How to do Image Optimization for Better Website Ranking?

Image optimization is an essential aspect of Search Engine Optimization (SEO), given its significant impact on website ranking and user experience. Properly optimized images lead to faster loading times, improved user engagement, and increased organic traffic. In this article, we will discuss best practices for image optimization for better website ranking.

What is Image Optimization?

Image optimization is the process of reducing the file size of an image without sacrificing its quality. This is typically done to improve website loading times and overall user experience. Some common techniques for image optimization include compressing the image file, reducing its dimensions, and selecting the appropriate file format (such as JPEG or PNG) based on the type of image being used.

Importance of Optimizing Images on Website

Optimizing images on a website is important for several reasons:

  1. Faster page loading times: Large image files can slow down page loading times, which can negatively impact user experience and even lead to higher bounce rates. Optimizing images can help reduce file size and improve page loading times.

  2. Improved SEO: Search engines take website loading times into account when ranking pages. Faster loading times can improve your website’s SEO and help it rank higher in search engine results pages.

  3. Better user experience: Optimized images can improve user experience by making your website more visually appealing and easier to navigate. This can lead to higher engagement, longer session durations, and increased conversions.

  4. Reduced bandwidth usage: Large image files can consume a lot of bandwidth, which can be costly for website owners. Optimizing images can help reduce bandwidth usage and lower hosting costs.

Overall, optimizing images on a website is an important aspect of website design and can have a positive impact on user experience, SEO, and website performance.

Why Image Optimization Is Important for Website Ranking?

Understanding the significance of image optimization can help prioritize it in your SEO strategy. In this section, we will discuss the following topics:

  • How search engines use images to determine website ranking
  • The importance of image size and format for faster loading times
  • How images impact user experience and engagement.

1. How search engines use images to determine website ranking: Search engines use complex algorithms to determine website ranking. Images play a substantial role in these algorithms. Properly optimized images allow search engines to understand the context of a website visually, improving website indexing and ranking.

2. Importance of image size and format for faster loading times: Image size and format are crucial in website optimization. Large images take longer to load, leading to slower website performance and reduced user engagement. Choosing the right image format and reducing image size significantly improves website loading time, increasing user engagement.

3. How images impact user experience and engagement: Images play an important role in the overall user experience. Poorly optimized images cause a lag in website performance, leading to a poor user experience. Properly optimized images, on the other hand, improve website loading speed and user engagement, leading to increased organic traffic.

Choosing the Right Image Format

Selecting the appropriate image format can affect your website’s loading speed, image quality, and compatibility across various devices. In this section, we will cover:

  • The different types of image formats and their pros and cons
  • Choosing the right file type based on the image content and usage
  • The impact of file compression on image quality and loading speed

1. The different types of image formats and their pros and cons: There are three types of image formats commonly used: JPEG, PNG, and GIF. Each of these formats has its advantages and disadvantages. JPEG is best for photographs, PNG for illustrations, and GIF for animations.

2. Choosing the right file type based on the image content and usage: Choosing the right file type based on the image content and usage is essential. JPEG is best for images with lots of detail, while PNG is best for images with transparent backgrounds. GIF is best for animations.

3. The impact of file compression on image quality and loading speed: File compression involves reducing an image file size without compromising its quality. Compression has a significant impact on image quality and loading speed. Using compression software helps maintain image quality while reducing file size, significantly improving website performance.

How to optimize the images on your website?

1. Choose the right image file type

When you’ve created an image, you have to choose a file type to save it as. There are many different options to choose from; here are a few of the most common:

  • JPEG – JPEGs will work for most of the images on your site, with the exception of any images that have a transparent background. JPEGs are ideal because they allow for higher quality images and smaller file sizes, but fall short when it comes to things like logos or line drawings. With JPEGs, some file data may be lost in compression; although, the loss is not typically noticeable.
  • PNG – When images don’t have a lot of color, are transparent or have a lot of text, PNGs are ideal. PNGs, however, will require larger file sizes.
  • GIF – GIFs can compress images into smaller file sizes, much like JPEGs, but the color range on GIFs is limited, making it a poor choice for most photography. However, GIFs can be great for animation.
  • TIFF – In terms of quality, TIFFs are king. However, it comes at the cost of size, as they are uncompressed and therefore much, much larger.
  • WebP – WebP is a relatively new image format that offers both smaller file sizes and higher quality than JPEGs.
  • AVIF – AVIF is a new image format that is similar to WebP but with better compression, meaning it can offer even smaller file sizes at the same level of quality.

2. Use a keyword to name your images

Most people don’t give a second thought to what the file names for their images are, but it turns out that it matters a lot more than you might think.

Did you know that Google will actually crawl the file names of your images? Make the names of your images descriptive and keyword-rich (but not spammy!).

If you leave the default image name — dsc1938473.jpg, for example — it’s a missed SEO opportunity. Instead, if the image is of a pair of women’s shoes, for example, choose something like pink-platform-shoes.jpg.

3. Resize your images

Large images can slow your website down like crazy, and what’s more is that it’s entirely unnecessary to have an image that’s larger than the maximum size your site will allow for. And, since most people won’t wait longer than three seconds for a website to load, site speed is of the utmost importance.

Resizing and compressing — which reduces the file size while preserving the quality of the image — your images will prevent them from slowing your site down.

4. Optimize the alt image tags

The alt image tags, also called the alt attributes, are the text alternative to images when they fail to load on your website, but otherwise, they do not appear on your website.

Alt image tags used to tell people who have visual impairments what your images are, and they’re used by search engines to determine ranking in image searches, as well as a website’s organic ranking as a whole.

Suffice it to say, optimizing alt image tags is important. Here are a few rules to keep in mind to help you get it right:

  • Use plain, descriptive language in your alt image tags, much like when you renamed the image file
  • If the image is of a product with a serial number or model number, include it in the alt image tag
  • If you can do so naturally, include a relevant keyword in your alt image tag. But, don’t force or overly stuff keywords into your tags.

5. Use decorative images wisely

Decorative images are images that are solely used for aesthetics and don’t add any understanding of the page or the content; think background images, borders, spacers, etc.

Although these images can make your website look a whole lot better looking, they can also make it a whole lot slower if you’re not careful.

Make sure that you always check and minimize the file size for all of the decorative images on your website. Background images, especially, look great but can have large file sizes.

Compress these images as much as possible without sacrificing quality. You could also minimize the size of a background image by cutting out the middle and making it transparent or a flat color.

Never add alt attributes to the decorative images on your website. Believe it or not, there is such a thing as over-optimization, and search engines could penalize you for it.
