One of the most popular forms of blogging income has been by running Google Adsense ad units. Once the Adsense code has been inserted into a blogs pages, Google reads the sites contents and delivers ads relevant to the content it finds. If your pages are dominated by graphics then Google may not be able to determine the contents and thus provide relevant ads.
The Adsense Blog – Inside Adsense - has some good tips for optimizing your images so that Google can provide relevant ads. The most important tip for bloggers to think about is to try and imagine your site with the graphics missing.
You don’t have to imagine it. Turn the images feature off in your browser, and then visit your pages. If you use Firefox then go to Tools/Options/Content and uncheck Automatically Load Images. Now you can see your site as Google sees it when it is trying to provide relevant content.
If you page is fairly blank, you have a problem. Simple tasks such as using ALT tags in the image information will help. Consider adding a small amount of text using keywords close to the image describing the general theme of the image(s).
Once you have a reasonable amount of text that is keyword optimized, Google can proceed to provide ads that are relevant to your content. This may improve your overall click rate and increase your blogging income potential.
