I really enjoyed the recent post by Amy Balliett 3 Tips to Plan Your SEO Campaign for The Visual Web, which made me think that maybe you would like to know how to optimize your images within WordPress.
To begin, save your image with a name, not a ridiculous string of numbers. Example: SushiPlatterTurksSeafood vs DSC_0006_4742.jpg. Always remember, Google can read, but not see (well to the beset of my knowledge those spyders can’t see yet, but I know those Google Glasses are freaking you out!)
Then within WordPress, complete all of your search engine fields:
Title – Tell what the photo is about and if applicable add a geographic location.
Alt Text – This is very important, Google sees this + the visually impaired will get this text read to them.
Caption – I don’t think you get seo credit or penalties for captions, I actually don’t like captions, but do what works for you.
Description – Complete this for your own organization, it won’t help your seo.
Other Image SEO Tips:
Make sure the on page content relates to the image.
Mix up your image keywords – you don’t want to continuously use the same words.
With Google alone getting billions of searches each month it is important to pull out all the stops to get ranked for your target keywords. You many have trouble competing in the regular organic listings, but you could potentially rank well in image searches if you take an extra moment to optimize your photos.
