What is Image Optimization?

You might have heard this term thrown around in conversations or seen it online somewhere. Let us give you an understanding, how to optimize images for the web and eCommerce images.

With image optimization, you are trying to reduce the file size of the image as much as possible without affecting the quality of the image to a great degree.

Knowing about website Imagery Guidelines are mandatory for any web store or blog owner or content strategist. Web and eCommerce image optimization is helpful for both search engines and humans.

Image Optimization for web

Website owners do this so that their images can rank better on Google and other image search engines.

To them, it should look attractive enough to warrant their attention. However, having visuals is just the first part of the process. The website then has to optimize those visuals so that the entire site loads faster.

This is important to prevent the bounce rate from increasing on the pages.

When a user enters a page, they leave if the load time takes too long. This affects the bounce rate of the website, eventually reducing its SEO rankings on Google’s search engine results page or SERP.

Before we look at how to optimize your images, let us quickly look at why it is important for you to have quality images on your website.

Why are High-Quality Images Important for Your Website?

When people enter your website, you should know that a picture is more than just a thousand words. It is the gateway to all the information that you can easily show the viewer. It affects your sales. It shows your brand’s personality. No one likes to look at a blurred image or squint his or her eyes to check at a small image. You need to work to give a user experience that will make viewers return to your website.

Not only do visuals aid the user’s experience on your website, but it will also attract potential clients. Your customers or clients might not trust a site with outdated visuals. Looking at a page with crisp and quality imagery gives them the confidence that they are approaching a brand of distinction.

According to marketing expert Jeff Bullas, in an online store or eCommerce platform, people react more towards the visuals of the product than the features that it brings to the table. Image Retouching service can help you in this respect.

More Views

Visuals get more views on your website. As mentioned above, it will also encourage people to return to your website for more views.

This gives you more chances to convert potential customers or clients. In other words, visuals become an integral part of your revenue if you have an e-commerce store.

User Engagement

While examining visuals, people tend to stay longer on pages. This affects the average time spent on a page. So, maintaining Website Imagery Guidelines

If you have links on the page, people tend to click on them more as they have already looked at the page for a long.  

Decreased Bounce Rate

The above two factors affect the bounce rate. A higher bounce rate tells Google that people do not find value in your website.

Google will take this information and bring your website down in the search results. This affects your chances of finding customers and visitors to your site.

If you are running an e-commerce platform, this becomes a big cause for concern as your revenue depends on the number of visitors you have on your website.

The more visitors you have, the more purchases there are bound to happen.

How Do You Optimize an Image for a Website?

There are many ways you can optimize your images. We will give you details on each method but also share some valuable information along the way. 

Choosing Your Preferred Image File Type

If you are saving images for your e-commerce platform, then you should consider three essential file types. These are:  JPEG  GIF  PNG

Each of these file types gives you its own set of advantages and disadvantages.

Preferred Image File Format for web

Let us try to examine each one of them separately.  And find out the good bad and ugly file types.

JPEG The most popular image type

One of the most commonly used image types is JPEG. You can see this not only when people share files, but also in the images that are used online.

So why JPEG is the most commonly used image format?

One of the main reasons is that JPEGs are small when it comes to filing size. However, when you have images or photographs with many colors, then you are better off using a JPEG, as the file type provides a large color palette.

  • This allows you to preserve the colors of the image you are working with.
  • You can save the JPEG in different qualities, each having its own advantages.
  • If you save in high quality, the image will have a large file size, though not as large as PNG or GIF.
  • Medium quality gives you the advantage of colors and the benefit of saving in size in moderate quantities.
  • Low quality is all about reducing the file size as much as possible.
  • You will notice that icons are usually saved in low quality because they do not occupy a large space on a website.

PNG – Portable Network Graphics

PNG-Portable Network Graphics

PNGs are also commonly used on websites, but not as much as JPEGS. If you are using Adobe Photoshop to edit your images, you will have the option of saving the file in PNG-8 or PNG-24 format.


A PNG-8 gives you a smaller size image with it will feature fewer colors, reducing the vibrancy of the image.


The PNG-24 is the opposite; it gives you a wider palette and the image size will be much larger.

Now, million-dollar questions are:

  • But why do people use PNGs over JPEG?
  • Are quality and color the only reasons to choose PNGs?
  • When to use them?

After all, that does not make them any different from JPEGs.

    ✔ The thing about PNGs is that they can handle transparency.

    ✔ This becomes important when you want to project your logo on a blank background.

   ✔ Or when you want images to have transparency in or around them.

GIF – Graphics Interchange Format

Graphics Interchange Format-Gif

For e-commerce platforms, GIFs are a great way to advertise on their pages. They can carry information with a short animation that is set on loop. People are attracted to images that grab their attention with novelty, which is the idea that there is something new to discover in an object or idea.

  ✔ GIFs give viewers a new image as it goes through the animations.

  ✔ In order to optimize images, ensure that you choose the images properly.

  ✔ You do not have to stick to one image only.

However, make sure you know where your visuals are going and if you require one type of file over the other.

Website Imagery Guideline Tips for Saving The Image Properly

You might think that this is obvious, but too often than not, you will be surprised at how a lot of people do not save images right.

  • When you save images, you will notice that they have sizes in KB, MB, or GB.
  • If your image is in GB, then you might want to consider changing its size.
  • But before that, here are a few things you should know.

Name Your Images Properly

Well, let us take the example of the Samsung image that we mentioned above, you need to think about how people will search for the product.  So you should think of naming it as Samsung-s7-smartphone or Samsung-note-8-smartphone.

Google will use these cues so that people can easily find the image.

Fix Right Dimensions

Dimension is the length and width of the image. It will help you get an idea of where you can fit the image on your e-commerce platform.

Compress Properly

Compression is the process of reducing the file size of the images. There are many ways to do this, both directly through the software, or online platform.

Rename Your Images

When you have followed the above steps, let us get down to naming the file. Let us take an example in this case. Say you have an image of a Samsung smartphone that you would like to add to your e-commerce platform. Typically, most people upload the image without changing its file name. This way, you have a random assortment of digits and numbers.

The best resolution for web

People often progress misconceptions about these topics. The reason behind is laid on the basics.

We know that the best quality images always contain a higher resolution. But this is not true for all pictures beside you must keep an eye on file size.

√ Choosing the best resolution for the web actually doesn’t mean saving it on high res but saving an image that is clear and shows enough details.

How do Optimized Images in E-Commerce To Increase Sales?

If you look at the structure of a typical e-commerce platform, you will notice that it is filled with images. There are pictures on your product pages to display the product in different ways.

You will notice that some product pages have multiple images, as much as ten in some instances.  Your category pages also have images to give a strong visual appeal to the viewer. Of course, your homepage has numerous images.

In fact, your homepage is filled with all kinds of visuals, from banners to pictures to graphics.  Now all of these images take space and affect the load time of your website.   Google takes into account the load time of a website.  

With all the images on an e-commerce website, how can someone make sure that their website does not take too much time to load?

For that reason, you need to find a solution whereby you can still show all your visuals but retain page speed.

How Can You Achieve This Level of Sales?

That is where image optimization steps in. It gives you greater control over the loading of your website.

   ✔  You are giving better chances to attract customers.

   ✔  The Website does not have to sacrifice images.

   ✔  You simply have to render them in the best, and fastest, way possible.

Here is how they contribute to the sales of your e-commerce platform.

Increased Interaction

Getting proper images, helps to grab the attention of the viewer. The images will encourage them to head over and click on your products. Their first impression will always be the way the product looks. They want to feel confident that the quality of the product is right. Surprisingly, a good image can help convince them of the quality.

More Clicks Increase Traffic

With good images, you can draw more clicks. This, in turn, increases your page ranking. Once it does that, more and more customers will enter your site to make a purchase.

Now, Let us analyze it this way.  If load times increase, there are fewer people interacting with your product pages. And when that happens, you lose sales. You need to retain users. You should give them the information they require as soon as possible.

This is why, by optimizing images, you are not keeping the customers waiting.

  •  You are giving them quick cues so that they can make up their minds immediately.
  • Wait too long and you will have customers heading over to your competitors so they can have a better working experience.

If you are operating an e-commerce platform, then you have to know that choosing your product shows is very important.

Many e-commerce platforms have multiple shots, where they show the top, bottom, and side angles of the products they are displaying. 

Let us take the example of a smartphone again. Show images of the box. Then show images of the phone outside the box. Then show multiple angles of the phone itself.  This is just one of the ways you can do this.

There are many ideas that you can focus on to get the most of our product shots.

Always Test Your Images

Always Test Your Images

Once you are done optimizing them, make sure that they work properly on the website. Test to see if the images load fast.

See if you can see the image clearly and if the dimensions are right.   Most importantly, you need to see if the images are mobile-friendly as well.

If your visuals are looking great on a desktop, it does not mean that it is the same case on a mobile device.  Once you confirm that the images are loading properly, go ahead and keep them. Otherwise, replace the images so that you have the right ones.

Prepare your Alt Tags

Prepare your Alt Tags

An alt tag is a description of the image that will describe what the photo looks like. Most e-commerce platforms already provide you the option of adding alt tags. When they do, simply enter the text alternative for the image that makes it easy to describe the image.

Add Context Shots

Add Context Shots

A context shot is a picture that shows how your product is displayed in real life. For example, if you are displaying furniture, then they should be shown in a living room.  

In a similar way, try to show how your images look when actually being used by a person or inside a situation.
