Why should you optimize your image Alt Texts? Because more than 20% of search queries are made on Google Images. Check <a href="https://sparktoro.com/blog/new-jumpshot-2018-data-where-searches-happen-on-the-web-google-amazon-facebook-beyond/" rel="nofollow ugc">here</a>
Alternate text (Alt text) is a text description that can be added to an image’s HTML tag on a web page. It is used when the image on the web page cannot be displayed, in which case the Alt text is shown instead. It is also displayed when a user hovers over the image.
Unfortunately, the ALT attribute is a critical step that is often overlooked.
Have you ever found yourself in a situation where you have hundreds or thousands of images on your website without any alt tags? You know by definition that it will negatively impact your Google ranking in some way, especially when YOAST SEO keeps reminding you that “All the images on this page do not contain ALT attributes with the focus keyword”. This can be a missed opportunity for better rankings on search engines.
Of course, you could add these alt tags manually (and spend dozens of hours doing it) or use other WordPress plugins that auto-add the product/page/post title or image name/title as ALT texts (with “_” which are not SEO-friendly, by the way), but they still won’t be the best ALT attributes to be added to your images and Yoast will keep displaying this orange/red spot reminding you that you HAVE NOT DONE the job as you should. And for good reason, because Alt tags strengthen the message of your articles with search engine spiders (which cannot determine the content of images and must rely on Alt text to determine their contents) and improves the accessibility of your website.
BIALTY is a time-saver because it uses this “Focus Keyword” determined (by you) when optimizing your page/post/product with YOAST SEO (and optionally the page title) as ALT texts for all images contained on this page/post/product. Once your keyword is added in the “Focus keyword” field, after saving your settings, it will add it automatically to the image’s HTML tags of your page. Simple & efficient…
For your information, Google’s article about images has a heading “Create great alt text”. This is no coincidence because Google places a relatively high value on alt text to determine not only what is in the image but also the topic of the surrounding text.

How to use it?
Once you’ve installed BIALTY on your website, you can choose between two options: “Only YOAST Focus Keyword” or “YOAST Focus Keyword + Page/post/product title”. After saving your choice, BIALTY will automatically add ALT Texts to all images on every page, based on your selected optimization. After that, you can simply let it do its work.
What are the recommended practices?
It’s advisable to keep the text (keyword) short to maximize its effectiveness. Shorter alt texts, and thus keywords, are more likely to be efficiently indexed by Google and other major online search engines. For more information, please refer to our FAQ.
What is the role of alt tags?
Search engines and other web crawlers cannot understand images. However, images can significantly influence how people interpret a specific web page. Alt texts address this issue by providing text that can be read by search engines.
When a Google bot or another search engine crawler examines a page, images with properly formatted alt text contribute to the indexing of the page and its ranking on the Search Engine Results Page (SERP).
Alt text or Alt tag?
The term that might immediately come to mind when thinking about image alt text is “alt tag”. However, “alt tag” is a misnomer and doesn’t actually exist. The correct term is alt text, or alternative text, which is the alternate text attribute of the image tag.
This can lead to confusion in SEO communication, as most people are familiar with the term “alt tag”, even though it’s technically incorrect.
Alternative text (or Alt text) is primarily used by screen readers for the visually impaired to understand what an image is about. It allows you to provide an image description that is read out by an audio prompter, informing visually impaired users about the content on the page as they navigate through it.
According to the W3C Accessibility Guidelines, it’s important to include both image alt text and image title text in the image for important images on the page to ensure that the code is W3C-valid.
Why is Alt Text Important?
<a href="https://support.google.com/webmasters/answer/114016?hl=en" rel="nofollow ugc">Google’s article</a> about images includes a section titled “Use descriptive alt text”. This isn’t a coincidence, as Google places a high value on alt text to determine not only the content of the image but also its relation to the surrounding text.
Using alt text (or the Alt attribute) on your images can improve user experience and potentially provide SEO benefits. Along with implementing best practices for image title and file naming, including the alt attribute can also contribute to image SEO.
Currently, Google’s search engine results pages (SERPs) provide as many image results as text-based results. Therefore, one of the key benefits of image alt text is that it can turn your images into hyperlinked search results, providing another avenue for your website to attract organic visitors.
Despite significant improvements in search engine image recognition technology over the years, search crawlers still can’t “see” the images on a website page in the way humans can. Therefore, it’s not advisable to leave the interpretation entirely up to them. If they don’t understand, or get it wrong, you could potentially rank for unintended keywords or miss out on ranking altogether.
About Google’s Image Recommendations?
To enhance the visibility of your content in Google Images, prioritize the user by offering an excellent user experience: design pages primarily for users, not for search engines. Here are some suggestions:
<ul>
<li>Ensure good context: Ensure that your visual content is pertinent to the page’s topic. We recommend displaying images only where they contribute unique value to the page. We strongly advise against pages where neither the images nor the text are original content.</li>
<li>Optimize positioning: When feasible, place images near relevant text. If it makes sense, consider positioning the most important image near the top of the page.</li>
<li>Avoid embedding crucial text within images: Refrain from embedding text in images, particularly important text elements like page headings and menu items, because not all users can access them (and page translation tools won’t work on images). To ensure maximum accessibility of your content, keep text in HTML and provide alt text for images.</li>
<li>Develop informative and high-quality sites: Good content on your webpage is just as crucial as visual content for Google Images – it provides context and makes the result more actionable. Page content may be used to generate a text snippet for the image, and Google considers the quality of the page content when ranking images.</li>
<li>Develop device-friendly sites: Users search on Google Images more from mobile than on desktop. For this reason, it’s important that you design your site to accommodate all device types and sizes. Use the mobile-friendly testing tool to assess how well your pages work on mobile devices, and receive feedback on what needs to be fixed.</li>
<li>Develop a good URL structure for your images: Google uses the URL path as well as the file name to help it understand your images. Consider organizing your image content so that URLs are constructed logically.</li>
</ul>

Bulk Auto Image Alt Text (Alt tag, Alt attribute) optimizer (image SEO)


Ultra misleading title, which is unacceptable. 



Alt text for images attached to WooCommerce products is available only in paid version. The title is misleading, and this "detail" is nowhere to be found in the extremely long plugin description. 



It's ok to have a PAID version, but you have to be clear in the title and description about which features are included in the FREE version, and which on the PAID. This problem is highlighted my multiple users but you still have not updated the plugin description, instead you argue with them in the comments. Please tell the truth about your features and the 1-star reviews will stop coming.


Misleading title, WooCommerce is supported only in paid version


I like what this plugin does (the output is correct), but I wish it wrote to the database rather than run in the front end on every page load. For that reason, I won't be using it myself.



Another good thing is that it lets you choose if you want to overwrite existing values or not. Very important option.


Good plugin, missing 1 function

Two things I absolutely needed this plugin for was identifying and automatically, bulk updating image alt tags for custom post types and top be able to dynamically create the alt text from the filename.

On the "Welcome" splash page, the first thing I see is:

"GET BIALTY PRO TO ENABLE THESE FEATURES:
- Add Post Title or Image Name as Alt Attribute

I thought, "Well, the free version can't do that, but let's see what it can do".

But, then as soon as I'm stepping through the "tour", and I realize that the free version only works on "Post" and "Page", but not on any custom post types. I feel duped.


Although, I wouldn't say that the plugin name is deceptive, it does appear that the marketing department has buried the lede and failed to clearly (not opaquely) indicate that most features WooCommerce sites, News Sites, Directory sites, etc. need are only available in the Pro version.

Also, the fact that there are no YouTube tutorials on how to use this plugin gives one pause.

I've got nothing against premium plugins, but it seems like there is definitely something deceptive about how this plugin is marketed. I cant' quite put my finger on it.

BIALTY Free version doesn't work on custom post types (CPT)

Auto optimize all image alt text (+ Woocommerce ), per page & product, from Yoast SEO / Rank Math optimization settings (keywords).
