Structuring a blog post for SEO: length, E-E-A-T and keyword coverage

How long does a blog post need to be to rank?

Length is not a ranking factor, but an indicator. Google assesses whether a page fully satisfies search intent ^[1]. An article that does this is almost never 400 words long, and rarely 5.000 words long either. A useful rule of thumb: look at what ranks in the top 10 and cover the same breadth of topics without adding filler.

What matters is the information density of each paragraph. If you can remove a paragraph without losing any information, it was filler, and filler reduces dwell time.

What content belongs in every article?

Regardless of the topic, articles that rank follow a recurring structure:

1. A short answer at the top. Three to five sentences that directly answer the question in the title. This is precisely the block that ChatGPT, Perplexity and Google AI Overviews prefer to cite.
2. One H2 per subquestion, phrased as a question. This covers “People also ask".
3. At least one table with real figures or criteria. Tables win featured snippets.
4. At least one ordered list for processes or criteria.
5. A practical example from your own work, not from other blogs.
6. An FAQ at the end with six to ten questions, marked up with FAQ schema.
7. One clear next step, not three competing CTAs.

What are E-E-A-T signals and how do you incorporate them?

E-E-A-T stands for Experience, Expertise, Authoritativeness and Trust and comes from Google's Quality Rater Guidelines ^[2]. It is not a direct ranking factor, but an assessment framework that Google approximates through many individual signals. For an individual blog post, this means providing evidence that the writer has actually done the work they describe.

Experience: the difference almost everyone leaves out

Experience is the newest of the four criteria and the most valuable for agencies. It does not ask “Do you know this?", but “Have you done this yourself?". In practical terms, include:

• A real project with a name, starting point and outcome, linked to the case study.
• Figures from your own work rather than third-party studies, clearly identified as your own experience.
• Screenshots from real tools, proposals or analyses, not stock libraries.
• Honest limitations: when does your approach not work?

Why E-E-A-T has become more important since AI answers arrived

Language models need sources they can cite. An article that provides a specific figure, a named originator and a date is cited more often in AI Overviews and chat responses than content that makes the same point vaguely. In practice, this means writing sentences that can be quoted word for word without needing surrounding context.

How many keywords does a blog post need?

An article serves one search intent and therefore one focus keyword. Everything else is a variation, not an additional target. If you put two focus keywords into one article, both compete for the same page and neither wins. This is the most common mistake on company blogs.

A realistic keyword distribution per article

Semantic terms are words that inevitably appear when someone genuinely understands the subject. For “structuring a blog post for SEO", these might include search intent, snippet, internal linking, indexing and schema markup. You do not need to place them deliberately; you just need not to avoid them.

How do you cover a keyword fully?

1. Determine search intent. Informational, commercial or transactional? The top 10 will tell you in thirty seconds.
2. Read the SERP structure. Which H2s do the first five results use? Which “People also ask" questions does Google show? That is your outline.
3. Find the gap. What is missing from all ten results? Usually: specific figures, a real example or an honest limitation.
4. Write the outline before the article. One H2 per subquestion, no duplication.
5. Check after writing. Does the text answer every question from step 2 clearly and in an easy-to-find place?

Keyword density: the short answer

There is no target value. Google has worked semantically rather than through term frequency for years ^[3]. In practice: place the focus keyword in structurally important positions (title, short answer, one H2, slug, one alt text), then use it as often as feels natural. If you notice a word appearing too often as you read, it is appearing too often.

Which technical details also matter?

The best content is useless if the page delivers it poorly. We check these points for every article we publish:

• Server-side rendering. The content must be in the HTML, not loaded later via JavaScript. Otherwise, many AI crawlers see nothing.
• Exactly one H1, followed by a clean H2/H3 hierarchy with no skipped levels.
• Article and FAQPage schema, plus breadcrumbs. Generate the FAQ schema automatically from the FAQ field, not manually.
• Meta title under 60, description under 160 characters, with the focus keyword at the start.
• Images in WebP format with descriptive alt text and defined dimensions to prevent layout shifts.
• Internal links: two to four per article, with descriptive anchor text, plus a link back from the pillar page.
• Publication and update dates visible on the frontend and in the schema.

How do you get the article indexed?

Published does not mean indexed. Without actively submitting it, Google can take weeks to find a new post, especially on newer domains. That is why this step should be a fixed part of your workflow:

1. Publish the article and check the live URL in your browser (status 200, content visible in the source code).
2. Open URL Inspection in Google Search Console and paste in the full URL.
3. Click Test live URL and check whether the page is reported as indexable.
4. Click Request indexing. It usually takes hours to a few days after that.
5. After two weeks, check the “Pages" report to confirm that the URL has actually been indexed.
6. Check the sitemap: the article must appear in sitemap.xml, otherwise the crawler will not find it automatically on its next pass.

Which layout fits which search intent?

The same text does not work in every format. Someone asking about costs wants a table, not prose. Someone comparing options wants criteria side by side. That is why we decide on the layout before writing the first sentence.

How do you write paragraphs that can be cited?

Language models and featured snippets extract paragraphs, not articles. A citable paragraph meets three conditions: it answers a question fully, it works without the preceding paragraph, and it contains at least one specific detail. In practice: the first sentence gives the answer, the second the figure or condition, and the third the limitation. Everything after that adds depth.

Practical example: BxC Security, from relaunch to content structure

We rebuilt the website for BxC Security using exactly the sequence described here: first clarify which search intent each page serves, then define the structure and layout, then create the copy and imagery. The starting point was a site that said a lot about the company and little about the questions prospective customers bring with them.

The implementation: a clear page hierarchy with exactly one H1 per page, service content presented as standalone answers rather than a list, visible contact options and a technical setup that delivers text in the HTML rather than loading it later via JavaScript. Applied to the blog, this means each article gets a question as its title, a short answer and a layout that matches the intent.

How do you keep an article up to date?

Publishing an article is half the work. Here is what to schedule afterwards:

1. After four weeks, review the search queries in the performance report. Is the article ranking for the intended search intent or a different one?
2. After three months, check its position. Reworking content is most worthwhile between positions 11 and 20, because the jump to page one is shortest.
3. With every update, check figures, years and sources, and visibly change the update date.
4. Add new secondary keywords, when Search Console shows queries that the text does not yet clearly answer.
5. Add internal links, whenever a new article on a related topic is published.

Conclusion: structure beats word count

An SEO-optimised blog post is not longer content, but better-organised content. It fully answers one search intent, supports its claims with first-hand experience and genuine sources, naturally covers one focus keyword and related terms, and is delivered through a sound technical setup. Work consistently across these four areas and you do not need tricks.
