Why Aren’t All My XML Sitemap Images Indexed in Webmaster Tools?

[CommercePundit]

Hi,

Here is our main sitemap

http://www.vistastores.com/newsitemap/main_sitemap.xml

We have submitted all category wise sitemap having Image Tags :

For eg -  Ac Category

http://www.vistastores.com/newsitemap/window_ac_sitemap.xml

contains iamge tag -

image:imageimage:locimage:captionimage:title</image:title></image:caption></image:loc></image:image>

All our 142 category pages includes these format.

Still the sitemap report on 4-Apr-2013 says:

Sitemaps content

Web pages:
Submitted    14,569
Indexed        11,219

Images:
Submitted    21,442    
Indexed        11,762

You can see major difference in submitted v/s indexed.

I have looked into Jay Simpson  question - http://www.seomoz.org/q/any-idea-why-our-sitemap-images-aren-t-indexed to find this answer but didn't get Perfect & clear answer.

I need urgent answer to fix this issue.....

Thanks David Yeager!

You have answered very well to solve my question.

There are several reasons that this happens.  The main being that Google simply does not index everything you have, especially if many of them are the same size, same meta, or they find patterns real similar to other sites.  The more social signals you have, the longer people stay on pages etc. will have an effect on what they index.

But the easy answer is that they are not all indexed because Google does not want to.  

In their words:

The number of indexed URLs is almost always significantly smaller than the number of crawled URLs, because it does not include URLs that have been identified as duplicates or non-canonical, or less useful, or that contain a meta noindex tag.
