详情介绍:

Bialty automatically adds ALT TEXTs to your images from page/article/product titles (with Woocommerce for online shops) or Yoast's Focus Keywords, either separately or combined (depending on your needs). BIALTY also allows, through a Post META Box, manual customization on your pages, using ALT TEXTs different from those used with Yoast or Rank Math or page titles. BIALTY operates in automatic mode. Once installed, it will be active on all pages of your site, both retroactively and for future content. You no longer need to worry about your Alt Texts. It's also compatible with: TinyMCE, Page Builder by SiteOrigin, Elementor Page Builder, Gutenberg and more… About the PRO feature: SUPPORTED IN 6 LANGUAGES BIALTY plugins are translated and available in: English, French – Français, Russian –Руссɤɢɣ, Portuguese – Português, Spanish – Español, German – Deutsch 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 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. (https://support.google.com/webmasters/answer/114016?hl=en) 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? Google's article 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:

安装:

Installing manually
  1. Unzip all files to the /wp-content/plugins/bulk-image-alt-text-with-yoast directory

  3. Go to "Settings > Bulk Image Alt Text" in the left-hand menu to start work on it.

常见问题:

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 does Bialty work?

Bialty uses WordPress hooks and filters to modify image alt text in real-time when pages load. Unlike traditional bulk modification plugins, it doesn't make any permanent changes to your database or Media Library. This means you can safely test it on your website, and if you ever disable the plugin, everything returns to its original state.

Will Bialty slow down my website?

No, Bialty is designed to be lightweight and efficient. Since it processes one page at a time as visitors load them, rather than modifying your entire database at once, there's no significant impact on server performance or page load times.

Can Bialty handle large numbers of images?

Yes! Because Bialty processes images on-the-fly, it can handle any number of images without overloading your server. Whether you have 100 or 100,000 images, Bialty will process them efficiently as each page loads.

What types of images can Bialty modify?

Bialty works with images that appear in your post/page content and WooCommerce products, including featured images, product gallery images, and images within product descriptions or post content. Note that Bialty doesn't modify images in headers, footers, sidebars, or other areas outside standard WordPress content areas.

Can I limit Bialty to work only on WooCommerce products?

Yes! In the plugin settings, you can choose which post types Bialty should work with. You can enable it exclusively for WooCommerce products by unchecking other post types.

What alt text options does Bialty offer?

Bialty provides several pre-defined options for alt text: use post/product title, use Yoast Focus Keyword, use image filename, or custom alt text (set per product/post). You can also choose whether to add alt text only where it's missing or replace all existing alt text.

Do I need to run a bulk update process when I change settings?

No! When you change settings in Bialty, they take effect immediately for all pages as they load. There's no need to run any bulk update process or worry about server load.

What happens if I uninstall Bialty?

Since Bialty doesn't modify your database, uninstalling it simply returns your alt text to its original state. This makes it completely safe to test on your live site.

Can I use custom phrases in my alt text?

Currently, Bialty uses predefined options for alt text. While you can set custom alt text for individual products/posts, automatic addition of custom phrases before or after the main alt text is not yet available. We're considering this feature for future releases.

Does Bialty work with page builders?

Yes, Bialty works with major page builders and WordPress themes. As long as the page builder uses standard WordPress methods to display content, Bialty will modify the alt text as expected.

What about multilingual websites?

Bialty is compatible with multilingual websites and will apply alt text based on your settings regardless of the language. It works with popular translation plugins like WPML and Polylang.

Will Bialty affect my SEO?

Bialty can positively impact your SEO by ensuring all your images have relevant alt text. Since it can use your post titles or Yoast Focus Keywords, the alt text will be naturally optimized for your target keywords while remaining descriptive and useful.

How can I test if Bialty is working?

View your page source or inspect an image element, check the alt text before activating Bialty, enable Bialty with your desired settings, then refresh the page and check the alt text again. You should see your chosen alt text format applied to the images.

My images don't seem to be updating. What should I check?

If your images aren't updating, verify that you've selected the correct post types in Bialty settings, the images are within the main content area (not in widgets, headers, or custom sections), your theme uses standard WordPress methods to display content, and you're checking a fresh page load (not a cached version).
