Strategic Use of Images in Search Engine Optimisation

When assessing page structure and layout, there is a subtle yet strategic way to use images in an SEO-friendly manner (beyond ALT tags) that improves your search rank while allowing you to integrate necessary marketing messages. Confused? Let’s look at an example:

Suppose you operate a travel site and want to optimize a given page for the term “Las Vegas hotel.” Additionally, you want to include an enticing marketing message such as “Book now and save 20%!” This tagline, while persuasive, lacks descriptive text critical for SEO. To reconcile this, you can place the tagline within an image and use the key phrase “Las Vegas hotel” in a header tag. This approach emphasises the desired term while providing a marketing opportunity without compromising keyword consistency.

Images are an excellent medium for embedding marketing messages that may not include necessary keywords and phrases. By leveraging this technique, you ensure that descriptive text is indexed while marketing jargon is visually appealing yet unobtrusive to SEO efforts. The combination of keyword-rich content and compelling messaging satisfies both strategic needs.

Now, let’s delve deeper into the strategic use of images in SEO:

1. Optimising Image File Names

Before even uploading images to your site, optimising the file names is crucial. Instead of generic names like “IMG_1234.jpg,” use descriptive names like “las-vegas-hotel-book-now.jpg.” This helps search engines understand the content of your images, contributing to better indexing and relevancy.

2. Utilizing Captions and Surrounding Text

Captions are among the most read pieces of content on a page. Including keywords in your captions can enhance SEO. Similarly, the text surrounding images should be relevant and keyword-rich. Search engines use this context to determine the image’s relevance to the page content.

3. Implementing Structured Data

Structured data, or schema markup, helps search engines understand the content of your images. By adding schema markup to your images, you can provide search engines with detailed information about the image content, improving the chances of your images appearing in search results.

4. Ensuring Mobile Optimization

With mobile searches surpassing desktop, ensuring your images are optimised for mobile devices is essential. Responsive images that adjust to different screen sizes enhance user experience and positively impact SEO rankings. Modern image formats like WebP can reduce load times, improving SEO.

5. Leveraging Image Sitemaps

Creating an image sitemap helps search engines find and index your images more effectively. This is particularly useful for large sites with numerous images. An image sitemap provides search engines with additional information about your images, improving their likelihood of appearing in image search results.

6. Using Descriptive ALT Text

While ALT tags are a common SEO practice, making them descriptive and relevant is important. ALT text should describe the image and incorporate relevant keywords naturally. This enhances accessibility and provides search engines with additional context.

7. Balancing SEO and User Experience

While optimising images for SEO is important, it should not come at the expense of user experience. Ensure that images are high-quality and relevant and enhance the page’s overall content. Striking a balance between SEO and user experience will create a more engaging and effective webpage.

Conclusion

Strategically using images in SEO involves more than just ALT tags. By optimising file names, utilising captions, implementing structured data, ensuring mobile optimisation, leveraging image sitemaps, and balancing SEO with user experience, you can significantly enhance your site’s search engine performance. Images are a powerful tool in your SEO arsenal, allowing you to convey marketing messages and improve rankings simultaneously. Through thoughtful integration and optimisation, images can play a pivotal role in your overall SEO strategy, driving traffic and engagement to your site.
