The Importance of Alt Text in SEO #

Alt text, also known as “alternative text” or “alt tags,” is a key component of search engine optimization (SEO). It is the text that appears in place of an image if the image cannot be displayed for any reason, such as slow loading times or a broken image link.

But alt text serves a much greater purpose than simply providing a backup for images. In this article, we’ll explore the importance of alt text in SEO and how it can help improve the visibility and ranking of your website in search engine results pages (SERPs).

How Alt Text Affects SEO #

Alt text helps search engines understand the content and context of an image. By providing a concise, relevant description of an image, alt text helps search engines index and understand the content of a page more accurately. This, in turn, can help improve the ranking of a page in search results.

In addition to helping search engines understand the content of a page, alt text can also improve the user experience. When an image fails to load, users can still understand the context of the image and its relevance to the page through the alt text. This can be especially important for users with visual impairments, as alt text can be read aloud by screen reader software.

Best Practices for Alt Text #

To make the most of alt text in terms of SEO, it’s important to follow best practices when writing alt tags. Here are some tips to keep in mind:

  • Keep it concise: Alt text should be short and to the point, typically no longer than a few words.
  • Make it relevant: Alt text should accurately and concisely describe the content and context of the image.
  • Avoid keyword stuffing: While it’s important to include relevant keywords in alt text, avoid cramming too many keywords into a single alt tag. This can be seen as spammy and may even result in penalties from search engines.
  • Use descriptive language: Instead of using generic terms like “image,” “photo,” or “picture,” try to use descriptive language that accurately describes the content of the image.

Alt Text in Practice #

To see how alt text can be used in practice, let’s look at an example. Suppose we have a page about “vegan recipes.” On this page, we have an image of a vegan chocolate cake. Here are a few examples of alt text that could be used for this image:

  • “Vegan chocolate cake with chocolate frosting and raspberries on top”
  • “Delicious vegan chocolate cake recipe”
  • “Chocolate cake made with vegan ingredients”

All of these alt text options accurately describe the content and context of the image, while also including relevant keywords.
