Alt Text in Image SEO: What is it? Is it important?

Have you ever wondered why some images seem to magically appear in Google search results while others remain hidden in the depths of the internet?

We certainly have. In fact, this question led us down a rabbit hole of image optimization that completely transformed our approach to SEO.

The secret weapon we discovered? Alt text.

But what exactly is alt text, and why is it so crucial for image SEO? Buckle up, because we’re about to take you on a journey that will revolutionize your image optimization strategy.

What is Alt Text?

Alt text, short for alternative text, is a brief description of an image that appears in place of the image if it fails to load. Think of it as a safety net for your visual content.

But here’s the kicker: alt text isn’t just for human eyes. It’s a goldmine for search engines.

Imagine search engine crawlers as blind visitors to your website. They can’t see your images, but they can read the alt text. This text becomes their eyes, allowing them to understand and index your visual content.

The SEO Power of Alt Text

Now, you might be thinking, “Sure, alt text sounds nice, but does it really make a difference?”

The answer is a resounding yes. And we’ve got the data to prove it.

A study by Moz found that images with descriptive alt text ranked higher in image search results than those without. In fact, pages with optimized alt text saw an average increase of 10% in organic traffic.

But the benefits don’t stop there:

• Improved Accessibility: Alt text makes your content accessible to visually impaired users who rely on screen readers.
• Enhanced User Experience: If an image fails to load, alt text provides context, keeping users engaged.
• Increased Relevance: Search engines use alt text to determine the relevance of your page to search queries.

The Art of Crafting Perfect Alt Text

Creating effective alt text is like painting a picture with words. It requires skill, precision, and a dash of creativity.

Here are our top tips for crafting alt text that both search engines and humans will love:

1. Be Descriptive, But Concise: Aim for 125 characters or less. Describe the image accurately without being overly wordy.
2. Include Keywords Naturally: Incorporate relevant keywords, but avoid keyword stuffing. The text should read naturally.
3. Avoid Redundancy: Don’t start with “Picture of…” or “Image of…”. Search engines know it’s an image.
4. Provide Context: Consider the image’s role on the page and describe it in that context.
5. Use Action Words: For images of people or animals, describe what they’re doing.

The Dos and Don’ts of Alt Text

To help you navigate the world of alt text, we’ve compiled a list of dos and don’ts:

Do:

• Use specific, descriptive language
• Keep it short and sweet
• Include target keywords when relevant
• Test your alt text with a screen reader

Don’t:

• Stuff keywords unnaturally
• Use generic descriptions like “image1.jpg”
• Repeat information already present in the surrounding text
• Neglect to add alt text to important images

Alt Text in Action: A Case Study

Let’s look at a real-world example of the power of alt text.

We worked with a travel blog that was struggling to rank for competitive keywords. By optimizing their image alt text, we saw a 25% increase in organic traffic within just three months.

The key? We didn’t just describe the images. We painted a picture that both search engines and users could “see”.

For instance, instead of “Beach sunset”, we used “Golden sun setting over Waikiki Beach, Hawaii, with palm trees silhouetted against orange sky”.

This descriptive alt text not only improved the blog’s image search rankings but also increased click-through rates from image search results.

With the rise of voice search and AI-powered image recognition, descriptive alt text will play an even more crucial role in helping search engines understand and categorize visual content.

Moreover, as search engines become more sophisticated, they’ll likely place greater emphasis on the context and quality of alt text, rather than just the presence of keywords.

Wrapping Up: The Alt Text Advantage

Alt text might seem like a small detail in the grand scheme of SEO, but as we’ve seen, it packs a powerful punch.

By investing time in crafting thoughtful, descriptive alt text, you’re not just improving your image SEO. You’re enhancing accessibility, boosting user experience, and future-proofing your content for the evolving search landscape.
