Generic Image Filenames: SEO Impact and Best Practices

Generic image filenames like "IMG_1234.jpg" or "photo1.png" are missed opportunities for SEO. Descriptive, keyword-rich filenames can help search engines understand your images and improve your overall search visibility.

What Are Generic Filenames?

Generic filenames are non-descriptive names often automatically assigned by cameras or basic uploads. Here are some examples:

Why Are Generic Filenames a Problem?

Generic filenames affect your website in several ways:

1. SEO Impact

   • Lost keyword opportunities
   • Reduced image search visibility
   • Weaker content signals
   • Poor contextual relevance

2. Content Organization

   • Difficult asset management
   • Poor searchability
   • Confusing media libraries
   • Inefficient workflows

3. User Experience

   • Less accessible content
   • Reduced context
   • Poor file organization
   • Limited understanding

How to Fix Generic Filenames

1. Audit Your Images

First, identify generic filenames:

// Function to detect generic filenames
function findGenericFilenames() {
  const images = document.querySelectorAll('img');
  const genericPatterns = /^(img_|dsc_|photo|image|picture)\d*\.(jpg|jpeg|png|gif)$/i;
  
  return Array.from(images).filter(img => {
    const filename = img.src.split('/').pop();
    return genericPatterns.test(filename);
  });
}

2. Implement Descriptive Names

Filename Structure:

// Format: primary-keyword-secondary-keyword.extension
