How to Optimise Your Images for SEO
Summary: Boost your Google rankings by following our 10 tips for optimising your website images.

In today’s visually-driven digital landscape, knowing how to optimise your images is key to boosting your website’s SEO. Here are our tips to ensure your images not only enrich your website’s content but also enhance its visibility in search results.

 

1. Choose the Right Format

To optimise your images, understanding different image formats is essential. JPEGs are great for photographs due to their compression capabilities, PNGs work well for graphics with fewer colours, and WebP offers a balance of quality and compression. Choosing the right format can significantly impact your page load times, a key factor in SEO.

 

2. Harness the Power of Unique Images

Original images can set your site apart from competitors. Unique images are more engaging than stock photos, can enhance user experience and dwell time, indirectly boosting your Google rankings. Using your own images also avoids copyright issues.

 

3. Descriptive File Names Matter

Since Google can’t ‘read’ images directly (yet), descriptive, keyword-rich file names are essential. A file name DSC_123456 doesn’t tell the search engines a lot! Optimise your images with descriptive image names to aid search engines in understanding and indexing your images more effectively.

 

4. Maximise Alt Text Effectively

Alt text (alternative text) enhances both accessibility and SEO. Provide concise, relevant descriptions of your image, aiding visually impaired users, screen readers, and search engines in understanding the image context.

 

5. Consistent Page Titles and Descriptions

Align your page titles and descriptions with the optimised image content on each web page. This consistency bolsters SEO efficiency.

 

6. Organise your Images Logically

A logical, hierarchical structure for your images on your website can significantly aid search engines in crawling and indexing your pages.

 

7. Compress Images for Speed without losing Quality

Large images can slow down your site, negatively impacting user experience and your search rankings. Tools like Adobe Photoshop, WP Smush, or ImageOptim are great for optimising your images by reducing file size without compromising on quality.

 

8. Specify Image Dimensions

Defining width and height in your image tags ensures that the browser knows the size of the image before loading. This can prevent the page “jumping” (layout shifts) and improve user experience.

 

9. Optimise for Mobile

With the increasing use of mobile devices, ensure your images are responsive. This means the image will scale automatically depending on whether the user is using desktop or mobile. This is crucial for both user experience and SEO.

 

10. Include Images in your sitemaps

Adding images to your sitemap enhances the likelihood of them being indexed by search engines. This step is often overlooked but can be a game-changer in ensuring your images contribute to your site’s visitor numbers.

 

Advanced Tips for optimising your website images

 Leverage Structured Data

Structured data provides additional context to your images, increasing the likelihood of featuring in rich search results.

Adhere to SafeSearch Guidelines

Compliance with Google’s SafeSearch guidelines is imperative for maintaining visibility in specific search results.

Monitor Image Performance

Tools like Google Analytics and Google Search Console are invaluable for tracking image performance and identifying areas for further optimisation.

 

Summary

Image optimization is a multifaceted process that goes beyond just image selection and resizing.

By implementing these tips, SMEs can significantly enhance their website’s SEO performance, leading to better visibility and engagement.
