Just like text, images can be a great source of organic web traffic for your small business.
Google delivers as many search results for images as it does text. So how do you optimise your images for SEO? That’s where alt text comes in.
Alt text is a one-sentence description of the image and is employed within HTML code. Adding alt text to images makes them more accessible; for example, people with visual disabilities using screen readers are able to better understand on-page site images. Also, if an image fails to load, alt text will be displayed for the user to understand what the image is about.
How to use alt text
Every image that your small business uploads to its website should have alt text. Below are a few important notes on how to use alt text.
It should have a maximum of 100 characters; any longer and some words may be cut off by the screen reader because the length of alt text visible to the reader is determined by the size of the image.
Employ keywords in the alt text. Keywords help Google spiders to better crawl and rank your site. However, they must be used sparingly. Alt text should make sense to the reader but if you stuff it with keywords without any regard to its descriptive purpose, it will lose its meaning. And neither Google nor users will be able to make sense of it.
Alt text must be specific and descriptive. The point is to provide an explanation so that a user will understand exactly what the image shows even when they do not see it.
It is also important to make a connection between your small business website’s alt text and the contents of the article. It will improve accessibility through organic search engine results.
