Common Mistakes to Avoid in Image Optimisation for SEO

Image Optimisation for SEO

In the fast-paced world of digital marketing, image optimisation plays a crucial role in enhancing the overall user experience and improving a website’s search engine ranking. While it might seem like a straightforward task, there are common mistakes that many website owners make when it comes to image optimisation for SEO. In this blog post, we’ll unveil these secrets and provide valuable insights on how to avoid them.

Mistakes to Avoid in Image Optimisation

Neglecting Image Compression

One of the most common mistakes is neglecting image compression. Large image file sizes can significantly slow down your website, leading to a poor user experience and negatively impacting your SEO ranking. Always compress your images without compromising quality to ensure fast loading times.

Ignoring Image Alt Text

Alt text, or alternative text, is used to describe the content of an image. Ignoring this crucial element can be detrimental to your SEO efforts. Search engines rely on alt text to understand what an image represents, and it also improves accessibility for users with visual impairments. Be descriptive and concise in your alt text to provide meaningful information.

Using Generic File Names

Uploading images with generic file names like “IMG001” or “photo.jpg” is a missed opportunity for SEO. Rename your image files with descriptive, keyword-rich names that reflect the content of the image. This helps search engines understand the context and relevance of the images on your site.

Overlooking Image Sitemap Submission

Many website owners forget to include images in their sitemap, which can impact search engine indexing. Create a dedicated image sitemap and submit it to search engines through your Google Search Console. This ensures that search engines recognise and index your images appropriately.

Neglecting Responsive Design

In the era of mobile-first indexing, neglecting responsive design can lead to a poor user experience on mobile devices. Ensure that your images are optimised for various screen sises and resolutions to cater to users accessing your site from different devices.

Forgetting About Lazy Loading

Implementing lazy loading is a smart strategy to enhance website performance. This technique delays the loading of off-screen images, reducing the initial page load time. However, some webmasters forget to implement lazy loading, resulting in slower load times and a potential negative impact on SEO.

Using High-Resolution Images Unnecessarily

While high-resolution images are essential for certain contexts, using them unnecessarily across your entire website can lead to slower loading times. Optimise images based on the required resolution for each page to strike a balance between quality and performance.


Image optimisation is a crucial aspect of SEO that should not be overlooked. By avoiding these common mistakes, you can ensure that your website is well-optimised for search engines, providing a seamless and engaging experience for your users. Keep these tips in mind as you fine-tune your image optimisation strategy, and watch your website climb the ranks in search engine results.
