How to Create and Optimize Alt Text for Images to Improve SEO
When it comes to optimizing your website for search engines, many website owners overlook a simple yet powerful factor: alt text for images.
Alt text, or alternative text, serves as a description for an image, helping search engines understand what the image is about. It’s not just useful for SEO, but also for accessibility, ensuring that visually impaired users can understand the content of your site.
In this blog post, we’ll walk you through the importance of alt text, how to create and optimize it, and the best practices to follow for improving both your SEO rankings and user experience.
What is Alt Text and Why is It Important?
Alt text is a short description added to an image’s HTML tag that tells both users and search engines what the image depicts.
Here are a few reasons why it’s important:
1. SEO Benefits : Alt text helps search engines index images properly, improving your website’s visibility in image search results. Well-optimized alt text with relevant keywords can contribute to higher rankings for both images and web pages.
2. Accessibility: For visually impaired users, screen readers rely on alt text to describe images. Alt text ensures that your website is accessible to all users, regardless of disabilities, which can enhance user engagement and satisfaction.
3. Context for Search Engines: Google can’t "see" images the way humans do, so it uses alt text to understand the context of the image. Proper alt text ensures that search engines can better index your content and display it in relevant search results.
How to Write Effective Alt Text for Images :
Writing effective alt text is both an art and a science. You want to describe the image clearly and succinctly while incorporating relevant keywords. Here’s how to do it:
Describe the Image Accurately
Alt text should accurately describe what the image is about. Keep it simple and to the point. For example:- Poor Alt Text: “Image1”
- Good Alt Text: “Golden retriever playing with a ball in the park.”
Incorporate Relevant Keywords
Just like with other on-page SEO elements, use keywords in your alt text, but avoid keyword stuffing. Your goal is to make the description natural while still including relevant search terms. For example, if your blog post is about dog breeds, an image of a golden retriever might include alt text like: “Golden retriever dog breed playing fetch outdoors.”Keep It Short and Concise
While it’s important to be descriptive, alt text should generally be 125 characters or less. This is because screen readers usually cut off after 125 characters, and search engines prefer short, focused descriptions. A good rule of thumb is to aim for a concise yet informative description.Use Hyphens, Not Underscores
If you’re describing an image file name, use hyphens to separate words, as Google can better interpret them. For example:- Good:
golden-retriever-playing-fetch.jpg - Bad:
golden_retriever_playing_fetch.jpg
- Good:
Avoid Keyword Stuffing
Don’t overload your alt text with keywords. Write it as naturally as possible. If the image doesn’t fit naturally with the content of your page, consider removing it rather than forcing a keyword into the alt text.
Best Practices for Optimizing Alt Text for SEO :
Now that you know how to write alt text effectively, let’s go over some best practices for optimizing it:
Use Alt Text for All Images
Every image on your website should have alt text. This includes logos, banners, product images, and decorative images. For purely decorative images, you can use an empty alt attribute (alt=""), which tells screen readers to ignore it.Be Descriptive but Not Redundant
Don’t repeat the same description for every image. Each image should have unique alt text that reflects its content. For example, if you have multiple product images, each should describe the specific item shown, such as “Red leather handbag with gold accents” or “Close-up of men’s watch with stainless steel band.”Optimize for Context
Alt text should not only describe the image but also consider its context within the content. For example, if your blog post is about eco-friendly products, an image of a solar panel should have alt text like: “Eco-friendly solar panel installed on a roof.”Add Alt Text for Social Media Images
If you're sharing your images on social media platforms like Facebook or Twitter, ensure that alt text is included. Social media platforms like Twitter use alt text for images to improve accessibility for users with visual impairments.
Tools to Help You Optimize Alt Text :
If you’re managing a lot of images, writing alt text for every single one might feel like a daunting task. Fortunately, there are tools and plugins that can help automate and streamline the process:
- Yoast SEO: If you're using WordPress, Yoast SEO is a popular plugin that helps with on-page SEO, including alt text optimization. It provides suggestions for improving your image SEO.

Conclusion :
Alt text is a small but impactful element that can boost your website’s SEO performance while improving accessibility. By following the tips and best practices we’ve discussed, you can ensure that your images are indexed properly by search engines, making your site more visible and user-friendly.
Make sure to review your website regularly to check that all images have accurate, concise, and keyword-optimized alt text. With this simple SEO tweak, you’ll be well on your way to improving your site’s overall performance and accessibility.
