Because the posts aren't optimized for Pinterest and therefore aren't Pinterest friendly or pinnable.
For quite a while I was guilty of this. I didn't think about others sharing my content on social media, especially Pinterest. So for several months, actually close to a year, my posts weren't optimized for Pinterest and no one pinned them. But after reading about the success other bloggers had on Pinterest and why they had that success I made some wholesale changes to my content.
Under no circumstances do I consider myself a expert on Pinterest. In fact I've only been using Pinterest for a short while now and am still working to figure it out. But while I'm not an expert I do have an understanding and appreciation of what makes a blog post Pinterest friendly.
1. Graphics or images sized for PinterestWhat makes a graphic or image pinnable is its size. Pretty much any article, study, or blog post about creating images for Pinterest says they should be vertical or portrait style and long. In fact the longer your image is the better chance it has of being repinned. Short and horizontal images don't stand out and get lost among the pins decreasing their chances of being repinned.
The solutionCreate at least one image for your post that is at least of 600x900px which is the recommended minimum size. I make all my graphics using the Canva Pinterest graphic template that is 725x1102px. The more room your pin takes up, the more likely it will get noticed, liked and saved.
You can also create really long images, such as collage images, that you hide in your posts. You can learn how in this post by Chole Danielle.
2. Attractive images or graphicsEven if the image is the right size for Pinterest, if it's not an attractive image or doesn't fit my image aesthetic I won't pin it. What makes an image unattractive for Pinterest is it's
- Too dark
- Blurry or fuzzy
- Out of focus
- Has too much text
The solutionUse better images which can be done in a variety of ways
- When taking your own images, use a lot of natural light
- Edit your images/and ore use image filters. I use the Adobe Lightroom and Photoshop apps to edit my images
- Use high resolution images so they don't pixelate when you increase the size, crop or edit them in any way
- Use free apps to add attractive text overlays. My favorite app for creating graphics and adding text overlays is Canva

3. Graphics/images with descriptionsDescriptions are a big part of what pulls your pins into searches on Pinterest. A description tells people what the content or blog post is about. It's also a place to encourage or entice people to click through to take in your content.
When I select an image from a blog post that I want to pin and there's no description I do one of two things 1) create my own, 2) don't pin it and leave the site. Because I'd rather spend time creating my own descriptions for Pinterest I tend to do two more often than one.
The solutionFill out the alt text for your post images. Pinterest pulls the alt text for their pin descriptions when you pin directly from your site. So when someone pins from your blog and your images don't have the alt text, that person has to come up with their own description. This could be a deterrent for them to pin from your site.
4. Easy to find share buttonIf I can't find an easy way to share a post to Pinterest I may copy the post url and pin the post that way. But more often than not, I just leave and don't pin the post. I didn't want this to happen when people visited my site resulting in me missing out on free exposure and traffic driving opportunities. So I incorporated a variety of ways for someone to share my blog post.
The solutionAdd share buttons to your blog that are easy to find and use. My site template has some social share buttons attached to each post. I also use free share buttons from SumoMe that show up on every page and post on my site. The SumoMe share buttons are easy to set up and can be customized to fit the look of your site. Also, I added the Pinterest save button that shows up as an overlay when you hover over any of my post images.
