While surfing we do encounter web pages with almost same web address but having different Google Page Rank. This actually sounds amazing but it happens.
For a crawler or search engine spider www.domain.com/, domain.com/, www.domain.com/index.html and domain.com/index.html are entirely different urls. visitors reach at the site’s home page through any of the URLs, but crawlers see them as separate URLs, and it makes a difference when working out the PageRank. It is better to normalize or standardize the URLs you use for the site’s home page. Otherwise each url can end up with a different Google PageRank, whereas all of it should have gone to just one url.
below given examples/situations that happened with us are something like
situation 1
www.domain.com/link/ has PR = 5
www.domain.com/link/index.php has PR =1
situation 2
http://www.domain.com/link/ PR=3
http://www.domain.com/link PR=0
situation 3
http://www.domain.com/ PR=3
http://www.domain.com/index.php OR http://www.domain.com/home.php PR=2
Now the solutions
Change the pointing to Links
These are two slightly different URLs. Even if they drive you to the same content on domain, but technically they are not the same.
In this case we would advise that change all links for “Home” to point to http://www.domain.com/ and never to /index.php. This thing also applies to any directory level index pages, link them to http://www.domain.com/directory/
301 Redirect
301 redirect is one of the most useful and SEO freindly method for webpage redirection. It’s not that hard to implement and it will preserve your search engine rankings for a particular page.Some of the very common redirects are :-
- IIS Redirect
- Cold fusion Redirect
- PHP Redirect
- ASP Redirect
- ASP.Net Redirect
- Java Redirect
- Redirect old domain to new domain with htaccess Redirect
- Redirect to www with htaccess Redirect
Finally, It is very important that you do take care while submitting your links even a single slash can ruin your whole SEO hard work. Make sure you submit exactly the same URL everywhere for backlinks purpose.

The question is not that almost the same url with different ranks, but exactly the same url yet different ranks.
How you explain that?
