A quick overview

BIALTY also allowed, through a Post META Box, the personalización manual en sus páginas, con el uso de ALT TEXT distintos a los utilizados con Yoast o títulos de página.

BIALTY operates in automatic mode. Una vez installed, estará activo en all las pages de su sitio, retroactivamente y para contenido futuro. Ya no tienes que pensar en tus Alt Texts.

Also compatible with: TinyMCE, SiteOrigin Page Builder, Elementor Page Builder, Gutenberg and more…


The BIALTY complements are translated and available in: inglés, francés: francés, ruso: Руссɤɢɣ, portugués: portugués, español: español, alemán: alemán.

¿Por qué deberías optimize los alternativos textos of your imagen? Porque más del 20% de las consultas de búsqueda is realized in Google Imágenes. Consult here

Alternate text (alt text) is a text description that can be aggregated with the HTML tag of an image on a web page. Se utiliza cuando la imagen de la web page no se puede mostrar, en cuyo caso se muestra el texto Alt en su lugar. También se muestra cuando un usuario pasa el mouse sobre la imagen.

Unfortunately, the ALT atributo is a critical paso that a menudo is passed por alto.

Have you ever been in the situation where you have hundreds or thousands of images on your website without any alt tag? You know by definition that this will somehow hurt your Google rankings, especially when YOAST SEO keeps reminding you that “Not all images on this page contain ALT attributes with the word- focus key”. This can be a lost opportunity for higher search engine rankings.

Of course, you can add these alts manually (and spend dozens of hours doing it) or use other WordPress plugins by automatically adding the product/page/post title or image name/title by as ALT texts (with ‘_’ which aren’t SEO-friendly, by the way), but those still won’t be the best ALT attributes to add to your images and Yoast will still show that orange/red dot to you reminding you that you DID NOT do the job as you should. And for good reason, because Alt tags reinforce the message of your articles to search engine spiders (which cannot determine the content of images and must rely on Alt text to determine their content) and improve 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 possibly 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 automatically add it to the HTML tags of your page image: . Simple & effective…

FYI, Google’s article on images has a title “Creating great alt text”. This is no coincidence, as Google places a relatively high value on alt text in determining not only what is in the image, but also what the surrounding text is about. (https://support.google.com/webmasters/answer/114016?hl=en)

How it works?

Install BIALTY on your website, select your preferred option either “Only YOAST Focus Keyword” or “YOAST Focus Keyword + Page/post/product title”, after saving, BIALTY will add ALT Texts to all images, on each page, according to your optimizing.

Then, simply forget about it…

Best practices?

The text (keyword) should be kept short to maximize its impact. Shorter alt texts (thus keywords) are also more likely to be indexed by Google and the other major online search engines in a more efficient manner (please read our FAQ for more info)

What purpose do alt tags serve?

Search engines and other crawler bots cannot interpret/understand images, but images can play a crucial part in how people interpret a particular web page. Alt text solve for this by providing text which is read by the search engines.

When Google bot or other search engine crawlers inspect a page, images with properly formatted alt text contribute to how the page is indexed and where it ranks on SERP.

Alt text or Alt tag ?

When you think of image alt text, the term that may immediately come to mind is “alt tag”. Alt tag is actually a misnomer and doesn’t exist at all. Because alt text, or alternative text, is the alternate text attribute of the image tag.

This is where communication in the SEO world can get dicey, because it may be known as one thing that just about everyone knows what an alt tag is, but in reality, it is entirely different.

Alternative text (or Alt text) is mainly used by screen readers for the blind to decipher what an image is about. It lets you specify an image description that is fed through an audio-based prompter that tells blind people what is currently on the page as they are scrolling through the page.

According to W3C Accessibility Guidelines, for code to be considered W3C-valid, it is important to include both image alt text and image title text in the image for important images on the page.

Why is Alt Text Important?

Google’s article about images has a heading “Use descriptive alt text”. This is no coincidence because Google places a relatively high value on alt text to determine not only what is on the image but also how it relates to the surrounding text.

Using alt text (or Alt attribute) on your images can make for a better user experience, but it may also help earn you both explicit and implicit SEO benefits. Along with implementing image title and file naming best practices, including alt attribute will also contribute to image SEO.

Today, Google’s search engine results pages (SERPs) deliver just as many image results as they do text-based results. So, one of the most important things image alt text can do for you is turn your images into hyperlinked search results — giving your website yet another way to receive organic visitors.

While search engine image recognition technology has vastly improved over the years, search crawlers still can’t “see” the images on a website page like we can, so it’s not wise to leave the interpretation solely in their hands. If they don’t understand, or get it wrong, it’s possible you could either rank for unintended keywords or miss out on ranking altogether.

About Google’s Image Recommendations ?

To boost your content’s visibility in Google Images, focus on the user by providing a great user experience: make pages primarily for users, not for search engines. Here are some tips:

  • Provide good context: Make sure that your visual content is relevant to the topic of the page. We suggest that you display images only where they add original value to the page. We particularly discourage pages where neither the images or the text are original content.

  • Optimize placement: Whenever possible, place images near relevant text. When it makes sense, consider placing the most important image near the top of the page.

  • Don’t embed important text inside images: Avoid embedding text in images, especially 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, provide alt text for images.

  • Create informative and high quality sites: Good content on your webpage is just as important 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 page content quality when ranking images.

  • Create device-friendly sites: Users search on Google Images more from mobile than on desktop. For this reason, it is important that you design your site for all device types and sizes. Use the mobile friendly testing tool to test how well your pages work on mobile devices, and get feedback on what needs to be fixed.

  • Create 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.

Installing manually

  1. Unzip all files to the /wp-content/plugins/bulk-image-alt-text-with-yoast directory
  2. Log into WordPress admin and activate the ‘BIALTY – Bulk Image Alt Text (Alt tag, Alt Attribute) with Yoast SEO + WooCommerce’ plugin through the ‘Plugins’ menu
  3. Go to “Settings > Bulk Image Alt Text” in the left-hand menu to start work on it.


What is alt text?

Alt text (alternative text), also known as “alt attributes”, “alt descriptions,” and technically incorrectly as “alt tags,” are used within an HTML code to describe the appearance and function of an image on a page.

How to use Alt text:

• Adding alternative text to photos is first and foremost a principle of web accessibility. Visually impaired users using screen readers will be read an alt attribute to better understand an on-page image. • Alt tags will be displayed in place of an image if an image file cannot be loaded. • Alt tags provide better image context/descriptions to search engine crawlers, helping them to index an image properly.

Appropriate length?

Google seemed to count the first 16 words in the ALT tag and interestingly in the snippet Google uses, it does seem to completely cut off the rest of the ALT and from the 17th word. Having 16 words to work with might prove very useful if you are using ALT tags to describe more complex images. There is potentially plenty of available space to describe images properly for accessibility purposes AND SEO impact.

How Image Alt Tags and Meta Data Help SEO

Optimizing your images for SEO helps crawlers better index your web pages, which in turn can give you a rankings boost because it can make the page more relevant to users. Let’s say a searcher needs plumber repairs for a clogged bathroom drain. Google has to choose between two web pages from different companies, both of which have equal ranking factors. As the crawler reads through the first page, it doesn’t identify any image alt-tags, therefore, it assumes the images (if there are any) do not add page-specific value. On the second page, however, the crawler locates five images, each one with a full description of what the image is showing. All five images’ alt tags supplement the rest of the text on the page. Since Google is all about spitting out the results you’ll most likely jive with, it’s going to go with the article that it thinks is more relevant.
