The Role of Alt Text in Image SEO
You may not realise how you are negatively impacting your SEO efforts by not adding alt text when adding images to your website. When you add alt text for images, you improve your SEO image optimisation.
Images provide value to your website. You can lean on visuals as complete concepts or to capture your visitors attention, breaking up blocks of text, helping to keep your website visitors engaged for longer. At the same time, images are also very important to SEO. More people are using visuals to search the internet than ever before, meaning if you are not optimising your images for SEO using alt text, you could be missing out on organic traffic.
Alt text, or alternative text, is copy that is added to an image for those with visual impairments or when your website doesn't load completely. It helps screen readers, enabling visitors to understand the context of your images. Search engine also cannot see visual information, relying on alt text on the images as valuable information about what the image contains and how it blends in with the content.
Alt text improves accessibility for people who cannot see the images on your website, improving accessibility and user experience (UX). Accessibility is important to Google, promoting a positive user experience. It also helps Google and other search engines understand the images on your page and what they are about.
Now that you have some understanding on why alt text is important for your website visitors and search engines, lets look how alt text plays a role in your SEO image optimisation strategy. Google places value in alt text, not only to determine what is on your page, but how it relates to the surrounding content.
When it comes to adding alt text to your images, it's important to write informative and useful content including your targeted keywords that relates to the content on your page.
The Genie Crawl team recommend when it comes to writing alt text you want to be specific. A few words are enough, but they should be no more than one hundred and twenty five characters. Keep it concise and to the point, while offering valuable information, using your targeted keyword.
When it comes to alt text, you only have one hundred and twenty five characters to work with, so don't waste space introducing each image. Avoid the fluff, getting to the point. You don't have to start each alt text with “This is an image of,” for example.
You should always incorporate your target keywords into your alt text, but do not overstuff the keywords. Try and include your keywords naturally within the text, ideally at the start of the text.
The aim of alt text is to ensure your images are accessible to all your website visitors, including those that are visually impaired, therefore the text you add should be about the image itself. You do not have to repeat your existing content.
A decorative image has no function, this can be a graphic divider or a background image. These images do not offer any value to your website visitors and therefore they do not need a alt text included. In fact, adding alt text to background images can clutter your website, resulting in a poor user experience.
Alt text is valuable for image SEO, helping your website visitors and search engines understand what your image is. Remember, search engines don't have eyes, they cannot visualise the image, which is why alt text is essential to your image SEO success.
