What our on-page SEO includes
Keyword mapping
One clear primary search per page, so pages do not compete with each other and every buyer search has a home.
Titles, meta and headings
Title tags, meta descriptions and heading structure written to rank and to earn the click.
Content optimisation
Rewriting and expanding pages to answer buyer questions fully, with answer-first sections AI search can quote.
Internal linking
Links between related pages that spread authority and help users and crawlers find your key pages.
Structured data
Schema markup for organisation, services, products, FAQs, articles and breadcrumbs, validated and error-free.
Speed and Core Web Vitals
Image, code and loading fixes that make pages fast on mobile, done by our own developers.
What to expect when you hire
Start with search intent
Ranking depends on whether a page gives searchers what they came for. We check what Google already ranks for each target search, whether that is guides, service pages or comparisons, and shape your page to match that intent while saying something more useful.
Fix cannibalisation and thin pages
Many sites have several weak pages chasing the same search. We merge, redirect or differentiate them so one strong page ranks, and expand or remove thin pages that hold the rest of the site back.
Write for people and AI answers
Clear headings, a direct answer near the top, specific facts and well-structured lists help both readers and AI assistants such as Google AI Overviews and ChatGPT. We avoid keyword stuffing, which reads badly and can hurt rankings.
Changes made, not just recommended
Most on-page audits end as a spreadsheet no one has time to act on. Our developers implement fixes in Next.js, React, WordPress, Shopify and most other platforms, then we track the effect in Google Search Console.
