Google sitemaps

[JoeytheBrit]

I have a new website and was all prepared to submit a sitemap to Google when an acquaintance who is a website designer mentioned that submitting a sitemap can actually reduce the number of pages indexed by Google. Currently, Google only has around 5% of my site's pages indexed. Has anyone here had experience of this problem after submitting a sitemap to Google?

I don't know more about this. But my practise shows that when you submiting sitemap to google, it index faster and more accurate.
Hoping hear more opinions too

You have to make sure that your sitemap.xml has all the pages that you have.
