Omar is correct that you cant have xml sitemap1, 2, 3 and so on, when submitting them to G-o-o-g-l-e, but you can have many sitemaps on a domain like your big domain but you will have to create a sitemap index, which is what u will submit to G-o-o-g-l-e
My sitemap
http://www.travel-e-store.com/sitemap.xml on the moment have 34842 urls and i am adding by the day.
My site map is added to G:eek::eek:GLE Webmaster Tools and under site map, all o.k as below.
You will however find the following in the help section:
Can I submit multiple Sitemaps at once?
You can provide multiple Sitemap files, but each Sitemap file that you provide must have no more than 50,000 URLs and must be no larger than 10MB when uncompressed. These limits help to ensure that your web server does not get bogged down serving very large files.
If you want to list more than 50,000 URLs, you must create multiple Sitemap files. If you anticipate your Sitemap growing beyond 50,000 URLs or 10MB, you should consider creating multiple Sitemap files. If you do provide multiple Sitemaps, you can list them in a Sitemap index file. A Sitemap index file can list up to 1,000 Sitemaps.
the following will be usefull for building the multiple pages sitemap
Sample XML Sitemap Index
The following example shows a Sitemap index in XML format. The Sitemap index lists two Sitemaps:
Sitemap index file
The XML format of a Sitemap index file is very similar to the XML format of a Sitemap file. The Sitemap index file uses the following XML tags:
* - the parent tag surrounds the file.
* - the parent tag for each Sitemap listed in the file (a child of )
* - the location of the sitemap (a child of )
* - the last modified date of the sitemap (optional)
See the Sitemap Protocol for more information.
Sample XML Sitemap Index
The following example shows a Sitemap index in XML format. The Sitemap index lists two Sitemaps:
http://www.example.com/sitemap1.xml.gz
2004-10-01T18:23:17+00:00
http://www.example.com/sitemap2.xml.gz
2005-01-01
Now that was the easy part, what i do not know is how you will build the seperate sitemaps, like sitemap 1, 2, 3 etc. I am sure there is a way, but that is something for he clever people like Omar to figure out
