Why turn a blog post into Pins

A blog post only gets found if someone searches for it. A Pin gives the same post a second door. People use Pinterest to search for ideas and save them for later, and every Pin can link straight to your post.

The catch is volume. One Pin per post rarely does much. Different headlines and images reach different searches, so the usual approach is several Pins per post, spread out over time. That’s exactly the repetitive part AI handles well.

What a Pin needs

Pinterest’s own product specs set the basics for a standard image Pin:

One thing to notice: most blog images are wide. A 3:2 blog infographic won’t work as-is. Rebuild it as a tall image instead of shrinking it.

The workflow: one post, five Pins

1. Pick the angles. Paste your post into an AI chat and ask for five different reasons someone would click: a how-to, a checklist, a mistake to avoid, a question, a quick result.
2. Write the words. For each angle, get a short headline for the image, a Pin title that starts with the keyword, and a description in plain sentences.
3. Design. Put each headline on a 2:3 template. Keep one font and one color set so your Pins look like a set.
4. Check. Read every title and description against the post. Cut anything the post doesn’t actually say.
5. Publish or schedule. Post one now, spread the rest over the following weeks, each linking to the same post.

Step 4 is the one people skip. AI is happy to promise “10 free templates” when your post has one. A Pin that overpromises gets clicks once and loses trust.

The 4 tools compared

1. An AI chat: for the words

Any major AI chat can read your post and draft angles, titles, and descriptions. It’s the cheapest part of the workflow and the one that needs the most checking. Use the prompts below so it sticks to what your post says.

2. Canva: for the design

Canva has a large library of free, customizable Pinterest Pin templates already sized for Pinterest. Pick one template, make it yours once, and reuse it for every post so your Pins are recognizable.

3. Pinterest’s own bulk and RSS tools

Pinterest can do more on its own than most people realize. According to Pinterest Create, you can upload a CSV file to create up to 200 Pins at once, with titles, descriptions, links, and boards. You can also connect an RSS feed so Pinterest creates image Pins from new posts automatically, usually within 24 to 48 hours. RSS auto-publishing needs a business account and a claimed website, and both tools are desktop only.

If your blog runs on WordPress, it already has a feed. One downside: auto-created Pins use the images in your post, which are often wide. Designed Pins usually look better.

4. Metricool: one calendar for every channel

Metricool schedules posts across several social platforms from one calendar. The free plan allows up to 20 scheduled posts a month, and paid plans start at $20 a month billed annually. Its plan page doesn’t spell out Pinterest support on the free plan, so check that before you commit. Good fit if Pinterest is one of several channels.

Which route? Just starting and want zero cost: AI chat + Canva + Pinterest’s own scheduler. Lots of Pins at once: Pinterest’s CSV bulk upload. Running Pinterest plus Instagram or Threads: Metricool keeps them on one calendar. Publishing a lot and okay with plain Pins: RSS auto-publishing.

Copy-and-paste prompts

How to use these:

1. Copy your blog post text (or the key sections).
2. Run Prompt 1 to get five angles.
3. Pick the angles you like and run Prompt 2 for the words.
4. Check every line against your post.
5. Put the image headlines into your design template.

Tip: tell the AI your main keyword. Otherwise it’ll invent clever titles nobody searches for.

Here is my blog post: [paste text]
Main keyword: [keyword]

Give me 5 different Pinterest Pin angles for this post:
1. How-to
2. Checklist or list
3. Mistake to avoid
4. Question
5. Quick result or before/after

For each angle, write one line on why someone would click.
Only use ideas that are actually in my post. Do not promise anything the post doesn't contain.

For each angle below, write:
- Image headline: 8 words or fewer
- Pin title: under 100 characters, starting with the main keyword
- Description: 2 to 3 plain sentences, under 500 characters, including the keyword once

Angles: [paste the angles you chose]
Main keyword: [keyword]
Post URL: [url]

Rules: no hashtags, no clickbait, no claims that aren't in the post.

Example (fictional)

Everything here is made up for illustration.

A small baking blog has a post called “Sourdough Starter for Beginners.” Main keyword: sourdough starter. Prompt 1 returns five angles. The blogger keeps three:

The AI’s fourth title promised “a free printable schedule.” The post doesn’t have one, so it was cut. Three Pins, one Canva template, one link, spread over three weeks.

Quick checklist:
☐ Every Pin is 2:3.
☐ Every title starts with the keyword.
☐ Every claim is in the post.
☐ Every Pin links to the exact post.
☐ Pins share one template so they look like a set.
☐ Pins are spread out, not posted all at once.

FAQ

What size should a Pinterest Pin be?

Pinterest recommends a 2:3 ratio, or 1000 x 1500 pixels. Taller images may get cut off in feeds.

Can I create Pins automatically from my blog?

Yes. Pinterest can auto-create image Pins from your blog’s RSS feed if you have a business account and have claimed your website.

How many Pins should I make per blog post?

There’s no official number. Start with three to five different angles per post, spread out over a few weeks, and keep the ones that get clicks.

Is there a free way to do all of this?

Yes. A free AI chat, Canva’s free Pin templates, and Pinterest’s own scheduling and bulk tools cost nothing. Metricool also has a free plan with a monthly limit.
