Alt tags, also known as alternative text, are HTML attributes that provide a description of an image for search engines and visually impaired users. Alt tags play an essential role in SEO, digital marketing, content marketing, ad tech, and advertising. In this post, we will answer the six most popular questions about alt tags and their importance in SEO.
An alt tag is a piece of HTML code that describes an image on a webpage. It helps search engines understand what the image is about and provides visually impaired users with a text description of the image. Alt tags are also used when an image cannot be displayed on a webpage due to slow internet speed or technical issues.
Alt tags are important for SEO because they help search engines understand the content of a webpage. Search engines cannot see images, so alt tags provide them with context and relevancy. Properly optimized alt tags can improve the ranking of a webpage on search engine results pages (SERPs).
To write effective alt tags, you should keep them concise and descriptive. Use relevant keywords that describe the image accurately. Avoid using generic words such as "image" or "photo." Use hyphens to separate words instead of underscores or spaces.
If you do not use alt tags, search engines will have difficulty understanding what your images are about. This can negatively impact your website's ranking on SERPs. Additionally, visually impaired users will not be able to access the information conveyed by images, which can harm your website's accessibility.
You can use various SEO tools such as SEMrush or Ahrefs to check if your website has optimized alt tags. You can also check the HTML code of a webpage and look for the "alt" attribute in the "img" tag.
In conclusion, alt tags play a crucial role in SEO and website accessibility. By writing effective alt tags and optimizing them properly, you can improve your website's ranking on SERPs and ensure that all users have access to your content.
