How to Add Content Marketing as a Service to Your Web Design Agency

A web design agency can add content marketing without building a full writing team. You can hire in-house, use AI with strong human review or work with a content partner. The right model depends on your client demand, margins, internal skills and the level of oversight you can provide. From there, the key is to price the service properly, choose a reliable production process and start with an offer your agency can deliver consistently.

  • Choose a delivery model that fits your workload and internal capacity
  • Price the writing, briefing, editing and client management involved
  • Know what to look for if you outsource content production
  • Start with a practical offer and introduce it naturally to existing clients

You build beautiful websites. The client is happy at launch. Then six months later, the site has the same placeholder blog posts, half the service pages are thin, and the client wonders why their website is not generating leads.

This is the empty website problem, and every web design agency knows some version of it. You hand over a polished product, but without enough useful content, the website has less to work with. The client gets frustrated, and the value of the project becomes harder to see.

Content marketing can help solve that problem while creating an ongoing service for your agency. Here is how to add it without hiring a full team of writers or pretending to be something you are not.

The Business Case and Why Content Is Your Best Upsell

Web design is a project-based business. You build the site, you invoice, you move on. The client might come back for a redesign in three years, or they might not.

Content marketing is different because the need can continue after launch. Monthly articles, service page updates and campaign landing pages can all recur. Agencies that offer content alongside web design may see three practical benefits.

  1. Higher project values. Adding strategy and written content increases the scope of the project. How much it increases the value depends on the number of pages, research required and the level of review.
  2. Recurring revenue. Monthly content retainers provide predictable income between project launches.
  3. Better client outcomes. Websites with regular content generate more traffic and leads. Happy clients refer more work.

The objection most agency owners have is “We are not writers.” That is fine. You do not need to be.

Three Models for Offering Content

Model 1: Hire In-House Writers

Best for: Agencies with 10+ staff and consistent content demand.

Hiring a content writer or content manager gives you full control over quality and output. But it comes with fixed costs including salary, super, leave and training. If content demand drops, the employment cost remains.

Typical cost: $60,000-$80,000 per year for an experienced content writer in Australia. You need to consistently sell enough content to cover that cost plus margin.

The risk: If you lose two or three content clients, you still have the salary expense.

Model 2: Use AI Tools In-House

Best for: Agencies that want to test the market before committing.

AI writing tools (ChatGPT, Jasper, Copy.ai) can produce first drafts quickly. Some agencies use them to offer a basic content service at low margins.

The reality: AI tools produce draft-quality content, not publication-quality. Someone on your team still needs to do the following.

  • Research the client’s industry and competitors
  • Brief the AI with specific instructions
  • Edit the output for accuracy, tone, and brand voice
  • Optimise for SEO
  • Review for industry-specific compliance, especially for healthcare and finance

When you add up the time your team spends on briefing, editing, and quality control, the “cheap” AI content is not as cheap as it looks. And if the quality is inconsistent, it damages your agency’s reputation with the client.

Model 3: Partner With a Content Team

Best for: Agencies of any size that want to offer content without building a team.

A content partner handles the research, writing, and quality control. You white-label the output under your agency brand or present it as a collaborative service. You set the margin.

Advantages:

  • No fixed content-production salary because you pay for the work you actually commission
  • Quality and consistency are the partner’s problem, not yours
  • You can scale up or down based on client demand
  • You focus on what you do best while the content is handled by people who do that best

The risk: Choosing a bad partner. More on that in a moment.

How to Price Content Services

There are two common pricing models:

Markup Model

You buy content from a partner or freelancer at their price and add your margin. If a blog post costs you $150, you sell it for $250-350. Your margin covers account management, client communication, and quality oversight.

Pros: Simple to implement, clear margins.

Cons: Clients may compare your prices to direct content providers.

Bundled Model

You include content in your web design packages or monthly retainers. Instead of selling individual articles as separate line items, you might offer a monthly growth retainer that combines maintenance, content and reporting.

Pros: Higher perceived value, harder for clients to compare line items, stickier relationships.

Cons: Requires more planning and consistent delivery.

Our recommendation: Start with the bundled model. It positions content as part of a complete service, not an optional add-on.

What to Look for in a Content Partner

If you go the partnership route, here is what matters:

  • Research depth. The partner should research the client’s industry, competitors, and audience before writing. Content without research is filler.
  • Consistency. You need reliable quality and reliable turnaround. One good post followed by three mediocre ones damages your client relationship.
  • White-label capability. The content should feel like it came from your agency, not from an obvious third party.
  • Industry awareness. If you serve healthcare or financial services clients, the content needs to be accurate and appropriate for those sectors. This is not the same as cheap offshore content.
  • Communication. You need a partner who responds, takes feedback, and adjusts. Not one who delivers and disappears.

Red flags:

  • Prices that seem too good to be true ($30 per blog post is not going to be good content)
  • No samples or trial process
  • Offshore teams marketed as “Australian”
  • No revision process or quality guarantee
  • They cannot explain their research process

How to Position Content to Existing Clients

You already have clients with websites you built. Here is how to introduce content as a service without making it sound like a generic upsell.

The website review approach. Offer a free 15-minute review of the client’s key pages. Point out where service information is thin, outdated or missing, and compare that with the questions customers are likely to ask. The goal is to identify useful improvements, not simply prove that the website needs more blog posts.

The “your website is working, but it could work harder” conversation. Frame content not as fixing something broken but as unlocking potential. “Your website looks great and works well technically. The missing piece is content that brings people to it.”

The competitor comparison. Show the client what competitors are publishing, but focus on usefulness rather than volume. A competitor with more articles is not automatically performing better. Look at whether their content answers important questions or covers services your client’s website barely explains.

Start small. Do not pitch a 12-month content retainer on the first conversation. Offer a trial: “Let us write 3 blog posts for you over the next 6 weeks. If they perform, we can talk about an ongoing arrangement.”

The Minimum Viable Content Offering

You do not need a full content department on day one. Start with this:

  1. Add content to new website proposals. Include 5-10 pages of written content in every website quote. This solves the empty website problem at launch.
  2. Offer a post-launch content pack. After the website goes live, review the highest-priority pages and questions, then plan a small number of useful updates or articles.
  3. Build a referral arrangement. If you are not ready to offer content under your own brand, refer clients to a content partner and negotiate a referral fee or discount for future projects.

The point is to start somewhere. A website with thin or missing service information has less chance to explain the client’s value clearly, and that can reflect on the project even when your agency did not write the copy.
