Content marketing: a guide to marketing with content

What is content marketing?

The Content Marketing Institute defines content marketing as a strategic marketing approach. It consists of creating and distributing valuable, relevant and consistent content. The goal: attract and retain a clearly defined audience, then drive profitable action (Content Marketing Institute definition).

The difference with advertising lies in the relationship. Advertising buys attention for as long as it runs. Content earns it, and keeps working as long as it stays useful. A well-made guide attracts readers for years; a campaign stops when its budget does.

Content marketing guarantees nothing, though. According to the Content Marketing Institute’s annual study, fewer than a third of B2B marketers consider their content strategy very effective.

Content marketing, inbound marketing and SEO: what are the differences?

The three notions overlap without being the same. Inbound marketing is an acquisition method: it attracts prospects instead of reaching out to them. Content marketing is its engine. But it also serves customer loyalty, recruitment or awareness. SEO, for its part, makes content findable on search engines.

Notion	Question it answers	Scope
Content marketing	What content to produce, for whom, and how to distribute it?	Editorial strategy, formats, distribution, measurement
Inbound marketing	How to bring in prospects and convert them?	Content, forms, nurturing, CRM
Content SEO	How does this content rank on Google?	Keywords, search intent, markup, internal linking
Brand content	What story does the brand tell?	Branded content, often emotional, often video

An example helps draw the line. A company publishes a guide and offers it in exchange for an email address. It then sends a series of messages until a sales meeting is booked. That is inbound. The same company publishes tutorials to help its customers make better use of its product. That is content marketing, with no acquisition funnel.

On this site, optimizing content for search is covered in SEO content and semantics. The writing itself falls under SEO writing. This page covers the strategy: why produce, what, for whom and with what return.

How do you build a content strategy?

A content strategy fits in a few pages, as long as it answers the right questions in the right order. Among B2B marketers who rate their strategy moderately effective or less, 42% cite a lack of clear goals. It is the most frequent reason, ahead of a lack of connection with the customer journey (39%), according to the same study.

1. Goals: awareness, leads, sales, loyalty or recruitment. Keep one or two, with figures and deadlines.
2. Audience: its questions, its objections, its vocabulary and the stages of its buying decision. A marketing persona formalizes this portrait.
3. Audit of existing content: what attracts, what converts, what is outdated or duplicated.
4. Editorial territories: three to five topics where the brand is legitimate and can say something new.
5. Formats and pace: chosen according to the real production resources.
6. Production: calendar, roles, in-house experts to interview, approval process.
7. Distribution: a plan for each piece of content, written before it is produced.
8. Measurement: compare the results with the goals from step 1, then adjust topics and formats.

A content strategy is often summed up in three pillars: the audience, the editorial line and measured distribution. To turn this summary into a concrete, step-by-step plan, see our page on how to build a content strategy.

The content strategy follows from the brand’s positioning. If the promise is not clear, the content rarely will be. So the work happens upstream, in branding and digital strategy.

Which content formats should you choose?

The right format is the one your audience consumes and that you can produce properly. Each format has a role in the journey.

Format	Main role	Stage of the journey
Blog post, guide	Answer a question, be found on search engines	Discovery
Video	Demonstrate, put a face on it, explain quickly	Discovery, consideration
White paper, e-book	Go deeper into a topic, collect contacts	Consideration
Study, barometer	Bring original data, get cited	Discovery, authority
Webinar	Interact live, qualify prospects	Consideration
Customer case study	Prove by example	Decision
Newsletter	Stay in touch, bring people back	Loyalty
Podcast	Build a long relationship with a loyal audience	Awareness, loyalty

Content published by your customers (reviews, photos, videos) is a family of its own: see our UGC guide.

Three skills each have their own page: copywriting to write copy that gets people to act, storytelling to tell the brand’s story, and the lead magnet to turn a reader into a contact.

Among the B2B marketers surveyed by the Content Marketing Institute, four formats come out on top. Video is rated the most effective (58%), ahead of case studies (53%). White papers and research reports follow (45% each). These figures describe self-reported perceptions, not a measure of performance. They point to leads worth testing, not a rule.

Content based on your own data has a lasting advantage. A study, a test or a case report with figures cannot be copied exactly by a competitor. It also gives the media and AI search engines a reason to cite you.

Finally, balance evergreen content and topical content. The first kind (guides, definitions, methods) attracts readers for years if it is kept up to date. The second (reaction to an announcement, a trend) creates a spike of attention, then fades. A healthy editorial line puts most of its resources into evergreen content.

How do you distribute and repurpose your content?

Publishing is not enough. Each piece of content needs a distribution plan across three types of channels: owned, earned and paid. Owned channels are your website and your newsletter. Earned channels come from shares, citations and press coverage. Paid channels are advertising.

In the Content Marketing Institute study, three channels dominate among B2B marketers. Organic social media comes first (89%), ahead of the website blog (84%) and newsletters (71%).

• on social media, adapt each piece of content to the platform’s format instead of posting a link;
• by email, send content to the people who asked for it;
• internally, give the sales team and customer service the content that answers their objections;
• in advertising, promote the content that has already proven its appeal organically.

Repurposing multiplies the value of an in-depth piece. One study can produce an article, a series of posts, a short video, a webinar and a newsletter. Also update existing content. An updated guide is often worth more than a new article on the same topic.

What do Google and AI search engines expect from content?

In its guide Creating helpful, reliable, people-first content, Google suggests evaluating each piece of content with three questions: who created it, how, and why. The author’s identity should be obvious. Signed content helps readers judge experience and expertise.

Volume is not a strategy. Google’s spam policies target the creation of many pages with the main purpose of manipulating rankings. They specifically mention generative AI tools used without adding value for users.

AI is not banned, though. Google’s guidance on AI-generated content asks you to aim for accuracy, quality and relevance. The requirement applies above all to automatically generated content.

Brand content and sponsored content: what are the rules?

Brand content and content marketing overlap without being the same thing: definition, formats and examples are detailed in our page on brand content. One rule still applies to both when content is paid for.

Content paid for by a brand and published by a third party remains a commercial communication. The third party can be a media outlet, a creator or a partner website. In France, the ARPP recommendation on identification, amended on May 21, 2025, sets a simple principle. A commercial communication must be easy to identify as such, whatever its format. The advertiser must also be recognizable.

In practice, this means three things. Display a clear label (“sponsored content”, “in partnership with”). Make the brand name visible. Do not disguise the content as independent information. This framework also protects the credibility of your non-sponsored content.

How do you measure content effectiveness?

Measurement is the weak spot of content marketing. In the Content Marketing Institute study, 56% of B2B marketers struggle to attribute a return on investment to content. The same share find it hard to track the customer journey. So choose the metrics according to the goal.

Goal	Metrics	Tool
Visibility	Search impressions and clicks, organic traffic, citations	Search Console, analytics tool
Engagement	Engaged sessions, engagement time, reading to the end	Google Analytics 4
Leads	Downloads, sign-ups, requests coming from a piece of content	Analytics tool, CRM
Sales	Content viewed before purchase, influenced revenue	CRM, attribution
Loyalty	Newsletter opens and clicks, return visits to the site	Email marketing tool, analytics tool

In Google Analytics 4, an engaged session meets one of three conditions. It lasts longer than 10 seconds, includes a key event or has at least two page views. The engagement rate is the share of these sessions (Google Analytics Help). Setting up tracking is detailed in our web analytics pillar page.

Complement the figures with qualitative signals. Does a prospect mention an article in a meeting? Do sales reps send a piece of content to their customers? Has a question disappeared from customer service? These signs often tell you better than a dashboard whether the content is doing its job.
