When you’re optimizing your site for Google and other search engines, images may not be everything, but you shouldn’t overlook them. According to Google, you can use Google Image Labeler and other tools “to associate the images included in your site with labels that will improve indexing and search quality of those images.”
To opt in to enhanced image search:
Image search is less competitive than keyword search if, for no other reason, fewer sites bother to make sure their images comply with HTML standards. There’s a very good chance you’ll see a jump in traffic, or at least I did.
To be compliant, your images should include:
- Alt attribute that describes what the image is
- Title attribute that appears when you mouse over the image
- Height and width of the image
- URL where the image resides
Use Google Analytics to find out what percent of your traffic comes from image search and keep an eye on that figure over several weeks. You might be surprised by the results.
