When it comes to making your website more accessible and improving your search engine visibility, alt text often flies under the radar. Whether it’s a simple description of an image or a detailed note about a complex graphic, alt text helps ensure that everyone—not just search engines—can understand the visuals on your site. That’s why knowing how to see alt text on website pages is so valuable.
In this guide, we’ll explore exactly how you can view and assess the alt text on your pages, as well as best practices for keeping it effective and meaningful.
Understanding Alt Text and Why It Matters for Websites
Alt text plays a critical role in how websites communicate information to both users and search engines. While primarily designed to improve accessibility, it also impacts search engine rankings and overall site performance.
Ensuring that images include meaningful descriptions allows websites to be more inclusive while improving search visibility.
The following sections will explore what alt text is, why it holds significance, and how it directly influences SEO.
What is Alt Text and Why is it so Important?
Alt text, or alternative text, is an HTML attribute assigned to images that provides a written description of their content. This text serves as a substitute when images fail to load and is read aloud by screen readers for visually impaired users.
Well-written alt text makes websites more accessible while also giving search engines context about the images on a page.
For accessibility, alt text ensures that all users, regardless of ability, can understand the visual elements of a website. Without it, screen readers have no way of conveying image content, leading to a frustrating user experience.
From a technical standpoint, alt text also enhances site usability by displaying descriptions when images are missing due to slow connections or browser issues.
How Alt Text Impacts SEO and Search Engine Rankings
Search engines rely on text-based data to understand and index web content. Because they cannot process images the way humans do, alt text helps provide critical context.
When search algorithms crawl a website, they assess alt text to determine an image’s relevance to the surrounding content. Well-optimized alt text can improve rankings, especially in image search results.
Additionally, alt text contributes to keyword optimization without overloading a page with unnecessary repetition. When written naturally, it strengthens a page’s topical relevance, helping search engines connect content with user intent.
It also plays a role in Google Image Search, where well-described images are more likely to appear in results.
Beyond rankings, missing or poor alt text can create usability issues, affecting both search performance and user engagement. By implementing effective, descriptive alt text, websites can improve accessibility, increase search visibility, and create a better experience for all visitors.
How to See Alt Text on a Website: The Best Methods
Ensuring that images on your website have appropriate alternative text (alt text) is essential for accessibility and SEO. Understanding how to view and assess alt text can help maintain these standards.
Using Browser Developer Tools to Inspect Alt Text
Google Chrome:
- Access Developer Tools: Right-click on the webpage and select “Inspect,” or press Ctrl+Shift+I (Cmd+Option+I on Mac) to open the Developer Tools panel.
- Locate the Image: In the “Elements” tab, hover over the HTML code to highlight corresponding elements on the page, helping you find the desired image.
- Check the Alt Attribute: Once the image’s <img> tag is located, examine the alt attribute within the tag to view its description.
Mozilla Firefox:
- Open Developer Tools: Right-click on the webpage and choose “Inspect Element,” or press Ctrl+Shift+I (Cmd+Option+I on Mac).
- Find the Image Element: Navigate through the “Inspector” tab to locate the image’s HTML code.
- View the Alt Text: Inspect the alt attribute within the <img> tag to see the alt text provided.
How Alt Text Checkers Simplify the Process
Manually checking alt text across an entire website can be time-consuming, especially for sites with many images.
Alt text checkers simplify this process by automatically scanning web pages and identifying images with missing, empty, or poorly written alt text. These tools help ensure accessibility compliance and improve SEO by making sure all images are properly labeled.
Many alt text checkers provide detailed reports, showing which images lack alt attributes and offering suggestions for improvement. Some tools also integrate with broader SEO auditing platforms, allowing users to optimize their entire website in one place.

The Best Practices for Writing Effective Alt Text (Quick Guide)
Alt text should be clear, concise, and meaningful to improve accessibility and help search engines understand images.
These best practices ensure that every image has effective alt text:
- Describe the Image Clearly – Use specific language that accurately conveys what the image shows.
- Keep It Concise – Avoid unnecessary details or overly long descriptions.
- Avoid Keyword Stuffing – Use relevant keywords naturally without forcing them.
- Do Not State ‘Image of’ or ‘Picture of’ – Screen readers already identify elements as images, so this is redundant.
- Consider the Image’s Context – Alt text should align with the surrounding content. If the image serves a functional purpose, describe what it conveys rather than just its appearance.
Using these best practices ensures that alt text is helpful, readable, and optimized without unnecessary clutter. For a full guide on how to fix missing image alt text, you can refer to our in-depth guide here.
