I am working on B2C web portal where URL rewriting is still remaining. There are 15+ static pages and remaining pages are dynamic. I want to develop XML sitemap and submit to Google webmaster tools. I suppose to optimize all URLs very soon and develop SEO friendly URLs. But, It may take some time. So, Can I submit XML sitemap to Google webmaster tools without rewriting it? I will submit again new XML sitemap after some time with latest URLs which will be SEO friendly.
