Key Takeaways

  • HubSpot COS (Content Optimization System) is HubSpot’s term for its CMS. Where a traditional CMS manages and publishes content, HubSpot COS is designed to optimize it for conversions, personalization, and inbound marketing from the ground up.
  • The four main advantages over a standard CMS are integrated SEO tools, personalization tokens tied to the CRM, membership-based content gating, and smart forms and CTAs that adapt to the visitor in real-time.
  • Compared to WordPress, HubSpot COS wins on marketing integration and requires no plugins for analytics, SEO, or automation. WordPress wins on market share, plugin ecosystem breadth, and flexibility for non-marketing use cases.
  • HubSpot COS development requires more than drag-and-drop familiarity. Custom templates, HubSpot API integrations, and module-level customization typically need a developer who holds HubSpot’s CMS design certification or has hands-on experience with HubL, HubSpot’s templating language.
  • Most businesses get the most out of HubSpot COS when a developer builds the initial template and module structure, then hands control to the marketing team for ongoing content creation and campaign management.

Anyone who spends a fair bit of time in the marketing world is probably familiar with acronyms for 'complex' marketing jargon like search engine optimization (SEO), content management system (CMS), or customer relationship management (CRM).

But what about a content optimization system (COS)? More specifically, what about HubSpot's COS?

While other acronyms have been popularized through technology like WordPress and Salesforce, HubSpot has its own terminology to define its utility.

Let’s look at what a COS is, how HubSpot employs the term, and why more and more fintech companies are adopting the technology.

If you need an experienced HubSpot developer with many years of experience in the field, who understands the unique complexities of the fintech industry, we can help.

What Is a COS?

A content optimization system (COS) is an exclusive facet of HubSpot. In one sense, it is an extension of a traditional CMS.

HubSpot calls itself an all-in-one inbound marketing tool because, in contrast to regular CMS software, it offers every element needed to market your blog and/or website.

Features such as marketing automation, email marketing, social media management, and a free CRM tool are included off the bat. Other CMS software relies on the user to add this as additional software, often in the form of plugins.

In other words, a COS is a CMS with a particular interest in driving leads and boosting your marketing efforts.

What Is HubSpot COS?

HubSpot COS and HubSpot CMS are more or less synonymous.

HubSpot CMS, officially called CMS Hub, has the capacity to power and grow your website. Developers can build custom themes to entice website visitors. They can also use the HubSpot App Marketplace to add functionality to their website and create apps with HubSpot APIs.

This allows websites to flourish without the need for a ton of plugins.

Business marketers have the freedom to rely on developers as much or as little as they want. And professional developers can empower them with a fully-fledged website.

Notable features of HubSpot CMS include its drag-and-drop editor, SEO recommendations, contact attribution reporting, multi-language content curation, and adaptive testing.

These features and a dozen more are equipped at setup, so you can worry about content optimization rather than configuration.

HubSpot COS makes it possible to publish content, track visitor behavior, and adjust your strategy all from one platform, something a traditional CMS requires multiple tools and plugins to replicate.

4 Advantages of HubSpot COS

Now that you know a bit more about HubSpot COS, let’s take a more detailed look at what it can offer.

A presentation slide titled "4 Advantages of HubSpot COS," listing SEO Tools, Personalization Tokens, Memberships, and Smart Forms.

1. SEO Tools

Search engine optimization (SEO) is pretty much always a hot topic for content writers, copywriters, businesses, marketers, and really just any individual or entity who wants to get organic attention on the web.

As more than 90% of web traffic goes to the first page of results, it's important to do what it takes to get your website noticed by web crawlers so it can get situated near the top.

HubSpot's SEO tools are integrated into every bit of your content. The software can point you to the domain and page that needs updating. You'll get actionable recommendations on how to improve SEO ranking in order of priority, showing which actions have the most and least impact.

An intentional content strategy also builds search authority. Luckily, HubSpot has a content strategy tool that will give you topic suggestions based on relevance, popularity, and competition.

You will get access to monthly search data as well.

From there, you can create clusters of web pages around these core topics. Using canonical URLs will help focus your strategy and lead to more organic traffic.

2. Personalization Tokens

In HubSpot, personalization tokens allow you to show personalized content based on the user. The idea is to add a sense of individualism by inserting names, job titles, and even custom objects into traditionally automated content.

Personalization tokens are correlated with the property values in your CRM.

A token can be a company, contact, office location, or subscription type. The properties associated with these tokens differ based on the specific token.

For example, a company has properties like industry and the company owner. An office location has properties like city and state. And a contact has properties like first and last name.

You can add personalized content to your emails, landing pages, newsletter sends, and website pages. Ultimately, this will increase engagement with your marketing campaigns and improve the overall user experience for each segment of your audience.

3. Memberships

Memberships are a unique feature of HubSpot that can target specific segments of your consumer base in order to grant them access to specialized content.

Using HubSpot lists, you can decide who is able to see certain sections of your website and tailor different content to these users.

A creative way to utilize this feature is by creating personalized membership pages and using dynamic content to your advantage. Some examples might be a dashboard of sorts featuring recent purchases, past attended events, or upcoming workshops.

You can choose to be inclusive to your whole consumer base or have exclusive content and leave website visitors wanting more. Both are excellent ways to expand your business growth.

4. Smart Content, Smart Forms & CTAs

Smart content is yet another way to personalize your website pages, landing pages, emails, CTAs, and forms.

Based on a set of characteristics, you can choose what call-to-action (CTA) a website viewer sees or how an interested party fills out a form.

Smart rules control what the viewer sees, and the following criteria can determine the customized CTA button that appears. This includes country, device type, referral source, preferred language, contact list membership, and lifecycle stage.

For forms, there are a variety of methods you can use to increase conversions.

You can give the user a shorter form if they're on a mobile device, change the language of the form depending on their location, or make more advanced questions depending on the lifecycle stage of the visitor.

What Is the Difference Between HubSpot COS and a Traditional CMS?

HubSpot has several competitors, ones that may call themselves a CMS and occasionally a CRM, fundamentally, but HubSpot COS is a different tool entirely.

A traditional CMS handles content creation and publishing. HubSpot COS, on the other hand, is designed to help businesses create, optimize, and personalize that content simultaneously, while measuring the impact through integrated marketing analytics.

HubSpot COS vs. WordPress

HubSpot's biggest competitor is WordPress. The competition is rooted in WordPress's popularity as the CMS platform has supported many individuals and businesses before CMS Hub ever existed.

Naturally, this means that their market shares are vastly different, with WordPress dominating at about 39.1% and HubSpot lagging along at 0.1%. However, when HubSpot is observed as a marketing tool alone, it dominates the industry with a 33.91% market share.

This is why HubSpot and WordPress need to be compared using factors other than popularity and rather on the merit each can offer. 

The more practical question to consider is which one your team actually needs.

While both platforms serve as a space to create and publish content, WordPress does just that, leaving users with the basics that they can build on top of using plugins.

HubSpot COS is designed for optimization, so the notion of getting conversions is built into the platform, as well as gaining insights into market performance.

It's worth breaking things down to understand some of these differences.

Blog

Blogging seems to be the greatest common factor between WordPress and HubSpot COS. 

WordPress was originally built for blogging but quickly evolved into a CMS. 

CMS Hub can do the same essential things as WordPress, but you don't need additional plugins or software to optimize your content, hence HubSpot's title as a COS.

Landing Pages

Creating a custom layout in WordPress may require the help of a developer, although the platform has many pre-made themes.

The same goes for HubSpot. Although they boast many mobile-optimized templates on their marketplace, most businesses should hire a developer to keep things original.

Website

WordPress is an easy way to create a website, and as you saw, many people utilize it for that reason. HubSpot COS does the same, but elements like testing or live chat are included from the start, unlike WordPress.

WordPress's flexibility comes through its plugin ecosystem, while HubSpot COS offers a more unified all-in-one platform where marketing, web design, and analytics connect without additional integration work.

SEO

Again, WordPress has no native functionality with SEO, although Yoast and RankMath are both popular plugins with SEO recommendations.

HubSpot COS doesn't need a plugin. SEO recommendations are an integral part of the software.

Analytics

Some editions of WordPress do include limited reporting, like page views, but most marketers will pay to use a separate tool and have a deeper analysis.

HubSpot COS is tied with a customer relationship management system, making marketing analytics an integral part of the puzzle.

Marketing Automation

WordPress requires third-party plugins or tools like Mailchimp or ActiveCampaign to run marketing automation.

Just like with SEO, HubSpot COS includes automation workflows natively, covering email sequences, lead nurturing, and CTA triggers without leaving the platform.

How To Create a Website on HubSpot COS

HubSpot COS takes out many of the technicalities usually involved in web development from scratch. The process is intuitive and simple, and you have a variety of tools at your disposal to make it even easier.

1. Make a Home Page

The very first page you should create is a landing page. This will be your home page, where users can navigate to other parts of your website. In the HubSpot portal, you can click 'Content', then 'Landing Pages'.

2. Use a Template

After setting up a landing page, you need to choose a template. This is very important as it will determine the overall style and layout for your website and therein your brand.

You can check out the HubSpot Marketplace and browse for templates you like. If you want more customization or need added control, you can hire a developer to make a customized template so you can aim for a more original website.

One of the greatest benefits we have seen here is that marketing teams can edit without touching code, so you don’t need a developer on hand for simple, day-to-day changes.

3. Edit Modules

Modules are objects on your landing page that you can create and edit, like text boxes, for instance.

We often see this used to convey brand messages or to help users navigate through the website.

4. Create Website Pages

Once your landing page is done, creating another page is as simple as going to a dropdown menu where you can click 'Create website page'.

Name the page, edit it, and add as many additional pages as you need.

The last step is, of course, to integrate social media. Once you have been up and running for some time, you can look at your analytics and write blog posts as needed.

HubSpot COS Development: What It Actually Involves

A skilled developer working in HubSpot COS typically works with HubL, as we have already mentioned.

They use HubSpot's proprietary templating language to build custom modules, flexible templates, and dynamic web content that a marketing team can then manage without technical knowledge.

Common HubSpot COS development tasks include:

  • Building custom templates from the ground up or adapting HubSpot Marketplace themes
  • Creating reusable modules that allow marketers to create and edit content without developer involvement
  • Integrating the HubSpot API with external tools, CRMs, or data sources
  • Setting up automation workflows tied to form submissions, page visits, and CTA interactions
  • Configuring smart content rules and personalization tokens connected to CRM properties
  • Implementing best practices for HubSpot COS SEO, including structured data and canonical URL configuration

Developers either have a portfolio that they can show you, or they have pursued formal credentials like HubSpot's CMS design certification, which covers the platform's architecture, HubL syntax, and module development in depth.

Is HubSpot COS Right for Your Business?

HubSpot COS for your business makes the most sense when marketing and web presence are closely tied, and your team wants to manage both from a single place.

We often recommend HubSpot if a company is trying to run active inbound marketing programs, they want to personalize content for different audience segments, and they'd rather pay for an all-in-one platform than manage a stack of integrated plugins.

Where HubSpot COS may not be the natural fit is if you just need an informational website and limited lead generation needs, if you are working with large enterprise teams with complex custom functionality requirements that a traditional CMS like WordPress would handle more flexibly, or organizations where the development team already has deep WordPress expertise and the marketing team works comfortably within it.

The cost is also a real consideration.

HubSpot COS sits at a higher price point than WordPress, which is open-source and free to host. For a business that will use HubSpot's marketing automation, CRM, and analytics features extensively, we have found that cost is often justified by consolidation.

How To Hire a Developer for HubSpot COS

Once you've decided what to do with HubSpot COS and have the budget to do it successfully, hiring developers is the way to go if you want a smooth launch for your website. Developers can come in one of three forms:

  • in-house
  • freelance
  • agency

In-house developers are employed by you and receive a salary. But if you only need developers for one project, full-time employees may be too much of a commitment.

Freelancers are, by definition, not committed, but they will work on your project if hired and paid reasonably. The thing is, you can't tell them how or when to do it.

Outsourcing agencies can be a convenient mix of both these forms. Developers from outsourcing agencies will be fully committed to your project until its completion.

Conclusion

HubSpot COS is an ecosystem that works within itself to provide you with the tools you need to amplify your online presence.

With it, you can design a user-tailored experience to attract and convert leads and measure your performance as this happens in real-time.

That said, a truly customized experience cannot be garnered with HubSpot COS alone.

To make your website stand out from the rest, you need highly experienced software engineers.

A team of developers who understand HubSpot COS development, HubL, and the platform's API can build the template and module foundation your marketing team needs to manage your site independently and improve conversions over time.
