In today’s digital age, a robust online presence is crucial for healthcare practitioners. One essential aspect of enhancing your website’s visibility and accessibility is using image alt tags for SEO.
This article will delve into image alt tags, their importance for SEO, particularly for healthcare websites, and how they contribute to accessibility.
Additionally, we will present the common mistakes that website owners should avoid and provide a comprehensive guide on how to write effective image alt tags for SEO.
What Are Image Alt Tags?
Understanding the basics of image alt tags is essential for any healthcare website looking to improve its SEO and accessibility.
Let’s explore what image alt tags are and how they function within your site’s HTML code.
The Role Of Alt Tags In HTML Code
Image alt tags, also called alt text or alternative text, are descriptions added to the HTML code of an image.
These tags serve as textual alternatives to images, providing context to search engines and users who cannot view the images.
The alt attribute is added within the image tag in the HTML code of the chosen web page. It looks like this:
<img src=”image.jpg” alt=”descriptive alt text”>
This alt attribute is crucial for search engine optimisation (SEO) and web accessibility.
History And Evolution Of Alt Tags
Alt tags have been a fundamental part of HTML since its inception. Originally, they were designed to provide text descriptions for images to aid users who had slow internet connections and disabled image loading to speed up page loading times.
Over time, their role has evolved significantly, especially with the rise of search engines and the emphasis on accessibility.
The Distinction Between Alt Text And Image Titles
It’s important to distinguish between alt text and image titles. While both can be included in the HTML image tag, they serve different purposes.
The alt text describes the image, which is crucial for SEO and accessibility. In contrast, the image title is often used as a tooltip that appears when a user hovers over the image. Properly using both can enhance the user experience and SEO.
Why Are Alt Texts Important For SEO?
Image alt tags are not only a technical requirement but vital to enhancing your website’s SEO. Let’s explore how alt tags can improve your site’s visibility and user experience.
Enhancing Search Engine Visibility
Image alt tags are significant in improving your website’s visibility on search engines like Google. Search engine crawlers use alt text to understand images’ content, which helps index them appropriately. This process enhances your website’s chances of appearing in image search results and the main search engine results pages (SERPs).
Boosting Image SEO
Images with descriptive alt text are more likely to attain higher rankings in Google Images and other search engines. This can drive more traffic to your practice’s website, as users often search for images related to specific medical conditions, treatments, or procedures.
Improving User Experience
Alt text provides an auditory description of images for visually impaired patients relying on screen readers. This makes your website more accessible and ensures a positive user experience for all visitors.
Supporting Broader SEO Strategies
Alt text contributes to broader SEO strategies by reinforcing the content and context of your web pages. When search engines can accurately interpret your images, they gain a better understanding of your site’s overall content, potentially improving your rankings.
Enhancing Click-Through Rates
Images that appear in search results with compelling and relevant alt text can increase click-through rates. Patients are more likely to click on images with clear and descriptive text, driving more traffic to your site.
Facilitating Better Content Organisation
Using alt text helps organise your content more effectively. It allows you to label and categorise images properly, enabling search engines to crawl and index your website.
The Importance Of Image Alt Tags For Healthcare Websites
Healthcare websites have unique needs when it comes to SEO and accessibility. Understanding the benefits of image alt tags for healthcare sites can help practitioners enhance their online presence.
Building Trust And Credibility
Healthcare websites must build trust with their audience. Using image alt tags for SEO can help convey professionalism and attention to detail, increasing your credibility.
Increasing Website Traffic
Effective use of alt text can lead to higher search engine rankings, attracting more visitors to your site. This increased traffic can translate to more patients seeking your services.
Ensuring Compliance With Accessibility Standards
Healthcare providers should comply with accessibility standards to ensure their websites are usable by everyone, including those with visual impairments. Adding descriptive alt text to images is key to meeting these standards.
Enhancing Patient Education
Alt text can be used to enhance patient education by providing detailed descriptions of medical images, infographics, and diagrams. This makes complex medical information more accessible and understandable to a broader audience.
Demonstrating Commitment To Inclusivity
Using alt text demonstrates a commitment to inclusivity and accessibility. This can positively impact your brand’s reputation and help build stronger relationships with patients and the community.
How Alt Text Improves Website Accessibility
Improving accessibility is a critical aspect of modern web design. Alt text plays a significant role in making websites accessible to all users, including those with visual impairments.
Providing Descriptions For Screen Readers
Screen readers depend on alt text to describe images to visually impaired users. Descriptive alt text ensures these patients can understand the content and the exact context of the images on your practice’s site.
Enhancing Navigation
Alt text can improve navigation for users with disabilities, allowing them to move through your website more easily and understand its structure and content.
Supporting Web Accessibility Initiatives
Adding alt text contributes to broader web accessibility initiatives, promoting inclusivity and equal access to information.
Improving Overall User Experience
Accessible websites provide a better user experience for visitors, not just those with disabilities. By incorporating alt text, you create a more inclusive and user-friendly environment.
Reducing Bounce Rates
Websites that are accessible and simple to navigate tend to have lower bounce rates. Users who can easily access and understand your site’s content are more likely to stay and explore it.
Common Mistakes To Avoid When You Write Image Alt Text
Even with the best intentions, making mistakes when writing an image alt tag is easy. Awareness of these common pitfalls can help you create more effective, SEO-friendly alt tags.
Keyword Stuffing
While including relevant keywords in your alt tags is important, avoid keyword stuffing. Overloading your alt attributes with keywords can lead to an unpleasant user experience and may be penalised by search engines.
Generic Descriptions
Avoid using generic descriptions like “image” or “photo.” Instead, provide specific, descriptive alt text that accurately represents the image content.
Unnecessary Decorative Images
For purely decorative images that do not provide important information, use an empty alt attribute (alt=””). This informs screen readers to skip the image, avoiding unnecessary distractions.
Failure To Describe The Image’s Purpose
Ensure your alt text describes the image and its purpose in the context of the content. This provides more value to users and search engines.
Lack Of Context
Alt texts should reflect the contexts in which images are used. Descriptions should align with the surrounding content to provide a cohesive user experience.
Long Phrases
The alt text should be concise yet descriptive. Avoid long, complex phrases that might be difficult for screen readers to interpret quickly.
Outdated Alt Text
As your website evolves, ensure you update alt text to reflect changes in content and context. Outdated alt text can confuse users and mislead search engines.
Things To Consider For Optimal Alt Texts
Writing effective image alt tags requires a strategic approach. Follow these best practices to create alt text that enhances your SEO and accessibility efforts.
Be Descriptive Yet Specific
Your alt text should provide a clear and concise description of the image. Include relevant details that help users and search engines understand the image’s content and context.
Use Relevant Keywords
Incorporate relevant keywords naturally into your alt text. This helps search engines associate the image with specific search queries, improving your site’s SEO.
Use Simple Language
Avoid complex or technical language in your alt text. Use simple, clear language that is easy for all users to understand.
Check For Errors
Before finalising your alt text, review it for spelling and grammatical errors. Mistakes can detract from the professionalism and effectiveness of your alt tags.
6 Simple Steps To Writing Image Alt Tags
Creating effective alt text involves several steps. These six steps ensure your image alt tags are SEO-friendly and accessible.
Step 1: Analyse The Image
Look at the image and determine its subject, context, and purpose. Consider what information it conveys and how it relates to the surrounding content.
Step 2: Identify Relevant Keywords
Select keywords that are relevant to the image and its context. Ensure they align with your overall SEO strategy and target audience.
Step 3: Write A Concise Description
Craft a concise description that accurately represents the image. Include relevant details and keywords naturally within the text.
Step 4: Review For Clarity And Accessibility
Check your alt text for clarity and accuracy. Make sure it provides a clear description that enhances SEO. Also, write alt text with accessibility in mind. Consider how visually impaired users will interpret the description and aim to provide clear and helpful information.
Step 5: Test With Screen Readers
Test your alt text with a screen reader to ensure it provides a useful and accurate description for visually impaired users.
Step 6: Update Regularly
Review and update your alt text regularly to reflect changes in content and context. Keeping your alt tags current ensures they continue to provide value.

Monitor Performance
Track the performance of your images and alt text using analytics tools. Monitor which images are driving traffic and adjust your alt text strategy accordingly.

Frequently Asked Questions
What is the difference between an image alt text and an image caption?
Image alt text (alternative text) is a description embedded in an image’s HTML code. It is primarily used for accessibility purposes and helps search engines understand the image’s content. Screen readers read alt text for visually impaired users and appear in place of the image if it fails to load.
On the other hand, image captions are visible text displayed alongside or below an image on a webpage. Captions provide additional context or information to users but are not part of the HTML code like alt text. While including captions can enhance the user experience, it does not directly impact SEO or accessibility in the same way as writing alt-text descriptions.
How long should my image alt text be?
The image alt text should be concise yet descriptive, typically 100 to 125 characters. The goal is to provide enough detail to convey the image’s content and context without overwhelming the user or search engines. Focus on creating clear and informative descriptions relevant to the image and its purpose on the page.
Can I use the same alt text for multiple images?
Using the same alt text for multiple images is generally not advisable, as each image should have a unique description that reflects its specific content and context. Reusing alt text can lead to a lack of clarity and hinder accessibility for users who rely on screen readers. Instead, craft distinct alt text for each image to provide accurate and meaningful descriptions.
Maximising The Impact Of Image Alt Tags For SEO On Healthcare Websites
Image alt tags are a powerful tool for enhancing the SEO and accessibility of healthcare websites. By understanding their importance and following best practices, healthcare providers can improve their online presence, attract more visitors, and ensure their websites are accessible to all users.

Avoid common mistakes, use advanced strategies, and leverage tools and resources to optimise your alt text for maximum impact.
