I certainly do \u2013 it was one of the most time-consuming parts of my content creation process. But thanks to AI, this process is now a lot easier. I\u2019ve been impressed by how much AI can help streamline website management, especially when it comes to accessibility and SEO tasks. That\u2019s why I\u2019ve dedicated a lot of time to testing various AI-powered alt text generators on WordPress websites. In this guide, I\u2019ll show you the best way to automatically generate alt text using AI. I\u2019ve done all the heavy lifting \u2013 testing accuracy, comparing results, and identifying the best options \u2013 so you can choose the right solution for your website.The Benefits of Using AI for Generating Image Alt TextAdding alt text to every image on your website can feel like a never-ending task. Even if you\u2019re using tools like ChatGPT to write the alt text for you, you\u2019ll still need to manually copy and paste the content. Luckily, AI-powered tools can automate this entire process and allow you to control everything from your WordPress dashboard. Here\u2019s why using AI for alt text generation in WordPress can be helpful:\u2705 Saves Time \u2013 No more writing alt text for every single image. AI can generate descriptions in seconds, freeing up your time for more important tasks.\u2705 Boosts SEO \u2013 AI helps you create descriptive alt text with relevant keywords, which search engines love. This can help your images rank higher in search results.\u2705 Improves Accessibility \u2013 AI-generated alt text makes your site more inclusive by providing meaningful descriptions for visually impaired users.\u2705 Handles Large Image Libraries \u2013 If you have hundreds (or thousands) of images, AI can process them in bulk, making optimization much easier.\u2705 Maintains Consistency \u2013 AI follows a structured approach, ensuring all images have clear and uniform descriptions across your website.By using AI tools for alt text generation, you can improve your website\u2019s accessibility, SEO, and overall efficiency, all without the extra manual work.Having said that, let\u2019s take a look at how to easily generate alt text for images with AI. Method 1: Use AltText.AI to Generate Alt Text for Images (Premium Plugin + Free Trial)If you are looking for high-quality alt text for your images and have the budget to invest in a premium plugin, then I recommend this method. AltText.ai is a powerful AI image alt text generator built for bloggers, small business owners, and website owners. It works in up to 130 languages and generates alt text in just seconds. It comes with a free trial that lets you generate alt text for up to 25 images. After that, you can continue with a paid plan starting at just $5 for 100 image credits, where generating alt text for 1 image uses 1 credit. This makes it an affordable option for anyone managing a media-rich website. First, you need to visit the AltText.ai website and click the \u2018Start Free Trial\u2019 button.This will take you to a new screen, where you can create your free account by giving your email address, name, and password.Once you do that, just click the \u2018Sign up\u2019 button.AltText.ai will now create your free account and take you to your dashboard.From here, head to the \u2018Account\u2019 page from the top and switch to the \u2018API Keys\u2019 section. Go ahead and click the \u2018+ New API Key\u2019 button.Next, you have to type a name for the API key you plan to create. This name won\u2019t be available publicly and is only for your identification.Then, click the \u2018Create\u2019 button.The tool will automatically create an API key for you. For now, click the \u2018Copy\u2019 button next to the key and store it somewhere safe. You\u2019ll need it later to use the tool.Next, head to your WordPress dashboard to install and activate the Alt Text AI\u00a0plugin. It is a free connector plugin that integrates the AI tool with WordPress seamlessly.For step-by-step instructions, see this tutorial on how to install a WordPress plugin.Upon plugin activation, visit the AltText.ai \u00bb Settings page and add your API key in the \u2018API Key\u2019 field. You can also choose your preferred language for alt text generation.After that, pick a writing style for your alt text from the dropdown menu. You can choose between elaborate, concise, matter-of-fact, standard, and terse.You can also use AltText.ai to generate image titles, captions, and descriptions. To do this, just check these options in the \u2018When alt text is generated for an image\u2019 section.After that, check the \u2018Automatically generate alt text with AltText.ai\u2019 option so the tool will automatically generate alt text whenever you upload an image to the media library.Next, you have to scroll down and check the \u2018Generate alt text using focus keyphrases, if present\u2019 option if you want the AI tool to use SEO phrases in alt text. Keep in mind that you\u2019ll also need to add a focus keyword using an SEO plugin for this feature to work. For details, you can check out this guide on how to use a focus keyphrase in WordPress.Similarly, check the \u2018Use post title as keywords if SEO keywords not found from plugins\u2019 box so the tool will use post titles in alt text if you haven\u2019t set a focus keyword. You can then configure the rest of the settings according to your liking. Once you are done, just click the \u2018Save Changes\u2019 button.Now, you need to open the block editor and upload an image using the \u2018Image\u2019 block.This will open the \u2018Select or Upload Media\u2019 prompt, where you have to click the \u2018Update Alt Text\u2019 button. You can also check the \u2018Add SEO Keywords\u2019 option to add them to your alt text.You can also generate alt text for already uploaded images by visiting the Media \u00bb Library page and clicking on an image.Once the \u2018Attachment details\u2019 page opens up, check the \u2018Add SEO Keywords\u2019 box and add the keywords you want the tool to prioritize. Then, click the \u2018Update Alt Text\u2019 button to create alt text for your image.You can now repeat the process for all your images.However, if you\u2019re looking to save some time, then the plugin also allows bulk generation for alt text. To do this, head over to the AltText.ai \u00bb Bulk Generate page from the WordPress dashboard.At the top, you will see the total number of images along with how many are missing alt text. You can scroll down from here.Then, if you want to overwrite existing alt text, check the \u2018Include images that already have alt text\u2019 option. This ensures AI-generated descriptions replace any previous alt text.Similarly, if you want to process only images attached to posts, check the \u2018Only process images that are attached to posts\u2019 box. This makes the plugin focus on optimizing images used in your content.Once you\u2019ve selected your preferences, click the \u2018Generate Alt Text\u2019 button to start the process.The AI tool will take about 3-5 minutes to add all the alt text, depending on the number of images, and you will see a success message upon completion.Go ahead and click the \u2018Done\u2019 button to be redirected to the Bulk Generate page. That\u2019s all you need to do!Method 2: Use a Free AI Plugin to Generate Alt Text, Title, and Caption for ImagesIf you are looking for a free AI image alt text generator that can also create image titles and captions, then I recommend this method instead. The free AI for SEO plugin offers a built-in way to improve your image SEO without leaving your site or paying for additional tools.Important: The plugin only provides 5 free AI credits every day. If you go over that limit, then you\u2019ll need to upgrade to a paid plan to continue using the AI features.First, you need to install and activate the AI for SEO plugin. For details, see this step-by-step tutorial on how to install a WordPress plugin.Upon activation, visit the AI for SEO page from the WordPress dashboard and switch to the \u2018Settings\u2019 tab from the left column. Then, scroll down to the \u2018Media attributes\u2019 section.Here, you can choose whether you want the AI to generate alt text, captions, titles, and descriptions for your images. If you prefer not to use a specific feature, then simply uncheck the box next to it. For instance, if you don\u2019t want the AI to generate captions, then just uncheck that box.After that, you can also choose a language for your media attributes from the dropdown menu. This will allow the plugin to generate text in the language used on your website.You can then configure the rest of the settings according to your liking. Finally, click the \u2018Save Changes\u2019 button to store them.Now, head over to the Media \u00bb Library page from the WordPress dashboard and choose an image you like.This will open the \u2018Attachment Details\u2019 prompt, where you can click the \u2018Generate With AI\u2019 button under the title, caption, alt text, and description fields.Once you do that, the plugin will use AI to generate alt text, caption, title, and description that match your image.If you don\u2019t like the initial results, then you can simply keep clicking the \u2018Generate with AI\u2019 button to get new suggestions. This lets you cycle through different options until you find one that fits better.You can now repeat the process to generate alt text with AI for all your images.Bonus: Optimize Your Image Alt Text with AIOSEOAutomatically generating alt text with AI is just one way to improve the images on your website. I also recommend using an SEO plugin with built-in tools for image SEO.For example, All in One SEO for WordPress (AIOSEO) can optimize the format of alt text on your images. Its Alt Tag feature pulls the existing alt text from your media library and allows you to control its formatting with your website title or other metadata.This feature can help with branding and SEO by making your images more relevant to search engines. Just keep in mind that AIOSEO doesn\u2019t actually generate the alt text for you. Another great feature is AIOSEO\u2019s image sitemap generation, which includes XML sitemaps. This helps search engines index your images correctly, increasing the chances of them appearing in Google Image Search.To get started, just see adrimadise\u00f1o\u2019s ultimate guide to WordPress image SEO.I hope this article helped you learn how to generate alt text for images using AI.
