Google site map problem

Hi,

I own a site wich sitemap is generated by my CMS.
It happens I have a certain amount of products now that my sitemap reached a size wich my host can not generate.

Lets say I have 24000 products in my site.
Every time I make an update I add about 2000 new products.

Google has indexed about 16000 of my products

Only the latest added products are linked from category pages. Once I make a new update the old 2000 products diapear and the new ones get linked from the category pages.

My question is:
If I show google a sitemap wich contains only the newest 2000 products will google delete my old products from their database?

Thanks for your opinion.

Try upload several sitemap instead combine it all into one

But I can not cover all my products with several sitemaps. Or at least the only good sitemap generator wich is this one http://www.xml-sitemaps.com/, will only add to the site map linked products. Many of my old products are not linked. Plus it has a limit of 500 products per sitemap.

Do you think if I upload 20 sitemaps, but they only show the last 2000 products to google, will they delete the products that are not shown in the 20 sitemaps ?

you want google to remove the old pages from its index??

Block them using a robots.txt file or a NOINDEX meta or perhaps both..IMHO..and then submit the sitemap of the new URL's..

No, Google won't delete any of the products just because they're not listed in the sitemap - this would only happen if you blocked them with a robots.txt file, or noindex meta tags, or the pages consistently returned 404 or 410 headers.

Google uses the xml sitemap in addition to it's normal crawl, so using the sitemap only for new products and recently updated products is perfectly reasonable (if you include updated products and use the last modified tag it will help Google bots recheck the relevant pages that much sooner than relying on normal crawl patterns).

You are talking about “Google Sitemap”. In Google Sitemap you are provide URL up to 50,000 and more than that, and other thing is that you should keep file size lower than 10MB. If you have URL more than 50,000, you can create multiple sitemaps.

TO all sho participated on this post.

Do you know any other good sitemap generator besides the one from google and this one http://www.xml-sitemaps.com/ ?

Christ!!, I dont want google to remove my pages.

Thanks for your opinion Jagnet.

My real problem is that I can not find a good sitemap generator. that gives the the possibility to create several sitemaps, with filesize below 8M, and with no URLs limitations.
