In my experience, a common misperception of the evaluation of content quality is that its scope is limited to the correction of typos and grammatical errors. Correcting spelling and grammar only scratches the surface. To truly consider content quality, we need to examine its quality along several dimensions. Consequently, the content quality checklists that follow cover everything from usefulness to voice to accuracy.
- Usefulness & Relevance:
- Does the content meet user needs, goals, and interests?
- Does the content meet business goals?
- For how long will the content be useful? When should it expire? Has its usefulness already expired?
- Is the content timely and relevant?
- Clarity & Accuracy:
- Is the content understandable to customers?
- Is the content organized logically & coherently?
- Is the content correct?
- Does the content contain factual errors, typos, or grammatical errors?
- Do images, video, and audio meet technical standards, so they are clear?
- Influence & Engagement:
- Does the content use the most appropriate techniques to influence or engage customers?
- Does the content execute those techniques effectively?
- Does the content use too many or too few techniques for the context?
- Does the content include all of the information customers need or might want about a topic?
- Does the content include too much or too little information about a topic for the context?
- Voice & Style:
- Does the content consistently reflect the editorial or brand voice?
- Does its tone adjust appropriately to the context—for example, sales versus customer service?
- Does the content convey the appropriate editorial and brand qualities?
- Does the content seem to have a style? If so, does the content adhere to it consistently?
- Does the content read, look, or sound as though it’s professionally crafted?
- Usability & Findability:
- Is the content easy to scan or read?
- Is the content in a usable format, including headings, bulleted lists, tables, white space, or similar techniques, as appropriate to the content?
- Does the content have the appropriate metadata?
- Does the content follow search engine optimization (SEO) guidelines—such as using keywords—without sacrificing quality in other areas?
- Can customers find the content when searching using relevant keywords?
A Few Caveats
While I think these content quality checklists are a good place to start, it’s important to note several caveats relating to their scope and appropriate use.
- As for any heuristic evaluation or competitive analysis, the expertise of the person evaluating the content is as important as the heuristics he or she uses.
- An expert opinion is still an opinion. It is also important to consider other indicators of content quality such as Web metrics, usability testing, and customer feedback.
- These checklists do not entirely fit user-generated content or user assistance content. However, I think variations of these basic checklists might be useful for those contexts.
- These checklists certainly do not replace other important content strategy tools such as detailed content inventory and analysis.
Why Content Quality Matters
If you already care about content, you know instinctually that its quality matters. Personally, when I encounter bad content, my blood pressure starts to rise, and I feel an uncontrollable urge to fix it. However, not everyone instinctually cares about content quality. (If they did, bad content would not be so rampant.)
What if you have to convince people who are oblivious to content quality that they need to improve the quality of their content? Persuading them will require more than a heuristic evaluation or a competitive analysis. Fortunately, some experts have already made compelling cases for content quality, so you don’t have to start from scratch. You can build on their convincing arguments:
- Content is a strategic brand asset. If the purveyors of the brand or marketing are your audience, this argument will resonate. Content is a significant part of the brand experience, and we should treat it as such. Improving content adds luster to the brand. Kristina Halvorson and Joe Pulizzi make this case effectively. 
- Content is a major part of the user, or customer, experience. If those who are responsible for user experience or customer service are your audience, this argument will garner attention. Redish’s Letting Go of the Words can help you make this argument. Halvorson also makes a clear case that content is a user experience issue.  It’s not just some arbitrary substance that fills our designs.
Ensuring Content Quality: Beyond the Style Guide
Let’s say you’ve made a winning case for content quality and successfully improved its quality on a project. Inevitably, the question of maintaining the quality of content will next arise. I’ll now highlight a few ways of effectively maintaining content quality. This topic is rich and merits more discussion, but this list will at least help you move forward:
- testing content with users—Incorporate questions about content in your user interviews, focus groups, usability tests, and surveys. We don’t discuss testing of content enough, and I plan to discuss it more in upcoming columns.
- monitoring content metrics—Engagement is a metric that suits content well. For content that’s meant to support conversions, tracking whether conversions increase after improving content is important. For example, InterContinental Hotels Group conducted a pilot comparing their existing hotel content with improved content, which was professionally written and photographed. Everything else about the user experience was identical. With the improved hotel content, the increase in conversions was so significant it resulted in an immediate decision to improve all hotel content. 
- establishing governance—Have a group of stakeholders from across the company or organization meet regularly to oversee major content decisions.
- applying the publishing model to content—The publishing industry, for the most part, knows how to develop quality content—despite occasional disappointing efforts. (See Joe the Plumber as author.) Jeffrey MacIntyre articulates the publishing model well.  For major content efforts, a publishing structure and related tools—such as an editorial calendar—are a natural fit.
- incorporating content guides, standards, and tips into CMS workflows—I would love to see guidelines for content quality incorporated into CMS (Content Management System) workflows. Including some contextual Help or quality checklists would provide effective reminders, preventing the people who approve content from forgetting what the content guidelines are. Publishing guidelines in a hard-to-find document probably won’t help much in the day-to-day grind of content publishing.
- maintaining the metadata—I am not a metadata expert, but I know that, as the semantic Web progresses from dream to reality, metadata is becoming even more important to content quality. Rachel Lovinger demystifies metadata, noting important strategies and tools. 
- hiring employees, consultants, and agencies who care about content—Whether you need a lone content evangelist, an outside agency, or your own content team, hiring people who have an instinct for and expertise in content will go a long way toward preserving its quality.
