What are Alt Tags? How to Increase Website Traffic with Image SEO

To ensure the success of your website, one of the most important things you can do is to optimize it for search engines.

There are many ways to achieve this goal, regardless of scale.

A smaller but still important task is to optimize your image replacement text.

“alt tags”, sometimes called “alt text”, is an important consideration for accessibility, but it can also have a positive impact on the search engine optimization (SEO) of your website.

Even if most of your readers will never see this “hidden” information, the alt text in the image will provide sites like Google with valuable data about your content so that it can be presented to the appropriate search engines.

When talking about image search engine optimization, the first thing that usually comes to mind is to optimize alt tags, but you should include more content when optimizing images.

In fact, it’s safe to say that image optimization is one of the most overlooked areas in SEO; but it doesn’t have to be that way.

It is not uncommon to find that the images of a site have huge file sizes, ambiguous file names, and the display size of these images on the site is much smaller than the original images.

The common problem is that the beginner’s guide to SEO only covers the basics, which means that optimizing alt tags is almost everything mentioned.

But let’s not forget that image search itself is a big deal and can bring a lot of traffic to your website.

Let’s face it, who didn’t use it to search for pictures of cats?


What is alt text?

Alternative text, also known as the technically incorrect “alt attribute,” “alt description,” or “alt tag,” is used to describe the appearance and function of images on a page in HTML code.

The alt tag is used by screen readers, which are browsers used by the blind and visually impaired. These screen readers tell them what is in the image by reading the alt tag.

When you hover over the element, the title attribute is displayed as a tooltip.

Therefore, for image buttons, the image title can contain additional calls to action. However, this is not the best practice.

Each image must have an alternative text. Not just for SEO purposes, but also because blind and visually impaired people don’t know what the image is about.

The title attribute is not required.

Also, it doesn’t make sense to add it most of the time. They are only available to users of the mouse (or another pointing device), and the only situation where the caption attribute is required for access is on  <iframe> and <frame> tags.

If the information conveyed by the title attribute is relevant, please consider providing it in plain text elsewhere. If it is not relevant, please consider deleting the title attribute altogether.

Alt text usage:

  1. Adding alternative text to photos is the primary principle of network accessibility. Visually impaired users using screen readers will read the alt attribute to better understand the images on the page.
  2. If the image file cannot be loaded, the alternate text will be displayed instead of the image.
  3. Alternative text provides better image description/context for search engine crawlers to help them index images correctly.

The highlighted text displays the alternative text (alt attribute) of the image on the left.

Alt text example

<img src="catdrinkparty.gif" alt="kittens drinking">

Best alt text format

The best format of the alternative text is sufficiently descriptive but does not include any spam keyword filling attempts.

If you can close your eyes, ask someone to read the alt text to you, and imagine a fairly accurate version of the image, you are on the right track.

Let’s take a look at some examples of alternative text for this stack of books picture

Okay:<img src="books.png" alt="books">

This alt text is only “okay” because it’s not very descriptive. Yes, this is an image of a stack of books.

But, there’s more to be said about this image.


<img src="books.png" alt="stacks of books with different colors">

Here are some best practices to follow when creating alternate text

  • Use complete sentences, not words or phrases. This provides more information for human and robotic visitors.
  • Be as descriptive as possible and clearly explain what the image contains.
  • Include keywords in your alt tag. Keywords are essential to any powerful SEO strategy, and this is another place to integrate them. If your content has a main keyword, then you’ll want to use it in the alt text where appropriate. Especially for product images, including the item name and product identification is also a good idea.

If you keep these tips in mind, you will find yourself immediately creating effective image replacement text!
