When it comes to SEO, every detail counts. And if you're not optimizing your images properly, then you are missing out on a huge opportunity to improve your search engine rankings. One of the most important and often overlooked aspects of image optimization is the "Alt Attribute." In this post, we'll discuss what it is, why it's important, and how you can use it to improve your website's SEO.
The "Alt Attribute" (short for alternative attribute) is an HTML attribute that provides alternative text for an image if it cannot be displayed. It is used by screen readers and other assistive technologies to describe images to visually impaired users. It also helps search engines understand what the image is about.
Search engines cannot "see" images like humans can. They rely on alt attributes to understand what the image is about and its relevance to the content on the page. By using descriptive alt text, you help search engines index your images properly and improve your chances of ranking higher in image search results.
Writing effective alt attributes involves describing the image accurately and succinctly. Use keywords in your alt text, but don't stuff them in unnaturally. Also, avoid using generic phrases like "image" or "picture." Instead, be specific and descriptive about what's in the picture.
There's no set rule for how many characters your alt text should be but try to keep it under 125 characters. This will ensure that it doesn't get cut off or truncated in search results.
No, you should never use alt attributes for SEO manipulation by stuffing them with irrelevant or spammy keywords. Doing so could result in penalties from search engines and damage your website's reputation.
Ad tech platforms use alt attributes to identify ad inventory on a webpage. It helps them understand what type of ads would be relevant to that page and its content. By using accurate alt attributes, publishers can increase their chances of serving relevant ads that generate more revenue.
In conclusion, optimizing your website's images with descriptive alt attributes is essential for improving its SEO performance. By following these tips and best practices, you can ensure that your website's images are properly indexed by search engines and help visually impaired users understand their context.
