LinkedIn Top Content Topic Map

LinkedIn sorts top posts into 40 categories, 805 subcategories and about 16,000 topics. This map puts all of them in one place, so you can see where your next post fits before you write it.

How to use the map

Click a category to open its subcategories, and click a subcategory to see its topics. If you’d rather not browse, type a keyword into the search box instead. Search highlights every topic that contains your word.

Why it matters

Every topic on Top Content has a page showing the posts LinkedIn rated best on that subject. A few of my older posts ended up on those pages, and each of them was written in the words of a topic LinkedIn already had. My working theory is that a post LinkedIn can match to a topic is easier for it to promote. A post on a subject the map doesn’t cover has no page to land on. Most of my posts about customer service software fall into that gap. Among 16,000 topics, Zendesk and helpdesks don’t appear once.

How I use it

Before I publish, I pick the subcategory a post belongs to and make sure the hook and first two paragraphs use its words. For me that’s usually Utilizing AI in Customer Support or Measuring Customer Experience ROI. When a post fits nothing, I choose on purpose. Either I reframe it toward the closest topic, or I publish it as it is and accept a smaller reach, because those posts are often the ones my future clients read. Once a month I tag my content calendar to see whether one subcategory takes over.

What the map can’t tell you

LinkedIn doesn’t publish how it picks Top Content posts, so treat the map as a strong hint that you test yourself. To check whether LinkedIn’s view of you is changing, download your Inferred Credibility Scores file before you start and again a month later.

I recheck these tables and publish new research on customer service software every month. It goes out on LinkedIn first.Follow on LinkedInKateryna Babenko
