Why should you optimize your image Alt Texts? Because more than 20% of search queries are made on Google Images. Check here

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 in the Web page cannot be displayed, in which case the Alt text is shown instead. It is also displayed when a user mouses over the image.

Unfortunately, the ALT attribute is a critical step that is often overlooked.

Have you ever been in the situation where you have hundreds or thousands of images on your website without any alt tags? You know by definition that it will hurt 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 lost opportunity for better rankings on search engines.

Of course, you could add these alts tags manually (and spend dozens of hours doing it) or use other WordPress plugins auto-adding 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 on the image but also the topic of the surrounding text.

How does it work?

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 optimization.

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)

Perguntas frequentes

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.
