Introduction
Long-term content strategy is an approach commonly used by businesses and marketing professionals to improve their search engine rankings. It involves producing in-depth, detailed content that offers great value to readers.
Why can long-form content improve your ranking?
Creating long-form content can considerably improve your website's ranking on search engines such as Google. This is because Google measures the relevance and quality of content. In other words, detailed, quality articles that cover topics comprehensively are more likely to appear at the top of search results, as they are considered to offer exceptional value to readers.

The correlation between content depth and algorithmic relevance signals
When Google rolled out the "Hummingbird" update in 2013, SEOs finally understood that the engine was no longer content to match a keyword to a page; it was trying to interpret the intent behind the query. A long-form article naturally meets this requirement, as it offers more context, lexical co-occurrences and potential responses. The richer the text, the more it provides the algorithm with enough to build a coherent semantic graph, which translates into improved positioning.
. For example, the Investopedia site has climbed to the top of the SERPs for complex financial terms, not by fragmenting its explanations, but by offering glossaries of several thousand words that dissect the rules, players and formulas. On Ahrefs, these pages reveal hundreds of 'ranked' keywords - proof that an exhaustive treatment of a subject multiplies the number of organic entry points.
How the E-A-T concept is strengthened by a long article
The acronym E-A-T (Expertise, Authoritativeness, Trustworthiness) has become central since the 2018 Medical Update. Google's Quality Raters value the demonstration of expertise, proof of authority and the perception of trustworthiness. However, from an accounting point of view, it is difficult to cram studies, scientific citations and links to government sources into a 500-word post. The long format offers the necessary latitude to include: author biographies, methodological paragraphs, research boxes, data graphs and historical comparisons. Doctors at the Mayo Clinic, for example, publish 2,000- to 4,000-word disease briefs that include bibliographies, disclaimers and post-diagnostic instructions. Not only do these signals improve E-A-T, they also increase the probability of obtaining the "zero index" badge (featured snippet), because Google detects highly reliable content that can be associated with sensitive medical queries.
Case study: Healthline's organic domination
Healthline is a perfect example of the synergy between length and credibility. Having brought in-house a review committee made up of doctors, the platform has rewritten thousands of articles so that they are systematically longer than 2,500 words. It also added "Medically reviewed by" sections and clickable bibliographies. The result: according to Semrush, the site has grown from 29 million monthly organic visitors in 2019 to more than 80 million in 2023. This growth can be explained not only by
The log analyses show an increase in the crawl budget allocated by Googlebot, proof that the engine considers the content important enough to return to it frequently. In its annual report, Healthline reveals that 67 % of new pages ranked top 3 contain more than 3,000 words and 15 external links to peer-reviewed studies.
Behavioural metrics: session duration, scroll depth and SERP return rate
One of the theories that appeals to modern SEOs is that Google uses anonymised user signals, such as pogosticking, to reassess the relevance of a result. Long, well-structured content naturally extends session length and scroll depth, which reduces negative signals. The New York Times, for example, found that a long-read exceeding 4,000 words generated 12 % more reading time than a standard article, even after correcting the data for the subject matter. By introducing interactive inserts - quizzes, timelines and videos - the newspaper reduced the SERP return rate from 18 % to 9 %. These figures show that enriching an article beyond the plain text creates a captivating experience, which the algorithm can interpret as high user satisfaction.
Positioning the long tail: capturing satellite queries using semantic coverage
The principle of the long tail, theorised by Chris Anderson, stipulates that all the small, low-competition queries represent potential traffic greater than the cumulative top keywords. A long-form article can address all these micro-queries in the same space. Backlinko popularised this approach with its 12,000-word "complete guide to on-page SEO": the page now ranks for over 1,900 different queries, including phrases such as "SEO H2 title" or "keyword density 2024". This volume of words means that synonyms, named entities and adjacent content (UX, Core Web Vitals, schema.org) can be inserted naturally without resorting to keyword stuffing, improving overall relevance while avoiding penalties for over-optimisation.
Example: the HubSpot model and its "Pillar Pages
HubSpot introduced the "pillar page" concept in 2017 to dominate entire themes such as "inbound marketing" or "sales enablement . Each pillar, of around 6,000 words, is linked to around thirty satellite articles that delve deeper into sub-topics: A/B testing, lead scoring, marketing automation, etc. This siloed architecture reinforces contextual relevance and ensures that internal link juice circulates efficiently. Databox has measured that HubSpot's pillar pages generate 7 times more backlinks on average than short articles, demonstrating that exhaustive content becomes a natural reference to cite, particularly in presentations or academic research.
Synergy with internal networks and thematic clusters
Long-form content is an ideal anchor point for distributing internal PageRank. By inserting contextual links to more specialised articles, we reduce the number of clicks needed to reach each resource ("flat architecture" principle), while at the same time signalling the page hierarchy to crawlers. Patagonia uses this strategy on its environmental blog: each 5,000-word main feature on, for example, melting glaciers, links to field studies, interviews and recycled product sheets, creating an authoritative cluster. Screaming Frog's logs show that deep URLs receive 28 % more bot visits when they are linked from long content compared with links from short files, proof of the importance of meshing.
Extended storytelling: building audience loyalty and strengthening the brand
Long-form doesn't just serve SEO; it also builds an editorial identity. Patagonia, once again, integrates climber testimonials, photo archives and call-to-actions to ecological petitions into the same editorial piece. This multi-channel narrative increases emotional engagement, which is reflected in the average number of social shares, often correlated with organic visibility. A BuzzSumo study of 100 million articles showed that posts exceeding 2,000 words received 56 % more Facebook shares than posts of 500 words. The snowball effect is twofold: SEO benefits from off-page signals (social backlinks, mentions) and the brand consolidates its in-depth storytelling.
Hybrid formats: guides, case studies and white papers
When Salesforce publishes its "State of Marketing Report", it's more than just an article; it's a 60-page document, available in PDF and long HTML versions. By integrating embeddable infographics and chapter summaries, the company multiplies the possibilities for incoming links. Numerous B2B blogs cite these statistics, giving Salesforce a constant flow of quality backlinks. Converting a white paper into an interactive guide is therefore a profitable editorial strategy: you benefit from the authority of the search format while capturing the organic traffic that a static PDF does not generate. Rich Snippet data (HowTo, FAQ) can then be added, offering enhanced SERP visibility without any reduction in length.
Optimising the user experience for texts of over 3,000 words
Length does not have to mean cognitive fatigue. Surround your content with an anchored summary, clear H2/H3 headings, "TL;DR" blocks and inset quotes. Medium has found that the completion rate drops drastically after 7 minutes of continuous reading. To counter this, Wired magazine intersperses images every 350 words, a practice that Nielsen Norman Group considers ideal for rekindling attention. Add accordion tables (expand/collapse) for side sections, guaranteeing stable Core Web Vitals. The Page Experience algorithm prioritises responsiveness (INP), so long-form content must load quickly: lazy-loading of images, separation of critical CSS, external video hosting. Long-form content that loads slowly will lose its SEO advantage due to degraded UX signals.
Long drafting tools: IA, PAA and named entities
To cover a semantic field without gaps, several tools stand out: AnswerThePublic exposes the "People Also Ask" that Google suggests; InLinks breaks down the subject into entities, indicating those that an expert should mention. By combining this data with AI suggestions (ChatGPT, Jasper), the writer obtains a detailed plan that maximises relevance without unnecessary filler. The Washington Post uses an in-house algorithm, Heliograf, to spot subcontracted angles on a subject and inject explanatory paragraphs, ensuring smooth editorial revision for articles exceeding 5,000 words. Automate the search for scientific citations using the semantic scholar engine; you'll gain both depth and credibility, fuel for E-A-T.
Measuring impact: comparing KPIs before and after long-form content
Putting a 4,000-word article online without any metrics is like driving without a dashboard. Start by defining a benchmark: Search Console impressions, CTR, median positions, bounce rate, average time on page. After 30 days, compare. Buffer found that an "ultimate guide to social planning (3,500 words) has: +62 % impressions, +22 average positions, -18 % bounce rate and +70 % conversions to the free trial. Correlations show that brand traffic increases in parallel (Google Trends) - a sign that long-form contributes to overall brand awareness. Implement Scroll Depth events in Google Analytics 4 to measure attrition by section, optimising paragraphs that are too dry or smooth.
Risks and limits: cannibalisation, dilution and maintenance
Content that is too long can cannibalise your secondary pages if the same keywords appear on them. Let's regularly audit the Search Console to detect queries that switch from one URL to another; in this case, consider consolidation or the use of "nofollow" anchors. Another risk is the dilution of information. A 10,000-word page that drifts into a confused off-topic will lose trust and serendipity. Finally, editorial maintenance: technical guides (e.g. "Configuring Kubernetes") age quickly. To limit the cost of updating, Shopify has adopted a modular structure - each section is a reusable Markdown include. Updating the Stripe API no longer involves rewriting the entire file, just modifying the module concerned.
Roadmap: from subject research to multi-channel promotion
1) Research: identify a niche with a topic gap using Semrush or Keyword Insights.
2) Planning: create a semantic mind-map of sub-topics and assign them to H2/H3s.
3) Writing: apply the Pomodoro method to avoid fatigue. Insert studies, Datawrapper graphs and quotes from experts. Check that the density of named entities covers at least 85 % of the occurrences listed by InLinks.
4) Technical optimisation: add an anchored summary, reduce CSS, host images in AVIF.
5) Publication: use the FAQ, HowTo or Article schema to enrich the SERP.
6) Distribution: break up the content into LinkedIn microposts, Twitter threads and Instagram carousels. Convert it into a PDF gate to get e-mail leads.
7) Update: set a quarterly reminder to check data, broken links and regulatory developments (RGPD, ADA).
Strategic conclusion
Long-form content is not simply word inflation; it is an editorial infrastructure that simultaneously ticks the boxes of algorithmic relevance, brand authority, user engagement and backlink generation. Various organisations - Healthline, HubSpot, Salesforce, Patagonia - have proved this with concrete figures: tripled traffic, longer sessions, increased brand awareness. As long as you respect search intent, added value and UX, length becomes a competitive advantage, not a burden. In a landscape where automated text generation is trivialising short content, investing in masterpieces of 3,000 to 10,000 words is perhaps the best insurance against algorithmic obsolescence.
