Image originality - The panelists agree that there is a special advantage to taking original photos, even if you are a retailer who already receives photos elsewhere such as from a manufacturer. "The more control you have over the images on your site the better." says Evans. "You can brand them with your logo, url or trademark. It also allows you as the retailer to present the product in the best possible way that will convert with your own audience, not to mention allowing you to present the features in a different way than other competitors.
Image Naming - "Make the image names of your files match what is actually represented in the file," says Thurow. "The image name will appear beneath the graphic image in search results. It helps to communicate to searchers that they are viewing the desired graphic image. "Do NOT expect your photo editing program's default settings to give you optimized file names," she continued. "Default names communicate nothing to the search engines on their own. Make sure to set up your own file naming structure in advance."
Tagging - More content is "King" It's a given to make sure that your images match the actual products and keywords you place in there, along with ample descriptions of what you're featuring. But you should also take full advantage of the many special contextual tags for social sites with image search. Not only are image names given more weight than regular search results, but you can also add special tags such as captions, comments, cross-grouping, location, and themes.
Image Quality - Start off with good quality pictures, and make necessary resolution adjustments between your full size images and your thumbnails. Smith mentions that pictures with good contrast tend to work better. "When they're reduced down to the thumbnail size, stronger contrast is needed to better discern image, which will lead to more people clicking and linking to image." he says.
Image Formatting - Thurow advises saving photos as JPG files, and other graphic image types as GIFs "Search engines are going to interpret a GIF as a standard graphic image with 256 colors," Thurow said, "and JPGs as photos (because photos have millions of colors." says said Shari Thurow, Webmaster and Marketing Director at Grantastic Designs, Inc..
Expand Audience Base - Be broad in your subject matter. Image search is not just for retailers directly reaching customers. "There are all sorts of innovative ways you can get people interested in your company and hence build up traffic and conversions. For example, factories might show steps in product manufactures, hotels might show furniture & decorative art in addition to details on their rooms, and restaurants might show picturesque views or special event rooms."
Optimize the page with the image - Optimize the page the image appears on can be just as important as optimizing the image itself. "Optimizing the actual page for contextual search improves graphic images search," Thurow added. "Search engines also look at text surrounding a graphic image to determine relevancy." says Thurow. "Text within the anchor tag and next to anchor text is especially going to influence image-search rankings," said Thurow. "If you can reasonably put labels and captions on key graphic images, try and do so."
