Is Alt Text A Ranking Factor For Google Image Search?

In the world of SEO, understanding the intricacies of ranking factors is paramount. One question that often arises is whether alt text, also known as alternative text, plays a significant role in determining the rankings of images in Google Image Search. In this article, we will delve deep into the subject to provide you with a comprehensive understanding of alt text's impact on your organic search rankings.

Alt Text: An Introduction

Alt text, short for "alternative text," is an HTML image attribute that serves a crucial purpose in web accessibility. It allows you to create a text version of an image, which can be displayed when the image cannot load or when there are accessibility issues. This text description ensures that individuals with disabilities using screen readers can understand the content of the image.

Alt Text as a Ranking Factor: The Evidence

The debate surrounding alt text's influence on Google Image Search rankings has been ongoing, and it's essential to examine the evidence to make an informed judgment.

Google's Emphasis on Alt Text

Google places significant emphasis on the role of alt text in getting images recognized by its Image Search. In Google Search Central's Advanced SEO documentation, there is a section dedicated to "about alt text." Google highlights how it uses alt text along with computer vision algorithms and page content to understand the subject matter of an image. Additionally, alt text can serve as anchor text when an image is used as a link.

While Google doesn't explicitly state that alt text directly improves rankings, it does issue a caution to website owners. It advises against improper use of alt text, emphasizing the importance of creating informative, keyword-appropriate, and contextually relevant alt text. Keyword stuffing in alt attributes is discouraged, as it can lead to a negative user experience and potentially categorize your site as spam.

Good and Bad Alt Text Usage

To illustrate best practices, Google provides examples of good and bad alt text usage. This guidance helps content creators craft alt text that aligns with Google's expectations and user experience.

Pre-Populated Alt Text

Google Sites Help documentation mentions that some images come with pre-populated alt text, often including keywords that may not align with your optimization goals. It's essential to review and modify this alt text as needed.

Alt Text for Images Used as Links

When using images as links, Google recommends treating the alt text for those images similarly to anchor text in text links. However, overusing images for navigation purposes is discouraged, and text links are often a more suitable choice.

Insights from Google Search Advocate

In 2020, John Mueller, a Google Search Advocate, shed light on how Google uses alt text. He explained that alt attributes help Google better understand images, particularly for Image Search. While alt text might not be a priority for web search, it plays a crucial role in Image Search rankings. When you want images to appear in Image Search results, using alt attributes effectively informs Google about the image's content.

Moz's Perspective

Moz, a reputable source in the SEO community, offers insights into alt text's role. Instead of labeling alt text itself as a ranking factor, Moz suggests that alt text provides an additional opportunity to include target keywords. Given that on-page keyword usage remains a significant ranking factor, creating alt text that describes the image and incorporates relevant keywords is advisable.

Google Developer's Confirmation

In a Twitter discussion in 2021, Google Developer Martin Splitt confirmed the importance of alt text for SEO. This confirmation further solidifies the role of alt text in optimizing web content for search engines.

Alt Text: Not a Magic Bullet

It's essential to recognize that alt text, while valuable, is not a magical solution to SEO. Mueller reiterated this point during a discussion about optimization for indexing purposes in 2021. Alt text serves as an essential accessibility tool for screen readers and contributes to Image Search rankings but should not be viewed as a panacea for all SEO challenges.

Alt Text As A Ranking Factor: Our Verdict

In conclusion, alt text is undeniably a ranking factor for Google Image Search. Crafting descriptive, non-spammy alt text is crucial for enhancing the visibility of your images in Google Image Search results.

However, it's important to note that alt text does not hold the same significance for Google Search as a whole. Google has clarified that alt text functions similarly to regular page text in overall search rankings. While not a separate ranking factor for your page's content, alt text remains a valuable asset.

Ultimately, alt text should not be disregarded but embraced for its role in accessibility and its contribution to Image Search rankings. When creating alt text, consider what you want users who rely on screen readers to understand about your images.

In the world of SEO, every detail matters, and alt text is no exception. By optimizing alt text effectively, you can enhance the accessibility and discoverability of your visual content in Google Image Search.
