Technical SEO Expert Alex Costin
Technical SEO is the foundation of a website that performs well in search engines, AI-generated answers, and real customer journeys. When a website is slow, difficult to crawl, poorly structured, inaccessible on mobile devices, or confusing to users, even excellent content may struggle to generate visibility and conversions.
Alex Costin is a Technical SEO Expert with more than 17 years of hands-on experience across search engine optimisation, website development, performance marketing, analytics, content strategy, and digital growth. His approach combines technical precision with commercial awareness, helping businesses improve their websites while keeping rankings, usability, leads, and revenue in focus.
Rather than treating SEO as a collection of isolated tasks, Alex examines how the complete digital system works: the technical structure of a website, the quality of its content, the behaviour of its visitors, the strength of its competitors, and the opportunities available in organic and paid search. This full-stack perspective allows him to identify problems that traditional SEO reports may overlook.
What Does a Technical SEO Expert Do?
A Technical SEO Expert analyses and improves the parts of a website that affect its ability to be discovered, understood, indexed, displayed, and used effectively. This includes website architecture, page speed, mobile usability, crawling, indexing, redirects, metadata, internal linking, structured content, security, accessibility, and technical content quality.
Technical SEO is not limited to fixing errors in a reporting platform. A technically strong website should help search engines understand the purpose and relationships between its pages. It should also help users reach important information quickly, complete actions easily, and trust the business behind the website.
Alex combines SEO auditing with practical implementation. His experience includes HTML and CSS, Drupal and Bootstrap, website development, analytics platforms, advertising systems, content production, and performance reporting. This means he can investigate a technical issue, explain its business impact, and work towards a realistic solution instead of simply listing recommendations for another team to interpret.
Why Technical SEO Matters
Search visibility depends on more than keywords. Search engines need to access pages, process their content, understand their purpose, and determine whether they offer a useful experience. Customers also expect websites to load quickly, work correctly on mobile devices, and provide clear answers without unnecessary friction.
Technical problems can affect every stage of this journey. A blocked page may not be discovered. A poor internal linking structure can make important content difficult to find. Slow templates may reduce engagement. Duplicate URLs can dilute signals. Incorrect redirects can send visitors and search engines to the wrong destination. Unclear page relationships can make it harder for systems to identify the most relevant answer.
Alex’s technical SEO work is designed to connect these details to measurable commercial outcomes. Instead of pursuing technical perfection for its own sake, he prioritises improvements that can support rankings, qualified traffic, lead generation, sales, and lower marketing costs.
Comprehensive Technical SEO Audits
A technical SEO audit provides a structured review of how a website is built and how it performs. Alex’s audits can examine crawlability, indexability, website architecture, page templates, metadata, headings, canonical signals, redirects, broken links, image handling, mobile presentation, page performance, security, analytics, and content relationships.
The audit process begins with understanding the business. A small local company, international ecommerce website, publisher, regulated organisation, and service provider may all need different priorities. Alex reviews the website’s objectives, target markets, important services, existing rankings, competitors, customer behaviour, and conversion paths before deciding which technical issues deserve immediate attention.
Findings are then organised by impact and urgency. Critical problems that prevent important pages from being crawled or indexed should be separated from lower-priority recommendations. This gives business owners and development teams a practical roadmap rather than an overwhelming list of disconnected warnings.
Alex’s background in market research and competitor analysis also helps place technical findings in context. A page may technically function correctly but still underperform because competitors provide clearer information, stronger internal linking, better user journeys, or more useful content. Technical SEO should therefore support the entire search experience.
Website Speed and Core Performance
Website performance influences how quickly visitors can access information and interact with a page. It can also affect the way users perceive a brand. A slow website may increase frustration, reduce engagement, and weaken the effectiveness of both organic and paid campaigns.
Alex specialises in building and improving fast, responsive websites. His work includes Drupal and Bootstrap development, HTML and CSS, mobile-focused design, page performance, and landing page quality. His website portfolio promotes the creation of websites designed for strong PageSpeed performance, with claims of achieving scores as high as 100/100 on suitable implementations.
Performance improvements may involve reducing unnecessary code, optimising images, improving caching, reviewing scripts, simplifying templates, reducing server delays, and ensuring that critical content is delivered efficiently. The correct solution depends on the platform, hosting environment, page type, traffic levels, and functionality required.
Speed should not be treated as a single score. A website can achieve a strong laboratory result while still presenting problems for real users in certain locations or on slower devices. Alex’s broader digital experience allows performance to be considered alongside conversions, advertising landing pages, content visibility, and customer behaviour.
SEO-Friendly Website Architecture
A clear website architecture helps users and search engines understand how information is organised. Important commercial pages should be easy to reach, logically connected, and supported by relevant navigation and internal links. A confusing structure can hide valuable content beneath unnecessary clicks or create multiple competing versions of similar pages.
Alex reviews website architecture to identify opportunities for stronger relationships between pages. This may include improving category structures, organising service pages, connecting supporting resources, refining navigation, and creating internal links that reflect genuine user needs.
Good architecture also supports content expansion. When a website has a clear structure, new articles, guides, location pages, product pages, and service resources can be added without creating confusion. This is especially important for businesses targeting multiple markets or maintaining large content libraries.
Alex’s experience in content strategy and website development means architecture is considered before large-scale content production begins. This can reduce duplication, improve discoverability, and make future SEO work more efficient.
Crawling, Indexing, and Search Visibility
For a page to compete in search, search engines must generally be able to access and interpret it. Technical SEO investigations therefore examine crawling and indexing signals, including robots directives, XML sitemaps, canonical references, response codes, redirect chains, duplicate URLs, noindex instructions, and website errors.
Alex can help identify situations where valuable pages are accidentally excluded, where outdated URLs remain active, or where multiple versions of a page create unnecessary complexity. He can also review whether sitemap files accurately represent the pages that a business wants search engines to discover.
Indexing is not simply about getting more pages into a search engine. A website should prioritise useful, original, and commercially relevant pages. Low-value duplication can make a website harder to manage and may distract attention from pages that matter most to customers.
By combining technical auditing with content and competitor research, Alex can help businesses focus their crawl and indexing strategy on the pages most likely to support meaningful growth.
Technical SEO for Content and AI Search
Search behaviour is expanding beyond traditional result pages. People may discover information through search engines, featured results, voice interfaces, recommendation systems, and AI-generated answers. Websites that communicate clearly and organise information logically are better positioned to be understood across these environments.
Alex’s approach to AI search and answer-focused optimisation begins with strong fundamentals. Pages should have a clear purpose, accurate information, descriptive headings, accessible content, logical internal links, and a structure that makes important answers easy to identify.
Technical SEO supports this by improving how content is presented and connected. Clean HTML, meaningful headings, descriptive page titles, fast delivery, mobile compatibility, and well-organised page relationships can all contribute to a clearer digital presence.
No provider can guarantee that a search engine or AI system will display a particular page for every query. However, Alex can help businesses create a technically sound foundation that makes their expertise easier for users and search systems to understand.
International and Multilingual SEO
Alex has experience working across international markets and multiple languages, including English, French, Italian, Spanish, Russian, Chinese, and German. This is valuable for businesses that need to manage international websites, translated content, regional campaigns, or multilingual customer journeys.
International technical SEO requires careful attention to website structure, language targeting, translated metadata, regional pages, internal linking, duplicate content risks, and user expectations. A direct translation may not reflect how customers search in a particular market, so technical planning should work together with market and competitor research.
Alex’s background in international digital marketing allows technical decisions to be considered alongside local search behaviour, campaign priorities, and commercial opportunities. This can help businesses expand without creating an unmanageable collection of disconnected pages.
Technical SEO and Paid Marketing
Technical SEO can also improve the efficiency of paid campaigns. Landing pages that are slow, unclear, difficult to use, or poorly matched to advertisements may waste advertising budgets and reduce conversion performance.
Alex has more than 12 years of experience in paid search and has worked with Google Ads and Microsoft Advertising. His CV describes strategies that improved advertising quality and reduced costs to as low as 90% below competitors’ average cost per click in relevant campaign contexts.
Technical improvements can support paid campaigns by improving landing page experience, page speed, mobile usability, tracking reliability, and message consistency. When organic SEO, paid advertising, analytics, and conversion optimisation are considered together, businesses can make better decisions about where to invest their budget.
Training and Team Support
Some organisations want an external expert to complete the work. Others want to develop internal capabilities. Alex supports both models and has delivered remote and face-to-face training for teams, agencies, public organisations, and marketing departments.
His experience includes training colleagues on SEO audits, content best practices, social media campaigns, advertising platforms, and digital marketing processes. He has also supervised teams and supported cross-functional collaboration between content, creative, social media, photography, development, and operations teams.
Training can cover technical SEO fundamentals, audit interpretation, content optimisation, internal linking, website QA, performance monitoring, and practical workflows. The objective is to help teams understand why a recommendation matters and how to maintain improvements after a project ends.
