Every image you add must be optimized both for search engine spider and users. Search Engine spiders can only read text but not images. So you need to use some special tags for your images in order to give them some meaning. To do that you have to apply the following:
- Alt Text: ALT text or Alternate Text is the text to describe your image when your mouse moves over an image on your web page. The text should be meaningful but short. You can use your relevant keywords as ALT text. If your browser is not able to load the image for some reason, the alt text is used in place of that particular image.
- File Name: Always use meaningful file name for your images, use names like “seo-techniques.jpg” instead of meaningless “ATC3604.jpg”. Keep image file name same or similar to the ALT text.
- Image Size: Check the image size, if it is too heavy it would take time to load the page and could affect your website performance. So, reduce the file size without ruining the image quality (at least not much).
- Image Title: always use the title tag in images which will show the title as tool tip when a user moves his mouse over the image. Example of an image with title tag: [img src=”http://imagelocation.jpg” alt=”Image description” title=”Title of the Image”]
- Image Linking: Whenever you want to link to your image, use the image keywords in your link text. Example: use “Learn SEO Techniques”, instead of “Click here to view” as the anchor text.
