URL redirect

simple redirect or 301 redirect

[memorygreetings]

I need suggestion about changing my older URL to new URL of the same page. Right now URL consists of ID only (http://url.com/show_sub_e_cats.asp?id=126), i wish to place relevent keywords in the url along with ID to get better chance for optimization. (http://url/dir/?CardTitle=keywords&cid=126)

I would like to know if in this case 301 redirect will be used on older URLS or any other redirect will do the job. Keep SEO,and previous link value of older URL in mind and suggest me what should it be.

You need to:

- link to the new URL from the links on your pages,
- redirect external requests for the old URLs to the new URLs,
- validate the cardtitle parameter value with the entry in the database and redirect if it is incorrect.
