There are too many parameters in my url's and I want to rewrite them. The question is what will google do if I rewrite them?? Thanks Andy
Rewrite them and place a 301 redirect in your htaccess file from old to new URL and you will be fine.
It is better to rewrite the parameterized URLs with readable URLs. Include those URLs in the sitemap and submit the sitemaps to get indexed.
If you rewrite them properly, you will not be penalized. You can redirect from the old page to the new pages, but also remove the old pages from the Google indexed pages. The end result should be better.
Well if u do proper rewrite and makes proper 301 redirects than u will never be penalized, may be drop for sometime but after that ur site traffic will boost up bcoz static links are much better than dynamic one. Good Luck
If the rewrite or mapping is done properly, i don't feel there should be any issues. But better remove the earlier pages and also dont forget to add the new pages in ur xml and original sitemaps.
Google would not penalize your site by doing this but it could effect your ranking temporarily. The best thing you could do is 301 "each and every old page" to the new location. All old pages must not being 404 or your site would get penalized due to lost a lot of pages.
