Where to focus your technical SEO effort for real, measurable impact.

Start with crawlability

Before optimising anything, make sure Google can reach your important pages. Check your robots.txt, XML sitemap, internal linking and crawl budget. Orphaned pages and accidental blocks are the most common — and most fixable — problems we find.

Core Web Vitals

Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift are ranking signals and, more importantly, user-experience signals. Compress images, defer non-critical JavaScript, and reserve space for dynamic elements to stop layout shift.

Indexation hygiene

More indexed pages isn't better — the right pages indexed is. Use canonical tags correctly, noindex thin or duplicate pages, and monitor Search Console's coverage report monthly.

Structured data

Schema markup helps Google understand your content and can win rich results. Prioritise Organisation, Article, FAQ and Product schema where relevant — and validate it before you ship.
