vitals and technically robust websites designed to scale.
He also describes building “feeder websites” to support off-page SEO, capture additional traffic streams and generate new leads. This shows how his development skills are used strategically, not only to launch a site but to strengthen a wider search and acquisition system.
Development principles
Paid growth
PPC, SEM and cost-efficient advertising
Alex has more than 12 years of experience as an SEM manager, focusing on improving quality scores, reducing PPC costs and increasing return on investment across paid search and paid social.
His paid-media approach connects advertising quality with landing-page quality. By improving both the ad experience and the page users arrive on, he aims to increase relevance, improve conversion rates and reduce wasted spend.
His public profile reports reductions in PPC costs of up to 90 percent and average cost-per-click levels as low as 10 percent of competitors’ spend in certain optimized scenarios. These figures reflect his emphasis on precision targeting, campaign structure, landing-page optimization and continuous performance monitoring.
He works with platforms including Google Ads, Microsoft Advertising and AI-supported campaign workflows. His experience also includes Google Ads Academy training across Search, Video, Mobile, Shopping, Display and Analytics.
Paid-media priorities
Paid-search performance depends on market, budget, competition and implementation. The figures above are reported by Alex Costin on his own website and CV.
Content and creative
Content, design, video and brand communication
Alex’s work extends beyond technical marketing into the creative assets that make a brand understandable, memorable and persuasive. His experience includes content strategy, copywriting, graphic design, photography and video editing.
As a content strategist, he develops plans that connect business objectives with audience needs. His content work includes SEO content, blogs, landing pages, newsletters, print assets and social media campaigns. The aim is to make content discoverable, useful and capable of converting readers into customers.
His creative background includes Adobe Creative Cloud and Figma. He creates branding, logos, social graphics, brochures, infographics and web visuals. He also has photography experience across still life, ecommerce and studio work, which supports stronger visual presentation across websites and campaigns.
Video is another important part of his skill set. Using tools such as Adobe Premiere Pro, After Effects and DaVinci Resolve, he edits content for YouTube, social platforms, advertisements and corporate communications. His approach treats video as storytelling with a commercial purpose: capturing attention, communicating value and encouraging action.
Content strategy
SEO-led planning, audits and editorial systems designed to attract and convert audiences.
Brand design
Visual identities, graphics and creative assets created with Adobe tools and Figma.
Photography
Studio, ecommerce and still-life photography used to strengthen web and social content.
Video editing
Video production and editing for social, advertising, YouTube and corporate channels.
Audience growth
Social media, email marketing and automation
Alex’s digital marketing work also covers audience development through social media, email marketing and automation. These channels help businesses stay visible, nurture leads and turn interest into revenue over time.
As a social media manager, he plans and coordinates brand activity to increase engagement and measurable growth. His public profile references a personal network of more than 50,000 Twitter followers and 1,000,000 Facebook fans, alongside experience building influencer networks and targeted paid campaigns.
In email marketing, his focus is on building funnels that convert. This includes segmented lists, high-quality copy, automated campaigns and performance tracking. The objective is to deliver relevant messages to the right audience at the right stage of the customer journey.
Marketing automation connects these activities. Alex designs systems that reduce manual work, nurture leads, streamline workflows and scale campaigns. Automation is treated as a way to improve efficiency while maintaining a more consistent customer experience.
Channel capabilities
- Social media strategy and community growth
- Email funnels, segmentation and campaign copy
- Marketing automation and lead nurturing
- Influencer networks and paid social campaigns
- Clear brand messaging and communications
Optimization
Analytics, testing and conversion rate optimization
Alex’s work is strongly data-led. He uses analytics to turn complex performance data into practical recommendations, helping businesses understand what is working, what is wasting budget and where growth opportunities exist.
His experience includes Google Marketing Platform, Microsoft Advertising and Adobe Experience Cloud. These platforms support campaign management, attribution, audience insight and performance monitoring across paid and organic channels.
Conversion rate optimization is a key part of his method. Rather than assuming that more traffic automatically means more revenue, he examines the full journey: how users arrive, what they see, where they hesitate and what prevents them from converting.
His public profile reports conversion-rate increases of more than 137 percent through systematic A/B testing and funnel optimization, along with cost-per-lead reductions of up to 79 percent. These outcomes illustrate the value of testing, measurement and iterative improvement.
The optimization loop
- Measure: Track traffic, engagement, conversions, costs and channel performance.
- Diagnose: Identify friction, weak messaging, technical issues and wasted spend.
- Test: Use A/B testing to compare landing pages, offers, layouts and calls to action.
- Improve: Apply the winning variation and refine the funnel further.
- Scale: Invest more confidently in the channels and messages proven to produce results.
