Best techniques for optimising images for search engines ChatGPT ChatGPT Optimising images for search engines is essential for improving your website's visibility in image search results and overall SEO. Here are some of the best techniques for optimising images for search engines:

Use Descriptive Filenames : Rename image files with descriptive and relevant keywords before uploading them to your website. Avoid generic filenames like "image123.jpg" and use descriptive filenames that accurately describe the image's content.

Optimise Image Size and Format : Compress images to reduce file size without sacrificing quality. Smaller file sizes improve page load times, which is a ranking factor for search engines. Use appropriate image formats such as JPEG for photographs and PNG for images with transparency.

Add Descriptive Alt Text: Include descriptive alt text (alternative text) for each image to provide context to search engines and screen readers. Alt text should accurately describe the image's content and include relevant keywords when appropriate. Alt text also improves accessibility for users with visual impairments.

Optimise Image Titles : Use descriptive and keyword-rich titles for images. Image titles are displayed when users hover over a photo, so ensure they provide additional context and relevance to the image content.

Include Captions and Context : Whenever possible, include captions or surrounding text that provide additional context to the images on your website. This helps search engines understand the relevance of the photos to the surrounding content and improves their chances of ranking well in search results.

Utilise Image Sitemaps : Create and submit an image sitemap to search engines to help them discover and index the images on your website more efficiently. An image sitemap provides additional information about each image, such as its URL, title, caption, and license information.

Implement Structured Data Markup : Use schema.org markup to provide search engines additional context about your images. Structured data markup can help search engines understand the content and context of your photos, leading to improved visibility in search results and potential inclusion in rich snippets or image carousels.

Optimise Image Dimensions : Specify images' width and height attributes in your HTML code to help browsers render the page more quickly. This can improve page load times, user experience, and ranking factors for search engines.

Host Images on Your Domain : Whenever possible, host images on your domain rather than using third-party hosting services. Hosting images on your domain allows you to retain control over the images and ensures search engines properly index them.

Monitor Image Performance : Regularly monitor the performance of your images in search results using tools like Google Search Console—Analyse metrics such as impressions, clicks, and click-through rates to identify opportunities for optimisation and improvement.
