Complete Guide on Image SEO – Importance of Alt Tags

Images are a powerful tool for grabbing attention and enhancing your website’s content. But did you know that images can also play a role in your website’s SEO? That’s where alt tags come in. They might seem like a small detail, but alt tags are a crucial part of image SEO and can have a big impact on your website’s success.

What are Alt Tags?

Alt tags, also known as alternative text, are hidden descriptions embedded within your website’s image code. They act like captions for your images, but they aren’t actually displayed on the page itself. Instead, alt text serves two main purposes:

Helping people who can’t see the image: For visually impaired visitors who rely on screen readers, alt text gets read aloud, describing the image and its content.

Informing search engines: Search engines use alt text along with other factors to understand what your images are about. This helps them rank your images in image search results and can even improve your website’s ranking for relevant keywords.

Adding Alt Text:

Including alt text is a simple process. The actual code will vary depending on the platform you use to build your website, but the basic syntax is the same:

HTML Code for Alt Tag

<img src=”image-file.jpg” alt=”Your descriptive text here”>

• <img> :This is the code that tells the browser to display an image.
  
• src: This attribute specifies the file path of the image you want to display.
  
• alt: This attribute holds the alternative text description for your image. This is where you’ll enter your descriptive text.

Alt Text Example:

Let’s say you have an image on your website of a delicious chocolate chip cookie. Here’s an example of how you might use the alt tag:

HTML

<img src=”chocolate-chip-cookie.jpg” alt=”Freshly baked chocolate chip cookie on a cooling rack”>

This alt text clearly describes the image for both users who rely on screen readers and search engines.

Benefits of Alt Tags :

While alt tags might seem like a minor detail, they offer a surprising range of benefits for your website. Here’s why including alt text is a smart SEO and accessibility practice:

1. Improved Search Engine Ranking:

Unlike humans, search engines rely on textual information to understand the content of images. Well-written alt text that includes relevant keywords can help search engines index your images and potentially improve your website’s ranking for those keywords. This can lead to more organic traffic from image search results.

2. Increased Accessibility for All Users:

Not everyone can experience your website visually. People with visual impairments often rely on screen readers to convert website content into audio descriptions. Without alt text, screen readers might simply announce “image” or “graphic,” leaving users with little understanding of the image’s content. Clear and informative alt text ensures everyone has access to the full meaning of your website’s content.

3. Enhanced User Experience:

Images can sometimes take a while to load, especially for users with slow internet connections. In these cases, alt text provides a temporary description of the image while it loads. This prevents users from seeing a broken image icon and keeps them engaged with your content. Additionally, clear alt text can improve the overall user experience by providing additional context and information about your images.

4. Better Brand Representation:

Thoughtful alt text allows you to control the narrative around your images. By including relevant keywords and descriptions, you can ensure your brand message is communicated effectively, even for users who can’t see the image itself.

In summary, alt tags are a win-win for both SEO and accessibility. They help search engines understand your content, improve the experience for all users, and ultimately contribute to a stronger online presence for your website.

Crafting Effective Alt Text :

Now that you understand the importance of alt tags, let’s dive into how to write effective ones. Important points to keep in mind:

1. Be Specific and Descriptive:

Your alt text should accurately capture the essence of the image. Instead of generic descriptions like “image1.jpg” or “picture of food,” aim for clear and concise language that describes what the viewer would see in the image.

For example, instead of:

alt=”food”
Use something more specific like:

alt=”Delicious chocolate birthday cake decorated with sprinkles.”

2.Include Relevant Keywords (Naturally):

Keywords can be helpful for SEO, but they shouldn’t overpower the natural flow of your alt text. Focus on describing the image accurately, and if relevant keywords fit naturally within that description, feel free to include them.

For instance, if the image is about a clicking selfie, you could use:

alt=”Woman with a red hat taking a selfie with her husband and son.”

3. Keep it Concise (Around 125 Characters):

Search engines tend to truncate long alt text descriptions, so it’s best to keep them concise and to the point. Aim for around 125 characters or less to ensure your entire message gets displayed.

4. Start Your Alt Text Descriptions Strong :

Screen readers will already announce that it’s an image, so there’s no need to waste valuable characters with phrases like “Image of” or “Picture of.” Get straight to the descriptive details.

5.Write for Everyone:

Avoid using overly technical language or jargon that might not be understood by everyone. Write your alt text in a clear and simple way that can be easily understood by a broad audience.

Examples:

Here are some examples to illustrate the difference between good and bad alt text:

Bad:

alt=”boat” (too vague)
alt=”beach picture” (generic)
alt=”person using laptop at desk” (descriptive, but keyword stuffed)

Good:

alt=”Red kayak on a calm lake surrounded by mountains” (specific and descriptive)
alt=”Couple building a sandcastle on the beach with their son and daughter”
alt=”Young adult engrossed in studying at a desk with a laptop open and textbooks surrounding them.” (descriptive and informative)

By following these tips, you can craft effective alt text that benefits both SEO and accessibility. Remember, your goal is to create clear and concise descriptions that accurately represent the content of your images.

Incorporating alt tags might seem like a small task, but it can have a significant impact on your website’s success. By providing clear and informative alt text, you’re not only improving your website’s SEO but also making it more accessible to everyone.
