Turbocharge your Amazon listing optimization and transform your image keywords Amazon A+ Content fields into an SEO advantage! In this blog you'll learn how to add keywords to Amazon listing image keyword fields

What are Amazon Image Keywords?

Outside of Amazon, image keywords are known as “alt image text” or "alt text" (alt text = alternative text). We will use these terms interchangeably throughout this article.

This type of text, which is normally invisible, makes product images in the eCommerce sphere accessible to the visually impaired. Image keywords will also appear when a photo doesn’t load properly. They provide a digestible word picture. If a picture is worth a thousand words, Amazon’s 100-character image keywords are priceless when it comes to your Amazon SEO and ability to connect with customers. 

Oh, and did we mention that search engine algorithms will also rank and index your image alt text? This means these fields are another way to get your Amazon product listings visible in the search results.

Behind-the-Scenes Amazon SEO 

There are two important factors at play in developing effective image keywords. 

First, image keyword fields give search engines a better idea of how to index your images. The benefit: your product listing's SEO gets a boost in the search results. Amazon now states that image keywords “help your product appear in search.” That makes the alt text field an ideal home for extra keywords that pertain to your product. 

Second, you will usher in traffic. If your product listing is properly optimized, this can increase your conversion rate (aka more sales!) by properly describing your product for the visually impaired. 

If you are selling a ball cap and your image alt text is “image.jpeg” and another brand uses the same image with the alt text “smiling man wearing blue hat with white Royals logo,” which would you choose? 

If you are using lifestyle photos, an image alt text strategy that we definitely recommend for your listing, the way you choose to describe your images is crucial. Your choice of words creates a visual for how the person will feel when they use the product and boosts your Amazon product listing overall. 

Kickstart your SEO to encourage buyers to click on your listing, and then encourage conversion with accessibility. Bolster your SEO, build trust, and they will click. 

The Nitty Gritty: Amazon Guidelines

You are beginning to understand just why image keywords are vital to your listing. So let’s dive into a deeper understanding of how to apply this knowledge. 

To upload their product listings, sellers with registered brands who want to create  A+ Content,  Premium A+ Content, or A Plus Content KDP pages, must fill out the image keyword fields. Each A+ content module image features an accompanying field for alt text. Once you’re ready to get started, here are the more technical requirements you should keep in mind:

  • 100-character limit
  • No need to be grammatically correct
  • No repetition of any words (this is why alt text is often not grammatically correct)
  • No punctuation
  • Avoid restricted words
  • This version of image alt text can have spaces
  • Image keywords on Amazon are required for each individual image, meaning:
    • Standard image header module will have one image keyword fields
    • Standard four image A+ module will have four image keyword fields
    • Comparison table modules will have an image keyword field for each product you add to the table.
  • Despite its misleading name, this field is not intended solely for search terms, so don’t keyword stuff!

How to Write Accessible Alt Text that Engages SEO 

  • Prep: Review your keyword research to create a photo keywords list that you can use for the next 5 steps.
  • Step 1: Utilize 1-2 keywords for each image alt text field, but resist the urge to keyword stuff. Describe the image accurately. Your phrases should be impactful for a visually impaired customer.  
  • Step 2: Make it clear what the image is by using colors and descriptive language.
  • Step 3: Stick to Amazon guidelines and avoid restricted content. 
  • Step 4: Avoid superlatives. Say “blue hat” instead of “pretty hat.” Keep it objective.
  • Step 5: Don’t use punctuation. Leave out hyphens, commas, and apostrophes.

Tale as Old as Time: Alt Text and Keyword Stuffing

Keyword stuffing is tempting but detrimental to the meaning of your image keywords. This approach turns potential conversions away because it feels impersonal. Below, we’ve created an example of keyword stuffing and explained how it reads. 

For this image, you are selling a multivitamin. Your keywords are vitamin A, vitamin D, multivitamin for men, and multivitamin for women:

 happy man taking red multivitamin for men and women with glass of water

Not Even Okay: multivitamin for men multivitamin for women with vitamin A vitamin D capsule


❌ Image keywords don’t describe the actual image

❌ Many words are repeated

❌ The phrase doesn’t make sense


On Point: smiling man taking red multivitamin for men and women with glass of water

✅ Strong balance of keywords and description

✅ No repetition

✅ Evokes the feeling the customer might have when taking the vitamin
