Image Alt Tag SEO: How to Add SEO Alt Tags for Web and Image Results

On page SEO is extremely important when it comes to SEO results. It’s fairly easy to set up, depending on the CMS platform you are using (i.e. Shopify, Wix, etc.).

In this blog, we will dive deeper into what alt text is, how it helps, and why it matters. Additionally, we will explore how to set up alt text for various CMS platforms including Shopify, Wix, WordPress, and Squarespace.

What Does Alt Text Mean?

Alt text or seo alt tags are the words behind the image. In other words, search engines need to read code in order to understand what something is. The engine cannot physically see the image, thus alt text acts as the code, a way for marketers to tell the computer what it is viewing. This enables the search engine to better rank pages when it comes to their on page SEO results. 

Do Image Alt Tags Help SEO?

Do alt image tags help with seo? Yes, an image alt tag helps the user in two specific ways. The first benefit resides in the fact that search engines use alt tag seo to help rank pages and build a database of information. Because of this, alt text increases page optimization and can help drive clicks in Google Web search results. Likewise, an alt tag in seo also allows for images to rank on their own merits and drive clicks in Google Image search results.

Alt Text Examples (WEB Search)

So for example, one of the keywords we ranked for through the Root & Branch site is non brand search.

If you look up “non brand search” in google you’ll see Root & Branch is ranked about fourth on the page with the seo alt tag “branded versus non branded keywords…” This drives traffic to our site through Google Web search results.

However, there can also be traffic from Google Image search. If we click on the image selection in google search, we can see images from and to the Root & Branch site appear four times. This article is ranking and driving traffic to the Root & Branch site through both Web and Image search results, which we can see the analytics for within Google Search Console under the search type filter. So you can see for Root & Branch, Image search does not bring a huge amount of traffic to the site.

However, this is not the case for all sites. is another site that has a huge amount of traffic for Image search. While the website has way more clicks over the last sixteen months from Google Web search, it still has nearly half as many clicks from Google Image search (66,400). Without an image alt tag on each on screen element, all of that traffic would cease to exist.

SEO Alt Tags Quicktip:

If you’re looking at any image on the page and you right click on it and inspect the element (F12 Key), you’ll be able to see if that image has alt text set up for it.

Image Title Tags

An image title tag or title text gives the user additional information about the image they are viewing. So, while it is not nearly as important as alt text for SEO and page accessibility, it can be useful. Title text can be viewed by hovering over an image with your mouse.

How to Generate an Image Alt Tag in Various CMS Platforms

Now, let’s talk about how we do it? How do you generate an image alt tag from platform to platform? At first glance, the task at hand may look tricky, but setting up alt text can be done quickly as its fairly easy. First, we’ll check out WordPress as it is perhaps the easiest. Then we’ll look at Wix, Squarespace and Shopify.

SEO Alt Tag Examples (IMAGE Search)

  5. Note: Squarespace automatically applies the filename of an image to its alt text description
  6. To complete the change, make sure to Save the page in the top left corner

Note: When we write the seo alt tags description, we want to use a relevant keyword. However, we do not want to stuff in keywords that might be great for ranking but are not an accurate description of the image itself. We are trying to thread the needle in order to be really useful in describing the image for search engines and normal traffic on your website. 

Shopify SEO Alt Tags

The last CMS platform we’re gonna learn how to generate alt text on is Shopify. Let’s say you are building a new store and you are beginning to sell products through that online store.

Alt Text Generators

Alt Text Generators are algorithms that analyze the content found in an image and create complete sentences of human readable language describing what is found in the image. The WordPress plugin below for example, gets this description and adds it as the alt text for each image uploaded while the plugin is active.
