Blog SEO
Blog SEO is the practice of planning, writing and optimising blog posts so they rank in search engines and attract relevant readers. Done well, a blog answers the questions your audience searches for, builds topical authority and supports the pages that generate sales.
What blog SEO covers
Blog SEO is not a separate discipline. It applies normal on-page SEO to articles, plus some blog-specific concerns: topic selection, publishing consistency, category and tag pages, archives and keeping older posts accurate.
Why a blog helps SEO
- It lets you target informational keywords that sales pages cannot rank for.
- Groups of related posts build topical authority, showing depth on a subject.
- Useful posts attract links and mentions more easily than service pages.
- Posts can link to commercial pages, passing authority and guiding readers towards a purchase.
How to optimise a blog post
- Start with keyword research and pick one main topic per post. Check the results page to see what format searchers expect.
- Write a clear title tag and H1 that include the topic in natural wording.
- Answer the main question early, then expand with subheadings that cover related questions.
- Add original detail: examples, data you have collected, screenshots or first-hand experience.
- Link to related posts and relevant service pages, and link back to the post from older articles.
- Use a short, readable URL and descriptive alt text on images.
- Show the author and a published or updated date.
Organising a blog
Planning posts around topic clusters works better than publishing random articles. A central pillar page covers a broad subject, and supporting posts cover narrower questions, all linked together. Keep categories few and meaningful, and consider noindexing thin tag archives that add no value.
Common mistakes
- Writing about topics nobody searches for, or that have nothing to do with the business.
- Publishing many short, similar posts that compete with each other.
- Never updating old posts, leading to content decay.
- Leaving posts as dead ends with no internal links.
- Publishing unedited AI drafts that add nothing new.
Measuring results
Look at impressions, clicks and average position per post in Search Console. Review posts that have lost traffic every few months and decide whether to refresh, merge or remove them.
Do not judge posts on traffic alone. A post with modest visits can still be valuable if it earns links, ranks for questions your customers ask before buying, or sends readers on to a service page. Set up conversion tracking so you can see which posts lead to enquiries, sign-ups or sales, then write more content on the topics that perform. Posts that get no impressions after several months are worth reviewing: the topic may lack demand, the intent may be wrong, or another page on your site may already cover it better.
