Hi
Some weeks ago we bought your component (pro version) and we recreated the sitemaps in all languages.
There are 849 pages send and only 35 indexed.
We have waited for weeks checking google webmaster tools, we dont see any reason for this. We used a js banner at the homepage which we have removed in case that afected.
Our sitemap is located here
http://comenaranjas.com/es/mapa-del-sitio.html we have one per language and the URL send is the one that your component says:
http://comenaranjas.com/index.php?option=com_jmap&view=sitemap&format=xml&lang=es
We even added the line at robots and submited from the button of the URL.
If you could please check if there is something obvious causing an issue.
Regards
