Optimizing images for SEO website promotion

Images play an important role in search results. Rich snippets and other special elements often include images, making visual search an important part of SEO. Optimizing images can lead to additional traffic from search engines such as Yandex and Google Images. Why miss this opportunity?

In this article, we will tell you how to properly optimize images on your website so that they help improve your rankings in search engines. And you will see that it is not as difficult as it might seem.

Why do you need image optimization for a website?

In order for a website to rank high in search results, it is important to consider several key factors regarding images:

1. Correct formatting (file name and attributes). This affects the likelihood that images will show up on search engines. Consequently, the likelihood of attracting free traffic increases.

2. Image size. This setting affects the page loading speed. Fast loading pages are valued by search engines, and sites with fast response times receive higher rankings.

3. The presence of the Alt attribute. This attribute is necessary for people with disabilities, as it allows the use of special programs that read information from the screen.

In addition, "heavy" images take up a lot of space on the server, which may lead to the need for more disk space or additional work to compress the images.

How to achieve first positions in search engine results

The image optimization required to achieve high rankings in search results is based on several aspects:

  • File size
  • File name
  • Image format
  • Presence of the Alt attribute

Image format

To upload images to site pages, you should use the following formats depending on the type of content:

  • If animation is required, use GIF format
  • For line drawings or infographics – PNG
  • For vector graphics – SVG, which allows you to scale the image without losing quality
  • For regular pictures – JPEG

Name of the picture

The correct image title (specified in the Alt attribute) helps search engines correctly determine what the image is about and allows it to be shown in search results such as Yandex Images and Google.

It is not necessary to include keywords in the title, although they can be useful. The main thing is that the file name matches the content of the image. Use Latin letters and separate words with dashes.

For example, instead of "IMG00025.JPG" use "devushka-u-okna". This name will help search engines better understand what is shown in the picture. For convenience, you can use online transliteration services, for example, translit.net or similar.

If the images are already uploaded, do not rename them. It is better to take this point into account in the future and adhere to the correct practices from the very beginning.

Optimizing the weight of the picture and its dimensions

One of the ranking factors is page loading speed. If a page loads slowly, users tend not to wait and will quickly leave the site. Search engines take this into account when evaluating sites. To speed up page loading, it is important to size your images correctly.

Compressing an image will help reduce its weight, which will result in pages loading faster without losing quality. You can use various online services to compress images:

  • Optimizilla
  • Compressor.io
  • Gutsli
  • Brain
  • Ptipych.io

These tools can reduce file sizes by 20-60%. You can also use Ahrefs Site Audit to analyze your site and get recommendations for reducing image weight.

Accelerate loading - caching

The caching option allows you to save images on the user's device, which reduces the amount of data transferred when visiting the site again. This helps speed up page loading and reduces server load.

To further speed up loading times, you can only show smaller versions of images on your home page, loading full-size versions only when needed. This is often used in online stores, where to get a closer look at the product you need to hover over or go to the quick version of the view.

Image quality

Search engines give preference to unique and high-quality images. Copied or heavily modified images will not help improve your site's ranking in visual search.

A search engine crawler can quickly determine the original source of an image, and if it is copyrighted, this can affect the ranking. It is best to use original photographs or graphic works. If this is not possible, you can search for images with an open license (for example, for non-commercial use). Good resources are:

  • Unsplash
  • shove
  • Pexels
  • Freerange Stotsk

Conclusion

Before uploading images to the site, you should do the following:

  • Resize image (width and height)
  • Perform weight optimization (best if the file size does not exceed 50 KB)
  • Give the correct title to the image
  • Make sure the image has an Alt attribute
  • It is advisable to specify a title that matches the content of the image
  • Add a caption to the image if necessary for registration

Visual content helps improve the page experience and increases search engine visibility. Optimizing your images will help you attract more users and increase traffic to your website. Once your images appear in search results, they will begin to generate additional clicks to your site. However, to achieve the TOP 10, it is important to use an integrated approach to promoting the resource.
