How Important Is Alt Text For SEO? (And Why We Wouldn’t Skip It)
Alt text (alternative text), also known as “alt attributes” or “alt descriptions,” is a topic in SEO that often slides under the radar. Yet, it’s one of those cornerstone practices that could mean the difference between your content being accessible and understandable by search engines or not. Neglecting it is not an option if you aim for your website to climb SEO rankings. In this blog post, we delve into the importance of alt text for SEO and highlight reasons you shouldn’t skip it.
Understanding Alt Text: A Brief Overview
Before we proceed, let’s quickly define what alt text is for those unfamiliar. Alt text is the written copy that appears in place of an image on a webpage if the image fails to load on a user’s screen. This text helps screen-reading tools describe images to visually impaired readers and allows search engines to better crawl and rank your website.
1. Enhancing Accessibility
The core purpose of alt text is to provide a text alternative for search engines and users who can’t see the images on a webpage. For users with visual impairment, alt text is crucial as it is read aloud by screen readers in place of an image. By providing a clear and concise description, you ensure that all users, regardless of physical ability, have a consistent experience on your site.
2. Bolstering SEO
Search engines are increasingly sophisticated, but they still can’t “see” images the way a human does. They require text to understand the context of images. Alt text gives you the opportunity to include relevant keywords that can help your page rank higher for those terms.
3. Improving User Experience
If an image fails to load due to poor internet connection or server issues, the alt text ensures the message isn’t lost. Site visitors can still grasp the context provided by the accompanying image through the description given in the alt text, ensuring a better user experience.
4. Boosting Engagement and Retention
Descriptive alt text can spur curiosity or provide instruction, which could increase the time a user spends on your page. High engagement and low bounce rates signal to search engines that your content is valuable, subsequently improving your rank.
5. Serving as Anchor Text
When an image is linked, its alt text can function like anchor text for a text link. This could provide additional context for the linked page, which, again, is beneficial for SEO.
6. Enhancing Social Media Sharing
Alt text can also make sure the image is properly described when shared on social networks like Pinterest or Facebook, making the content more accessible and correctly interpreted by different platforms’ algorithms.
Crafting the Perfect Alt Text: Best Practices
Now, knowing the weightage of alt text, here are some actionable best practices for creating alt text that not only boosts SEO but also enriches user experience:
Use Precise, Descriptive Language
Your alt text should accurately describe what is being shown in the image. Just as you would like Google to understand the rest of your content, ensure your alt text tells a story about your image.
Keep It Concise
While detail is good, brevity is better. Aim for around 125 characters or less, as most screen readers cut off alt text at this point.
Include Keywords Appropriately
Incorporating your target keywords can help improve SEO, but don’t force them in. The primary purpose of alt text should be to describe the image, not to keyword stuff.
Avoid Redundancy
There’s no need to state “image of” or “graphic of,” as the screen reader will already announce the presence of an image. Dive straight into the description.
Reflect the Intent
If the image includes text that is crucial to understanding the content, make sure to include it in your alt text. If the image is conveying a particular action or emotion that is important for context, describe it.
Be Context-Relevant
A picture can mean many things depending on its context. Ensure your alt description relates to the content of the page the image is on.
Remember Decorative Images
If an image is purely decorative and adds no additional information, it’s still best practice to include an alt attribute, but it can be left empty. This tells screen readers to skip over the image.
The SEO Impact of Skipping Alt Text
Ignoring alt text means missing out on a valuable opportunity to improve your site’s accessibility and search rankings. Yet, it’s surprising how often alt text is overlooked. This not only impacts the experience for users with disabilities but also affects engagement and SEO rankings negatively.
Final Thoughts
Alt text may seem like just another SEO checkbox, but its role in web accessibility and search engine indexing is significant. In the world of SEO, every detail matters, and alt text provides an opportunity to make your images work harder for your website’s performance. As search engines aim to deliver the best user experience, they favor websites that do the same. So, don’t skip the alt text; it could be the SEO catalyst you’ve been looking for.
By keeping all users in mind and optimizing each image with appropriate alt text, your website can achieve greater visibility and provide a better experience for everyone who visits. This, in turn, not only helps you adhere to best SEO practices but also promotes a more inclusive web – and that’s a win-win situation we wouldn’t want you to miss.
