You can manually check for missing alt attributes in the images that our site auditor reports on your website. Note that our site auditor can report several "Missing Alt Attributes" errors for the same image. This happens when this image appears multiples times across the website.
An alt attribute (often referred to as an "alt tag") provides search engines with descriptive information about an image, which will have an impact on your on-page SEO.
How to find missing alt attributes on your website
Navigate to the SEO --> Site Auditor dashboard module. Click "Missing Alt Attributes" to see more information about which URLs have been flagged with this issue.
The dashboard will show a list of pages containing images with missing alt attributes along with a list of image URLs. Copy the image URL, then click the page URL to open it in a new tab.
Once the new page has opened, open your web browser's developer tools by right-clicking and selecting "Inspect". Alternatively, press Command+Option+C (Mac) or Control+Shift+C (Windows, Linux, Chrome OS).
The developer tools will open on the right or bottom of your screen. Select the “Elements” tab.
Press Control+F to open the search bar and paste the image URL. Then, delete the root domain from this URL (for example, if your image URL is "yourdomain.com/page/image.jpg", paste only "/page/image.jpg" in the search bar).
All the way to the right of the search bar, you will find the count of found matches. Use the arrow next to it to find where all of the images are placed within the code.
To show where in your page each of your images are located, right-click at the end of the line of code you want to reveal and select "Scroll into View".
Images with an alt attribute appear in your website's code along with the tag alt="" and a descriptive text between the quotation marks:
