My Changelog website is where I keep track of all my creative work online. It contains links to every article, newsletter edition, digital product, and project I create.

I built it in Jekyll, my static site generator of choice.

One of the first hurdles I had to navigate when building the site was how to display a stats page. This would summarize all my content under a few different parameters. I wanted to display counts of posts per categories as well as tags.

Here’s how I accomplished setting up a display of post counts per category and tag.


Site Structure

Let’s start with a summary of how things are set up on the Changelog site.

I have the following tags:

These serve as the main buckets or topics I talk about most often. My niche if you will.

Milestone is slightly different. It denotes various markers I want to celebrate like hitting 500 Twitter followers or growing my Medium following.

Then I have categories:

These denote the type of content I’ve created.

Here’s a screenshot of my stats page to show you the end result:

Stats Page

As you can see, each component shows the tag/category name and a count of the posts under that tag/category.

Each component also has a link to the relevant tag/category page to help with navigation.

I highly recommend you check out the live version of the site for more context: Changelog Stats


Display Post Count By Tag

This couldn’t be simpler. All you need to add is the following code:


{{ site.tags.Creation | size }}

Just replace Creation with the name of your tag. The only thing that could potentially trip you up here is misspelling the tag name so be sure to double-check that.


Display Post Count By Category

Post count by category is equally as easy to implement. Just use the following code:


{{ site.categories.Article | size }}

Again, be sure to double-check spelling here as this is what usually trips me up.


Display Post Count Of All Posts

If you want a count of all posts on your website, here’s the code:


{{ site.posts | size }}}

Super simple 👍


Count All Posts Minus A Specific Tag

Here’s a fun one that will hopefully be helpful to you.

On my homepage, there is a picture of me and underneath it is a level counter. I set this up to try and gamify my content creation. The higher the level, the more content I’ve created.

Stats Page

To accomplish this, I needed to count all posts except for milestone type posts (as these aren’t pieces of content I’ve created, they’re just events).

Here’s the pseudo-code: my current level = all posts - milestone posts. Then divide by 10 (this step is optional for you)

Here’s the code I used to make that happen:


 {% assign count_posts = site.posts | size %}

 {% assign milestone_posts = site.tags.Milestone | size %}

 {% assign total_posts = count_posts | minus: milestone_posts %}

 <span class="font-bold pl-2">Level {{ total_posts | divided_by: 10 }}</span>

Pretty cool right?

Just replace the “Milestone” tag with your own tag.

In your case, you may not need “divided_by: 10” as this was something I added in to determine the level to display.
