It’s probably fair to say that most of us know about image searching on SEs like Google, Yahoo, Bing and Ask but we keep noticing that many people totally ignore the potential of this search type to market their websites. Not to put too fine a point on it but you can often achieve very good results by using image search optimisation – you just have to think a little about your offerings and the related image keywords you would expect people to search for. For example if you are a travel agent then you may want to optimise your images for the keywords “Air Travel” or “Aeroplane” – or if they are destination based then name them after the destination name.
For a list of image keywords which are popular you could try looking at sites like iStockPhoto or Flickr
In order to optimise your images for image search make sure you pay close attention to the use of the actual image file name and the image “title” attribute as well as the standard “alt” attribute. Try to keep names and attributes under 5 words. And if possible make them relevant to your overall page for further on-page SEO.
Once you’ve got your image SEO in place you can use Google Analytics to track visitors coming from image searches – although to track the keywords used you would need to slightly modify your GA JavaScript code to add images.google.co.uk and others as the referring search engine – see here if you need more details on achieving this: http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=57046
