Alt text, or alternative text, plays a pivotal role in both web accessibility and SEO. If you’ve ever wondered how to craft the perfect alt text or are searching for an alt text example to guide your efforts, you’re in the right place. This article dives into the essentials of writing effective alt text, showing you how to enhance your website’s user experience while giving your SEO a significant boost.
What Is Alt Text?
Alt text is a descriptive attribute added to an image’s HTML code. Its primary purpose is to describe the content of an image for visually impaired users and assistive technologies. Additionally, alt text provides search engines with information about an image, which helps with indexing and can improve your website’s visibility in search results.
Why Is Alt Text Important?
1. Improves Accessibility
Alt text allows visually impaired users to understand the content of images through screen readers, making your website more inclusive.
2. Boosts SEO
Search engines rely on alt text to understand images, which can improve your rankings and help your images appear in Google Image search results.
3. Acts as a Backup
If an image fails to load, the alt text will display, ensuring users still understand the content or context.
The Anatomy of Great Alt Text
When crafting alt text, keep these principles in mind:
- Be Descriptive: Clearly describe the image in detail.
- Use Keywords Sparingly: Include relevant keywords, but avoid keyword stuffing.
- Keep It Relevant: Ensure the alt text aligns with the surrounding content.
- Be Concise: Aim for 125 characters or less for clarity and screen reader compatibility.
Alt Text Example
Here are some practical alt text examples to guide you:
Example 1: Product Image
- Image: A red running shoe.
- Alt Text: “Red running shoe with breathable mesh design and white sole.”
Example 2: Blog Post Illustration
- Image: A person typing on a laptop with a coffee cup nearby.
- Alt Text: “Person typing on a laptop with a coffee cup on a wooden desk, representing productive work habits.”
Example 3: Infographic
- Image: A pie chart showing social media usage.
- Alt Text: “Pie chart illustrating social media usage in 2023, with 45% on Instagram, 30% on TikTok, and 25% on other platforms.”
Best Practices for Writing Alt Text
1. Avoid Starting with “Image of” or “Picture of”
Search engines and screen readers already recognize the element as an image, so there’s no need to state it again.
2. Incorporate Keywords Naturally
For SEO purposes, include keywords where relevant but avoid forced placement. For instance:
- Instead of: “Red running shoe for SEO keyword stuffing.”
- Use: “Red running shoe with breathable mesh for marathon runners.”
3. Focus on Context
Think about how the image supports the surrounding text and craft your alt text accordingly.
Common Mistakes to Avoid
1. Keyword Stuffing
Example: “SEO, alt text example, alt text for SEO, SEO keywords.”
Why It’s Wrong: This provides no real context and harms usability.
2. Vague Descriptions
Example: “Image of a shoe.”
Why It’s Wrong: It doesn’t provide enough detail for users or search engines.
3. Ignoring Decorative Images
For purely decorative images, use an empty alt attribute (alt=””) to ensure screen readers skip them.
Advanced Techniques for Alt Text Optimization
1. Leverage AI Tools
Tools like AltText.ai can analyze your images and suggest optimized alt text based on context, saving you time and ensuring consistency.
2. Analyze Competitors
Look at how top-ranking sites in your niche handle their alt text. Use tools like Ahrefs or SEMrush to review their image SEO strategies.
3. Regularly Audit Your Alt Text
Use SEO tools to identify missing or poorly written alt text and update them to align with current best practices.
How Alt Text Fits into Your SEO Strategy
Alt text is not just about accessibility; it’s a key part of on-page SEO. Including optimized alt text can:
- Increase your chances of appearing in Google Images.
