As search engines increase their capacity to understand any picture on a website and user experience gets richer with visual information, alt text for photos is becoming more significant.

Visuals are almost always required when publishing material on the internet these days. Embedded pictures on the website are significantly more pleasant for users than clicking on a hyperlink, and Google SERPs are catching up to this.

In fact, visual material is often the top-ranking result of a Google search. This is what the SERPs look like when we search for “seo resume examples,” for example:

How to Write Effective Alt Text

The target keywords may be integrated into the alt text in a relevant and meaningful manner, which enhances the content and improves the user experience. 

When it comes to image optimization, remembering to include the focus keyword in the alt text isn’t the only consideration. When creating alt text for photos on a page, keep the following in mind:

  • Describe the picture as objectively as possible: alt text is shown while an image isn’t loading, therefore it should be a logical explanation of the image.
  • Give the picture context so that crawlers can appropriately index it.
  • Keep it brief and simple: use the longdesc feature for lengthier explanations (note: avoid terms like “image of” or “picture of” – it’s self-explanatory since alt text is the image’s description).
  • Use keywords, but don’t pack them in: the same guidelines that apply to excellent content apply to alt text. Keyword stuffing isn’t effective in content and isn’t effective in alt text.

Image SEO Alt Text Best Practices

Avoid utilizing visuals in lieu of text if you want to be SEO-friendly. Because search engines can’t read as well as people, employing an image instead of real text confuses crawlers and may harm rankings.

As a general guideline, make sure all photos on a page have alt text. Images used as buttons are included in this category. Descriptions like “apply now” or “subscribe to newsletter” might be used as alt text for buttons.

From the worst to the best, here are some examples of alternative text.

Let’s take a look at some samples of alt text, ranked from worst to best:

Identifying Problems with Image Alt Text

Even when we do our hardest to produce alt text that is effective, we sometimes overlook something.

Our Site Audit Tool will help you identify problems with pictures on your website when you wish to optimize them for the web. 

Images with flaws

Because broken photos cannot be shown correctly, they produce a bad user experience and give the impression that your website is of low quality. Broken pictures may harm a site’s rating if search engines see them.  


The Site Audit tool will show you what’s causing the image to break. After that, you’ll most likely need to fix:

  • A misspelled URL or an incorrect file path: fix a mistake in the URL; if the image file has been relocated, update the URL to link to the new location.
  • If an image file was destroyed or damaged, replace it with a new one; if the picture is no longer required, remove it from the page’s HTML code as well.

The only distinction to be made here is between broken internal pictures and broken exterior images. Because you have no control over the external pictures, the best course of action is to replace them entirely.

Without Alt Attributes Images 

An empty alt property, as previously stated, is a squandered chance for higher image search ranks. Furthermore, it does not provide a pleasant user experience for visually challenged individuals. 


The Site Audit Tool may be used to analyze any photos that lack alt attributes, making it easy for you to step in and fill up the alternative attribute with the proper wording. 

Here’s where you’ll see the empty alt attribute:

  • img src=”magename.png” alt=” “> img src=”magename.png” alt=” “>

Replace this with:

  • img src=”imagename.png” alt=”well written alt text with keyword”> img src=”imagename.png” alt=”well written alt text with keyword”>
