The short answer

Optimise a blog post by choosing a clear topic and intent, writing a strong title and H1, structuring it with headings, covering the subject thoroughly, and adding internal links. There is no ideal length; be as long as the topic needs. Internal links connect it to related content and key pages. AI works best supporting a writer, not replacing one. And a post works best as part of a planned content strategy.

How to optimise a blog post, and how long it should be

You optimise a blog post by choosing a clear topic and intent, writing a strong title and H1, structuring it with headings, covering the subject thoroughly, and adding internal links, and usefulness comes first. Because a blog post ranks by answering a real question well, writing genuinely helpful content is the foundation, with on-page details supporting it. There is no ideal length; a blog post should be as long as it needs to be to answer the topic fully, no more and no less. Length follows the topic; because padding to hit a word count adds no value, matching depth to what the query needs is what matters, not a target number of words. For the wider craft of planning and writing posts, our content and blogging guide goes deeper.

Links, AI and strategy

Internal links, using AI, and content strategy

Internal links help by connecting a blog post to related content and to relevant service or product pages, guiding readers and spreading context. They tie your content together; because linked content is easier to discover and understand, sensible internal linking strengthens both the post and the pages it links to. AI can support blog writing by helping with research, outlines and drafts, but the value comes from a real person adding expertise, accuracy and judgement. Search rewards useful content, not how it was made; because thin, mass-produced AI content is treated as spam while genuinely helpful content is not, AI works best as a tool that supports a writer rather than replaces one. A blog post works best as part of a planned content strategy, covering distinct topics that support your main pages and each other. It should not exist in isolation; because coordinated content builds topical strength, planning posts around a clear strategy makes each one more effective, and helps you avoid keyword cannibalisation.
