Big Oak SEO Blog

Any good SEO campaign will put the emphasis on ranking your site for the content of the site. But overlooking the images on the site can be a big mistake especially if your site is selling products which naturally use imagery as part of the sales pitch. So why not use those image to draw visitors through organic image search?

Your first step should be to set up a Google Account where you can use Webmaster Tools. Inside the Webmaster tools you will find an option under Tools named “Enable enhanced image search”. When this option is enabled Google will start cataloging your images for placement in the search engine results for images which can increase your traffic, especially if you can show in the search results that show images above the organic search results. (See example of Google search with images above organic results for the search term ‘oak tree’)

After you have instructed Google to look for your images, you want to be sure your images are telling Google and the other search engines exactly what they are about. How do you do this? Here are some things to pay attention to and think about when using images. I’ve listed them in order of “my importance”.

1. Image Size Does Matter - Larger images tend to rank better. Most image results that show in the top three I have done test searches on have been over 280 pixels in both directions. Bigger images make sense to show first, all other things being equal. I would shoot for 300 x 300 to be safe.
2. Image Close to Relevant Text - Keyword above or below the image in the same DIV -or- keyword in the same paragraph as the image, close to the image. Keyword should be in the same <td> (table cell) as the image.
3. Page Title & Page Theme - The title, content and image should all be connected.
4. File Name - It can be difficult to add the name of the image to the file name, especially if the shopping cart software doesn’t allow it, but when you can, be descriptive.
5. Alt Tags - Alt tags are designed to provide alternative text when the images cannot be displayed. They should be descriptive of the image. Example: <img src=”oak-tree.jpg” width=”200″ height=”350″ alt=”Oak Tree”>
6. Image Title Tags - This text shows up when you rollover the image in a popup. They should also describe image. Example: <img src=”oak-tree.jpg” width=”200″ height=”350″ alt=”Oak Tree” title=”Oak Tree”>
7. Image Sitemap - Okay, this is an idea which may or may not be of any help, but it certainly can’t hurt and if you feel your images are important enough to help your rankings then creating a sitemap with descriptive links to your important images might be the extra boost to get your images to the top of the search engine results.

Alt/Title for images have been spammed too much (like Meta tags) so I don’t think they play much of a factor at all anymore in images search.Please share any successes you may have had with image search or ideas you have tried. I’m especially interested in anyone who has tried an image sitemap or what you think of this idea.
