Why Choose a Technical SEO Company Led by Alex Costin
When businesses search for a Technical SEO Company, they often expect a team of specialists handling separate tasks: one for audits, another for content, and yet another for paid ads. Alex Costin flips that model by offering a rare combination of 17+ years of hands-on technical SEO expertise alongside full-stack digital marketing capabilities that most agencies split across multiple departments.
This means you get a single point of accountability for everything from perfect PageSpeed scores and penalty-free website builds to content strategy, premium backlinks, and PPC campaigns that can reduce costs by up to 90%. For London-based business owners and international brands alike, this integrated approach translates into faster results, lower overheads, and measurable ROI growth without the typical agency bloat.
What Makes Alex Costin Different from Other Technical SEO Companies
Most Technical SEO Companies focus narrowly on fixing crawl errors, improving site speed, or building backlinks. Alex Costin goes further by combining technical perfection with market intelligence, creative design, and performance marketing under one roof.
Full-Stack Expertise Under One Roof
Alex is not just an SEO specialist; he is a 360° Digital Marketing Expert with proven success in Technical SEO Audits that maximize SEO scores and fix penalties, Web Development using Drupal/Bootstrap for 100/100 PageSpeed scores, Content Strategy that drives organic rankings and user engagement, PPC Optimization that slashes costs by up to 90% while boosting ROI, Social Media Management leveraging 50K Twitter and 1M Facebook fans, and Marketing Automation and Conversion Rate Optimization (CRO) that increase conversion rates by over 137%.
This breadth of skill means your website is not just technically sound—it is strategically positioned to dominate search results, convert visitors, and scale efficiently.
Record-Breaking Results, Not Just Promises
Alex Costin's track record includes ranking pages on the 1st position in just 11 days, reducing PPC costs by up to 90% compared to competitors, growing organic traffic from 9th to 1st position through targeted OFF-PAGE SEO, increasing e-commerce sales by 500% for Oxfam with just one day per week of work, and scaling leads from around 20 to around 600 per week for Away Days through innovative SEO and social strategies.
These are not theoretical claims—they are documented outcomes from real campaigns across the EU and UK markets.
Core Technical SEO Services Offered by Alex Costin
1. Comprehensive Technical SEO Audits
Alex performs deep-dive ON-PAGE SEO audits to identify and fix issues that hold your site back from ranking. This includes crawlability and indexation checks, site speed and Core Web Vitals optimization, mobile-friendliness and responsive design validation, structured data and schema markup implementation, and internal linking and URL structure improvements.
The goal is to create a penalty-free, maximum-performance website that search engines love and users trust.
2. High-Performance Web Development
Unlike many SEO consultants who rely on developers, Alex builds websites himself using Drupal back-end and Bootstrap front-end, ensuring perfect alignment between technical SEO and user experience.
Benefits include 100/100 PageSpeed scores out of the box, clean semantic HTML/CSS that search engines can easily parse, fast load times that reduce bounce rates and improve rankings, and seamless integration with social platforms and analytics tools. This "perfect website" approach means you avoid the common pitfall of having great content trapped in a poorly coded site.
3. Strategic Content and OFF-PAGE SEO
Alex does not stop at technical fixes. He creates daily trending content and builds OFF-PAGE backlinks through his own network of websites and influencer connections.
Key tactics include publishing high-authority backlinks on personal and partner sites, crafting content that aligns with customer behaviour trends, using market intelligence to target competitive keywords, and training in-house teams to maintain SEO best practices long-term. This dual focus on ON-PAGE and OFF-PAGE SEO ensures sustainable growth, not just short-term spikes.
4. PPC and SEM Optimization
As a Certified Google Ads and Microsoft Advertising Partner, Alex has helped clients reduce Cost Per Click (CPC) by up to 90% while improving Quality Scores and ROI.
He achieves this by optimizing landing pages for maximum relevance and speed, refining ad copy and keyword targeting based on performance data, eliminating wasted spend on bot traffic and irrelevant clicks, and aligning paid campaigns with organic SEO strategies for synergy. The result is a leaner, smarter ad budget that works harder for your business.
