AI SEO Writer for Shopify — Ordnance | Claude + Semrush product description generator

Most "AI SEO" tools are GPT-3.5 with a Shopify API key. Ours pulls live Search Console keyword data, runs Semrush keyword research, and generates with Claude Opus 4.7. Cost: ~$0.05 per SKU. Quality: dramatically better than the alternatives.

How it works

Live Google Search Console data

Real queries driving traffic to each product, with impressions, clicks, position. Powers untargeted-keyword detection.

Semrush keyword research

Related, phrase-match, and question keywords for the target term. Used to populate FAQ sections + body H2s.

Claude Opus 4.7

The strongest model for long-form generation. Stable system prompts hit Anthropic's prompt cache for ~10x cost savings on repeated calls.

Three outputs per call

SEO title (60-70 chars), meta description (150-160 chars), body HTML (rendered + raw shown).

Push directly to Shopify

One click writes the title_tag, description_tag metafields + descriptionHtml. Updates existing products or creates new.

Bulk mode with budget caps

Generate SEO for an entire vendor catalog in the background. Set $ budget cap; we stop before exceeding it.

AI SEO writer FAQ

How much does it cost?

~$0.05 per SKU on Opus 4.7 with prompt caching active. Cheaper if you switch to Sonnet 4.6. Bulk jobs let you set a $ budget cap.

Do I need a Semrush subscription?

For maximum quality, yes — ~$140/mo Semrush Pro. The platform works without it (uses GSC data only) but Semrush adds 30%+ to keyword targeting quality.

Will this trip Google's "AI-generated content" filter?

No. Google's position is "AI-generated content is fine if it's helpful and human-reviewed". The output is reviewed-and-approved before push by default.
