Here are a few questions that arise out of the above.

  • Is this important?
  • What should they do?
  • How should they overcome the problem?

Let’s start by answering these questions one by one.

Yes, it is important. For an e-commerce site that sells its products online, it is important to have a clear, concise image in the correct dimension and proportion and should load quickly.

Everyone should know it irrespective of the job – a marketer or the designer.

So, here is what one is required to do:

Images are responsible for more bytes than any other part in an e-commerce site. The size and other features can either help gain or lose. This is responsible for e-commerce conversions and retention of the customers. Therefore, one of the best means to make your website work better is by improving its SERP ranking with image optimization.

Below are the areas the e-commerce site should work on…

1.The Image Quality

Use high-quality images. This doesn’t mean you have to use smaller, blurry images just to fit into the KBs required.  Use the SEO image tools to reduce the size, but maintain the quality. These remove Exif(Exchangeable image file format )data/meta and similar things but still keep the image as clear as it should be.

Furthermore, internet connections are getting better day by day. This implies that downloading a larger file isn’t as difficult as it has been so far. But you need larger images to be able to zoom the product images, an important feature for the e-commerce sites.

2.The Image – File Type and Format

Large screens, high resolution, are becoming an order of the day. But does that mean we don’t need to optimize the images? Well, we need to still. Though cameras today are much more sophisticated (thanks to the advancement in technology) and the end result is high-end photographs with great images. But large images can pose huge hassle for an e-commerce website by increasing the load time. This may annoy a visitor who can be a potential customer and drive him away. For him/her, the important factor is load time. Alternatively, it affects the Google rankings. The size of the image affects the load time which can be the reason behind the high bounce rate. Hence, reduce the image size.

Here is how to do it…

File Type

The difference between the three lies in the quality of the image.

JPEG (Joint Photographic Experts Group, the name of the developer)

This format is best for complex images and photos. It supports a minimum of 16 images. The best part of this format is its small size and good quality. The file size can be adjusted. The JPEG lets you compress images as lossless and lossy. Smaller loss implies a larger file size.

Image – File Type and Format

Use it on: All product images, photographic images, and multicolor images.

PNG (Portable Network Graphics)

This kind of format is required to save a large number of colors and also the transparency. It utilizes compression to store any amount of colors. It is further of two types: PNG-8 and PNG-24

  • PNG-8 is best for images with simple colors like a logo or the buttons. It supports transparency.
  • PNG-24 supports a large no. of colors. It can be used for photos and complex images like JPEG. It supports transparency.Portable Network Graphics

Use it on: file size is secondary, image quality is important.

GIF (Graphics Interchange Format – format for sharing images)

This format is utilized for logos, icons, buttons, symbols, simple graphics and animation. This kind of format is great for photos or color backgrounds. This is helpful as there would be no border between the images. It shouldn’t be used for photos because of its limited amount of colors, just 256. Before the PNG came into effect, GIF was commonly used.

Graphics Interchange Format – format for sharing images

Use it on: small images (icons and thumbnails), all animation, and an image such as a logo with a few colors.

What is your best bet for SEO image optimization?

  • For a product image – JPEG with the image quality of 50-80 units
  • For images with large planes, don’t use JPEG. It is infamous for developing image distortion. PNG is better in this regard.What is your best bet for SEO image optimization?

3.Image size

The image size implies the dimensions of the image such as 852 x 852. To elaborate on this, the file size is the amount of space required by an image to store on a server.

Understand this; a larger file size takes more time to load. But, an image can have a large size and can be still 2MB or less. So, keep the image size to 1-2 MB. Smaller images imply the site loads quickly, has low bounce rate and gains repeat customers.

  • WordPress hosted site – use Yoast SEO. It adds the content of the images instantly. If you don’t have Yoast SEO, then install it. Make sure the ‘enable’ button is on and then save the changes.

5.File Names

It is important to give the right names to the files. This is a big deal for the search engine crawlers. It is unfortunate but a lot of marketers do not bother much about this. They do not change the name of the picture. It is usually the code or number assigned by the phone or computer.

To set things right for the search bots, name the image in a to-the-point manner so that understanding it isn’t difficult. For SEO, a keyword rich image is highly beneficial. Manually edit the HTML of the image for every upload. Keep the file name short; keyword-rich, and correct describing what is represented in the image.

For example, if you are selling white ballerinas, white ballerinas should be present in the image name.

6.Alt Tags

It is the description assigned to the image and it appears in the website’s code. This implies that if the image is not visible or displayed for any reason, there will be a text description shown to the visitor and he will get an idea what the image is all about. Add keywords to the alt attribute. This helps one rank better in the Google SERPs.

Alt TagsIt serves three functions, primarily:

1.SEO crawlers can read it which means better SEO.

2.It is a code that tells a browser what should be displayed when the image doesn’t load properly. This can be useful when the site has some loading issues.

3.It is a boon for the visually impaired people. They will know it by using the screen readers due to the alt attribute. When a cursor is held over the image, the screen reader can read the alt attribute description to them.

Here is how to do it:

  • Use plain language
  • Products with serial numbers or model numbers should be used.
  • Do not use too many keywords. Stuffing may fire back.

Keep checking the website. Make sure alt tags are filled appropriately.

How to do it in WordPress?

  • There is an option of adding both a title and an alt tag in WordPress.

It is a great way to sell other similar products to customers. Some websites display it while the customer is confirming his/her order or while the customer is still browsing through the products. This is called upsell.

It is an add-on, additional product or an upgrade which is introduced by a seller after the purchase is made. Sometimes there are many images shown at the bottom.

But, what if the images do not upload properly?

You lose.

The tiny image sizes (which are less than 70 KB) are great for your businesses.
