5-Step Correction Methodology
Facing a catalog of hundreds or thousands of products, the order of corrections is crucial to maximize your time ROI. Here is the proven method from Lexiik experts:
- 1Identify blocking errors (🔴)
Filter the dashboard to display only critical errors that prevent proper indexing.
- 2Prioritize best-sellers
Sort by generated revenue or number of views. Optimize the products that drive revenue first.
- 3Fix in batches of 50 products
Never modify 1,000 listings at once. Google prefers gradual changes.
- 4Measure impact after 2-3 weeks
Wait for Google's re-crawl before judging the effectiveness of your corrections.
- 5Iterate and optimize the rest of the catalog
Once best-sellers are optimized, gradually extend to the full catalog.

Fixing Structure & Tag Errors
1. Missing or Inadequate Titles (Title Tag)
The title is the most important SEO element of a page. Here is how to create optimal titles:
The magic product title formula
Example:
Nike Air Zoom Pegasus 40 Running Shoes | Responsive Cushioning - Free Shipping
58 characters | Keyword at the beginning | Call-to-action
The golden rules:
- 50-60 characters maximum (beyond that, Google truncates)
- Main keyword at the beginning of the title for more weight
- Each product must have a unique title
- Avoid filler words (the, a, of, to) at the beginning of the title
Premium Feature
Lexiik AI automatically generates optimized titles following this formula, by analyzing the best-sellers in your industry.

The meta description directly influences your CTR (click-through rate) in Google results. A good description can increase your CTR by 20-30%.
Structure of a high-performing meta description
Example: "Nike Air Zoom Pegasus 40 men's shoes: responsive ZoomX cushioning, optimal support, maximum breathability. Ideal for marathons and intensive training. Free shipping over $50!"
157 characters | Keyword present | Clear CTA
Meta description checklist:
- 150-160 characters (neither too short nor truncated)
- Main keyword naturally included
- Unique for each product (no copy-pasting)
- Include an urgency or value element (promo, free shipping, limited stock)
3. H1 Tags: One and Optimized
The H1 is the main visible title on your product page. It should be different from the Title (which appears in Google) but complementary.

Eliminating Duplicate Content
Duplicate content is the most common error in e-commerce and the one with the greatest negative impact on your SEO.
1. Detecting Duplicate Descriptions
Lexiik automatically identifies identical or very similar descriptions (>70% similarity). You will see in the dashboard:
- Groups of similar products: E.g. "25 products share this description"
- Similarity rate: Percentage of identical text between two listings
- Duplicate source: Internal (between your products) or external (supplier description)
2. Making Each Description Unique
You have 3 options to fix duplicate content:
Automatic generation of unique descriptions while preserving technical info but varying the vocabulary.
1 credit/product - Batch processing of 100
For your premium or highly technical products, manually write unique descriptions of 250-400 words.
Estimated time: 15-20 min/product
Hire a Lexiik-certified SEO writer to optimize your entire catalog.
Average rate: $8-15/product depending on complexity
Warning
3. Managing Product Variants
Selling the same t-shirt in 5 colors? Each variant must have a different description:
- Main variant: Full description (300 words)
- Secondary variants: Reuse the main description adding 2-3 sentences specific to the color/size
- Canonical tags: Point all variants to the main variant to consolidate "SEO juice"
Optimizing Images
1. Adding Descriptive ALT Attributes
ALTs are essential for Google Images, which can represent 20-30% of your organic traffic in e-commerce (especially fashion, home decor, beauty).
Anatomy of an optimized ALT
Generic ALT:
alt="image-product-123.jpg"ALT too short:
alt="Nike shoes"Optimal ALT:
alt="Nike Air Zoom Pegasus 40 black running shoes side profile view on white background"Product type - Brand - Model - Color - Camera angle
Rules for ALTs:
- 60-125 characters (neither too short nor a novel)
- Precisely describe what the image shows
- Vary ALTs between different photos of the same product (front, profile, detail, context)
- Naturally integrate the main keyword
Premium Feature
2. Reducing Image Weight
Images that are too heavy degrade your Core Web Vitals and penalize your search ranking. Target: <150 KB per product image.
- 1Resize to the right dimensions
1200x1200px max for a product listing (no need for 4000px)
- 2Convert to modern format
WebP or AVIF (50-70% savings vs JPEG/PNG)
- 3Compress intelligently
Quality 80-85% (invisible to the eye but significant weight savings)
- 4Lazy loading
Load images only when they become visible
Good to know
- WebP/AVIF conversion based on browser
- Automatic resizing (responsive)
- Smart compression

Improving Performance & Core Web Vitals
1. Reducing LCP (Largest Contentful Paint)
LCP measures the time before the main content is displayed. On a product page, this is typically the main image.
Corrective actions:
- Optimize the hero image: <150 KB, WebP format, exact dimensions (no CSS resizing)
- Preload the main image: <link rel="preload" href="main-image.webp" as="image">
- Fast hosting: CDN or server with good TTFB (<200ms)
- Reduce JavaScript: Avoid blocking scripts before image display
LCP Scale
2. Stabilizing CLS (Cumulative Layout Shift)
CLS measures visual instability. If your images or elements "jump" during loading, Google penalizes this.
Solutions:
- Specify width and height on all images
- Reserve space for banners and advertisements
- Avoid injecting content above the viewport after loading
- Use font-display: swap for web fonts
