Why it’s important to optimize images for Google Images
Google Images is a search engine feature that allows users to find images more easily and make them available for the user to find in searches.
For an image to be in the top results, it needs to be relevant to users, as well as optimized for the Google Images algorithm.
But why is it important to appear in the first search results?
When we search for a keyword that is related to images — a cell phone cover, for example — Google already provides, often in the first position of organic results, the images that may be more relevant to the user’s search.
Suppose you have an e-commerce that, among other things, sells mobile phone cases.
In this case, it is very important that your images appear in the search results, as users themselves can access your site through the photos they find most interesting.
Content about phone cases that doesn’t have images may not be very relevant to both users and Google’s algorithm.
And this applies to many other types of deals and terms.
But, after all, how to appear in the first places of the search engine?
How to generate more Google Images traffic to your website?
Image searches grow 10% a year, according to Internet Live Stats.
E-commerce sites are increasingly investing in getting traffic from Google Images because it brings a qualified audience that visually likes your product.
So, how to generate traffic from image searches?
In the image above, you need to differentiate the first line from the subsequent lines.
The first row is made up of ads , which are displayed through the Google Shopping platform and the advertiser will pay for each click received.
Next, starting from the second line, are the so-called organic ads, that is, the results that Google generates “for free” and that are its source of great reputation.
To appear there, you need to apply the well-known techniques of SEO (Search Engine Optimization), which means optimizing websites for search engines.
In other words, SEO helps your website to be in the top positions of Google, get more traffic and generate more sales .
And the search for images is a great ally.

How to Optimize Images for Google
You already know that SEO techniques help to reach the top of searches and you must imagine that Google wants to bring the best results to the user.
Google’s idea is to provide the best search experience and for that, we must divide the SEO strategies for Images into two fronts:
- EAT (Expertise – Authority – Trust) : this is how Google recognizes a good site and you need to meet the requirements and have a strategy based on SEO Experience ;
- Image Optimization : help Google recognize your image;
To optimize images, the first step is to have quality images preferably that other sites have never used.
Therefore, it’s no use going to Google Images, copying images from other sites and hoping to appear well positioned for them.
✅ SEO Checklist to Optimize Your Images
There are six technical aspects of your images that must be optimized for them to have good results.
Using the SEO techniques that we are going to talk about now, you can have images with great results.
Let’s get to know each of them in more depth:
☑️ File name: name your file legibly and with keywords
When adding an image to your website or blog, a URL is created based on the image’s filename. If you leave a random name like “IMG678.jpeg” it is more difficult for the Google robot to identify what the image is about.
Therefore, name the file with a keyword referring to the image to make its content easier to read and, consequently, increase its relevance.
In html, it would look like this:
☑️ Alt tag: make sure it contains descriptive text and the keyword by which your page will be found
The alt tag is an alternate description of your image. This part is also read by Google and, therefore, it is important that you use the appropriate keywords and according to the context of your content.
This description facilitates the process of placing image links on the web and even the visually impaired can read its content through the Jaws system, which can identify the images and speak their alt tag.
It is of great importance for an SEO strategy for Google Images to be efficient.
Inserting an ALT into your images is simple. In general, website platforms like WordPress, for example, already provide a space to add the alt tag to images.
In the case of e-commerce platforms, this is done automatically and usually brings the name of the product – in this case, you don’t have to worry.
You can also add it directly to the html text with the following command: alt=”text with relevant keyword”.
☑️ Image dimensions (width and height): prefer dimensions similar to 16:9 or 4:3 and width of 1024 pixels.
Image dimensions are important for two factors: user experience on your post and for Google itself.
If you search for an image on Google Images, you can see that the figures presented, in general, have dimensions similar to 16:9 or 4:3.
Our suggestion is that you follow the pattern of your results page or even your industry.
Try to keep images at least 1024 pixels wide.
This is the preference so that there is a standard in the presentation of images and organization of results.
Therefore, unless necessary, avoid using images vertically or with very non-standard dimensions.
☑️ Image Quality: Always ensure a good perception
Be careful when uploading very large files, it can affect your site’s loading speed and thus interfere with your users’ experience.
But do not worry…
There are several tools — some of them free — that you can use to compress images and make files lighter.
☑️ Image Size: keep under 100kb with the right tools
Size counts too. After all, Google wants to provide the best user experience.
That’s why you should keep your images at a reasonable size.
We suggest that the images have up to 100kb, maintaining, of course, their quality.
Use tools like TinyPNG or ILoveImg to reduce file sizes.
☑️ Domain and Page Authority also count for Google Images
In a largest SEO study in Brazil we conducted in the e-commerce segment, we found that domain and page authority are directly correlated with better positioning in search results.
When we analyze Google Images, we see that the first results tend to also be sites that have greater authority.
This reinforces the central thesis of the importance of link building in SEO strategies made to be winning.
More SEO Ranking Factors for Google Images
In addition to the optimizations that we have already mentioned, there are others that you can use to have images that are better ranked on Google Images.
1. Image context
One of the factors that Google takes into account when ranking photos is the context in which they were inserted into the content.
That is, according to the image information as ALT, it checks if the paragraph in which it is inserted, for example, has words that are related to the image.
Relevance can increase if an image of a cell phone case, for example, is inserted into a paragraph that talks about cell phone cases, that is, an image with context and coherence.
2. Interactions with the image
Google can detect when a user clicks on an image or makes any interaction with it.
If the image has a lot of interactions, he finds it more relevant to users. Therefore, the image may have better positions in Google Images.
That’s why it’s important that, when possible, you encourage engagement and create images with an attractive design that piques users’ interest.
3. Image caption
The caption is also important for users to understand what it is about and what its characteristics and highlights are, but it is far from being mandatory .
This can help in understanding the image and therefore improve user experience and readability by the algorithm as well.
The use of image caption should only be done on sites where it makes sense, especially news portals or blogs.
4. Be mobile friendly
Most website traffic, in general, comes from mobile devices.
Cell phones are practical and many users prefer to use them when buying things on the internet.
That’s why it’s important that your photos are the right size to provide the best mobile experience.
For each platform there is a recommended dimension so that the image doesn’t have a bad quality or doesn’t fit on the screen.
It is important that you adapt the images according to the platform to avoid these problems.
By applying the information in this post, your images can have great results on Google and drive more traffic to your pages.
Always remember to make attractive and relevant images according to the content.
