SEO Specialist Excellence
Landing page quality refers to how well a page fulfils a user’s intent, loads quickly, and is technically sound across speed, accessibility and structure. High‑quality landing pages are not only easier for visitors to read and interact with, but they also send strong positive signals to search engines and AI‑driven search overviews.
When a website consistently delivers high‑quality landing pages, it ranks higher in organic search and gains more visibility in AI‑generated answers and snippets. Search engines reward sites that offer fast, accurate, accessible content, so landing page quality is now a core ranking and visibility factor, not just a “nice‑to‑have”.
To see this excellence in practice, visit the following PageSpeed Insights audits where Alex Costin’s projects score 100/100 across Performance, Accessibility, Best Practices and SEO: alexcostin.com, plato.alexcostin.com, and deceneus.alexcostin.com. In each report, the 100/100 scores demonstrate how technical precision directly translates into better search and AI visibility.

Bringing Alex Costin on board as your SEO Specialist creates a powerful, end‑to‑end engine for growth, from market research and technology to AI‑driven content and performance measurement. Below is how each pillar of his work delivers a competitive edge for London businesses.
Market Research
Alex uses both primary and secondary data to uncover hidden market opportunities, customer behaviour patterns and competitor weaknesses. By translating this intelligence into actionable, ROI‑focused strategies, he helps businesses position themselves where competitors are weakest and demand is strongest.
Website Development
A new website built on Drupal and Bootstrap, delivered in as little as two weeks on a fresh server, can easily outperform template‑based WordPress sites used by most local, regional and national competitors. With 100/100 PageSpeed scores, excellent Core Web Vitals and pixel‑perfect UX, these sites gain an instant advantage in both search rankings and visitor retention.
SEO
Deep keyword research combined with maximum landing page quality ensures that every page is built to rank and convert. Off‑page backlinks from Alex’s 5000+ blog posts and his partners’ 5000+ sites create a powerful authority network that very few UK businesses can match, giving clients a durable SEO advantage over time.
Artificial Intelligence
Alex leverages AI at an expert level to create engaging content, automate social‑media campaigns and optimise workflows, which drastically reduces the time and cost of manual repetitive tasks. This approach often eliminates the need to hire additional employees or third‑party agencies just to maintain a constant digital presence.
Performance
Weekly performance reports allow Alex to review campaigns, identify quick wins and bottlenecks, and build a prioritised list of improvements. He then discusses these insights with decision makers, fine‑tunes the strategy and implements changes, creating a continuous cycle of improvement that steadily increases ROI.
