Hello,I have a blog and i want to create a store so if i create a wp page name as store online then it redirects to other site effect my ranking or not ???
If you add an extra page you will lose page rank and this will have a little effect on your rankings (adding a nofollow tag might help some). The strange redirection is odd, Don't quite understand why your no just linking to the store.
Adding a new page on your site is not going to affect your rankings... Yes it will take a miniscule amount of PR away from other pages, but PR has very little effect on rankings. And I agree w/ Nixies... I would not implement that as a 301 redirect. Simply add a link on your blog pointing to the store on the other site. No need for a 301. 301 is meant for when you USED to have a page of content at URL X but now it lives at URL Y.
Unable to understand Why you want redirection to Online Store.. any ways it really affect you ranking.. Try another method for redirection..
