The Awesome Alt Attribute: What is it? How to use it? Secret SEO booster?

Introduction: The Importance of Image Alt Tags

Alt tags are an important part of SEO. They provide information about the image to search engine crawlers, which helps them understand what the page is about. The alt text should be between 50 and 250 characters in length and contain keywords that are relevant to the page’s content. It is also important to include keywords in the alt text so that they can be found by search engines, as they will not be able to read images or videos.

What is it?

The alt attribute is a Hypertext Markup Language(HTML) attribute that provides alternative information for images. If a web image does not load properly, overall user experience suffers. When a user has low bandwidth as a result, web browsers place alt text as the alternative to the intended image.

How to use it?

The alt tag is inserted into the image tag. It’s best used when an image contributes meaning to the current page.

alt=”[insert text here]”


The alt tag is used to describe the image.

Tips to avoid errors:

  • ALWAYS surround alt text with either single or double quotations.
  • DO NOT insert a space before or after the equal sign.

4 Reasons Why Image Alt Tags are Important for SEO

Image alt tags are one of the most important things to have on your web pages. They are an SEO technique that can help you rank higher in search engines.

1. Image alt tags can be used to provide more information about the image.

2. They also provide a context for what is going on in the picture, which can help people find your website when they search for keywords related to the image.

3. Image alt tags tell search engines what an image is about and can also be used as keywords by themselves or as part of a larger keyword strategy.

4. When you use alt tags, it makes your images more likely to show up in image searches, which means that people will be able to find your website without typing in any words at all!

Is It Relevant For SEO?

A picture tells 1,000 words, but the search engines don’t have eyeballs.

The alt attribute is seen as insignificant and is commonly overlooked. For this reason, if you were to properly utilize the alt attribute, your content will have that edge over the majority that leaves it out. More importantly website visitors with vision impairments cannot see the website’s images. Adding the alt tag and descriptive text around the image helps add context to these hidden images.

If an image is crisp and clear, to humans, the photo is of high quality. For search engines to understand images they use the alt attribute. If an alt attribute is highly descriptive while being concise, search engines will love you! They would be able to recognize the image topic and relevance.

Images do not always load, therefore the addition of alternative text is a must for a better user experience. Content must be understood by both users and web crawlers.

Tip: To further maximize your SEO, be sure to incorporate your target keywords in the alt text as well.

Search engine optimization is your professionalism to search engines. The more professional you appear, the more likely they will recommend what you have to offer. In terms of Image SEO, think of the alt attribute as beams to a skyscraper. Without it there is no support.

3 Tips For Choosing An Imagery That Is Acceptable and Describes the Subject

It is not enough to just have a well-written and informative text. You need to use images that are descriptive and will help the reader understand your content better.

Here are three tips for choosing imagery that is acceptable and describes the subject.

Tip 1: Make sure that the image is relevant to your content. If you are writing about gardening, don’t use an image of a lion on your website.

Tip 2: Make sure that the image has a high-quality resolution. This will help it load faster and look better on your website or social media page.

Tip 3: Make sure that you are not using copyrighted images without permission from the owner or creator of the photo or artwork.

Best practices for writing effective and descriptive alt-text for images

Images are often the only way to convey an idea or message. They can also be used to add a visual dimension to a website, blog post, or social media post. The alt-text is the text that appears when someone hovers their mouse over an image. It is important that this text is descriptive and relevant so that it will help people understand the image better and in turn click on it more often.

Some best practices for writing alt-text for images that will help them stand out:

  • Use descriptive words that accurately describe what the image shows.
  • Include keywords in the description.
  • Keep the description short but informative.
  • Use consistency in your descriptions so they are easy to find.

Concluding Thoughts on the Importance of Image Alt Tags

The alt tag is an HTML attribute that provides alternative text for the image. It is used in case the browser cannot show the image. The alt tag should not be a duplicate of the title of the page or article, but it should give a description of what is in the image. It should also be keyword rich and provide as much information as possible about what is in the image so that search engines can index it properly.
