# Write SEO product descriptions in bulk

One line per product in, a structured description out: a benefit-led paragraph, feature bullets and a meta description, as JSON columns ready for a product feed.

**Run it:** [Write SEO product descriptions in bulk on Apify](https://apify.com/fayoussef/bulk-llm-runner/examples/seo-product-descriptions-in-bulk?fpr=youssef&fp_sid=abe_ex_seo-product-descriptions-in-bulk)  
**Actor:** [Run GPT, Claude, DeepSeek... Prompts in Bulk (No API Key)](https://automationbyexperts.com/apify/bulk-llm-runner)  
**Pricing:** $0.002 per result

## What this task is for

The prompt asks for the same three pieces for every product, so the output lands in consistent columns instead of free prose you have to cut up by hand. That consistency is the whole point when a catalogue has hundreds of rows and the copy has to drop into a feed.

It runs on GPT, Claude or Gemini without an OpenAI, Anthropic or Google key of your own, because the actor carries the model access and bills per result. Swap the product lines for your own catalogue and the word counts in the prompt for your template.

## The input this task runs with

```json
{
  "prompts": [
    "Product: Patagonia Nano Puff insulated jacket. Write a 60 word benefit led description, 4 feature bullets, and a 155 character meta description.",
    "Product: Hydro Flask 32oz wide mouth water bottle. Write a 60 word benefit led description, 4 feature bullets, and a 155 character meta description.",
    "Product: Anker 737 140W USB-C power bank. Write a 60 word benefit led description, 4 feature bullets, and a 155 character meta description.",
    "Product: Brooks Ghost 16 neutral running shoe. Write a 60 word benefit led description, 4 feature bullets, and a 155 character meta description."
  ],
  "system_prompt": "You are a senior ecommerce SEO copywriter. Write in plain, concrete language. Never invent specifications you were not given. Return the keys description, bullets and meta_description.",
  "model": "anthropic/claude-haiku-4.5",
  "response_format": "json_object"
}
```
