Frequently Asked Questions
What are image alt tags and why are they important?+
Alt tags (alternative text) describe images for search engines and screen readers. They're crucial for SEO (helping images rank in image search), accessibility (helping visually impaired users), and user experience (displaying when images fail to load). Missing or poor alt tags hurt both SEO and accessibility.
What makes a good image alt tag?+
Good alt tags are descriptive (explain what's in the image), concise (ideally 125 characters or less), include relevant keywords naturally (no stuffing), provide context for the page, and avoid phrases like 'image of' or 'picture of'. For decorative images, use empty alt tags (alt='') to tell screen readers to skip them.
How many images can I analyze at once?+
Our tool analyzes all images on a given URL automatically. Enter any webpage URL and we'll extract all images, check for missing alt tags, evaluate alt text quality, flag issues like keyword stuffing or missing attributes, and provide recommendations for each image.
What common image SEO mistakes does the tool detect?+
We detect: missing alt tags, empty or generic alt text ('image1.jpg'), keyword stuffing in alt tags, overly long descriptions (over 125 characters), decorative images with alt text, broken image links, and missing title attributes. Each issue includes specific recommendations for fixing it.
Should all images have alt tags?+
Content images (photos, diagrams, infographics) should have descriptive alt tags. Decorative images (borders, spacers, purely aesthetic elements) should have empty alt tags (alt='') to indicate they're not important for content understanding. Never leave the alt attribute completely missing.
How does image SEO affect search rankings?+
Properly optimized images improve SEO in multiple ways: images can rank in Google Image Search, alt text provides context for page content, good image SEO improves page load speed, accessibility improvements reduce bounce rate, and comprehensive alt text helps with semantic SEO and topical authority.
