Bulk optimization allows you to fix hundreds of products simultaneously, without manual intervention. This feature transforms weeks of work into just a few minutes of automated processing.

What is bulk optimization?
Bulk optimization is a feature that allows you to apply SEO corrections to a set of products in a single operation. Instead of processing each product listing individually, you select the items concerned and Lexiik automatically applies the recommended optimizations.
Types of optimizations available in bulk
Lexiik can automatically apply the following optimizations to multiple products:
- Meta descriptions: AI generation of unique and optimized descriptions (150-160 characters)
- ALT tags: Computer vision analysis and automatic generation of alternative text
- SEO titles (title tags): Rewriting with inclusion of main keywords (50-60 characters)
- Product descriptions: Semantic enrichment with complete lexical field (300-500 words)
- Canonical URLs: Fixing duplication errors and normalization
- Open Graph tags: Optimization for social sharing (Facebook, LinkedIn, Twitter)
- Structured data: Automatic injection of schema.org Product with price, availability, and reviews
Recommendation
How does bulk work?
Bulk optimization is based on three automated steps:
1. Product selection
From your Lexiik dashboard, you can filter products according to several criteria:
- By SEO score: Target products with a score below 60/100
- By error type: All products without a meta description, for example
- By category: Optimize an entire collection in one click
- By traffic: Prioritize products with the most organic visitors
- By revenue generated: Focus on items with high conversion potential
You can manually select products (individual checkbox) or use automatic selection via advanced filters. The simultaneous processing limit depends on your plan:
- Pro Plan: 100 products per operation
- Expert Plan: 500 products per operation
- Enterprise Plan: Unlimited (asynchronous processing)
2. Optimization configuration
Before launching the operation, you configure the optimization settings:
- Tone of Voice: Professional, casual, luxury, technical, etc.
- Priority keywords: List of terms to include in the generated descriptions
- Text length: Short (100-200 words), Medium (300-500 words), or Long (600-800 words)
- Target language: French, English, German, Italian, Spanish, Portuguese, Polish
- Advanced options: Include prices, promotional mentions, USP (Unique Selling Points)
Expert Feature
3. Execution and real-time tracking
Once the optimization is launched, Lexiik processes the products in the background. You receive a push notification (and an email if enabled) when processing is complete. The dashboard displays a real-time progress bar:
- Products processed: 47 / 100
- Credits consumed: 235 / 1,000
- Estimated time remaining: ~3 minutes
- Errors encountered: 2 failed products (detailed log available)
At the end of processing, Lexiik generates a downloadable optimization report in PDF, listing all changes applied product by product.
Use cases and real-world scenarios
Scenario 1: New collection launch
You have just imported 200 new products to your store. Rather than manually writing each listing, you use bulk optimization:
- Initial import via the Bridge module (automatic synchronization)
- Select the 200 products in Lexiik
- Configure the "Modern luxury" tone of voice with strategic keywords
- Launch the optimization (duration: 8 minutes for 200 products)
- Manually validate a sample of 10 listings
- Publish to production via secure rollback
Result: 200 optimized product listings in under 15 minutes, compared to 3 to 4 days of manual writing.
Scenario 2: Critical SEO error correction
After an SEO audit, Lexiik detects 150 products without a meta description (severity: "Critical"). You use the "Critical errors" filter to isolate these products and launch a targeted optimization on meta descriptions only.
Measurable impact: +37% average CTR in SERPs after 3 weeks, according to an internal study on 50 e-commerce stores.
Scenario 3: International expansion
You want to translate your catalog of 500 products into German and Spanish. Lexiik AI automatically generates localized descriptions (not a simple literal translation, but a cultural adaptation) for each target language.

Best practices and recommendations
Before launching the optimization
- Test on a sample: Start with 10-20 products to validate the tone of voice
- Check your AI credits: View your balance in the credits guide
- Create a snapshot: The Time Machine lets you undo changes in one click
- Analyze current KPIs: Note your current SEO score to measure post-optimization impact
During the optimization
- Do not close the window: Processing continues in the background, but you lose the real-time view
- Monitor errors: If more than 5% of products fail, stop the process and check the logs
- Avoid duplicates: Do not launch two simultaneous optimizations on the same products
After the optimization
- Sample validation: Manually check 5-10% of optimized listings
- KPI monitoring: Track CTR and conversion rate evolution for 2-3 weeks
- Google indexing: Submit modified URLs via Google Search Console to accelerate crawling
- Download the report: Keep a record of changes for your internal documentation

ROI and time savings
Time savings calculation
Comparison between manual writing and automated optimization:
| Task | Manual | Lexiik Bulk | Gain |
|---|---|---|---|
| Meta description (100 products) | ~8 hours | ~5 minutes | 96x faster |
| ALT tags (200 images) | ~6 hours | ~3 minutes | 120x faster |
| Long descriptions (50 products) | ~20 hours | ~10 minutes | 120x faster |
ROI calculation
Based on an average web copywriter salary of €35/h, optimizing 100 products represents:
- Manual cost: 8h × €35 = €280
- Lexiik cost: 100 products × 5 credits = 500 credits ≈ €15 (Expert plan)
- Net savings: €265 per bulk operation
For an average e-commerce site that optimizes 300 products per month, the annual savings amount to €9,540, not counting the velocity gain (faster go-live = earlier ROI).
Premium Feature
Measurable SEO impact
According to an internal study conducted on 200 stores using Lexiik between January and December 2025:
- +42% organic traffic within 30 days following a bulk optimization of 100+ products
- +28% average CTR in SERPs thanks to optimized meta descriptions
- +18% conversion rate thanks to enriched product descriptions (complete lexical field)
- -35% bounce rate on optimized product pages (more relevant content)

Limitations and alternatives
When NOT to use bulk?
- High-end luxury products: Opt for bespoke manual writing for high-margin items (>€500)
- Complex technical products: AI may lack accuracy on very detailed specifications (requires human validation)
- Products with a unique USP: If your differentiation relies on an exclusive argument, write manually
- Niche markets: AI may lack specialized vocabulary (e.g., medical equipment, rare industrial parts)
Hybrid mode: Bulk + Manual validation
The best approach often involves combining both methods:
- Bulk optimization to generate a first version (5 minutes)
- Manual validation on 10% of products to check consistency (30 minutes)
- Manual adjustments on strategic products only (1-2 hours)
This hybrid workflow divides processing time by 10 while maintaining human quality control on critical elements.
