The Importance of HTML Image Tags

Images are an essential part of any website. They help to tell a story, display products, and services and highlight specific areas of your site. The list goes on and on. One of the most important things about images is that they need to be optimized for search engine optimization (SEO) and readability by humans and machines. HTML image tags are what allow you to do this. In today’s post, we’ll go over some basic principles when writing image tags in HTML so that you can start optimizing your images for SEO!

What is an HTML image tags?

To understand an HTML tag, it’s vital to know how a web page works. A web page consists of content such as text and images, which can be styled using CSS.

One of the most common ways to use HTML tags is when defining images. Using appropriate tags in your code, you can add relevant information about each image, such as the image’s title and alt text (what appears when someone hovers over an image without seeing its full caption).

The alt tag is significant because it can help make your site more accessible. If someone turns on a setting that makes images invisible, the alt text will appear where you’d typically see them. Using HTML image tags is also crucial for SEO. The search engine bots need to know what each image is about to rank it accordingly.

Why are HTML image tags important?

Image tags help search engines understand the content of a web page, how it’s laid out, and how to rank it. 

For example, an image with text inside it will be treated as text by search engines. So, including an ALT attribute provides context for people who can’t see your images.

Search engines can also tell where each image is located on your page, allowing them to understand your layout better. For example, if two images are side by side but there’s no space between them, it might look like there’s just one giant image instead of two separate ones. This would affect how well search engines rank that particular web page because they’d think, “oh well, this website doesn’t have any good layout at all!”. So if we have another image next to this one, our website has been given some structure since both images aren’t squished together anymore!

People who are blind, deaf, or have trouble reading can benefit significantly from using ALT attributes on your HTML images. Including alternative descriptions will help them understand what each picture is showing without relying heavily on verbal descriptions alone.

When to use Alt Tags?

The Alt attribute is most useful when an image is essential to the content of a page. It’s also useful on pages where images are unnecessary, but you want to help visitors with visual impairments access the same content that others can see. This can be especially true in sites with lots of graphics and content.

To determine whether an image should have an alt tag, ask yourself this question: “Is this more than just decoration?”. If yes, then you need to add an alt tag for it!

If your answer was no (if it’s just decoration), then you don’t need an alt tag. This is in cases where nothing specific about that image needs explaining for someone who might visit the site later or use screen-reading software like JAWS or NVDA. 

So if something isn’t intending to get clicks from search engines or other users who aren’t visually impaired yet don’t have any struggles when visiting websites–then leave those folks out of this equation altogether by skipping out on adding anything related directly under those tags. Otherwise, they’ll end up overwhelmed by too much information, which could lead them astray rather than helping them understand.

How to add HTML image tags?

To add an HTML image tag, you use the HTML element. To define your image, you need to provide the alt, title, and src attributes.

The alt attribute defines what will appear in a browser if the image fails to load. This is important because many blind people rely on screen readers that read out text embedded in images. The alt attribute should be unique and descriptive so that it’s clear which part of the page it represents. 

The title attribute gives more detailed information about an image, like when it was created or who uploaded it. Imagine someone browsing through your website without seeing anything. A screen reader could read out “New York City Skyline at Night” and tell them that John Smith took this picture with his smartphone camera.

The source attribute defines where images are located on your server so that browsers know where they can find them. If you don’t specify this value, browsers will try their best but often fail miserably because they cannot locate any data source for those files.
