Optimizing your image alt text might seem like a bit of a dry topic at first, but stick with me – you’ll see how satisfying it is to get it right and how beneficial it is for both your users and your SEO efforts. Let’s dive into the nuts and bolts of optimizing image alt text for SEO and accessibility.
What is Image Alt Text?
First things first, let’s make sure we’re all on the same page about what image alt text actually is. Alt text (or alternative text) is a written description you add to an image’s HTML tag. Essentially, it’s a way to describe what an image is about so that search engines and screen readers can understand it.
Think of it as a layer of rich, textual information lying beneath your images. This text becomes incredibly useful for people who cannot see the images on your site and rely on screen readers to describe what’s there. Alt text also plays a significant role in how search engines index your images and helps your target audience find your content more easily.
Why is Alt Text Important?
SEO Benefits
Alright, SEO geeks, this one’s for you. Including well-optimized alt text can significantly boost your search engine rankings. When search engines crawl your site, they can’t see the images like humans do; they rely on the alt text to understand what an image represents. This helps them determine the relevance of your content to specific search queries, which can improve your position on search engine results pages (SERPs).
Example:
If you run a blog about cooking and have an image of a freshly baked pizza, a descriptive alt text like “Homemade Margherita pizza with basil and mozzarella cheese” could help your blog appear in relevant searches about Margherita pizza recipes.
Accessibility Benefits
Web accessibility is another crucial reason to pay attention to image alt text. Many people use screen readers to browse the web, especially those who are visually impaired. These screen readers read out the alt text to describe the images, making alt text a vital component for creating an inclusive web experience.
Example:
For a visually impaired person browsing an e-commerce store, alt text on product images provides necessary information they need to shop effectively. For instance, the alt text “Red hand-knitted wool scarf” would help them understand what the product is.
Best Practices for Writing Effective Alt Text
Knowing the importance of alt text is one thing; writing it effectively is another. Let’s dissect some best practices to make your alt text shine on both the SEO and accessibility fronts.
Be Descriptive and Specific
Your alt text should be as descriptive and detailed as necessary without being overly verbose. Aim to convey the purpose and context of the image.
Good Example:
“Vintage blue bicycle with a brown leather saddle parked against a white brick wall.”
Poor Example:
“Bicycle.”
Use Keywords Wisely
Although you want to use keywords in your alt text to help with SEO, don’t overdo it. Keyword stuffing can actually hurt your SEO efforts and make your site less accessible.
Good Example:
“Vintage blue bicycle parked against a white brick wall, perfect for city cycling.”
Poor Example:
“Keyword bicycle, keyword city bicycle, keyword bike, keyword blue bike.”
Keep It Short but Informative
Aim for 125 characters or less. This length is typically sufficient to describe the image without creating clutter. It ensures ease of understanding for screen readers and also helps maintain focus on the image’s relevance.
Example:
“Aerial view of a sunflower field at sunset.”
Avoid Redundancies
Don’t start your alt text with phrases like “image of” or “picture of.” Screen readers already announce that there’s an image, so there’s no need to repeat it.
Redundant Example:
“Image of a puppy playing in the yard.”
Optimized Example:
“Puppy playing in the yard.”
Context Matters
Consider how the image fits within the content surrounding it. Your alt text should complement the text on the page and provide additional information as needed.
Example:
If the image is part of a tutorial on planting flowers, alt text like “Gathering tools for planting, including a trowel, gloves, and a watering can” would be beneficial.
Examples of Optimized Alt Text
Let’s put these principles into action with some practical examples.
| Image Description | Poor Alt Text | Optimized Alt Text |
|---|---|---|
| A scenic mountain range | mountains | Scenic view of the Rocky Mountains at sunrise |
| A plate of pasta with tomato sauce | food | Gourmet spaghetti with homemade marinara sauce |
| A smiling woman holding a yoga mat | woman | Happy woman holding a blue yoga mat after a workout session |

Keyword Stuffing
While it’s essential to include relevant keywords, cramming too many into your alt text can do more harm than good.
Leaving Alt Text Blank
Never leave your alt text blank. Even decorative images should have an empty alt text attribute (alt=””) to signal screen readers to skip over them.
Using Generic Descriptions
Avoid using overly generic descriptions like “image,” “photo,” or “graphic.” Specificity is crucial for both SEO and accessibility.
Ignoring Context
