• Focus first on pages with existing organic traffic or conversion value; those pages yield the fastest ROI.

• Keep alt tags concise and specific: 5 to 15 words is a practical range. Describe the image as a user who cannot see it would need to know.
• Include the main page topic or a natural keyword when it matches the image. Avoid keyword stuffing or generic phrases like image or photo.
• For purely decorative images, use empty alt attributes to avoid noise for screen readers.

• Ensure alt text complements the page headline and body text rather than repeating them verbatim.
• For product pages, include model, color, or distinguishing features that customers search for.
• For blog posts, link alt tag phrasing to the article's target phrase to strengthen topical relevance.

• For large catalogs, adopt templates: ProductType Model Color | Brand. This keeps alt tags consistent and SEO-friendly.
• Combine templated fields with contextual additions when necessary, for example special editions or unique angles.
• Document the pattern so content editors and developers apply it consistently across CMS updates.

• Ensure images are crawlable: avoid blocking images with robots.txt or disallow rules.
• Serve images with proper MIME types and verify they load without heavy client-side rendering that hides alt attributes.
• Use Layzr.ai's technical seo focus within an AI website audit to flag issues that prevent image indexing. Reference: Layzr.ai AI website audit

• Surround images with relevant captions and nearby text. Search engines evaluate the surrounding copy when interpreting images.
• Use descriptive file names that echo the alt text and on-page topic for an additional signal.
• Implement structured data when images represent products or recipes to provide explicit context for search engines.

• Prioritize clear descriptions for functional images like buttons and charts so screen reader users gain the same value.
• Accessibility improvements often align with better SEO because they increase clarity and user satisfaction.

• Track image-driven queries, impressions, and clicks in search console to measure alt tag work.
• For pages targeted in a Layzr.ai website audit, compare pre and post-implementation results on organic traffic and image search referrals.

Common pitfalls and how to avoid them

• Generic alt text: phrases like "product image" add no value. Replace with specific descriptors.
• Over-optimization: stuffing keywords harms readability and may be ignored by search engines.
• Inconsistent patterns: inconsistent alt tags across similar pages dilute the on-page signal. Use templates and CMS rules to enforce consistency.
