Remove and Insert Metadata Keywords into Jpeg Images for Search Engine

Will the metadata keywords in gif, jpeg and jpg, png images influence how search engine index our images? Apparently, the question of the relevance of the metadata embedded within the image for search engine relevance and ranking is a hotly debated topic within the SEO experts.
Last week, I’ve decided to carry out my own research, I embedded a ’secret’ keyword into all the metadata section of an image and uploaded it to my blog and his the publish button. Please note that prior to the test, I carried out a search for that ’secret’ keyword and the results returned by Google is zero. Weeks went by and the result for that particular keyword is still zero, I google for the post and discovered that Google crawled the post last week.
Conclusion? Metadata does not influence or determine the ranking of your image.
Insert Metadata Keywords Into Image
Most image editing software can perform the basic task of inserting exif metadata keywords into jpeg, png, gif and more. Photoshop is one of them.
To insert metadata into images in photoshop, go to ‘file’ then ‘file info’. A dialog box will appear and key in the relevant metadata keywords.
Remove Metadata Keywords
Since metadata keywords do not influence your image ranking in search engine, the next logical step is to remove them. This enables you to reduce around 10 – 30kb off from your image, depending on a number of factors. Multiple these with the thousands of images in your server, you could possibly save lots of bandwidth and money by removing them, not to mention the smaller file size allows your blog to load faster.
Try Stripper, its a batch metadata remover for jpg and png. Just drag and drop the file or folder into the dialog box and everything is automatic. Download Stripper, freeware.

January 19th, 2009While saving bandwidth might be a viable reason for removing metadata from some images, it makes no sense for those with any commercial value.
Keep in mind that there are several countries considering various types of “orphan works” legislation, which would reduce or eliminate penalties for the use of images where an author can not be located.
If you remove metadata from an image, especially creator or contact information, this will make it easy for others to claim these images as “orphaned” images, and avoid paying you any licensing fees. In addition, it could very well limit or remove any opportunity to pursue them for copyright infringement.
Including even minimal copyright and contact information should only take 2 to 3 kilobytes in an image. I’m not sure where you get your figures of 10-30 kb, unless you are dealing with an image that includes a “fully loaded” metadata container.
I would suggest taking a look at the Metadata Manifesto for another viewpoint on this issue.

Hope that provides another perspective.
