Practical Tips for Optimising Images for SEO

SEO For Images

As the world of online marketing continues to evolve, search engine optimisation (SEO) remains a crucial element in driving organic traffic to websites. While many businesses focus on optimising their website’s content and structure, they often overlook the importance of image optimisation.

Images can greatly enhance user experience and attract visitors to a website, but they can also slow down load times if not optimised properly. Therefore, it is essential for businesses to optimise their images for SEO.

Optimising images for SEO involves several techniques that aim to improve visibility and ranking in search engine results pages (SERPs). These techniques include choosing the right format, compressing images without sacrificing quality, customising file names, writing SEO-friendly alt text, and optimising page titles and descriptions.

By implementing these practical tips, businesses can increase their chances of ranking higher in SERPs and attracting more organic traffic to their website. In this article, we will delve into each of these techniques in detail and provide actionable tips for optimising your images for SEO.

Choose The Right Format

The selection of an appropriate format for images is a crucial factor in optimising them for SEO, as it directly affects their file size and quality. When deciding which format to use, one must consider the trade-off between size and quality. Generally speaking, smaller file sizes are better for website loading speed; however, if too much compression is applied to an image, its quality

will suffer. Therefore, choosing the right balance between compression and image clarity is important.

Another consideration when choosing an image format is browser compatibility. Some formats are not supported by all web browsers or devices, which can cause issues with how the image appears on different screens. Additionally, transparency support should also be taken into account when selecting a format. For images that require transparent backgrounds or layers (such as logos), PNG format would be more suitable than JPEG or GIF formats.

Other factors that need to be considered include image resolution and color depth – higher resolutions are generally better for larger images while lower resolutions can suffice for smaller images like thumbnails or icons; similarly, greater color depth provides more vibrant colors but also results in larger file sizes.

In summary, the selection of an appropriate image format involves finding the right balance between size and quality while considering other factors such as browser compatibility and transparency support.

Compress Your Images

Utilising compression techniques can significantly reduce the size of image files, making them more web-friendly. This is crucial for website loading speed and user experience as it reduces the time it takes to load pages, especially on mobile devices with slower internet connections.

Compressed images also consume less bandwidth, which is essential for those who have limited data plans or slow internet speeds. However, compressing images should be done carefully to ensure that image quality remains high.

Online tools such as TinyPNG, JPEG Optimiser, and are available to help reduce the size of images without compromising image quality. It is essential to experiment with different settings while compressing images to find a balance between file size reduction and maintaining acceptable image quality.

By doing so, websites can load faster without sacrificing the aesthetic appeal of their content, resulting in an overall better user experience.

Customise Image File Names

Customising image file names is an effective way to enhance website accessibility and improve user experience. The importance of naming conventions should not be underestimated as it can greatly impact the visibility of images on search engines.

Image file names should accurately describe the content of the image and include relevant keywords for better SEO results. Keyword research can also play a crucial role in customising image file names. Identifying relevant keywords that users might use when searching for a particular image can help increase its visibility on search engine result pages (SERPs).

However, it is important to avoid stuffing too many keywords into the file name as this may harm SEO rankings rather than improve them. Additionally, considerations such as image size, metadata, and sitemaps should also be taken into account when customising image file names to ensure optimal performance on search engines.

Write SEO-Friendly Alt Text

A crucial aspect of enhancing website accessibility and improving user experience is crafting alt text that is optimised for search engine rankings. Alt text, or alternative text, serves as a description of an image in case it can’t be displayed on a webpage. It also plays a significant role in helping search engines understand the content of an image and its relevance to a particular query.

To write effective alt text, it’s essential to follow alt text best practices. Firstly, keep your descriptions concise and relevant to the image context. Avoid stuffing keywords into your alt text as this will not only irritate users but may also result in penalties from search engines due to keyword spamming.

Secondly, use descriptive language that accurately represents the image’s content while incorporating relevant keywords within natural-sounding phrases. Lastly, ensure you don’t exceed 125 characters when writing alt text as longer descriptions may get truncated by assistive technologies like screen readers or voice assistants.

Failure to provide proper alternative texts may harm SEO rankings and negatively impact the overall user experience on your website. Therefore, it’s crucial to invest time in crafting well-written and informative descriptions for all images on your site.

Optimise Your Page Title & Description

Optimising the page title and description is a crucial aspect of enhancing website visibility. The page title is the text that appears at the top of your browser tab, while the description is a brief summary of what your webpage or article is about. These elements are essential in improving click-through rates (CTR) and driving traffic to your site.

To ensure that they are effective in attracting user attention, you need to use keywords that accurately reflect the content on your page. This will help search engines understand what your content is about, making it easier for users to find.

Apart from using keywords, you should also consider length when optimising your titles and descriptions. Keep them concise but informative as users are more likely to click on titles and descriptions that clearly communicate what they can expect from clicking through to your website or article. Additionally, adding branding elements like logos or icons can help build brand recognition and make it easier for users to identify with your content.

It’s also important to A/B test different variations of titles and descriptions to determine which work best in terms of CTR and engagement rates. By implementing these practical tips, you can improve the chances of getting more clicks and boosting overall website visibility.


The truth is, optimising images for SEO is not rocket science. With a few practical tips, you can improve your website’s visibility on search engines and attract more traffic to your site.

Firstly, choosing the right format for your images can make a significant difference in how they appear on your webpage. JPEGs are ideal for photographs while PNGs are better suited for graphics and logos.

Secondly, compressing your images without sacrificing quality is crucial as large image files can slow down your page loading speed. Customising image file names with relevant keywords gives further context to search engines about what the image represents. Writing SEO-friendly alt text helps visually-impaired users understand the content of the image and improves accessibility.

Lastly, optimising your page title and description with relevant keywords will help search engines understand what the page is all about.

In conclusion, by following these practical tips in optimising images for SEO, you’ll be able to create a user-friendly website that attracts more traffic while also improving its accessibility and visibility on search engines. Remember that every little detail counts when it comes to online marketing!
