Is it wrong to land on one page with two different link
For example
i owe a website

http: // www.  abc . com

PHP:

its working fine
and on Logo i had given link

http: // www.  abc . com / index.php

PHP:

and it is redirecting to main page

http: // www.  abc . com

PHP:

so is this concept wrong ?

 

If it's a 301 redirection then there's nothing wrong with the redirection, if your redirection is 302 temporary then Google might index double URLs

www.abc.com

Code (markup):

and

www.abc.com/index.php

Code (markup):

which might cause duplicate penalty issues.

 

Do a 301 redirect if its not done.
It should be done asap.

 

Redirecting is not a problem if you use of 301 redirect.You can do it from your hosting control panel.
