I've a page that looks like: www.mysite.com/12345-test
12345 ==> a unique number
test ==> data that can be entered by a user (after login)
All the content on the page is coming from a database using the number in the url (12345). The 'test' part is not important to get the content, but gives more data to my visitors than a number.
1) If someone would link to this page with the following link: www.mysite.com/12345-teeeest
Than I can see in the database that 'teeeest' should be 'test' and I redirect the page to www.mysite.com/12345-test (using the php header function).
Can this give some seo problems?
2) Google knows this url: www.mysite.com/12345-test
Now the 'test' part is changed in the database to test2 and I redirect the page from www.mysite.com/12345-test to www.mysite.com/12345-test2
Can this give some seo problems? Google might see the same content on 2 different url's?
How to make sure all is ok for google?
