Internal links should guide a person to the next useful answer. A web design article can link to a web design service, a redesign checklist and a contact page because those destinations naturally continue the journey.
Use descriptive anchor text. Links such as ‘technical SEO audit’ or ‘e-commerce development’ explain what the destination offers better than generic phrases like ‘click here’.
Review hub pages regularly. Services, guides, tools and blog articles should link to one another where the relationship is genuinely useful, while avoiding repetitive or forced link blocks.
What to do next
Choose the one improvement most likely to reduce friction for a valuable user journey. Measure the result, learn from it and build from there.
