Hi Tedster, below are the answers of the questions. Please help me to solve this issue :)
1. Do you get much traffic - especially Google Search traffic - that requests the "index.php" URL?
I get the Google search traffic but I don't know how I can figure out which URL Google request, kindly explain.
I get to see the index.php URLs on the content section of the analytics.
2. What happens in Google if you enter one of those "index.php" URLs directly into the search box? Do you get a result?
If I enter in the Google http://www.domain.com/post-name/index.php
then it returns the original URL that I have set up which is http://www.domain.com/post-name/
3. When you enter an "index.php" URL into the nav bar and get redirected, what http status is returned in the server header?
